Abstract
A method and system are provided for operating a transmission system having connected nodes. Channels are assigned for carrying traffic along the connections according to a multiple protection classes. Traffic may then be propagated over the connections in accordance with the assigned protection classes.
Claims36
A method for operating a transmission system that uses a defined multiplexing scheme and has a plurality of connected nodes, the method including:
- assigning channels for carrying traffic along connections between the nodes according to a plurality of protection classes.
A ring transmission system comprising:
- a plurality of nodes configured as a ring and connected by connections in opposite directions around the ring;
- and
- a manager coupled with the plurality of nodes, the manager being configured to assign channels for carrying traffic along the connections according to a plurality of protection classes.
A system for operating a ring transmission system having a plurality of nodes configured as a ring connected by connections in opposite directions around the ring, the system comprising:
- a manager configured to assign channels for carrying traffic along the connections according to a plurality of protection classes;
- and
- a controller coupled with the manager and the ring, wherein the controller is configured to propagate signals along traffic paths within the ring in accordance with the assigned channels and protection classes.
A system for operating a ring transmission system having a plurality of nodes configured as a ring connected by connections in opposite directions around the ring, the system comprising:
- means for assigning channels for carrying traffic along the connections according to a plurality of protection classes;
- and
- means for propagating signals along traffic paths within the ring in accordance with the assigned channels and protection classes.
