Problems solved by technology

For example, when a low-priority packet is relatively large, Tp may be exhausted instantaneously. At this time, if a high-priority packet arrives, the packet has to be discarded due to insufficient Tp token

Embodiment Construction

[0033] The technical solution in this application will be described below with reference to the accompanying drawings.

[0034] The technical solutions of the embodiments of the present application can be applied to various forwarding devices in the data communication field. For example, the forwarding device can be a router, and the router can forward Internet protocol (internet protocol, IP) messages; or the forwarding device can be a network The switch, the network switch can forward the Ethernet frame; or the forwarding device can also be other devices, devices or chips capable of forwarding messages, which is not limited in this embodiment of the present application.

[0035] In the field of data communication, a message may need to be forwarded by multiple forwarding devices before reaching the destination. Taking the forwarding device as a router as an example, figure 1 A network structure diagram provided for this application. see figure 1 , the network structure di...

Abstract

The invention provides a method and a device for transmitting a message. The method comprises: receiving a first message; and when the number of tokens required for forwarding the first message is greater than the number of tokens in a first token bucket and less than or equal to the number of tokens in a second token bucket, forwarding the first message, the filling rate of the first token bucketbeing greater than or equal to the filling rate of the second token bucket. According to the method for transmitting the message in the embodiment of the invention, the probability that the message is discarded during congestion can be reduced.

Description

technical field [0001] The present application relates to the field of communications, and more specifically, to a method and device for transmitting messages. Background technique [0002] With the rapid development of network technology, it is usually necessary to perform flow control on the traffic sent by users. The so-called flow control refers to adopting different committed access rates (committed access rates, CARs) for transmission control of data packets transmitted in the network. The basic principle of the CAR algorithm is that the system fills the token-bucket with tokens at a certain filling rate. Each token represents a bit. When a message comes, it will need to pass The length of the message is compared with the number of tokens in the token bucket. If the number of tokens in the token bucket is greater than or equal to the length of the message, the message is forwarded; otherwise, the message is discarded, thereby achieving the purpose of limiting traffic....
