ABSTRACT:
Associated with an optical transport system, a packet oriented supervisory network provides differentiated classes of service (CoS) for a plurality of WDM layer applications on diverse nodes such that as soon as a higher priority application or packet arrives, the lower priority application is affected in favor of the higher one. One or more optical control channels (OSC) are used as the physical medium for implementing the packet oriented supervisory network of the invention. This new functionality of the optical control channel (OSC) enables multiple services by allowing each application to use up to 100% of the OSC bandwidth, if no other application is using it.
