Embodiment
Below by drawings and Examples, technical scheme of the present invention is described in further detail.
Fig. 1 is the flow chart of flow limitation method embodiment of the present invention.As shown in Figure 1, this flow limitation method may further comprise the steps:
In communication network, the network equipment for example NPE can detect each sub-tunnel, and the flow that obtains each sub-tunnel is the data volume that per second passes through in the sub-tunnel.Before obtaining flow, can set up a plurality of sub-tunnels according to the difference of concrete business, and should be bundled in the main tunnel in a plurality of sub-tunnels, common way be the private network tunnel that will set up between the UPE as sub-tunnel, with the public network tunnel set up between the NPE as main tunnel.But do not get rid of main tunnel is that private network tunnel, sub-tunnel are the public network tunnel, and perhaps main tunnel and sub-tunnel are all the situation in private network tunnel or public network tunnel.Be that the private network tunnel set up between main tunnel, the UPE is that the situation in sub-tunnel is that example describes with the public network tunnel of setting up between the NPE in the present embodiment.
A plurality of sub-tunnels are bundled into a method on the main tunnel to be had multiple.When wherein the flow in existing main tunnel is 100Mbps, sub-tunnel can only bundle the 100Mbps total bandwidth, even distribute the bandwidth resources that also take main tunnel when the sub-tunnel of bandwidth does not have flow not moving business, and the flow in other sub-tunnels can't be assigned to the bandwidth resources in main tunnel, thereby has caused the waste of main tunnel bandwidth resource.NPE can be bundled in a plurality of sub-tunnels on the main tunnel according to the convergence ratio of sub-tunnel and the binding of main tunnel in the present embodiment.Convergence ratio is meant the ratio of first bandwidth in the bandwidth sum in all sub-tunnels that can be bundled in the main tunnel and main tunnel, and first bandwidth is the maximum bandwidth value in main tunnel.Wherein convergence ratio can be " 2: 1 ", " 3: 1 ", " 4: 1 " etc., and convergence ratio can set in advance on NPE according to the professional transfer bandwidth demand of reality.According to the needs of concrete business, the size of adjusting the last convergence ratio of NPE just can be controlled the total bandwidth in the sub-tunnel that is bundled into main tunnel flexibly.Fig. 6 is the application scenarios schematic diagram of flow control methods of the present invention.As shown in Figure 6, first bandwidth of supposing the main tunnel FE3 that sets up between NPE is 100Mbps, the sub-tunnel TE1 that sets up between UPE, the 3rd bandwidth of TE2, TE4 are respectively 50Mbps, 50Mbps, 100Mbps, and wherein the 3rd bandwidth is meant the maximum bandwidth value in each sub-tunnel.If convergence ratio is " 2: 1 ", then can be that sub-tunnel TE1, TE2 and the TE4 of 200Mbps is bundled on the main tunnel with total bandwidth.If the flow sum in all sub-tunnels, for example: among TE1, TE2 and the TE4 all flow sum less than 100Mbps then this TE3 can export normally, but, then need the flow in neutron tunnel, main tunnel is limited if the flow sum in all sub-tunnels surpasses the bandwidth constraints value in main tunnel.
In fact the flow sum in all sub-tunnels is exactly the flow in main tunnel in the main tunnel, when the flow in main tunnel during greater than first bandwidth in main tunnel, need abandon a part of flow can with the flow restriction in main tunnel first bandwidth in.Can abandon which partial discharge according to the relevant priority decision in sub-tunnel.The priority that its neutron tunnel is relevant can comprise: the multiple priority such as priority of the service priority in sub-tunnel, the priority in sub-tunnel and sub-tunnel group.The priority that sub-tunnel is relevant can set in advance.According to the priority in the service priority in sub-tunnel, sub-tunnel or the priority of sub-tunnel group, can exceed first bandwidth at the flow in main tunnel, abandon the business in the sub-tunnel, sub-tunnel or sub-tunnel group according to priority order from low to high, with the flow restriction in main tunnel in first bandwidth.
