Abstract
A network system comprises a plurality of network segments. Each of the network segments connects a plurality of user terminals that can be set in a suspend mode. When a network segment is connected to the network system via a router, it is possible that the network address of a user terminal is deleted from the routing table in the router during an aging process. In this situation, the user terminal is not accessible in the suspend mode via the router. To solve this problem, a proxy terminal is connected to a network segment to receive requests from the router for the user terminals connected to that network segment. In response to a request from the router to a destined user terminal located in that network segment, the proxy terminal wakes up the destined user terminal, thus restoring the access to the destined user terminal.
