摘要:
A call setup and restoration schema is disclosed for providing an improved priority-based call setup and restoration schema in an optical communications system, allowing higher priority connections access to bandwidth by user-definable parameters. The call setup and restoration schema includes allowing higher priority connections to claim the resources of lower priority connections, and restoring them when bandwidth is available, or bumping another, even lower priority, connections. This aids in providing access to bandwidth by high priority services and in preventing outages or connection delays for high priority connections.
