TMN Protocol Architecture and Selections o Recommendation M. 3017 (Framework for the integrated management of hybrid circuit/packet-IP networks) classifies TMN management paradigms as • general purpose: OSI systems management (CMIP/GDMO); CORBA 2. 3 or more recent • special purpose: EDI (for X interface only); SNMP (not X); CORBA 2. 1? o Q. 811 (Lower layer protocols) and Q. 812 (upper layer protocols) to be revised to support selected IETF protocols • current SG 4 position regarding SNMP — two candidate stacks: SNMP v 3 or v 2 c with TLS over TCP (no access control); SNMP v 3 with user security model over UDP (as a forward looking stack) — any stack should support authentication — the special purpose of each stack should be described 6 -8 October 2003 8
