This document summarizes a Cisco Knowledge Network presentation on the network after SONET. It introduces the speakers and topic, which is how networks have evolved beyond the traditional SONET architecture. The presentation traces the history of network technologies from 2000 to 2002, starting with SONET and the introduction of Ethernet. It notes the challenges that arose with mapping Ethernet to SONET, such as rigid mapping and inefficient use of bandwidth. The presentation aims to explore new network architectures to address these challenges.
