Problems solved by technology
[0011] The inventor believes that this method has at least the following problems: when using this method, due to the limited capacity of the transaction record table, the transactions that the peer can maintain within a certain period of time are limited. If the transaction record table is full, new requests will be rejected unconditionally

Embodiment Construction
[0047] The implementation of the present invention will be further described below in conjunction with the drawings and examples.
[0048] In Embodiment 1 of the present invention, a message routing method such as Figure 5 shown, including the following steps:
[0049] Step s501. During the process of routing the request message from the source node to the destination node, the source node and each intermediate node that needs to be recorded add the path information of the node in the request message, and send it to the next hop node until reaching the destination node .
[0050] Through this record, the necessary path information passed in the message routing is stored in the request message, so that each node does not need to record the message it has forwarded on its own device. Specifically, the location where the record is saved can be located in the header of the request message, specifically: add a path field in the header, and the path field stores the communication...

The invention discloses a message routing method in a peer-to-peer network, comprising the following steps: when a request message is transmitted from a source node route to a destination node, a source node and every intermediate node to be recorded add path information of the nodes in the request message, and transmit the path information to a next hop node till reaching the destination node; the path information comprises the communication address and cross identification of the nodes; the destination node adds path information in the request message to a response message acquired according to the request message; and the response message is transmitted from the destination node to the source node according to the path information. The invention also discloses a source node, an intermediate forward node, destination node equipment and a message routing system. The message routing method realizes message recursion routing in a structured peer-to-peer network, and ensures that nodes in the peer-to-peer network do not need to maintain a transaction record table locally, thereby saving resources of each node and reducing overhead of the peer-to-peer network.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to a message routing method, system and node equipment in a structured peer-to-peer network. Background technique [0002] The P2P (Peer to Peer, peer-to-peer network) technology makes full use of the capabilities of each node in the system to provide services to each other. The use of P2P technology will greatly increase the utilization of these nodes, thereby further improving the performance of networks, equipment and information services. P2P systems further include structured, unstructured and loosely structured systems. Among them, the characteristic of the structured P2P system is that the release of resources is closely related to the network topology, and the resources are accurately distributed in the network according to the logical addresses in the P2P topology. Each node in this type of system has a virtual logical address, and all nodes form a relatively stabl...
