Method and device for counting messages of output/input port of exchange equipment

Abstract

The invention discloses a method for counting messages of output / input port of exchange equipment, which comprises the following steps: marking data packets by three colors including red, yellow and green by dual-rate three-color marker algorithm when the message enters the exchange equipment from the input port of the exchange equipment; in the input port, counting the numbers of the red and green data packets and the number of bytes by a configured access control list (ACL) rule, obtaining the number of the yellow data packet of the input port and the number of bytes by the total number of the data packet received by the input port, and obtaining the number of the yellow data packet discarded by the input port and the number of bytes by the total number of the data packet discarded by the input port; and in the output port, counting the numbers of the green and yellow data packets and the number of bytes by the configured access control list (ACL) rule, and counting the numbers of the yellow, red and green data packets discarded by the output port by a register based on the output port; The invention also discloses a device for counting the messages of output / input port of the exchange equipment; thus, the message information can be counted conveniently and flexibly, and the counting method is also quite simple.

Description

technical field [0001] The invention relates to a communication equipment packet statistics technology, in particular to a method and a device for statistics of outgoing and incoming port packets of switching equipment. Background technique [0002] Flow control plays a very important role in the communication network. It can effectively use the resources of the communication system, and at the same time, it can ensure the stable operation of the system and meet the customer's demand for service quality. For example: in the Internet, sometimes the performance of the server will be reduced due to the server processing too many packets. If the flow control technology is used, the server can not be overloaded, thereby ensuring the performance of the network equipment. In addition, the current raging viruses on the Internet increase the load on the network, and sometimes even cause the network to be paralyzed. The use of flow control can reduce the network load to a certain exte...

Problems solved by technology

[0005] First, because the collected network data has not undergone any processing, the data volume is very large, so the performance requirements for the data collection database are very high, and the corresponding requirements for the hard disk space of the machine are also high, and it also causes a certain loss to the network bandwidth. ;At the same time, due to the large amount of statistical information, it is difficult to choose a good collection interval, and as the network usage changes, the interval may be very inapplicable, resulting in the loss of statistical information, and the statistical information cannot be displayed conveniently;

[0006] Second, because the statistical information must be sent to a server regularly, and the server will perform subsequent processing at the end, the traffic statistics cannot be completely completed on the local client, so the implementation is complicated and takes up a lot of resources

[0007] Another kind is the method that firewall (Firewall) statistics rejected message, and this method carries out statistics to the message that is rejected by firewall by the statistical function that firewall self provides, and the shortcoming of this method is: only can count out the message that is rejected by firewall The total number of packets, but cannot provide detailed statistical information
