Preliminary Study of Open Signalling for ATM Networks

摘要

Based on a clear separation between switching hardware and control software, the concept of open signaling creates an open programmable networking environment. Network entities can be realized as high level objects with well defined software interfaces, facilitating the creation of multiple mechanisms for connection management. Applying open signaling in defense networks can enhance the flexibility in supporting network services, allowing dynamic control of quality of service for maximum military value. This report discusses the design criteria and the associated performance issues of a connection management system for ATM networks. However, significant binding overheads are generated in remote operation invocations, adding a level of complexity to network control. This complexity is expected to diminish as middleware technology matures, thereby improving the overall performance in connection management.
