Method and device for monitoring packet loss rate based on an FPGA (Field Programmable Gate Array)

Abstract

The invention relates to a method and device for monitoring a packet loss rate based on an FPGA (Field Programmable Gate Array). The method comprises the following steps of: receiving a message, which is sent by the FPGA of an opposite terminal, by the FPGA of a home terminal; when the message is a first ordinary message, recording a receiving count value in the event of receiving the first ordinary message; when the message is a first protocol message, filling the currently received count value in the first protocol message; and calculating the packet loss rate of a home terminal link according to a currently sent count value carried in the first protocol message, a previously sent count value, a previously received count value, the currently received count value and a pre-set protocol message sending spacing interval. In the invention, according to a requirement for measuring the packet loss rate, a generation policy of the protocol message is configured; the protocol message for measuring the packet loss rate is sent; the occupation of a limited network bandwidth resource is reduced; simultaneously, by using the original ordinary message in the network, in the event of not influencing the available bandwidth of the network, the packet loss rate in the link is recorded and monitored; the influence to the network environment in a later period is reduced; and the network availability is improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for monitoring packet loss rate based on FPGA (Field-Programmable Gate Array, Field-Programmable Gate Array) in network link quality monitoring technology. Background technique [0002] With the continuous development of data communication technology, the design of communication equipment is becoming more and more complicated, and the number of communication equipment connected to the communication network system is increasing, which makes the stability of these communication equipment face challenges. When the operator debugs the communication equipment, the link is not smooth or the information packet is lost. [0003] At present, a method for measuring the packet loss rate of a link is: adding a count / serial number to a packet, and measuring the link packet loss rate by the count / serial number. The method includes a process in which at least...

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
