<span class="h2"><a class="selflink" id="section-1" href="#section-1">1</a>.  Introduction</span>

   The SatLabs Group [<a href="#ref-SATLABS">SATLABS</a>] is an international non-profit EEIG
   (European Economic Interest Grouping) committed to large-scale
   adoption and deployment of the Digital Video Broadcasting Return
   Channel via Satellite (DVB-RCS) standard [<a href="#ref-ETSI-RCS" title="&quot;Digital Video Broadcasting (DVB); Interaction Channel for Satellite Distribution Systems&quot;">ETSI-RCS</a>].  SatLabs members
   are service providers, satellite operators, system integrators,
   terminal manufacturers, and technology providers with an interest in
   DVB-RCS.

   Since its creation in 2001, the main goal of the SatLabs Group has
   been to achieve interoperability between DVB-RCS terminals and
   systems.  Therefore, the Group has defined the SatLabs Qualification
   Program, which provides an independent certification process for DVB-
   RCS terminals based on System Recommendations defined by SatLabs.  To
   enhance product interoperability, beyond the physical-layer and MAC-
   layer mechanisms defined in the DVB-RCS standard, SatLabs has
   expanded its Recommendations in the field of DVB-RCS terminal
   management [<a href="#ref-SATLABS">SATLABS</a>].  As part of this effort, SatLabs has specified
   a common Simple Network Management Protocol (SNMP) Management
   Information Base (MIB) for DVB-RCS terminals, which is defined in
   this document.

   A DVB-RCS terminal is denoted as a Return Channel Satellite Terminal
   (RCST) in the remainder of this document.  This consists of an Indoor
   Unit (IDU) and an Outdoor Unit (ODU) connected through an Inter-
   Facility Link (IFL), usually a coaxial L-band interface.  On the user
   side, the IDU is connected to the user network through a Local Area
   Network (LAN) interface (usually Ethernet).  On the network side, the
   ODU is connected via a satellite link (the air interface).

   The SatLabs Group DVB-RCS MIB is implemented in the IDU of an RCST.
   RCST management can be performed either through the LAN interface
   (local management) or through the air interface (remote management
   from the Network Control Center, NCC).  RCST and NCC elements are
   shown on Figure 1.

   This memo defines a portion of the Management Information Base (MIB)
   for use with network management protocols in the Internet community.

   For a detailed overview of the documents that describe the current
   Internet-Standard Management Framework, please refer to <a href="./rfc3410#section-7">section&nbsp;7 of
   RFC 3410</a> [<a href="./rfc3410" title="&quot;Introduction and Applicability Statements for Internet- Standard Management Framework&quot;">RFC3410</a>].

   Managed objects are accessed via a virtual information store, termed
   the Management Information Base or MIB.  MIB objects are generally
   accessed through the Simple Network Management Protocol (SNMP).
   Objects in the MIB are defined using the mechanisms defined in the
   Structure of Management Information (SMI).  This memo specifies a MIB
   module that is compliant to the SMIv2, which is described in STD 58,
   <a href="./rfc2578">RFC 2578</a> [<a href="./rfc2578" title="&quot;Structure of Management Information Version 2 (SMIv2)&quot;">RFC2578</a>], STD 58, <a href="./rfc2579">RFC 2579</a> [<a href="./rfc2579" title="&quot;Textual Conventions for SMIv2&quot;">RFC2579</a>] and STD 58, <a href="./rfc2580">RFC 2580</a>

<span class="h4"><a class="selflink" id="section-2.2.1" href="#section-2.2.1">2.2.1</a>.  Star DVB-RCS Network</span>

   This denotes a hub-and-spoke configuration where all communications
   pass through a central hub, which usually also includes the NCC.
   Peer-to-peer communication between RCSTs is possible through a double
   satellite hop (this traffic has to pass through the hub).

<span class="h4"><a class="selflink" id="section-2.2.2" href="#section-2.2.2">2.2.2</a>.  Mesh DVB-RCS Network</span>

   This denotes a network using transparent satellite transponders.
   Star or mesh network configurations can be supported.  In the case of
   a mesh configuration, RCSTs need to incorporate a TDMA receiver in
   addition to the TDM receiver.

