The advent of packet-switched networks has led to increased use of computers for sending text messages (memos) between people. However, attachment to common carrier or equivalent packet networks is expensive and/or restricted by organizational policies. In addition, use of several networks creates the need for relaying memos between them. The work described(More)
Ethernet is being deployed in metropolitan area networks (MANs) as a lower-cost alternative to SONET-based infrastructures. MANs are usually required to support common communication services, such as voice and frame relay, based on legacy synchronous TDM technology in addition to asynchronous packet data transport. This paper addresses the clock(More)
