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

models
o coarse-grained IDL modelling and basic application
models:
• X.780.1: TMN guidelines for defining coarse-grained
CORBA managed object interfaces
• Q.816.1: CORBA-based TMN service extensions to support
coarse-grained interfaces
• Q.816 amendment to profile OMG services
• M.3120: addition of coarse-grained managed objects
• Q.821.1: CORBA alarm management model
• Q.822.2: CORBA-based TMN performance management
