Router and switch etc. carry out the network equipment of data retransmission, its data-forwarding rate generally adopts bit/s to represent, that is, when the interface identifying a certain network equipment is 100M, the interface of this network equipment can support the forwarding rate of 100Mbit per second.But in fact data transmit with the form of packet, so identify may occur deviation with above-mentioned data-forwarding rate.This is because when the packet major part of a certain interface transmission is all 1024 byte, this interface can reach the speed of 100Mbit/s, but when the packet major part of this interface transmission is all 64 byte, this interface can only reach the speed of 50Mbit/s.
Therefore in order to identify the data-forwarding rate of a certain interface accurately, data-forwarding rate can adopt pps to identify, and pps is the number of the packet that can forward per second.Such as when the data-forwarding rate identifying a certain interface is 30Mpps, then represent that this interface is per second and can forward 30M packet, and wherein the length of each packet adopts the minimum length of packet to identify, be 64 bytes for this packet of Ethernet, be 40 bytes for light mouth (Packet over SDH, POS) this packet.
In addition, along with carrying out of data service, the data-forwarding rate of user to the network equipment carrying out data retransmission proposes more and more higher requirement, but also can improve accordingly along with the price of the raising network equipment of data-forwarding rate.Therefore in order to improve the speed of data retransmission and reduce the cost of system, carrying out generally along with data service, is added up data traffic by the mounted network equipment, for upgrading network equipment afterwards provides foundation.
But in prior art, when calculating network traffics, generally determine according to the byte number of the packet that each time point forwards, but for the transmission of data, it is sudden very large, i.e. the byte number that the packet of this network equipment of some time points transmission comprises may be larger, but the byte number that the packet of this network equipment of another time point transmission comprises may be fewer, therefore the statistical method of these network traffics, the network traffics of the determination network equipment that cannot be accurate and effective.
