Some Explaination of MPLS Code
August 29, 2000
- MPLS CODE IS HIGHLY EXPERIMENTAL AND IS NOT THOROUGHLY TESTED. YOU
SHOULD CAREFULLY VALIDATE IT FOR YOUR SPECIFIC USAGE. IF YOU FIND
ANY BUG, OR HAVE ANY PATCH, PLEASE SEND TO ns-users@isi.edu
- It does not work with multicast routing, particularly because (1)
there is no label setup mechanism for multicast groups, (2) there is
no multicast replicator to cooperate with MPLS classifier, and (3)
MPLS header contain pointers, which do not work with multicast
replicator.
- It works only with flat unicast routing but not hierarchical routing
in any form. This is because current node-config architecture only
provides exclusive node types, namely, a node cannot supports
hierarchical routing and MPLS at the same time.
- Some interfaces in MPLS classifier and MPLS node are expected to
change in the near future to accomodate a new design of node-config
mechanism.
- There are no simple example files of MPLS code, because the ones in
MPLS test suite are enough to serve as examples. Please read
tcl/test/test-suite-mpls.tcl.
