Aggregation Aggregation must be supported (from NSIS Req’s) E2E reservations only handled at edges of ‘aggregation region’ Aggregation can be achieved by: Layered reservations (a bit like RFC 3175) Tunnelling (a bit like RFC 2746) Open issues: Is aggregation a special requirement to a QoS NSLP? Tells us whether some aspects should be handled at NTLP level How to realize aggregation within the protocol? Independent (and differently acting) protocol layers within NSLP? Multiple QoS objects with nested scope in one message? Separate NTLP/NSLP instances for per-flow/aggregate? Are both S-mode and R-mode needed for the aggregate? |