Wherein, NPE can be divided into the sub-tunnel in the main tunnel different sub-tunnel groups.Fig. 7 is the schematic diagram of flow control methods neutron of the present invention tunnel group, as shown in Figure 7, comprising in the main tunnel 75 can a plurality of sub-tunnels group 71, comprises at least one sub-tunnel 73 in each sub-tunnel group 71, is further limited according to the flow in 71 pairs of main tunnels 75 of group, sub-tunnel.The type in its neutron tunnel 73 can be the user scope in this sub-tunnel, user class, type of service, amount of bandwidth, service quality etc.Can comprise a plurality of professionally 77 in each sub-tunnel 73, can comprise a plurality of sub-tunnels 73 in each sub-tunnel group 71, can comprise a plurality of sub-tunnels group 71 and/or a plurality of sub-tunnel 73 in each main tunnel 75.
In step 102, NPE can be divided into following several situation according to the method that the relevant priority in different sub-tunnels limits the flow in main tunnel:
Situation one, the priority that sub-tunnel is relevant are the service priority in sub-tunnel.Fig. 2 is the flow chart of flow limitation method embodiment situation one of the present invention, and as shown in Figure 2, step 102 can comprise following any one or a plurality of step:
Because all there is i.e. the 3rd bandwidth of a maximum bandwidth value in each sub-tunnel, business that can first antithetical phrase tunnel internal is done bandwidth constraints one time, promptly in advance with each delineation of activities priority of sub-tunnel internal, can preferentially successfully transmit to guarantee the high business of priority.Particularly, when the flow that detects this sub-tunnel exceeds the 3rd bandwidth,, abandon the business of the low priority in the sub-tunnel earlier, till the flow in each sub-tunnel is less than or equal to the 3rd bandwidth in sub-tunnel according to service priority order from low to high.After the flow restriction in each sub-tunnel is in the 3rd bandwidth in sub-tunnel, can prevent that the flow in sub-tunnel from exceeding the maximum bandwidth value that transmits in sub-tunnel, also can limit the flow that from main tunnel, transmits to a certain extent simultaneously.For example: the 3rd bandwidth of sub-tunnel TE1 and TE2 all is 50M, but need be through the flow of the transmission of TE1 and TE2 for being respectively 60Mbps and 40Mbps, then will abandon 10Mbps through the lower business of service priority in the sub-tunnel of TE1, other business could normally transmit from TE1, TE2.
Each sub-tunnel group can set in advance i.e. second bandwidth of a maximum bandwidth value.After the execution in step 201, NPE can also detect and obtain the flow and second bandwidth of sub-tunnel group, if the flow of this sub-tunnel group promptly the flow sum in interior all the sub-tunnels of this sub-tunnel group do not exceed second bandwidth, then the business in sub-tunnel can normal transmission; If the flow of this sub-tunnel group exceeds second bandwidth, then execution in step 202 according to the service priority in sub-tunnel with the flow restriction of sub-tunnel group in second bandwidth, be specially: according to the service priority order from low to high in sub-tunnel, abandon the low business of priority in sub-tunnel in the sub-tunnel group earlier, till the flow of each sub-tunnel group is less than or equal to second bandwidth in sub-tunnel, can guarantee the successful transmission of the business that the priority in sub-tunnel is high.The flow of its neutron tunnel group is the flow sum in all sub-tunnels in the sub-tunnel group.For example: sub-tunnel TE1 and TE2 belong to same sub-tunnel group TE12, the 3rd bandwidth of TE1 and TE2 all is 50Mbps, second bandwidth of TE12 is 70Mbps, after execution in step 201, when the flow of TE1 and TE2 was limited in 50Mbps and 40Mbps respectively, the flow sum of TE1 and TE2 was 90Mbps, greater than the second bandwidth 70Mbps, after will abandoning 20Mbps through the lower business of service priority in the sub-tunnel of TE1, other business could be from TE1, TE2, TE12 normal transmission.
