Access relay method and access gateway device
First Claim
1. A network system including a plurality of nodes coupled with each other, one of the plurality of nodes being configured to send to another one of the plurality of the nodes a message prepared according to a protocol processing;
- wherein in case that a destination identification identifier has been set at a head of a datagram including the message that has been received, the one of the plurality of nodes is configured to;
(1) generate another datagram including the message to be sent to one or more nodes, which are designated by a processing of the destination identification identifier; and
(2) send the datagram generated,wherein the destination identification identifier to be referred to is configured to be set by another node different from the one of the plurality of nodes,wherein the destination identification identifier is configured to be set in accordance with a predetermined rule.

Abstract
A gateway device disposed at front stage before a server has a dispersion rule of data dispersed on server side and analyzes communication data to specify a server to be accessed finally, so that identification information of the specified server is added to packet option of IP layer to thereby omit higher-rank routing processing than IP layer of gateway devices on the way. Consequently, transfer processing of a gateway device at back stage can be performed at high speed and access passing through a network route intended by manager is possible.
