Application of X.25 Load Balancing

I. Networking Requirements

Configure hunt group on Server RouterA which serves as an X.25 switch and simultaneously enable the function of substitution of destination address and source address, so that the caller can treat router RouterB, RouterC and RouterE equally as one destination, and the calls of X.25 terminal can be sent to routers RouterB, RouterC and RouterE to achieve load balancing. Therefore the load balancing of routers on X.25 network can be implemented. As an X.25 switching exchange, router RouterD performs the XOT function and connects RouterA and RouterE. Router RouterB, RouterC and RouterE are DTEs in a hunt group. They provide X.25 terminals with identical services.
