In the embodiment of the invention, when the professional end of transmission of traffic application device, traffic application device can send bandwidth to master control BBU and discharge request, and master control BBU can be according to the request of traffic application device, discharge the original logic port 1-1-1 that uses, the bandwidth value of logic port 1-1-1 is set to 0.

For the ease of understanding, be example with a concrete application scenarios below, the process of the control method of transmission bandwidth in the embodiment of the invention is described:

3 BBU are arranged in the resource pool, be respectively BBU1, BBU2 and BBU3, and, BBU1, BBU2 and BBU3 have only a physical port, certainly, just illustrate in this application scene, in fact have more BBU in a resource pool, also have a plurality of physical ports on each BBU.

Total transfer resource in the resource pool can be consulted table 3 and understand:

Table 3: physical port table

Table 4: logical end oral thermometer

The total bandwidth that can be read BBU1 by table 3 is 100M, and the total bandwidth of BBU2 is 100M, and the total bandwidth of BBU3 is 1000M, and it is the master control BBU of resource pool that BBU2 is set, and is in charge of all physics port resources in the resource pool, and manages business with the bandwidth application of device.

Now hypothesis has traffic application device APP1, traffic application device APP2, and be that the bandwidth application upper limit that two traffic application device are set all is 200M.

The 50M bandwidth of traffic application device APP1 on the BBU2 application BBU1, BBU2 checks that 50M does not exceed the bandwidth application upper limit of APP1, state under the physical port 1-1 on the BBU2 distribution BBU1 is unappropriated logic port 1-1-1, and the bandwidth value that logic port 1-1-1 is set is set to 50M, and allocation result is returned APP1.When the business of APP1 increases, when traffic application device APP1 increases the 50M bandwidth to the BBU2 application, have logic port sign 1-1-1 in the application, BBU2 checks that the logic port bandwidth of having used of APP1 adds that as 50M the 50M=100M of new application is less than the bandwidth application upper limit of 200M, and the unassigned bandwidth that checks the described physical port 1-1 of logic port 1-1-1 is 50M, can satisfy the requirement that increases application, the bandwidth value of logic port 1-1-1 is set to 100M.When business continued to increase, traffic application device APP1 was to the 50M bandwidth of BBU2 application increase logic port 1-1-1, and BBU2 checks that the unassigned bandwidth of the physical port 1-1 under the logic port 1-1-1 is 0, and this application increases bandwidth and fails.APP1 is bandwidth application 50M again, rather than application increases bandwidth 50M.Master control BBU2 checks that the logic port bandwidth value that APP1 has used is the bandwidth application upper limit of 50M+50M=100M less than 200M, then select another physical port in the resource pool, as physical port 2-1, and a state on the distribution physical port 2-1 is unappropriated logic port 2-1-1, the bandwidth that logic port 2-1-1 is set is 50, and returns the application response.

If APP1 applies for the 100M bandwidth again, master control BBU2 checks that the logic port bandwidth that APP1 has used is 100M+50M, adds the 100M of application greater than the bandwidth application upper limit 200M of APP1, and BBU2 can return the application failure, and provides failure cause.Like this, the operable transfer resource in APP1 application back can be consulted table 5 and understands:

The spendable transfer resource in table 5:APP1 application back

Sequence number	The logic port sign	Bandwidth value	The use state
				1	1-1-1	100	Distribute
2	2-1-1	50	Distribute

The resource status in transfer resource pond, APP1 application back consults table 6 and table 7 is understood:

Physical port information in the resource pool after the table 6:APP1 application

Logic port information in the resource pool after the table 7:APP1 application

The 50M bandwidth of traffic application device APP2 on the BBU2 application BBU2, BBU2 checks that 50M does not exceed the bandwidth application upper limit of APP2, and it is the physical port 2-1 of 50M that unassigned bandwidth is arranged on the BBU2, it is unappropriated logic port 2-1-2 that master control BBU2 distributes the state on the physical port 2-1, and the bandwidth value that logic port 2-1-2 is set is 50M, returns the application response to APP2.When the business of APP2 increases, APP2 can newly apply for the bandwidth of 50M, perhaps application increases the bandwidth 50M of logic port 2-1-2, application in this example increases the 50M bandwidth of logic port 2-1-2 can fail, because the unassigned bandwidth on the physical port 2-1 under the logic port 2-1-2 is 0.

When APP1 and APP2 traffic carrying capacity descend, can reduce the bandwidth of having applied for or discharge the logic port of having applied for to the BBU2 application, the process that specifically reduces bandwidth and discharge logic port can be consulted top example and understood, and does not do too much and give unnecessary details at this place.
