Design Options (2) Issue: Which NSLP information should be diagnosed? Option 1: supported NSLP-IDs in each GIST node Pro: simple Cons: not useful enough? Recall GIST only talks to the next node supporting the requested NSLP Possible presence: take it, but add a bit more info Whether is a FW or NAT, QOSM-ID info etc. Option 2: aggregated NSLP state information in each GIST node Pro: may be useful Cons: how? Authorization issue? Option 3: all detailed individual NSLP state information Pros: Authorization issue; message too large? Open issue: authorization issue: who can issue the query? Proposal: Only sysadm to query Option 2, Option 1 handled less strictly |