<span class="h4"><a class="selflink" id="section-2.2.4" href="#section-2.2.4">2.2.4</a>.  Regenerative DVB-RCS Network</span>

   This denotes a network that uses regenerative satellite transponders,
   i.e.  includes some On-Board Processing functionality, which allows
   demodulation and decoding of the uplink TDMA signals and re-multiplex
   of the traffic into TDM signals on the downlink.  Star or mesh
   network configurations can be supported.

   The CW frequency is the frequency of a Continuous Wave signal.  It is
   a narrowband carrier transmitted for the duration of measurements
   during the installation of an RCST.

<span class="h4"><a class="selflink" id="section-2.2.17" href="#section-2.2.17">2.2.17</a>.  Request Class</span>

   A Request Class (RC) is a representation of a Per-Hop Behavior (PHB)
   at the MAC layer.  It defines a behavior of the MAC layer for a given
   aggregation of traffic.  This behavior includes a combination of
   Capacity Categories associated to the RC and a priority with respect
   to the other RCs supported by an RCST.

<span class="h4"><a class="selflink" id="section-2.2.20" href="#section-2.2.20">2.2.20</a>.  MPEG Profile</span>

   The MPEG profile is one of the two profiles for traffic burst format
   on the DVB-RCS TDMA.  It is based on a number of concatenated
   MPEG2-TS packets, each of length 188 bytes.

<span class="h4"><a class="selflink" id="section-2.2.21" href="#section-2.2.21">2.2.21</a>.  PID Pool</span>

   For the MPEG profile, several RCs may be mapped within a pool of
   several PIDs to allow cross-RC Section Packing [<a href="#ref-ETSI-DAT" title="&quot;Digital Video Broadcasting (DVB); DVB Specifications for Data Broadcasting&quot;">ETSI-DAT</a>].  Section
   Packing can be used on all PIDs and higher priority traffic can
   always preempt lower priority streams.  This reduces the need for
   padding.

<span class="h4"><a class="selflink" id="section-2.2.22" href="#section-2.2.22">2.2.22</a>.  Capacity Categories</span>

   The TDMA timeslot allocation process for the DVB-RCS uplink supports
   several Capacity Categories.

   The Capacity Categories CRA, RBDC, and A/VBDC, when authorized for an
   RC, have to be configured from the NCC.  Their configuration
   parameters are used to inform the RCST of the configuration of each
   category at the NCC side and thus help in Capacity Requests
   computation.

   The categories are treated independently for each RC.  A SatLabs
   optional feature is defined that allows their configuration at the
   RCST level in addition to configuration per RC.  This feature is
   denoted RCST_PARA.

<span class="h5"><a class="selflink" id="section-2.2.22.1" href="#section-2.2.22.1">2.2.22.1</a>.  Continuous Rate Assignment (CRA)</span>

   CRA is a rate capacity that is provided in full in a continuous
   manner to the RCST while required.

   RBDC is a rate capacity that is requested dynamically by an RCST.
   RBDC is provided in response to explicit requests from the RCST to
   the NCC, such requests being absolute (i.e., corresponding to the
   full rate currently being requested).  Each request overrides all
   previous RBDC requests from the same RCST and is subject to a maximum
   rate limit.

<span class="h5"><a class="selflink" id="section-2.2.22.3" href="#section-2.2.22.3">2.2.22.3</a>.  Volume-Based Dynamic Capacity (VBDC)</span>

   VBDC is a volume capacity that is requested dynamically by an RCST.
   VBDC is provided in response to explicit requests from the RCST to
   the NCC, such requests being cumulative (i.e., each request adds to
   all previous requests from the same RCST).

<span class="h5"><a class="selflink" id="section-2.2.22.4" href="#section-2.2.22.4">2.2.22.4</a>.  Absolute Volume-Based Dynamic Capacity (AVBDC)</span>

   AVBDC is a volume capacity that is requested dynamically by an RCST.
   This capacity is provided in response to explicit requests from the
   RCST to the NCC, such requests being absolute (i.e., this request
   replaces the previous ones from the same RCST).

   The combination of AVBDC and VBDC is seen as a single Capacity
   Category, denoted A/VBDC.

   VCM: In VCM transmission mode, the forward link uses transmission
        parameters that are variable on a BBFRAME-by-BBFRAME but fixed
        on a Receiver basis, according to fixed link and propagation
        conditions for each Receiver.

