RFC 3476 LDP & RSVP Extensions for Optical UNI Signaling March 2003
2. LDP Extensions for UNI Signaling
The LDP extensions for UNI signaling consist of new TLVs that capture
UNI-specific parameters and new UNI-specific status codes. The new
TLVs are Source ID (3 TLVs), Destination ID (3 TLVs), Egress Label,
Local Connection ID, Diversity, Contract ID, and UNI Service Level
[8]. These are described below. The new status codes are assigned
from the private use space of LDP codes, as described in [8]. The
UNI specification [8] also defines two new LDP messages, Status
Enquiry and Status Response. These messages have been obsoleted and
hence no code points are requested in this document for them.
2.1 Source ID TLVs
Three TLVs have been defined to encode the Source ID. The content and
usage of these TLVs are described in [8].
