Session 3: Ethernet Bridging Architecture
Session moderators: Glenn Parsons (ITU-T Study Group 15 representative to IEEE802.3)
and
Mick Seaman (Independent, USA )
Session Objectives:
This session will review the architectures used within ITU-T and IEEE 802 that are used in the development of Carrier Ethernet bridging standards. The session will commence with an overview of the ITU-T and IEEE architectural modelling philosophy. What are the principal concerns that drove the architecture, what are the aspects of the architecture that are regarded as being particularly important to the success of the technology. It will then review the application of this modelling to the design of bridging protocols within Ethernet standards in IEEE 802 and ITU-T.
Standards areas covered will include:
IEEE 802.1 architectural goals and guiding principles from enterprise to carrier networks
ITU-T functional modelling evolution (G.805/G.809/G.ufatn) from circuit (e.g., SDH) to packet (e.g., Ethernet) networks
IEEE 802.1 bridging architecture for Carrier Ethernet from D & Q bridges to PB, PBB & PBB-TE
ITU-T G.8010 Ethernet bridging architecture allowing ITU understanding (and management) of IEEE Ethernet bridging

John Messenger (ADVA Optical Networking Ltd)
Session Objectives:
This session presents current status and overview of standardization on OAM, protection switching and restoration functions including network management functions and NMS/OSS aspects. Through presentation and discussion, participants identify issues to be studied and standardized through collaboration of IEEE and ITU-T.
Standards areas covered will include:
IEEE802.1ag (Connectivity Fault Management), ITU-T Recommendation Y.1731 (OAM functions and mechanisms for Ethernet based networks), architectural goals and guiding principles from enterprise to carrier networks, and the future study items
Restoration technologies (e.g., xSTP, IEEE 802.1aq), and the future study items
ITU-T Recommendation G.8031 (Ethernet linear protection switching), G.8032 (Ethernet ring protection switching), and the future study items

Session 5: Ethernet QoS, Timing, and Synchronization
Session moderators: Neal Seitz (ITU-T Study Group 13 WP4 Chair)
and
Pat Thaler (IEEE)
Session Objectives:
Deployment of Ethernet facilities and services in carrier-class access, metro, and core networks will require enhancement of existing packet-based Ethernet technologies to support QoS control and synchronization requirements. This session will describe these new requirements, and the resource management, time distribution, and frequency synchronization mechanisms and protocols being standardized to achieve them. Panellists will identify applications with particularly demanding QoS requirements (e.g., VoIP, IPTV, VTC, real-time multi-party gaming, grid computing); describe carrier functions and services requiring precise time and frequency synchronization (e.g., performance monitoring and accounting, PDH and SDH transport); and summarize the relevant numerical performance objectives. Standardized Ethernet QoS, time distribution, and frequency synchronization mechanisms and protocols will be described, e.g., priority queuing, flow metering and policing (IEEE 802.1Q), congestion notification (IEEE 802.1au), drop precedence (802.1ad), precision time synchronization (IEEE 1588, IEEE 802.1AS), and packet network frequency synchronization (ITU-T G.8261). Ongoing standardization efforts and unfulfilled standardization needs will be explored.
