Problems solved by technology

[0010] A practical limitation of the parallel load balancing node structure shown in Figure 1 is that such a structure cannot function as a transparent bridge, but must act as a router

Embodiment Construction

[0023] The principle and operation of the network load balancing structure according to the present invention can be understood with reference to the drawings and accompanying descriptions.

[0024] serial structure

[0025] figure 2 A non-limiting example of a network load balancing structure according to an embodiment of the present invention is illustrated. Clients 101a, 101b, 101c, and 101d are ultimately connected to wide area network 111 through firewall 109, as in a typical prior art architecture (FIG. 1). However, only a single switch 203 is required since nodes 205a, 205b, 205c and 205d are connected in series rather than in parallel as in prior art nodes 105a, 105b, 105c and 105d (FIG. 1). The term "cluster" here means a plurality of network devices interconnected to achieve a unified goal. The structure of the prior art and the structure of the present invention are collectively referred to as a cluster.

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 node.

Description

technical field [0001] The present invention relates to data network load balancing, and more particularly, to load balancing of network nodes such as servers and gateways. Background technique [0002] In many network implementations, nodes such as servers and gateways are clustered in parallel in a redundant structure to provide higher availability and reliability, and by distributing the workload among a group of nodes according to the criteria of optimizing the overall data throughput To prevent data traffic congestion. [0003] The term "node" here means any point within a network where data processing may be performed, including but not limited to: servers, gateways, and similar devices. [0004] The term "load balancing" herein means distributing data processing load among a group of nodes for the purposes of, but not limited to: preventing data traffic congestion; reducing processing latency; increasing processing availability; and increasing processing reliability....
