Abstract:
1. A gateway system to distribute requests from multiple terminals to multiple first server devices, comprising: a plurality of second server devices; a name resolution device that generates an IP address from a character string; and a management device, wherein address generating functions, which are hash functions that generate a hash value from the character string, generate the IP address from the character string are distributed to the name resolution device, wherein a plurality of specified IP addresses are registered in each of the second server devices, wherein, when a first request for resolving a name of an access destination URL is received, the name resolution device: extracts the access destination URL from the received first request, generates the IP address from the character string of a host name of the extracted URL by utilizing the hash functions, and sends the generated IP address to a terminal as a reply to the first request, and wherein, when the terminal sends a second request setting the access destination of the URL for one of the first server devices to one of the second server devices where the IP address sent as a reply to the first request is registered, the one second server device transfers the second request to the one first server device based on the access destination URL, wherein the management device: distributes the address generating functions to the name resolution device, divides all IP addresses generated by the name resolution device into a plurality of IP addresses, and distributes the plurality of IP addresses to each of the second server devices, and wherein the second server devices register the plurality of distributed IP addresses.
