Method and device for detecting message sending rate

Abstract

The invention provides a method and device for detecting the message sending rate. The method comprises the steps that the cache size of an interchanger is monitored; whether the catch state of the interchanger is about to reach the maximum extent or not is judged according to the cache size; when the catch state of the interchanger is about to reach the maximum extent, whether the priority of a message to be forwarded is high or low is judged; the interchanger receives the message or directly discards the message according to the priority judgment on the message. According to the method, the cache size of the interchanger is monitored in real time, when the catch size reaches the preset cache threshold value of a system, the interchanger is marked, the message with high priority can occupy the cache of the interchanger at any time, a message with low priority occupies the cache space of the interchanger only when the cache of the interchanger is not used up, and therefore the forwarding time delay of the messages can be shortened in the forwarding process.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a method and device for detecting message sending rate. Background technique [0002] When deploying data center applications, the response time of the application depends not only on the overall computing power of the cluster, but also on the data forwarding delay of the cluster network. Forwarding delay is a very important network performance parameter. The business has high requirements on data forwarding delay. For example, web search, social network, etc. have relatively high requirements on data forwarding delay. Therefore, a low data forwarding delay can ensure a good user experience. How to reduce data The data forwarding delay of the center is the focus that the industry pays more attention to at present. [0003] The data center has corresponding requirements for its network: since short data streams are often real-time information, it implements low latency for sh...

Problems solved by technology

Currently, there are two strategies. One is to minimize the data cached by packets on network devices, that is, the transmission control protocol of the data center uses the new explicit congestion notification (ECN) function in the Combined with the control strategy at the source end, it can reduce the completion time of the data flow, but cannot determine the appropriate data flow speed

Another method is to explicitly calculate and allocate the data flow rate for each flow. This scheme can achieve good network performance, but this scheme is more complicated, and it is difficult to implement and deploy, especially in multiple networks. When deploying on the device, the difficulty will increase exponentially
