TMN Protocol Architecture and Selections

• 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?
• 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

Telecom. Markup Language (tML)

• tML is a specialization of the Extended Markup
  Language (XML) for the telecom industry
• An activity being worked in collaboration with
  T1M1
• Initial deliverable is a tML framework
