Fig. 1 is embodiment of the present invention channel statistical multiplexing method flow chart.
Reference Fig. 1, the channel statistical multiplexing method following steps described in the present embodiment:
Step s101, the working condition of each pseudo channel in monitoring physical channel.
Wherein, physical channel is the channel being made up of physical entity, and pseudo channel is a kind of logical partitioning to data.Respectively
Individual pseudo channel belongs to same physical channel.The working condition of tunnel includes but is not limited to the bandwidth of tunnel.Prison
The working condition of survey pseudo channel includes the working condition monitoring each pseudo channel.
Step s102, when the working condition monitoring pseudo channel changes, according to each pseudo channel described
Pre-set priority carries out bandwidth to each pseudo channel described and redistributes.
Wherein, monitoring lead pseudo channel working condition change including: monitor the work of at least one pseudo channel
Change as state.When the working condition monitoring at least one pseudo channel changes, you can according to described each
The pre-set priority of pseudo channel carries out bandwidth to each pseudo channel described and redistributes.Each pseudo channel described default
Priority represents and can be preferably the high virtual channel allocation bandwidth of priority.
Referring to Fig. 2, in an embodiment, the pre-set priority of each pseudo channel described in described basis is to each void described
Intend channel to carry out bandwidth and redistribute comprising the following steps:
Step s201, is respectively allocated required minimum bandwidth for each pseudo channel described.
Wherein, the total bandwidth of described physical channel is the first bandwidth.Small band needed for each described pseudo channel described
Wide sum is the second bandwidth.Described first band is wider than described second bandwidth.
For example, pseudo channel includes vc1、vc2…vcnCommon n pseudo channel, n is the integer more than or equal to 2.Each is empty
The minimum bandwidth intending channel is followed successively by bmin1、bmin2…bminn, the maximum bandwidth of each pseudo channel is followed successively by bmax1、bmax2…
bmaxn.The total bandwidth of physical channel is b, the i.e. a width of b of first band.The minimum bandwidth sum of the pseudo channel in all workingLess than bandwidth b of physical channel, i=1,2 ..., n.Then, be respectively allocated for each pseudo channel described required
After minimum bandwidth, the unassigned bandwidth of the first band alleviating distention in middle-JIAO of physical channel is
Step s202, according to the pre-set priority of each pseudo channel described, by the unallocated band of described first band alleviating distention in middle-JIAO
Width distributes to partial virtual channel or whole pseudo channel in each pseudo channel described.
As a kind of embodiment, the implementing process and can be of step s202:
Each pseudo channel described is sorted from high to low according to pre-set priority；

Pseudo channel carries out bandwidth allocation；
If described difference is more than or equal to the unassigned bandwidth of first band alleviating distention in middle-JIAO, for described previous priority pseudo channel
Reallocate the corresponding bandwidth of unassigned bandwidth of described first band alleviating distention in middle-JIAO, and each pseudo channel described is redistributed complete.
For example, with reference to Fig. 3, for vc1、vc2…vcnCommon n pseudo channel, pre-set priority successively decreases successively.For first
Unassigned bandwidth b with alleviating distention in middle-JIAOrem, virtual according to carrying out from the pseudo channel reallocation of highest priority up to the principle divided
Channel width is distributed.Specifically, if unassigned bandwidth b of first band alleviating distention in middle-JIAOremPseudo channel vc less than limit priority1's
Maximum bandwidth and difference b of minimum bandwidthrem<bmax1-bmin1, then by whole bremDistribute to pseudo channel vc1, otherwise by first band
Unassigned bandwidth b of alleviating distention in middle-JIAOremMiddle a part of bandwidth allocation is to pseudo channel vc1So that vc1Bandwidth allocation to maximum bandwidth
bmax1, then more remaining bandwidth is sequentially allocated by this rule, until unassigned bandwidth b of first band alleviating distention in middle-JIAOremIt is zero.
The bandwidth being assigned rear n pseudo channel is respectively b1、b2…bn.So far then complete the real-time theory calculating pseudo channel
Transfer rate.
