Degree is based on this, and the new bandwidth credit in the channel QQ is 4M, and the new bandwidth credit in the channel FTP is 2M.
Table 2
Idle bandwidth is determined according to Tidle threshold and line bandwidth for the third traffic requests information, wherein empty
Not busy bandwidth is equal to Tidle threshold multiplied by line bandwidth；The floating mark in w channel indicates that the bandwidth credit in channel can be adjusted if it exists
It is whole, then judge in w channel with the presence or absence of request flow be greater than own channels bandwidth credit channel, the w be less than or
Equal to the natural number of channel number；X request flow is greater than the channel of the bandwidth credit of own channels if it exists, then by idle band
Width subtract the constant or reduced bandwidth credit of value as a result, according to floating priority order of priority, be followed successively by it is same float it is excellent
The channel of first grade is distributed according to the preset ratio in the channel of same floating priority；The bandwidth that each channel is assigned to as pair
The new bandwidth credit in channel is answered, the x, which is less than or equal to float, identifies the natural number of number, i.e., in the process of bandwidth allocation
In, the channel of highest priority is first distributed, then the channel distribution of secondary high priority, until being assigned to the logical of lowest priority
Road or idle bandwidth distribute.Here, reduce or constant bandwidth credit refers to the channel for being unable to adjust bandwidth credit and the
The bandwidth credit of the bandwidth credit in one channel.
It is exemplary, the identifier of floating priority is 0,1 ..., n, wherein 0 indicates highest priority, and 1 indicates time high
Priority, n indicate that lowest priority, n are greater than 1 integer, and as shown in table 3, t moment a, route includes two channel QQ
Channel and the channel FTP, and the request flow of the two is both greater than bandwidth credit, and has floating capacity on the channel QQ, wherein QQ floats
Priority 1 is lower than FTP floating priority 0, and the bandwidth so the channel FTP can preferentially float, the channel QQ is in the channel FTP floating bandwidth
Could float bandwidth later, be based on this, and the new bandwidth credit in the channel FTP is 5M, and the new bandwidth credit in the channel QQ is idle
Remaining 1M in bandwidth.
Table 3
Further, the method also includes: if the bandwidth availability ratio of the broadband line be greater than preset Tidle threshold,
Then keep the bandwidth credit in the channel of the broadband line.
Embodiment two
The embodiment of the present invention provides a kind of flow control methods, is applied to volume control device, as illustrated in fig. 2, it is assumed that certain
Section (9:00 to 18:00 of Mon-Fri) carries out flow control to the broadband line of corporate networks at work for company, wherein
The broadband line can be divided into three channels: the channel FTP, the channel QQ and IE browser channel, and in t moment, t is greater than 0, this method
May include:
Step 201, the line bandwidth and route flow for obtaining broadband line.
Step 202, line bandwidth and route flow according to broadband line, determine the bandwidth availability ratio of broadband line.
Step 203 judges whether the bandwidth availability ratio of broadband line is less than or equal to preset Tidle threshold, if so,
Execute step 204；If it is not, thening follow the steps 210.
If the bandwidth availability ratio of step 204, broadband line is less than or equal to preset Tidle threshold, broadband line is obtained
Channel traffic requests information.
Wherein, traffic requests information may include the bandwidth credit, each of the request flow in each channel, each channel
The floating priority of the floating mark and each channel in channel.The content of traffic requests information, which can be, repeatedly to be obtained, and is not necessarily to
It must once obtain.
Step 205, according to Tidle threshold and line bandwidth, determine idle bandwidth.
Specifically, idle bandwidth is equal to Tidle threshold multiplied by line bandwidth.For example, Tidle threshold is 60%, line bandwidth
It is 10M, correspondingly, idle bandwidth is 6M；Tidle threshold is 90%, and line bandwidth is 10M, correspondingly, idle bandwidth is 9M.
Step 206, to judge that the floating in each channel identifies whether be 1, if so, thening follow the steps 207；If it is not, then executing
Step 210.
In the present embodiment, the mark that floats can be 1 or 0 two identifier, wherein 1 indicates the ability with adjustment, 0 table
Show the ability without adjustment.
The floating mark in step 207, if it exists w channel is all 1, then judges in w channel with the presence or absence of request flow
Less than the channel of the bandwidth credit of own channels, if so, thening follow the steps 208；If it is not, thening follow the steps 209.
Step 208, request flow is less than or equal to the channel of the bandwidth credit of own channels if it exists, then asking channel
Seek new bandwidth credit of the flow as corresponding channel.
For example, as shown in table 4, in t moment, it is 20*60%=12M, the band broad forehead in the channel FTP that idle bandwidth, which is calculated,
Degree 2M is greater than request flow 1M and the 1M in 12M is therefore distributed to the channel FTP.
Table 4
Step 209, idle bandwidth is subtracted above-mentioned channel new bandwidth credit as a result, by idle bandwidth dispensing remaining
The high channel of floating priority in channel, the bandwidth that the high channel of the priority that floats is assigned to, will as new bandwidth credit
Remaining idle bandwidth distributes to the low channel of floating priority.
In the present embodiment, the identifier of floating priority is 0 or 1, wherein 0 indicates high priority, and 1 indicates low priority.
As shown in table 4, the floating priority in the channel QQ is higher than the channel IE, and the bandwidth credit in the channel IE cannot float, therefore, by (12-1)
10M in M distributes to the channel QQ, finally, the idle bandwidth of (12-10-1) M is distributed to the channel IE as new bandwidth credit.
It is worth noting that when request flow is less than or equal to the bandwidth credit of own channels, without considering that priority is asked
In other words topic requests the priority for the case where flow is less than or equal to own bandwidth amount to be higher than any priority-level；When
It is above-mentioned logical there is no when the channel for the bandwidth credit for requesting flow to be less than or equal to own channels, no longer needing to subtract idle bandwidth
The new bandwidth credit in road as a result, direct dispense idle bandwidth.
Step 210, channel bandwidth credit remain unchanged.
The embodiment of the invention provides a kind of more careful flow control methods, pass through the request stream to each channel
Amount, the bandwidth credit in each channel, the floating mark in each channel and the floating priority in each channel are handled, and are determined
The bandwidth of adjustment is needed most, to meet the demand for needing most the channel of flow at this time.
