The present invention provides a method, system and apparatus by which TCP connections may be failed-over from one system to another within a highly available network service, and appear transparent to the remote client. The connection state and ownership information of a system is broadcast within the network, so that if a first system crashes while running an application, a predetermined take-over policy causes a peer system to assume connection without loss of data such that a permanent connection has been established from the client's point of view. After the failed system has been restored to a normal state, new connections are established by the first system. A connection cache device stores connection information for use during the failover.
