ITU-T SG 4 Work Program (1/4) • Working Party 1/4 - Designations, performance, and test equipment • Q 2/4: Designations for interconnections among network operators • Q 3/4: Transport network and service operations procedures for performance and fault management • Q 4/4: Test and measurement techniques and instrumentation for use on telecommunication systems and their constituent parts • Q 5/4: Jitter and wander test and measurement techniques and instrumentation for use on telecommunication systems and their constituent parts
ITU-T SG 4 Work Program (2/4) • Working Party 2/4: Common telecommunication management capabilities • Q 7/4: TMN principles and architecture • Q 8/4: Requirements for the TMN user interfaces • Q 9/4: Requirements for the TMN X interface • Q 10/4: Framework for unified management of integrated circuit-switched and packet-based networks (with an initial emphasis on IP-based networks) • Q 11/4: Principles of the customer network management and network-network management
ITU-T SG 4 Work Program (3/4) • Working Party 3/4: Telecommunication management information modelling • Q 12/4: Methodology and generic information models for TMN interfaces • Q 13/4: Generic network level management of transmission systems • Q 14/4: Management models for ANT and ATM network elements, including the support of access signaling and IP • Q 16/4: TMN management support for IMT-2000 and IN
ITU-T SG 4 Work Program (4/4) • Working Party 4/4: Telecommunication management infrastructure capabilities • Q 17/4: Open distributed management infrastructure • Q.18/4: Protocols to support operations, administration, and maintenance at the F, Q, and X interfaces • Q.19/4: Information models for management applications related to switching and generic support services
Current IETF WGs of interest to SG 4 • Q 3/4: ippm, bmwg • Q 4/4: ippm • Q 9/4: ippm • Q 10/4: all WGs on this chart • Q 12/4: atommib, snmpconf • Q 13/4: snmpconf • Q 14/4: snmpconf, adslmib • Q 18/4: snmpv3, sming, ldapv3, pkix • Q 19/4: policy, AAA, disman, rap, gsmp
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
TMN CORBA Infrastructure • fine-grained IDL modelling: • X.780: TMN guidelines for defining CORBA managed objects • Q.816: CORBA-based TMN services • M.3120: CORBA generic network and NE level information models • 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 service • X.781: Guidelines for CORBA ICS proformas
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
IETF and Other Org. Related Activities • Exchange of work overview between SG 4 and IETF • DISMAN group, Alarm MIB, AAA… • JointNM: an informal gathering of leaders and participants from SG 4 (Q 10/4), ETSI TIPHON, T1M1, TMForum, and IETF • Information exchange via liaison statement with ETSI TIPHON, TMForum, T1M1, and IETF • TMForum Submit eTOM document to SG4 for ITU-T approval Nov. 2003 SG4 meeting • Draft Recommendation M.1401 on Formalization of interconnection designations is scheduled for Consent in Nov. 2003 SG4 meeting • Draft new Recommendation M.3350 Emergency Telecommunication Service candidate for a Consent in Nov. 2003 SG4 meeting
General Purpose TMN Paradigm Criteria • Scalability (106 - 107objects) • Compatibility with existing models • Support for multiple managers • Support for query capabilites • Support for data modification capabilities • Support operations on set valued attributes • Support multiple object access • Selective access of attributes • Support operations on multiple objects • Support of autonomous notifications • Well defined notifications • Support for modelling of the containment relationship • Support of unique names • Support of creation and deletion semantics
