Abstract: Provided herein is a method for realizing time reduction in shared mesh protection, the method including, in a protection path node, in response to a resource being used for a first protection path by a node, receiving a resource use request for setting a second protection path from another node; activating a protection switch through comparison of priorities of protection paths at the resource use request received; and transmitting, by the activation of a protection switch, to a next protection path node a first shared mesh protection message where a revert (RT) message for the first protection path and a protection switch (SF) message for setting a second protection path are multiplexed.

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.
