ROUTING METHOD BETWEEN DOMAINS FOR A CONTENTS CORE NETWORK CAPABLE OF LINEARLY INCREASING A SIZE OF ROUTING TABLE ACCORDING TO INCREASE OF THE NUMBER OF GROUPS AND CONTENTS CORE NETWORK THEREOF

摘要

PURPOSE: Routing method between domains for a contents core network and contents core network thereof are provided to configure a group based on a relationship between domains and to limit control traffic for routing and entry of a routing table within a group.;CONSTITUTION: An identification unit (810) identifies a path to at least one hub in a first domain from an anchor hub within the first domain. The anchor hub stores routing information in between a first border hub in the first domain and a second border hub in a second domain. A detection unit (820) makes at least one hub in the first domain detect a neighboring hub with sink operation based on a sink direction corresponding to the identified path. At least one hub in the first domains performs the sink operation with the neighboring hub, a sharing unit (830) shares the routing information stored in the neighboring hub.;COPYRIGHT KIPO 2013;[Reference numerals] (810) Identification unit; (820) Detection unit; (830) Sharing unit; (840) Updating unit
