Abstract
A network load-balancing cluster configured to function as a transparent bridge, by connecting the load-balancing nodes in series rather than in parallel, as is done in prior-art configurations. A load-balancing algorithm and method are disclosed, by which each node in the configuration independently determines whether to process a data packet or pass the data packet along for processing by another node. To support this, load-balancing nodes are equipped with both software and hardware data pass-through capabilities that allow the nodes to pass along data packets that are processed by a different nodes.
Claims24
A load-balancing cluster for a data network comprising a plurality of load-balancing nodes connected in series, wherein each of said load-balancing nodes includes:
- A first external data port for receiving a data packet;
- A second external data port for retransmitting said data packet;
- a data handler for processing said data packet;
- and
- a load balancer for determining whether to process said data packet by said data handler.
