/*
|
|
* NOTES
|
|
*
|
|
* This module defines routines to disassemble RSVP packets, as defined in
|
|
* RFC 2205. All objects from RFC2205 are supported, in IPv4 and IPv6 mode.
|
|
* In addition, the Integrated Services traffic specification objects
|
|
* defined in RFC2210 are also supported.
|
|
*
|
|
* IPv6 support is not completely tested
|
|
*
|
|
* Mar 3, 2000: Added support for MPLS/TE objects, as defined in
|
|
* <draft-ietf-mpls-rsvp-lsp-tunnel-04.txt>
|
|
*
|
|
* May 6, 2004: Added support for E-NNI objects, as defined in
|
|
* <OIF-E-NNI-01.0> (Roberto Morro)
|
|
* <roberto.morro[AT]tilab.com>
|
|
*
|
|
* May 6, 2004: Modified some UNI objects, as defined in
|
|
* <OIF2003.249.09> (Roberto Morro)
|
|
* <roberto.morro[AT]tilab.com>
|
|
*
|
|
* June 2, 2005: Modified more UNI objects to show correct TNA
|
|
* addresses; Fixed LSP interface ID subobject (Richard Rabbat)
