Method and device for monitoring packet loss rate based on fpga

Abstract

The present invention relates to a method and device for monitoring packet loss rate based on FPGA. The method comprises: the local FPGA receives the message sent by the peer FPGA; when the message is the first common message, recording the reception of the first common message when the message is the first protocol message, fill the current receiving count value into the first protocol message; according to the current sending count value carried by the first protocol message, the last sending count value, the last Calculate the packet loss rate of the local link based on the count value of the second reception, the current reception count value, and the preset interval for sending protocol packets. According to the requirement of measuring the packet loss rate, the invention configures the generation strategy of the protocol message, sends the protocol message for measuring the packet loss rate, and reduces the occupation of limited network bandwidth resources. At the same time, the original ordinary packets in the network are used to record and monitor the packet loss rate in the link without affecting the available bandwidth of the network, which reduces the impact on the network environment in the later stage and improves the availability of the network.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for monitoring the packet loss rate based on FPGA (Field-Programmable Gate Array) in the network link quality monitoring technology. Background technique [0002] With the continuous development of data communication technology, the design of communication equipment continues to be complicated, and the number of communication equipment connected to the communication network system continues to increase, making the stability of these communication equipment facing challenges. When the operator debugs the communication equipment, the link is not smooth or the information packet is lost. [0003] Currently, a method of measuring the link packet loss rate is to add a count / sequence number to the message, and measure the link packet loss rate through the count / sequence number. The method includes a process in which at least two maintenance endpoints period...

Problems solved by technology

[0004] Although the above method only needs to calculate the packet loss rate through the packet serial number, the process is fast and convenient, and can improve the convenience of LM (low-voltage version mobile processor) performance monitoring, but this method is difficult for users due to the introduction of measurement packets. The original packet flow has a great impact, and it always needs to actively initiate a dedicated measurement packet flow, which will occupy a large amount of network bandwidth resources, resulting in the normal communication of the network being greatly affected or even interrupted when measuring the packet loss rate. The normal communication of the network increases the difficulty of bandwidth overhead of the network system and reduces the usability of the system
