SCTP Agents</H1><P>This chapter describes the SCTP agents developed for by the Protocol Engineering Lab at the University of Delaware. The SCTP agents are all two-way agents, which means they are symmetric in the sense that they represent both a sender and receiver. However, bi-directional data has not yet been implemented. Each instance of an SCTP agent is either a sender or receiver.<P>The SCTP agents are implemented in files matching the regular expression <EM>sctp/sctp*.{cc, h}</EM>.<P>The SCTP agents currently supported are:<P><UL><LI>Agent/SCTP - RFC2960 + draft-ietf-tsvwg-sctpimpguide-04.txt + draft-ietf-tsvwg-usctp-01.txt<P></LI><LI>Agent/SCTP/Newreno - includes Fast Recovery introduced in draft-ietf-tsvwg-sctpimpguide-08.txt<P></LI><LI>Agent/SCTP/HbAfterRto - experimental extension (HEARTBEAT after RTO)<P></LI><LI>Agent/SCTP/MultipleFastRtx - experimental extension (UD PEL's Multiple Fast Retransmit algorithm)<P></LI><LI>Agent/SCTP/Timestamp - experimental extension (TIMESTAMP chunk)<P></LI></UL><P>Section <A HREF="node403.html#sec:baseSctp" tppabs="http://www.isi.edu/nsnam/ns/doc/node403.html#sec:baseSctp">32.1</A> provides a simple overview of the base SCTP agent with details of configuration parameters and commands.
