Abstract: A method for discriminating a transmission path in a router system is provided to perform efficient load balancing in the multicast method, and immediately cope with congestion which is occurring in a specific port of the router system. A method for discriminating a transmission path in a router system comprises the following steps of: searching the address corresponding to the destination address by referring to a forwarding table(S210); determining whether the corresponding address is the absolute address or the relative address; determining the transmission path according to the absolute address registered in the forwarding table; and searching the address corresponding to the relative address registered in the forwarding table from an opposite side forwarding table(S420).

Abstract: PURPOSE: A relay server of inter-hetero networks is provided to surmount a speed difference between a high speed network and a low speed network by the relay server. Therefore, it is possible to supply sufficient video information to a user in real time. CONSTITUTION: If a selection item is received after receiving a service retrieval request from a user, a service retriever(202) transmits a server address, a service form and the selection item, and receives a decided result for a relay function. The service retriever(202) is directly connected with a high speed network server to supply a service when the selection item is in the high speed network capable of performing a real time service. A real time controller(203) receives the server address, the service form and the selection item from the service retriever(202), and decides whether the relay function is necessary. If not, the real time controller(203) transmits a decided result to the service retriever(202). If the relay function is necessary, the real time controller(203) measures a traffic by connecting with a server(204) to decide a buffer size, and requests data to the server(204) to transceive the data. When minimum data is received from the real time controller(203), a stream controller(205) uses a stream protocol to transmit the data to the user.
