Abstract: A protection switching management apparatus and method for effective use of resources in a multilayer or a multi-domain. The protection switching management method may include receiving an adaptation request from a network component included in an upper layer, determining whether to apply protection switching to a layer based on the received adaptation request, and setting a protection path in the layer based on a result of the determining.

Abstract: Provided is a linear protection switching method of a node, wherein the method includes selecting a local request based on a priority of at least one local request, determining a global request based on a priority between the selected local request and a remote message, and performing a state transition based on the global request.

Abstract: A parallel scheduling apparatus includes an information managing unit generating a first request information for scheduling, a first scheduling unit performing first scheduling and then generating first matching information on the basis of the first request information, and a second scheduling unit performing second scheduling on the basis of the first request information and the first matching information. The parallel scheduling has an advantage of improving the scheduling performance and lowering the implementation complexity, ensuring low delay and transmission fairness among VOQs at low input traffic, being applied to all scheduling algorithms that perform existing multi-iterations, and providing efficient scheduling in a packet switch having a long RTT time or having a very short time slot or cell size, such as an optical switch.
