/*
|
|
* NOTES
|
|
*
|
|
* This module defines routines to disassemble RSVP packets, as defined in
|
|
* RFC 2205. All objects from RC2205 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>
