8 6-8 October 2003 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 v3 or v2c with TLS over TCP (no access control); SNMP v3 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
