<pre>Network Working Group D. Walden
Request for Comments: #591 BBN-Net
NIC: #20327 29 November 1973
<span class="h1">Addition to the Very Distant Host Specification</span>
It has been brought to my attention that the following sentence
should be added to the Very Distant Host specification in <a href="#appendix-F">Appendix F</a> of
BBN report 1822, Specifications for the Interconnection of a Host and an
IMP, to the paragraph beginning on page F-5 and ending on page F-7:
"Null packets do not use a channel (nor a channel number) when sent and
are not acknowledged when received."
Please file this RFC with your copy of BBN report 1822 until 1822
is next updated.
