Carrier Ethernet transport in metro and core networks

Abstract

Presents a 130-slide tutorial on Carrier Ethernet Transport (CET). CET is not a single technology but a multilayer network architecture. It enables predictable packet transport networks and combines flexible electronic packet layer with cost-efficient optical layer. CET provides efficient multilayer traffic engineering (IP, Ethernet, NG-SDH/SONET, OTH/WDM)along with eEfficient end-to-end Quality of Service (QoS) and resilience and native transport of layer 2 services. CET's main forwarding technologies are: MPLS-TP, PBB-TE, ELS. The tutorial covers: Operator Requirements for Transport Networks; Ethernet Basics; Carrier Ethernet Evolution; Carrier Ethernet Transport Technologies; Carrier Ethernet Transport Network Architecture & Solutions; and Outlook Towards Future Internet Architectures.
