1. A method for enabling sessions established between a client and a server to be uniquely defined to enhance the performance of a load balancing system, the method comprising the steps of:

  • receiving a packet from a client connected to a network, the packet including a sender session identifier;

    parsing the packet to obtain the sender session identifier;

    hashing over at least the sender session identifier to determine which node within the load balancing system will acquire the packet; and

    acquiring the packet by a single determinant node based on the results of the hashing step.
