Positioning incoming and outgoing packet statistical method based on breeboot programmable switching chip

Abstract

The invention discloses a positioning incoming and outgoing packet statistical method based on a breeboot programmable switching chip, which is used for carrying out real-time statistics on the flow of a fixed quintuple at an incoming and outgoing port. In the process of real-time statistics, the following scheme is adopted: after a positioning rule is bound to a fixed port, port input and output flows are matched through the rule, if the port input and output flows are hit, counting statistics operation is carried out, and when a display command is input into an upper layer or a display button is clicked, a count is obtained from beareboot statistics, and the counting is carried out. And the flow input and output quantity is displayed in a web or command line interface. According to the method, the specific flow inlet and outlet condition can be directly observed, display is more visual, timely adjustment of equipment strategies is facilitated, and economic losses are avoided. During the operation period of the shunting equipment, the problem positioning time can be greatly shortened, the manpower and the operation and maintenance cost are saved, and the equipment throughput can be twice that of the original equipment.

Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a method for counting incoming and outgoing packets based on a barefoot programmable switching chip. Background Art

[0002] With the continuous development of communication technology, the application of splitters is increasing, and the demand for the performance of related products is getting higher and higher. Related products often need to accept customer customization requirements. However, due to the high complexity of line network traffic, the equipment is not clear about the direction of the required traffic during use, which can easily cause traffic leakage, great difficulty in positioning, and difficulty for customers to use. Therefore, in order to facilitate customers to intuitively locate the traffic direction of the equipment during use, how to implement a method for counting incoming and outgoing packets is a difficult point. Summary of the invention

[0003] To solve the above problems, the present invention proposes a method for locating inbound and outbound packets based on a barefoot programmable switching chip, which performs real-time statistics on the traffic of a fixed five-tuple at the inbound and outbound ports. In the process of real-time statistics, the patent adopts the following scheme: after the positioning rule is bound to a fixed port, if the port input and output traffic are matched, the statistics are written to the calculated location. When the upper layer inputs a display command or clicks a display button, the count is obtained from the barefoot statistics, and the traffic input and output quantities are displayed in the web or command line interface.

[0004] The specific steps are as follows: Step 1: Because the number of inbound and outbound traffic of the specified five-tuple needs to be counted, the inbound port and the outbound port to be counted are first bound, and the rule matching five-tuple and the rule number are written into the Barefoot matching table, and the statistical space is allocated.

[0005] Step 2: If traffic is input into or output from a port, first determine whether the port belongs to the port of the binding positioning rule. If it is determined to be a binding port, match the five-tuple parsed by the message with the rule matching table added to barefoot in step 1. If a match is found, obtain the rule number and port number.

[0006] Step 3: The corresponding statistics writing position is calculated by the rule number and port number, and the underlying statistics of barefoot are increased by one.

[0007] Step 4: When the operator enters a command to display the statistics of incoming and outgoing packets, the packet statistics are obtained by obtaining the location written in step 3 of the barefoot bottom layer and displayed on the operator's web interface or command line.

[0008] Compared with the prior art, the technical solution of the present invention has the following significant beneficial effects: 1. This patented method can directly observe the specific flow in and out, and the more intuitive display is conducive to timely adjustment of equipment strategies to avoid economic losses.

[0009] 2. This patented method can greatly shorten the time for locating problems during the operation of the diversion equipment, saving manpower and operation and maintenance costs.

[0010] 3. This patented method can be operated during the operation of the diversion device to avoid restarting the device or interrupting the device function due to problem location, which will affect the economic benefits generated.

[0011] 4. This patented method increases the throughput of the device by 2 times, and puts the statistics of incoming and outgoing packets, which were previously not good at processing, on a suitable barefoot switch, thus enhancing the competitiveness of the product.
