Below in conjunction with specific embodiment, flow statistic device of the present invention and method are described in detail.
Embodiment
In the present embodiment, suppose there are 4096 bridge interface (BP in the system for statistics, Bridge Port), each BP comprises 4096 VLAN (VLAN, Virtual Local Area Network) or GemPort, here, for VLAN, each VLAN comprises 8 802.1P, described 802.1P can think the sub-interface under VLAN, and wherein, described BP is equivalent to aforesaid physical interface, described VLAN is equivalent to aforesaid logic interfacing, and described 802.1P is equivalent to aforesaid sub-interface; Below for this system, illustrate function and the implementation procedure thereof of each several part component units of embodiment of the present invention flow statistic device.
Generation unit 201, for the address information according to multiple interface to be counted, be that the storage address information of the statistics of statistical information that described in each, interface correspondence is arranged and interface described in each generates corresponding statistical mask;
Table 1 is the structural representation of embodiment of the present invention statistical mask, as shown in table 1, described statistical mask comprises address information (VLAN/Gem Port ID) and (802.1P/EthType) of statistical index (Statistics_Index), statistical information and interface to be counted; Wherein, described statistical index is the storage address information of the statistics of described interface.
In Table 1, these 12 bit bit representation statistical indexs of bit18 ~ bit29, these 12 bit positions can represent 2 altogether
12=4096 logical number, therefore, can add up at most 4096 traffic statistics results, and these 4096 traffic statistics results are all stored in a slice RAM, the address phase one_to_one corresponding of the address that each traffic statistics result stores in RAM and statistical index; That is: the address corresponding to RAM that in statistical index, address is concrete, and the address of this RAM stores the traffic statistics result corresponding to statistical mask content;
Here, described statistical index adopts 12 bit positions to represent, those skilled in the art can increase accordingly according to actual conditions or reduce the bit wide in this territory, such as, if only need add up 10 flows, the bit wide of so described statistical index can only have four bit positions.
Table 1
In Table 1, Bit3 ~ bit17 comprises altogether 15 bit positions, and wherein, these 12 bit positions of bit6 ~ bit17, are used for mating in statistical index the address of the VLAN under the BP arranged; These three bit positions of bit3 ~ bit5, for mating the 802.1P address under the VLAN address that arranges in bit6 ~ bit17.The implication of this 15 bit of Bit3 ~ bit17 is: only belong to the BP arranged in statistical index, and the packet belonging to the 802.1P coupling of VLAN and bit3 ~ bit5 setting that bit6 ~ bit17 is arranged just is added up, and by the RAM corresponding to statistics Cache Statistics index.
Described statistical information comprises measurement type and statistics option, and in the present embodiment, do not do any setting to measurement type, the quantity being defaulted as packet is added up; In Table 1, the statistics option in these three bit bit representation statistical informations of bit0 ~ bit2, these three bit positions can represent altogether 8 logical number, and so add up in option and can represent 8 at most, in the present embodiment, the concrete meaning of statistical information is as follows:
When parameter=000, represent and forbid statistics;
When parameter=001, represent the statistics of carrying out BP;
When parameter=010, represent the statistics of carrying out VLAN ID under BP;
When parameter=011, represent the statistics of carrying out Gem Port under BP;
When parameter=100, represent the statistics of carrying out 802.1P under BP;
When parameter=101, represent the statistics of carrying out VLAN ID+802.1P under BP;
Here, statistics this territory of option is represented with 3bit in described statistics option, those skilled in the art can increase accordingly according to actual conditions or reduce the bit wide in this territory, namely, if the excursion of the middle variable of statistical information is larger, then can increase the bit wide in this territory, such as, be increased to 5bit or more from 3bit; If the excursion of the middle variable of statistical information is less, then can reduces the bit wide in this territory, such as, reduce to 2bit from 3bit.Those skilled in the art can also change the concrete meaning of option each in statistical information according to actual needs accordingly, repeats no more here.
The using method of the statistical mask in the present embodiment shown in table 1 is described below by two examples.Example 1: to add up the ID of BP0(BP or address be 0,0 binary representation be 0,000 0,000 0000, represent binary low level with right) flow, corresponding to adding up 001 in option in table 1; And the binary representation traffic statistics result of BP0 being stored in the address 5(5 storing RAM is 0,000 00000101) in, then the configuration information of this stream is as shown in table 2:
| Name | Bit(s) |
| Statistics_Index | 0000 0000 0101 |
