Multimedia Communications eXchange (MMCX) local and wide area network considerations

Abstract

The Multimedia Communications eXchange (MMCX) product provides multimedia (voice, video and data) desktop collaboration. The MMCX client/server architecture supports multimedia calling between endpoints on the local area network, and also provides access to the wide area network. The MMCX endpoints can make multimedia calls across the WAN in multiserver networks, and can place audio calls to traditional voice endpoints, for example, telephones connected to PBXs and the public switched telephone network. This paper describes the LAN and WAN technologies and protocols supported by Release 1 of the MMCX product. It also covers the performance characteristics (delay and bandwidth requirements) of each media (voice, video and data) and well as the bandwidth management capabilities of the MMCX client/server architecture.
