Abstract
An object of this invention is to reduce a calculation amount and required storage capacity of a URL switch by dividing transfer destination determining processing among a plurality of devices. Provided is a computer system including: a plurality of servers; and a packet transfer device, in which: the servers are coupled to the packet transfer device; the packet transfer device is coupled to a client terminal via a network; the packet transfer device receives a content request including a fixed-length hash value that is calculated from a variable-length identifier of the content requested by the client terminal; extracts the hash value from the received content request; and determines, based on the extracted hash value, to which one of the plurality of servers the content request is to be transferred.
