What in fact BBU reported can also comprise: the total logic port number on the total bandwidth value of physical port, physical port.

When initialization, in memory resource pool, the unassigned bandwidth of all physical ports is the total bandwidth of physical port;

When initialization, in memory resource pool, the unallocated logic port number of all physical ports is total logic port number of physical port.

When initialization, in memory resource pool, the state of all logic ports is unallocated, and bandwidth value is 0.

Resource pool is made up of multiple BBU, and a BBU that can pre-set When building their networks in resource pool is master control BBU, and BBU in a resource pool also can be allowed by competition generation master control BBU.Other BBU is the BBU of non-master control, the BBU of master control can communicate with the BBU of non-master control, the BBU of each non-master control can by the mark of the mark of the physical port under this BBU and the logic port associated with the mark of described physical port, and the using state information of described physical port, the using state information of described logic port, unappropriated logic port under described physical port under unappropriated bandwidth value and described physical port quantity on offer the BBU of master control.

For there being the BBU of multiple physical port can belong to two or more resource pools, but each physical port on BBU can only belong to a resource pool.

Each BBU has a physical port at least, and each physical port has corresponding bandwidth value, as 10M/100M/1000M.Each physical port creates multiple logic port, and the default bandwidth value of unappropriated logic port is 0, after configuring certain bandwidth value for logic port, can distribute to traffic application device and use.The bandwidth sum of all logic ports on a physical port generally can not exceed the bandwidth of this physical port.

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

There are 3 BBU in a resource pool, are respectively BBU1, BBU2 and BBU3, and, BBU1, BBU2 and BBU3 only have a physical port, certainly, just illustrate in this application scene, in fact have more BBU in a resource pool, each BBU also has multiple physical port.

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

Table 3: physical port table

Table 4: logical end oral thermometer

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

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

Traffic application device APP1 applies for the 50M bandwidth on BBU1 to BBU2, BBU2 checks that 50M does not exceed the bandwidth application upper limit of APP1, the state that BBU2 distributes under the physical port 1-1 on BBU1 is unappropriated logic port 1-1-1, and the bandwidth value arranging logic port 1-1-1 is set to 50M, and allocation result is returned APP1.When the business of APP1 increases, when traffic application device APP1 increases 50M bandwidth to BBU2 application, with logic port mark 1-1-1 in application, BBU2 checks that the 50M=100M of the logical port bandwidth used of APP1 new application for 50M adds is less than the bandwidth application upper limit of 200M, and check that the unassigned bandwidth of the physical port 1-1 described in logic port 1-1-1 is 50M, the requirement increasing application can be met, the bandwidth value of logic port 1-1-1 is set to 100M.When business continues to increase, traffic application device APP1 increases the 50M bandwidth of logic port 1-1-1 to BBU2 application, and the unassigned bandwidth of the physical port 1-1 that BBU2 checks belonging to logic port 1-1-1 is 0, and this application increases bandwidth failure.APP1 can bandwidth application 50M again, instead of application increases bandwidth 50M.Master control BBU2 checks that logical port bandwidth value that APP1 used is less than the bandwidth application upper limit of 200M for 50M+50M=100M, then select another physical port in resource pool, as physical port 2-1, and a state of distributing on physical port 2-1 is unappropriated logic port 2-1-1, the bandwidth arranging logic port 2-1-1 is 50, and returns application response.

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

Spendable transfer resource after table 5:APP1 application

Sequence number	Logic port identifies	Bandwidth value	Using state
				1	1-1-1	100	Distribute
2	2-1-1	50	Distribute

The resource status in the rear transfer resource pond of APP1 application is consulted table 6 and table 7 and is understood:

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

Logical port information in resource pool after table 7:APP1 application

Traffic application device APP2 applies for the 50M bandwidth on BBU2 to BBU2, BBU2 checks that 50M does not exceed the bandwidth application upper limit of APP2, and BBU2 there is unassigned bandwidth be the physical port 2-1 of 50M, the state that master control BBU2 distributes on physical port 2-1 is unappropriated logic port 2-1-2, and the bandwidth value arranging logic port 2-1-2 is 50M, return application response to APP2.When the business of APP2 increases, APP2 newly can apply for the bandwidth of 50M, or application increases the bandwidth 50M of logic port 2-1-2, application in this example increases the 50M bandwidth meeting failure of logic port 2-1-2, because the unassigned bandwidth on the physical port 2-1 belonging to logic port 2-1-2 is 0.

When APP1 and APP2 traffic carrying capacity declines, the logic port that the bandwidth can applied for BBU2 application minimizing or release have been applied for, the example that the concrete process reducing bandwidth sum release logic port can be consulted above is understood, and this place does not do and too much repeats.
