Abstract
This invention provides an improved data transferring menthol performed in a communication network comprising a management system M1 and a plurality of nodes. Since the management system M1 collectively manages the algorithm information that indicates algorithm possessed in each node, if the fist node does not have algorithm needed for processing a certain packet, the first node can find the second node with the algorithm by requesting the network management unit M1 to send protocol information. In addition, the first node can transfer the certain packet to the second node to process the certain packet by using the algorithm.
Claims15
A data transferring method performed in a communication network comprising a management system and a plurality of nodes, the method comprising steps of;
- storing protocol information in the management system, the protocol information indicating transferring functions operable by each of the plurality of the nodes,
- receiving, at a first node, a packet having a destination address,
- detecting, at the first node, a transferring function needed for transferring the packet,
- requesting the management system to send the first node a second node information regarding a second node having the transferring function if the transferring function is not stored in the first node,
- sending the second node information from the management system to the first node,
- sending the packet from the first node to the second node to perform the transferring function for the packet, according to the second node information,
- returning the packet from the second node to the first node, and
- transferring the packet to the destination address.
A communication network system comprising a management system and a plurality of nodes, wherein the management system comprises;
- an algorithm management unit for storing protocol information that indicates a transferring function possessed by each of the plurality of nodes, and
- a network management unit for communicating with the plurality of nodes and for providing node information that indicates a node having a transferring function based on the protocol information, and
- a first nodes comprises;
- a detecting unit for detecting a required transferring function needed for transferring a received packet having a destination address,
- a requesting unit for sending a request signal to the network management unit to obtain a second node information indicating a second node having the required transferring function when the first node is not provided with the required transferring function, and
- a transferring unit for transmitting the received packet to the second node according the second node information to perform the required transferring function for the received packet and for transferring the received packet to the destination address after receiving the received packet from the second node.
A node in a communication network system, the node comprising;
- a receiving means for receiving a packet,
- an algorithm detecting means for detecting a required transferring function needed for transferring the packet,
- an requesting means for requesting a management system, which stores protocol information indicating a transferring function possessed by each of the plurality of nodes, to send the node a second node information regarding a second node having the required transferring function if the required transferring function is not stored in the node;
- an requesting means for requesting the management system to obtain the second node information, and
- a transmitting means for transmitting the packet to the second node based on the second node information,
- wherein the node receives, from the second node, a performed packet that the required transferring function is performed by the second node and transfers the performed packet to a destination address.
