通信システム、転送ノード、経路管理サーバおよび通信方法

Document Type and Number:

Japanese Patent JP5699939

Kind Code:

B2

Abstract:

A communication system comprises: a path management server that generates a plurality of forwarding path information items each includes a sequence of identifiers, each of which identifies a communication interface provided in each of a plurality of forwarding nodes on a forwarding path in a data forwarding network or a link established between the forwarding node and a neighboring node thereof; and a forwarding node that, in accordance with at least one of the plurality of forwarding path information items, executes a packet forwarding processing of a packet with a header including the plurality of forwarding path information items. The communication system that can be implemented using a simplified forwarding table, and moreover can be applied to path control (including an alternative path) of data packets.
