    • This invention is to enable inter-domain routing using MPLS. When communication is carried out passing through plural domains, respective management servers managing respective domains cooperate to carry out path constitution and optimum routing. At the path constitution, the respective management servers connect links within the respective controlling domain to constitute paths to reach a target address. When the paths are constituted, label data is notified to nodes associated with the constituted paths, and is used at the routing. At the routing, the management server controlling the source domain obtains the dynamic transmission bandwidths from the respective management servers, and identifies the routing policy from a port number of a request to be routed or the like to identify the optimum path. When the optimum path is determined, it is possible to carry out the routing using the label data held in the respective nodes.
    • 本发明是为了实现使用MPLS的域间路由。 当通过多个域进行通信时,管理各个域的各个管理服务器协作来执行路径构成和最佳路由。 在路径构成中,相应的管理服务器连接各个控制域内的链路,构成路径以达到目标地址。 当构成路径时,将标签数据通知给与构成路径相关联的节点,并在路由中使用。 在路由中,控制源域的管理服务器从相应的管理服务器获得动态传输带宽,并根据要路由的请求的端口号等来识别路由策略,以识别最佳路径。 当确定最佳路径时,可以使用保存在各个节点中的标签数据来执行路由。
