    • A method for message routing in a Peer to Peer (P2P) network includes the following steps: when a request message is routed from a source peer to a destination peer, the source peer and every intermediate peer that needs to be recorded add path information of the local peer to the request message and forward the request message to a next hop until the message arrives at the destination peer, where the path information includes a communication address of the local peer; the destination peer adds the path information in the request message to a response message obtained according to the request message; and the response message is routed from the destination peer to the source peer according to the path information. A source peer, an intermediate forwarding peer, and a destination peer as well as a message routing system are also disclosed. With the present invention, recursive message routing is implemented in a structured P2P network. Because a peer in the P2P network no longer needs to maintain a local transaction table, resources of the peer are saved and the cost of the P2P network is less.
    • 对等(P2P)网络中的消息路由方法包括以下步骤:当请求消息从源对等体路由到目的端对等体时,需要记录的源对等体和每个中间对等体将路径信息添加到 本地对等体到请求消息,并将请求消息转发到下一跳,直到消息到达目的地对等体,其中路径信息包括本地对等体的通信地址; 目的地对等体将请求消息中的路径信息添加到根据请求消息获得的响应消息; 并且响应消息根据路径信息从目的地对等体路由到源对等体。 还公开了源对等体,中间转发对等体,目的地对等体以及消息路由系统。 利用本发明,在结构化P2P网络中实现递归消息路由。 由于P2P网络中的对等体不再需要维护本地事务表,因此保存对等体资源,P2P网络成本较低。

    • A method for transferring test messages includes a Network Element (NE) A and NE B negotiating and determining a logical channel type. The Link Management Protocol (LMP) entity of NE A constructs a test message packet which includes the local Ethernet data interface ID, and transfers the test message packet to the local packet control module. The packet control module of NE A encapsulates the test message packet according to the logical channel type determined through negotiation, and transfers the encapsulated packet to the local transmitting interface. The receiving interface of NE B identifies and receives the packet. The packet control module of NE B obtains the packet from the local receiving interface and then encapsulates the packet. Next the packet control module of NE B transfers the test message packet obtained after decapsulation to the local LMP entity. Therefore, the test message can be transferred on the Ethernet data interface, and the auto discovery of the Ethernet physical link of the NE device succeeds once the test message is transferred successfully.
    • 用于传送测试消息的方法包括协商和确定逻辑信道类型的网元(NE)A和NE B。 NE A的链路管理协议(LMP)实体构建包含本地以太网数据接口ID的测试报文,并将测试报文分组传送给本地报文控制模块。 网元A的报文控制模块根据通过协商确定的逻辑信道类型封装测试报文报文,并将封装报文传送到本地发送接口。 NE B的接收接口识别并接收报文。 NE B的报文控制模块从本地接收接口获取报文,封装报文。 接下来,NE B的分组控制模块将解封装后获取的测试消息包传送到本地LMP实体。 因此,可以在以太网数据接口上传输测试消息,一旦测试报文成功传输,网元设备的以太网物理链路自动发现就会成功。
