Problems solved by technology

Due to the limitations of the current CPU processing capacity, the CPU cannot send a relatively large number of test packets in an "instantaneous" period, and the bandwidth of the test packet flow cannot be very large, so it is impossible to achieve throughput and other tests that are closely related to bandwidth.
[0008] 2. Long-term continuous testing requires the software process responsible for sending messages to occupy the limited processing resources of the CPU, which will directly affect the CPU's response and proc

Embodiment Construction

[0061] The main purpose of the present invention is to provide a practical online message flow monitoring and bandwidth compensation scheme, which is implemented by Field Programmable Gate Array (FPGA, Field Programmable Gate Array), and the CPU only needs to be responsible for simple auxiliary configuration work , The buffering, construction, sending of the message and the real-time measurement of the bandwidth of the service message are completely completed by the FPGA. Therefore, the scheme of the present invention can realize the compensation / insertion work of the large-bandwidth test message flow; it can perform long-time and large-quantity message compensation work; it can monitor the bandwidth value of the service message flow of interest in real time, and complete the work accordingly Threshold bandwidth difference flow compensation function can be set; the length, content, frame gap, burst (burst packet flow) quantity, etc. of the packets used for flow compensation can...

Abstract

The invention discloses a device for online message flow monitoring and bandwidth compensation, which comprises a message identification module 102, a message storage module 103, a message scheduling module 104, a bandwidth measurement module 105 and an inserted message generation module 107. The invention additionally discloses a method for online message flow monitoring and bandwidth compensation. The technical scheme of the invention is that service messages required to be compensated are determined in real time on the transmission path of the service messages, the bandwidth of the service messages is measured in real time and whether compensation messages are inserted or not is determined according to measurement results. The invention has the advantages that the compensation/insertion of large bandwidth testing message flow can be realized; the long-term and large-quantity message compensation can be conducted; and the bandwidth value of the interested service message flow can be monitored in real time and thereby the threshold-configurable bandwidth difference value flow compensation function can be completed.

Description

technical field [0001] The invention relates to the technical field of Ethernet, in particular to a method and device for online packet flow monitoring and bandwidth compensation. Background technique [0002] In recent years, with the rapid development of Ethernet technology in the field of metropolitan area network, operators have more and more requirements for Ethernet equipment to be manageable and operable. In order to meet the above demands, an online monitoring technology that does not affect the normal business of users has emerged as the times require. [0003] Online means that the flow of business packets will not be affected, including the need not to suspend the forwarding of user traffic, and will not cause packet loss in the flow of business packets, and will not disrupt the sequence of service packets. Monitoring requires inserting a test flow into the message flow, and realizing the purpose of monitoring by measuring the test flow. The configuration requir...
