Ethernet Protection

This session will review the protection mechanisms under study within ITU-T and IEEE 802 for Ethernet bridging standards. The session will commence with an overview of the IEEE 802.1AX LAG revision that includes DRNI.  It will then review the new work on seamless redundancy as well as path control and reservation.  The session will continue with ITU-T overviewing applications for G.8032 Ethernet ring protection.  This will be followed by a review of new work on protection interworking for Ethernet & OTN and multipoint Ethernet protection.

Packet Synchronization - Introduction

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 synchronization and low latency requirements. This session will describe these new requirements, and the resource management, time synchronization mechanisms and protocols being standardized to achieve them. The first part of this session will focus on providing an overview of three key time synchronization standards, notably precision time synchronization (IEEE 1588, IEEE 802.1AS) and the telecom profile for time synchronization (ITU-T G.827x).

​14:00 – 16:00​

Packet Synchronization - issues

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 synchronization and low latency requirements. This session will describe these new requirements, and the resource management, time synchronization mechanisms and protocols being standardized to achieve them. The second part will focus on key issues that are being discussed in the context of standardizing time synchronization. In addition, new projects on improving the latency performance of Ethernet to support time sensitive traffic will be described, e.g. scheduled traffic & frame preemption (IEEE 802.1Q) and minimum latency traffic (IEEE 802.3). Ongoing standardization efforts and unfulfilled standardization needs will be explored.
