Title:
マルチキャスト配信制御方法、および、配信ルータ
Document Type and Number:
Japanese Patent JP5758858
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To achieve high load distribution with an interface group in such configuration that the interfaces of a plurality of multicast distribution routers are connected to a shared segment.SOLUTION: A distribution router 4 executes first association processing of calculating a flow hash value for each flow to be distributed via a shared segment 5, and associating each flow pertinent to the flow hash value included in the area in charge of each of virtual IF arranged with equal intervals in a hash space with the virtual IF and second association processing of associating a virtual IF group constituted of one or more virtual IF with the actual IF of the distribution router 4, and controls each flow to be distributed by each specified actual IF.
