Embodiment Construction

[0022] In view of the solution in the related art to prevent data from being sent repeatedly, the data needs to be cached, which affects the data sending speed and requires high equipment requirements. The embodiment of the present invention provides a data sending method and device, which can be sent in the same route In the domain (the network adopts the same routing metric algorithm), when there is a routing loop in the network, control signaling can not be introduced, and data caching and comparison can not be performed. By carrying existing routing exchange information in the data, the data can be prevented. The destination to be sent cyclically. The present invention will be described in further 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.

[0023] This embodiment provides a data sending m...

Abstract

The invention discloses a data sending method and device. Among them, the method includes: after receiving the data, obtaining the routing exchange information of the data; addressing to the local according to the destination address of the data, obtaining the local routing switching information of the data; according to the above routing switching information and the above local routing switching information , to judge whether the above data meets the sending condition; if so, send the data; otherwise, discard the data. The present invention solves the problem in the related art that the solution for preventing data from being forwarded repeatedly is poor in processing effect when a routing loop occurs in the network. The solution is simple to implement and does not need to cache and compare the data during the control process. There is also no additional control signaling, which reduces the probability of data being sent cyclically. There is no special requirement for equipment hardware during deployment, which can fully guarantee the investment of existing equipment and reduce waste of resources.

Description

technical field [0001] The invention relates to the communication field, in particular to a data sending method and device. Background technique [0002] In the communication network, the network structure mostly presents a mesh network structure. Due to the failure of the wired network link or the movement of nodes in the wireless network, the network topology will change. At present, various routing protocols have certain loop avoidance mechanisms. However, under a large-scale network structure, it is still difficult to ensure that routing loops will not be formed when the network topology changes, especially for distance vector routing protocols. Due to the time difference of routing update messages, routing loops are more likely to occur, so various routing protocols simultaneously It also has its own loop breaking mechanism. After a routing loop occurs, the link state routing protocol can complete the loop breaking process within a few minutes, and the distance vector ...