   ACM: In ACM transmission mode, the forward link uses transmission
        parameters that are dynamically adjusted on a BBFRAME-by-BBFRAME
        and Receiver-per-Receiver basis, according to actual link and
        propagation conditions.  In order to implement ACM, feedback
        from each Receiver has to be provided by DVB-RCS return channel.

   This MIB module provides a set of objects required for the management
   of a SatLabs-compliant RCST.  The specification is derived from the
   parameters and protocols described in [<a href="#ref-SATLABS">SATLABS</a>].

   The MIB module in this document uses the following OBJECT IDENTIFIER
   values, as already assigned by IANA under the smi-numbers registry
   [<a href="#ref-IANA" title="&quot;Internet Assigned Numbers Authority&quot;">IANA</a>]:

         +------------+---------------------------+
         | Descriptor | OBJECT IDENTIFIER value   |

   functionality, with impact on interoperability, and their support is
   advertised with the RCST certification level.

   DvbRcsSystemSatLabsFeatureMap represents the SatLabs optional
   features supported as defined in [<a href="#ref-SATLABS">SATLABS</a>].  These represent minor
   features, not necessary for interoperability.  They are not used for
   the certification of SatLabs terminals.

<span class="h3"><a class="selflink" id="section-3.2" href="#section-3.2">3.2</a>.  Structure of the MIB</span>

   This MIB module is structured into two top-level groups:

   o  The dvbRcsMibObjects group includes all the managed objects of the
      DVB-RCS MIB.

   o  The dvbRcsConformance group includes the compliance statements for
      DVB-RCS terminals that are compliant with [<a href="#ref-SATLABS">SATLABS</a>].  The managed
      objects are grouped into formal object groups (i.e., units of
      conformance) according to their relation to specific SatLabs
      options or features.  The conformance statements (MODULE-
      COMPLIANCE specification) are described within the
      dvbRcsRcstCompliances group, while the units of conformance are
      described within the dvbRcsRcstGroups group.

   The dvbRcsMibObjects group is further structured into three groups:
   dvbRcsRcst, dvbRcsFwdLink, and dvbRcsRtnLink.

   The dvbRcsRcst group covers management related to the RCST equipment.
   It is structured into six groups:

   o  dvbRcsRcstSystem

   o  dvbRcsRcstNetwork

   o  dvbRcsRcstInstall

   o  dvbRcsRcstQos

   o  dvbRcsRcstControl

   o  dvbRcsRcstState

   The dvbRcsFwdLink group covers management information related to the
   RCST forward link.  It is structured into two groups:

   o  dvbRcsFwdConfig

   o  dvbRcsFwdStatus

   The dvbRcsRtnLink group covers management information related to the
   RCST return link.  It is structured into two groups:

   o  dvbRcsRtnConfig

   o  dvbRcsRtnStatus

   Tables within each of these groups cover different functions like
   return link traffic management (packet classes, Request Classes, PID
   pools) and forward link configuration and status.

   Rows created automatically (e.g., by the device according to the
   hardware configuration) may, and generally will, have a mixture of
   configuration and status objects within them.  Rows that are meant to
   be created by the management station are generally restricted to
   configuration (read-create) objects.

<span class="h3"><a class="selflink" id="section-3.3" href="#section-3.3">3.3</a>.  Relationship to the Interfaces MIB Module</span>

   This section clarifies the relationship of this MIB module to the
   Interfaces MIB [<a href="./rfc2863" title="&quot;The Interfaces Group MIB&quot;">RFC2863</a>].  Several areas of correlation are addressed
   in the following.  The implementer is referred to the Interfaces MIB
   document in order to understand the general intent of these areas.

