Embodiment Construction

[0020] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0021] Such as figure 2 As shown, it is a schematic diagram of embodiment one of the message header format of the RUDP message of the present invention; this embodiment adds a fault location field before the CheckSum field of the message header of the RUDP message, and its size can be selected according to specific applications, such as 4 bytes or 2 bytes; the fault location field is used to carry fault location parameters, such as the time when the source node sends the RUDP message or the address of the node; in addition, when the fault location para...

Abstract

The invention discloses a location method and device for failures of a reliable user datagram protocol (RUDP) link, The location method includes the following steps: S1, failure location fields are added in a message header of an RUDP message in advance; S2, failure location parameters are filled in the failure location fields of the RUDP message and the message is sent to a next skip node when a source node sends data to a destination node; S3, the source node locates the failure points according to preset strategies when the transmission path fails. The location device for failures of the RUDP link comprises a RUDP message management module and a failure locating module. The location method and device for failures of the RUDP link is capable of reducing out-sending data and relieving network load.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a RUDP (Reliable User Datagram Protocol, Reliable User Datagram Protocol) link fault location method and device. Background technique [0002] RUDP is a simple packet transport protocol based on RFC908 and 1151 (Second Edition). RUDP provides a message-based reliable communication function, the communication is connection-oriented, and the underlying layer uses UDP as the bearer protocol. As a reliable transmission protocol, RUDP is used to transmit telephone signals between IP networks. An important function of RUDP is retransmission. When sending a message, a timeout timer will be started. When the timeout timer expires and no response from the peer end is received, the message will be resent. This mechanism effectively guarantees data reach the peer. figure 1 It is a schematic diagram of the RUDP packet format in the protocol. Among them, the SYN field indicat...
