Abstract
According to various aspects of the present invention, a technique is described for improving load balancing of traffic in a data network using source-side related information embedded into the destination IP address field of packets received at a load balancing device. One aspect of the present invention relates to assigning more than one virtual IP address to a server cluster in order to enable different clients to select a virtual cluster address which corresponds to each clients' respective rights and/or profiles, and to use the selected virtual cluster address to access a desired site or service. Another aspect of the present invention relates to a mechanism which allows for load balancing operations to be implemented using source-side information which is embedded into the destination IP address of a packet header. In this way, load balancing decisions may be quickly performed at initial or early stages of a connection flow.
