Abstract:
A method and apparatus for mitigating traffic increase due to both a proxy server and a network device transmitting response packets to a search request by multicast. The network device transmits to the proxy server information required for a client apparatus to communicate with the network device. When the proxy server is in a state where proxy-send of the information is possible, the network device restricts response to a search request by multicast from the client apparatus.
