Abstract
A load balancer for a network processor has load balance control units that are multistage-connected in series with each other. When distribution destinations of input information concentrates into a specific network processor by distribution process executed by a load balance control unit, the load balance control unit of next stage execute the distribution process about the input information distributed to the specific network processor.
Claims9
A load balancer for a network processor comprising:
- a plurality of load balance control units arranged in a communication device including receiving means and a plurality of network processors for performing processes for input information received by the receiving means, wherein
- the plurality of load balance control units are multistage-interconnected in series with each other,
- each of the load balance control units receives the input information from the receiving means and executes distribution processes for distributing the input information to one of the network processors according to a predetermined distribution condition per input information, and
- each of the load balance control units of the second and subsequent stages supervises a distribution process executed by the load balance control unit of the previous stage, and distributes, when distribution destinations of the input information by the load balance control unit of the previous stage concentrates into a specific network processor, the input information distributed to the specific network processor by the load balance control unit of the previous stage to alternative network processor according to a distribution condition different from the distribution condition used in the load balance control unit of the previous stage.

A communication device comprising:
- receiving means;
- a plurality of network processors for performing processes for input information received by the receiving means;
- and
- a plurality of load balancers, wherein
- each of load balancers includes a plurality of load balance control units that are multistage-interconnected in series with each other,
- each of the load balance control units receives the input information from the receiving means and executes distribution processes for distributing the input information to one of the network processors according to a predetermined distribution condition per input information,
- each of the load balance control units of the second and subsequent stages supervises a distribution process executed by the load balance control unit of the previous stage, and distributes, when distribution destinations of the input information by the load balance control unit of the previous stage concentrates into a specific network processor, the input information distributed to the specific network processor by the load balance control unit of the previous stage to alternative network processor according to a distribution condition different from the distribution condition used in the load balance control unit of the previous stage, and
- when one of the load balancers is used as an active-system and the other load balancers serve as standby-systems, distribution conditions which are being used in the plurality of load balance control units included in the load balancer serving as the active-system are set in the load balance control units included in the load balancers serving as the standby-systems.