   IANA has assigned three ifType labels for DVB-RCS.  Each RCST MUST
   support at least the three following interfaces:

   o  dvbRcsMacLayer (239), -- DVB-RCS MAC Layer

      DVB-RCS MAC Layer represents the complete air interface of an
      RCST, as specified in [<a href="#ref-ETSI-RCS" title="&quot;Digital Video Broadcasting (DVB); Interaction Channel for Satellite Distribution Systems&quot;">ETSI-RCS</a>].  This interface supports star
      and mesh networks and is bi-directional.  Only star networks are
      considered by the present MIB module.

   o  dvbTdm (240), -- DVB Satellite TDM

      DVB-RCS physical link based on Time-Division Multiplexing.  It
      corresponds to the forward link of an RCS transparent system or
      the downlink of an RCS regenerative system.  It is based on either
      the DVB-S or DVB-S2 standard, specified in [<a href="#ref-ETSI-DVBS" title="&quot;Digital Video Broadcasting (DVB); Modulation and Coding for DBS satellite systems at 11/12 GHz&quot;">ETSI-DVBS</a>] and
      [<a href="#ref-ETSI-DVBS2" title="&quot;Digital Video Broadcasting (DVB); Second generation framing structure, channel coding and modulation systems for Broadcasting, Interactive Services, News Gathering and other broadband satellite applications&quot;">ETSI-DVBS2</a>] respectively.  Only transparent systems are
      considered by the present MIB module.

      In the DVB-RCS context, this interface is uni- or bi-directional.

      In the present MIB module, only a uni-directional (i.e., forward
      link, or downstream) dvbTdm interface is considered.

   o  dvbRcsTdma (241), -- DVB-RCS TDMA

      DVB-RCS physical link based on Time-Division Multiple Access.  It
      corresponds to the return or mesh link of an RCS transparent
      system or the uplink of an RCS regenerative system.  It is based
      on the DVB-RCS standard specified in [<a href="#ref-ETSI-RCS" title="&quot;Digital Video Broadcasting (DVB); Interaction Channel for Satellite Distribution Systems&quot;">ETSI-RCS</a>].

      In the context of star transparent and mesh regenerative DVB-RCS
      systems, this interface is uni-directional.

      In the context of mesh transparent DVB-RCS systems, this interface
      is bi-directional.

      Only star transparent systems are considered by the present MIB
      module (i.e., return link, or upstream).

   The protocol stack (as reflected in ifStackTable) will be as follows:

           +--------------------------+
           |            IP            |
           +--------------------------+
           |      dvbRcsMacLayer      |
           +---------------+----------+
           |  dvbRcsTdma   | dvbTdm   |
           +---------------+----------+
           |   MPEG/ATM    | MPEG/GS  |
           +---------------+----------+

           Figure 2: RCST Protocol Stack

   An additional Ethernet interface is used on the LAN side of the RCST
   (see Figure 1).

   An instance of ifEntry exists for each dvbTdm interface, for each
   dvbRcsTdma (normally only one), and for each dvbRcsMac layer
   (normally only one).

   The interface counters relate to:

   o  dvbRcsMacLayer: DVB-RCS two-way MAC interface that counts
      aggregate Multi-Protocol Encapsulation (MPE) frames, Generic
      Stream Encapsulation (GSE) encapsulated PDUs (equals IP packets),
      and ATM Adaptation Layer 5 (AAL5) frames.

   MPE is specified in [<a href="#ref-ETSI-DAT" title="&quot;Digital Video Broadcasting (DVB); DVB Specifications for Data Broadcasting&quot;">ETSI-DAT</a>] and is transported over MPEG, which is
   specified in [<a href="#ref-ISO-MPEG" title="&quot;Information Technology; Generic Coding of Moving Pictures and Associated Audio Information Systems&quot;">ISO-MPEG</a>].  MPEG is transported over GS or TS

   GSE is specified in [<a href="#ref-ETSI-GSE" title="&quot;Digital Video Broadcasting (DVB); Generic Stream Encapsulation (GSE) Protocol&quot;">ETSI-GSE</a>] and is transported over the GS

   AAL5 is specified in [<a href="#ref-ITU-AAL5" title="&quot;B-ISDN ATM Adaptation Layer specification: Type 5 AAL&quot;">ITU-AAL5</a>].

   o  dvbTdm: The DVB-RCS TDM interface that counts MPEG TS packets at
      stream level, if the TS format is used.  If the Generic Stream
      (GS) format is used, it counts GSE packets.

   o  dvbRcsTdma: The DVB-RCS TDMA interface that counts aggregate ATM
      and MPEG TS packets.

   The ifStackTable [<a href="./rfc2863" title="&quot;The Interfaces Group MIB&quot;">RFC2863</a>] MUST be implemented to identify the
   relationships among sub-interfaces.

