Abstract

[Technical Problem] The communication destination is fixed and cannot be arbitrarily selected. [Solution to Problem] A control apparatus for controlling a network includes: path control means for using the communication apparatus based on a group of communication apparatuses connected to the network and including communication apparatuses all having the same identifier and using the an identifier as a destination address to perform communication between source communication devices, selecting a communication device having the identifier from the communication device group as a destination communication device, and sending a communication device to a transmission device in the network Processing corresponding to the path from the source communication device to the selected destination communication device is set.

Description

technical field [0001] The present invention relates to a control device, a communication system, a communication method, and a recording medium on which a communication program is recorded in a network for performing communication. Background technique [0002] In recent years, a large number of technologies have been developed in which various services are provided by servers in response to communications from clients (users). [0003] In a system that provides services to clients, load balancing, scalability, etc. need to be considered. In order to preserve such load balancing and scalability, there is a technique of commonly using a single identifier (such as an IP (Internet Protocol) address, etc.) among a plurality of servers. As an example thereof, Patent Document 1 is mentioned. [0004] According to the technique disclosed in Patent Document 1, a relay device in a network manages a table in which an IP address of an information processing device as a transmission ...
