Embodiment Construction

[0021] The active network technology described above is particularly suitable for Internet type networks, ie networks based on Internet Protocol (IP) type communication protocols. In the above environment a node is called a router and an active node is called an active router.

[0022] In an Internet-type network environment, routing protocols largely conform to the Open Shortest Path First (OSPF) standard described in RFC 2328 of the Internet Engineering Task Force (IETF).

[0023] According to the standard, routers periodically inform each other of their status by exchanging OSPF messages, which can contain different types of messages indicated by the value of a "type" field, including "call" messages and "link state update" messages.

[0024] The purpose of the "Hello" message is to inform its neighbors of the status of a router. "Hello" messages are sent at regular intervals so that when a router does not receive a "Hello" message from another router for a substantial tim...

Abstract

Method to advise on the capacity of a node to process messages in a specific way. The node in question sends routing messages periodically to neighbouring nodes. There is a stage in which information relating to the process is inserted in the routing messages.

Description

technical field [0001] The invention relates to a telecommunications network whose nodes can receive information messages and process the messages in a specific way. Background technique [0002] The invention is particularly applicable to active networks. DARPA proposed the concept of active network in 1994 and active network became the theme of the first international conference IWAN 99 (International Symposium on Active Network). [0003] An active network in this context is a network whose nodes, or certain nodes, are able to process messages transmitted by the network in a specific way. In other words, these nodes must be able to implement an algorithm that is different from those designed into the nodes. [0004] Within an active network, it is not necessary to provide this processing capability to all nodes: thus a distinction is made between active and non-active (ie normal) nodes. [0005] An active node can perform various processing: [0006] It can execute th...
