11:00 - 12:30 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

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.
