ABSTRACT:
A method and system for maintaining a connection between two hosts in a multi-hop network comprising at least one network node disposed between the two hosts and a network element, e.g., a NAT, designed to release the connection after a period of inactivity. The method includes determining a first node in which a keep-alive message will terminate after crossing a network element designed to release the connection after a period of inactivity, and sending a keep-alive data packet configured to terminate in the first node after crossing the network element designed to release the connection. The keep-alive packet configured to terminate in the first node after crossing the network element designed to release the connection may be sent within a time period less than the time period of inactivity after which the network element would release the connection. The method allows for a connection to be kept open without waking up a client device and/or without activating air interface procedures.
