This document makes performance-related recommendations for users of
network paths that traverse "very low bit-rate" links.
"Very low bit-rate" implies "slower than we would like". This
recommendation may be useful in any network where hosts can saturate
available bandwidth, but the design space for this recommendation
explicitly includes connections that traverse 56 Kb/second modem
links or 4.8 Kb/second wireless access links - both of which are
This document discusses general-purpose mechanisms. Where
application-specific mechanisms can outperform the relevant
general-purpose mechanism, we point this out and explain why.
This document has some recommendations in common with RFC 2689,
"Providing integrated services over low-bitrate links", especially
in areas like header compression. This document focuses more on
traditional data applications for which "best-effort delivery" is
