   3 This directory provides programs that measure the round trip latency
   4 of synchronous octet messaging using ACE wrapper-facades for the SCTP
   5 protocol. Currently these programs provide the only example code on
   6 how to use ACE's wrapper-facades for SCTP. In the future additional
   7 code will be placed in the ACE_wrappers/examples/IPC_SAP/SOCK_SAP
   8 directory.
   9
  10 SOCK_STREAM_clt and SOCK_STREAM_srv use the SOCK_STREAM service
  11 provided by SCTP via ACE's SOCK_Connector, SOCK_Stream,
  12 SOCK_Association wrapper-facade classes.
  13
  14 SOCK_SEQPACK_clt and SOCK_SEQPACK_srv use the SOCK_SEQPACKET service
  15 provided by SCTP via ACE's SOCK_SEQPACK_Connector,
  16 SOCK_SEQPACK_Association and SOCK_SEQPACK_Acceptor wrapper-facade
  17 classes.
  18
  19 The following table provides a summary of relationships between two main
  20 Linux SCTP implementations (OpenSS7 and LKSCTP), and ACE Wrapper Facades
  21 support that is provided. Built on top of the ACE Wrapper Facade support is
  22 the SCIOP support in TAO. SCIOP works identically on both OpenSS7 and
  23 LKSCTP implementations. Please read additional README* files listed below.
