SOURCE ROUTING METHOD FOR FAST CONNECTION RE-ESTABLISHMENT IN RESPONSE TO EARLY-ARRIVING TROUBLE REPORT MESSAGES |
摘要 |
<p>In a connection-oriented network, a route table and a network resource table are provided in a source node which updates the network resource table in response to a topology state message which is flooded through the network whenever there is a change in the available network resources. The source node updates the network resource table in response to an early-arriving trouble report message from the network if such a change in the available network resources occurs when a connection is being progressively established or already established from the source node. In response to a connection setup message, the source node fetches a route from the route table and compares a user's requirement such as quality and/or bandwidth with the resource data of the fetched route stored in the network resource table. A connection is established via the fetched route if the resource data of the fetched route in the network resource table indicates that the fetched route can support the requirement.</p> |
