Data transmitting method and communication nodes

Abstract

The invention discloses a data transmitting method and communication nodes so as to improve the balance of the flow of an exchange plane for the communication between the communication nodes and improve the utilization rate of a physical bandwidth of the exchange plane. The data transmitting method comprises the following steps: a first communication node determines that to a first port corresponding to a first exchange plane is adopted to transmit data to a second communication mode; when the total data transmitting rate of the first communication mode at the first port is over a set transmitting rate threshold, a second exchange plane is selected from other exchange planes for connecting the first communication node and the second communication node; and the first communication node transmits the data to the second communication node through the port of the second exchange plane. By adopting the technical scheme of the invention, the balance of the flow of the exchange plane for the communication between the communication nodes can be improved, and thus, the utilization rate of the physical bandwidth of the exchange plane is improved.

Description

technical field [0001] The present invention relates to the field of communication, in particular to a data transmission method and a communication node. Background technique [0002] After entering the information age, people communicate more and more frequently. One of the main ways of communication is telephone communication. Information can be communicated quickly between people through the phone. Therefore, how to ensure the reliability of communication equipment is a become more of a concern.

[0003] In the field of communication, in order to increase the reliability of information exchange between different communication nodes, communication nodes (ie, CE) are usually interconnected with multiple switching planes; communication nodes are interconnected through multiple switching planes, which not only increases It improves the reliability of communication between different communication nodes and the freedom of switching plane selection, and also introduces the possibility of unbalanced loads on different switching planes; for example, when communication node A needs to send data to communication node B, because communication node A It is connected with communication node B through multiple switching planes, therefore, communication node A can randomly select one of the switching planes to send data to communication node B; therefore, the following technical defects may exist in the existing data transmission method: multiple A communication node selects the same switching plane to send data to other communication nodes or receive data from other communication nodes at a certain moment, resulting in the over-bandwidth of the sending port and / or receiving port of the switching plane, which causes problems such as packet loss. , which affects the reliability of data transmission; in addition, because each communication node sends or receives data independently, there is still a problem that a large number of data packets cannot reach a certain communication node in order, such as the need to send or receive data packets in order , which requires additional processing by the CPU. Due to the huge number of data packets, it may lead to problems with large CPU processing overhead and delay.

Although the existing communication method solves the problem of communication reliability to a certain extent, there are still the following technical problems: (1) the switching plane is set as a dedicated switching plane, and there may be a problem that is actually allocated to the switching plane. The physical bandwidth cannot be fully utilized. For example, when sending user signaling and user service data at the same time, there may be surplus physical bandwidth of the switching plane used to send user signaling and physical bandwidth of the switching plane used to send user service data Insufficient, or the physical bandwidth of the switching plane used to send user signaling is not enough and the physical bandwidth of the switching plane used to send user service The problem of poor bandwidth utilization; (2) when the switching plane adopts the active-standby mode to work, when the switching plane in the main state is working, other switching planes in the backup state are idle, so the switching planes in the backup state The physical bandwidth of the switching plane can only be idle and cannot be fully utilized; moreover, there are multiple switching planes between two communication nodes, and it is difficult to determine which switching plane is used as the main switching plane and which switching plane is used as the backup switching plane

[0005] To sum up, in the existing communication mode between communication nodes, the data transmission traffic of the switching plane is unbalanced, which leads to the problem of low physical bandwidth utilization of the switching plane.
