An ATM switch control interface for quality of service and reliability

摘要

Traditional communication switches include an embedded processor that implements both the switch control and network signalling. Such an architecture is failure-prone due to the complexity of the control software of mdoern network. Recently, a new approach of controlling siwtches through an external controller is gaining momentum, due th flexibility and reliability it affords. In addition, open control protocols and interfaces for controlling and managing networks, are now emerging as an alternative to specifications and standards. For instance, in the OpeNet project Sun Labs has designed and implemented an open, high performance ATM network control platform.
