Method for direct access to information stored in nodes of a packet switching network

摘要

Method for direct access to information stored in the nodes of a packet switching network comprises the steps of: collecting the pointers, corresponding to which the information required for processing the packets belonging to one and the same flow is stored in each node of the network;—constructing a distributed linked data structure (DLDS) in which the pointers are contained inside packets (PI, P2, P3) that traverse the DLDS-aware routers constituting the path between sender (A) and receiver (B) of the flow;—use of the DLDS data structure for direct access to the information stored in a DLDS-aware router, using a pointer of the DLDS contained in the packet in transit;—selection of the pointer of the DLDS contained in the packet in transit based on its position inside said packet, said position being equal to the serial number of the DLDS-aware router in the flow path, and checking of validity by consistency tests.

1. A method for direct access to information stored in nodes of a packet switching network, wherein said method comprises the steps of:
collecting pointers to memory locations at which information necessary for processing packets belonging to a same flow is stored in each node of the network; constructing a distributed linked data structure (DLDS) in which the pointers are contained inside packets that traverse nodes constituting a flow path between a sender node and a receiver node; using said DLDS for direct access to the information stored in a node in the flow path, using a pointer of the DLDS contained in a packet in transit; and selecting the pointer of the DLDS contained in the packet in transit based on a position of the pointer in a sequence contained in said packet, said position being equal to a serial number of the node in the flow path.