   The following example is a DVB-RCS star network with DVB-S and DVB-
   RCS.  As illustrated on Figure 3, it shows a DVB-RCS MAC interface
   with one downstream and one upstream interface.  In this network, ATM
   encapsulation is used in the DVB-RCS uplink.  Two ATM Logical Ports
   are shown.  DVB-S2 or DVB-S can be used in the downlink.

   ifType 214 'mpegTransport' can also be used for counting TS packets
   and bytes for sub-interfaces of dvbRcsTdma or dvbTdm, e.g., per PID-
   oriented or per TS-oriented, as desired and applicable.

   As can be seen from this example, the dvbRcsMacLayer interface is
   layered on top of the downstream and upstream interfaces, and the
   upstream interface is layered on top of upstream ATM logical links.

   The MIB objects in this group gather some basic information that
   would allow anyone to trace the history -- the life -- of the RCST,
   as well as to get a complete description of its constitution on the
   component point of view, including the SatLabs options/features
   support statement.  Many of the parameters will be defined at
   installation.

   This group contains description parameters related to the RCST type
   (ODU type) and location.  These parameters are believed to stay
   unchanged once it has been defined during installation.  Modification
   of hardware equipment, maintenance operations, and geographical re-
   location may require an update of those MIB objects.  Note that the
   dvbRcsRcstSystem.dvbRcsSystemLocation object gives the location of

   the ODU antenna, which is needed for network operation, while the
   system.sysLocation (MIB-II SNMP OID) provides the location of the IDU
   unit, which cannot be used for the same purpose.

   The RCST must provide either Read-Write access to dvbRcsSystemOdu
   parameters or, alternatively, provide the list of supported devices
   through the dvbRcsRcstOduListGroup (see conformance section).  This
   group of parameters, defined in the dvbRcsRcstSystem group, allows
   the selection by the RCST installer of the actual ODU type.  In such
   a case, the installer must set dvbRcsOduTxType, dvbRcsOduRxType, and
   dvbRcsOduAntennaType according to the selected BUC, LNB, and antenna
   respectively.

<span class="h4"><a class="selflink" id="section-3.4.2" href="#section-3.4.2">3.4.2</a>.  dvbRcsRcstNetwork</span>

   This group contains all the MIB objects related to network
   parameters.

   In this subgroup, two objects have been defined in order to
   differentiate between control and user traffic and associate them
   with a physical interface.  Both
   dvbRcsRcstNetwork.dvbRcsNetworkLanIpAddress (Traffic) and
   dvbRcsRcstNetwork.dvbRcsNetworkOamInetAddress (OAM) provide the value
   of the IP address of, respectively, the user traffic and the control
   and management traffic.

   installation and commissioning.  Many parameters are believed to stay
   unchanged once it has been defined during installation.  Modification
   of hardware equipment, maintenance operations, and geographical re-

   This group contains objects to configure the Quality of Service (QoS)
   of the RCST by the NCC.

   The dvbRcsPktClass table defines the packet classification for IP
   layer 3 classifications.  Each dvbRcsPktClass entry is mapped to a
   dvbRcsPhbEntry in the dvbRcsPhbMappingTable.

   The dvbRcsPhbMappingTable makes the relation between a packet
   classification entry, a Per-Hop Behavior (PHB) identifier, and a
   Request Class entry.

   This MIB group contains parameters that enable access to data about
   the forward link.

   Configuration information is kept in the
   dvbRcsFwdLink.dvbRcsFwdConfig subgroup.  Status information is kept
   into the dvbRcsFwdLink.dvbRcsFwdStatus subgroup.

   The information in dvbRcsFwdLink.dvbRcsFwdConfig.dvbRcsFwdStartTable
   is used for the first time the RCST tries to acquire the forward
   link.  All these object values are aligned with the Satellite
   Delivery System Descriptor in the Network Information Table (NIT)
   table [<a href="#ref-ETSI-SI" title="&quot;Digital Video Broadcasting (DVB); Specification for Service Information (SI) in DVB Systems&quot;">ETSI-SI</a>].

   The objects in the dvbRcsFwdLink.dvbRcsFwdConfig.dvbRcsFwdStatusTable
   are aligned with the satellite forward path descriptor from the RCS
   Map Table (RMT) [<a href="#ref-ETSI-RCS" title="&quot;Digital Video Broadcasting (DVB); Interaction Channel for Satellite Distribution Systems&quot;">ETSI-RCS</a>] and with the Physical Layer (PL) Header

   the return link.

