IPv6 anycast routing for the continuity of a service flow

The anycast service makes Load-balancing since providing the connection of the nearest server for a user. The anycast service improves the server bandwidth and improves the quality of a service. And the anycast service maintains the continuity of a service in a failure and can prevent a damage including a stability and DoS attack of a server, and etc. Owing to this advantage, in the Internet environment, the demand which applies the anycast service as a service becomes gradually various is more generated. However the feature of the anycast service is suitable for the application which uses the UDP protocol since the server communicating not being always fixed and guaranteeing the continuity of a service. Therefore, in this paper, we propose the anycast servicing scheme guaranteeing the continuity of a service. The proposed IPv6 anycast service is used with the unicast routing and like that can use the legacy router.
