Brief Review of ProposalsEnd-to-End VoMPLS Header Compression(draft-ash-e2e-vompls-hdr-compress-00.txt) steps use RSVP to establish LSPs between CE1-CE2 use cRTP (or simple HC) to compress header at CE1, decompress at CE2 CE1 requests SCIDs from CE2 CE1 appends CE2 label to compressed header header compression context routed from CE1 --> PE1 --> P --> PE2 --> CE2 route compressed packets with MPLS labels CE1 --> CE2 packet decompressed at CE2 using cRTP (or simple HC) algorithm advantages minimizes PE requirements (has to route HC context) disadvantages CE’s need to run RSVP, possible scalability issue |