   Configuration information is kept in the
   dvbRcsRtnLink.dvbRcsRtnConfig subgroup.  Status information is kept
   into the dvbRcsRtnLink.dvbRcsRtnStatus subgroup.

   The RCST is only able to deal with one return link at a time.  Hence,
   there is no need to define a table to collect the different SNMP
   objects, as it is done for the forward.

<span class="h2"><a class="selflink" id="section-5" href="#section-5">5</a>.  Security Considerations</span>

   This MIB module relates to a system that allows end users to access a
   private network or public Internet access.  As such, improper
   manipulation of the MIB objects represented by this MIB module may
   result in denial of service to a large number of end users.

   There are a number of management objects defined in this MIB module
   with a MAX-ACCESS clause of read-write and/or read- create.  Such
   objects may be considered sensitive or vulnerable in some network
   environments.  The support for SET operations in a non-secure
   environment without proper protection can have a negative effect on
   network operations.  These are the tables and objects and their
   sensitivity/vulnerability:

   o  The use of the dvbRcsNetworkNccMgtInetAddress object to specify
      management stations is considered only limited protection and does
      not protect against attacks that spoof the management station's IP
      address.  The use of stronger mechanisms, such as SNMPv3 security,
      should be considered, where possible.

   o  The dvbRcsSystemOdu objects, dvbRcsCtrlCwEnable,
      dvbRcsRtnConfigMaxEirp, dvbRcsRtnConfigDefIfLevel objects, and
      dvbRcsRcstInstall sub-tree can, if improperly or maliciously used,
      lead to unwanted emissions or emission levels on the satellite
      uplink, thereby resulting in potential degradation of the RCS
      service or other services using the frequency band being used.

   o  The RCST may have its configuration file changed by the actions of
      the management system using a combination of the following
      objects: dvbRcsNetworkInstallLogFileDownloadUrl,
      dvbRcsCtrlDownloadFileCommand,
      dvbRcsCtrlActivateConfigFileCommand, or dvbRcsCtrlRebootCommand.
      An improper configuration file download may result in substantial
      vulnerabilities and the loss of the ability of the management
      system to control the satellite terminal.

   o  Setting dvbRcsNetworkLogFileUploadUrl to a wrong address may
      potentially impact debugging/troubleshooting efforts.

   o  Setting objects in dvbRcsPktClassTable could cause significant
      changes to default traffic filtering on an RCST.

   Some of the readable objects in this MIB module (i.e., objects with a
   MAX-ACCESS other than not-accessible) may be considered sensitive or
   vulnerable in some network environments.  It is thus important to
   control even GET and/or NOTIFY access to these objects and possibly
   to even encrypt the values of these objects when sending them over

   the network via SNMP.  These are the tables and objects and their
   sensitivity/vulnerability:

   o  The dvbRcsNetworkNccMgtInetAddress object may provide sufficient
      information for attackers to spoof management stations that have
      management access to the device.

   o  The dvbRcsRcstCurrentSoftwareVersion object may provide hints as
      to the software vulnerabilities of the RCST.

   o  The object dvbRcsNetworkOamInetAddress and the table
      dvbRcsPktClassTable may provide clues for attacking the RCST and
      other subscriber devices.

   SNMP versions prior to SNMPv3 did not include adequate security.
   Even if the network itself is secure (for example by using IPsec),
   even then, there is no control as to who on the secure network is
   allowed to access and GET/SET (read/change/create/delete) the objects
   in this MIB module.

   It is RECOMMENDED that implementers consider the security features
   provided by the SNMPv3 framework (see <a href="./rfc3410#section-8">[RFC3410], section&nbsp;8</a>),
   including full support for the SNMPv3 cryptographic mechanisms (for
   authentication and privacy).

   Further, deployment of SNMP versions prior to SNMPv3 is NOT
   RECOMMENDED.  Instead, it is RECOMMENDED to deploy SNMPv3 and to
   enable cryptographic security.  It is then a customer/operator
   responsibility to ensure that the SNMP entity giving access to an
   instance of this MIB module, is properly configured to give access to
   the objects only to those principals (users) that have legitimate
   rights to indeed GET or SET (change/create/delete) them.
