1. A method of operating a server computer for controlling data traffic of a computer network, the method comprising:

  • receiving network data traffic through a network interface that permits communication between the server computer and other computers;

    communicating with a plurality of server computers that are all members of a first subnet of network addresses over which network data is sent and received, comprising a front layer of servers, wherein the communication includes state sharing information with a dynamic reconfiguration protocol that permits reassignment of network addresses among the front layer servers and specifies state information sharing and load information sharing among the front layer servers;

    communicating with a plurality of network computers that are members of a second subnet of network addresses to send and receive network data traffic;

    determining if the data traffic is associated with a previous network communication session of an original server computer of the first subnet, prior to a network address reassignment for the original server computer;

    responding to data traffic not associated with a previous network communication session of an original server computer by processing the data traffic; and

    responding to data traffic that is associated with a previous network communication session with an original server computer by checking a record of network address assignments and identifying the original server computer associated with the previous network communication session and forwarding the data traffic to the identified original server computer.