Wherein, the second bandwidth sum of the sub-tunnel of all in main tunnel group can have certain relation with first bandwidth in main tunnel, for example: when the second bandwidth sum of each sub-tunnel group is less than or equal to first bandwidth, just can guarantee after the execution in step 202 that the business that priority is high in the sub-tunnel successfully transmits.In addition, if execution in step 201 not, behind the flow in all sub-tunnels that obtain according to step 101, calculate the flow of each sub-tunnel group, relatively whether the flow of each sub-tunnel group exceeds second bandwidth, execution in step 202 when the flow of this sub-tunnel group exceeds second bandwidth then.
After execution of step 201, whether the flow sum of judging all sub-tunnels in the main tunnel i.e. flow in main tunnel exceeds first bandwidth; Perhaps after execution of step 202, whether the flow sum of judging all sub-tunnel groups in the main tunnel i.e. flow in main tunnel exceeds first bandwidth, if exceed, again according to the service priority in sub-tunnel with the flow restriction in main tunnel in first bandwidth.Be specially: if the flow in main tunnel is greater than first bandwidth, then can abandon the low business of priority in sub-tunnel in the main tunnel according to the service priority order from low to high in sub-tunnel, till the flow in main tunnel is less than or equal to first bandwidth in main tunnel, can successfully transmit to guarantee the business that priority is high in the sub-tunnel.Certainly, also not execution in step 201, step 202, when the flow sum in all sub-tunnels in the main tunnel during greater than first bandwidth, directly according to the service priority in sub-tunnel with the flow restriction in main tunnel in first bandwidth.
Situation two, the priority that sub-tunnel is relevant are the priority in sub-tunnel.Fig. 3 is the flow chart of flow limitation method embodiment situation two of the present invention, and as shown in Figure 3, step 102 can comprise following any one or a plurality of step:
Because when the sub-tunnel in the main tunnel was divided into sub-tunnel group, sub-tunnel group comprised at least one described sub-tunnel, the flow of sub-tunnel group is the flow sum in all sub-tunnels in the described sub-tunnel group.Can set in advance the priority in sub-tunnel, promptly priority is distinguished in each sub-tunnel.Then according to the priority in described sub-tunnel with the flow restriction of sub-tunnel group at the maximum bandwidth value of described sub-tunnel group promptly in second bandwidth, described sub-tunnel group comprises at least one described sub-tunnel.Be specially: the flow of group tunnel group is during greater than second bandwidth, the low sub-tunnel of priority order loss priority from low to high according to sub-tunnel, up to till the flow restriction of sub-tunnel group is in second bandwidth, wherein abandon sub-tunnel and be meant all business in this sub-tunnel that abandon.For example: sub-tunnel TE1 and TE2 belong to same sub-tunnel group TE12, the flow of TE1 and TE2 is respectively 60Mbps and 40Mbps, second bandwidth of TE12 is 70Mbps, the priority of TE1 is high, the priority of TE2 is inferior high, then NPE selection this moment abandons the business of the 40Mbps flow of TE2, the business of the 60Mbps flow of transmission TE1.
After execution in step 301, detect the flow in main tunnel, if the flow in main tunnel exceeds first bandwidth, then can also according to the priority in sub-tunnel with the flow restriction in main tunnel in first bandwidth.Be specially:, then can abandon the low sub-tunnel of priority in the main tunnel according to the priority order from low to high in sub-tunnel, till the flow in main tunnel is less than or equal to first bandwidth in main tunnel if the flow in main tunnel exceeds first bandwidth.
Wherein step 301,302 can not have sequential relationship yet, and any one step can be carried out separately or carry out simultaneously with other steps.Also execution in step 301 not directly detects and obtains the flow and first bandwidth in main tunnel, and execution in step 302 when the flow in main tunnel exceeded first bandwidth.
Situation three, the priority that sub-tunnel is relevant are set to the priority of sub-tunnel group.Be each sub-tunnel group differentiation priority.Then according to the priority of described sub-tunnel group, with the flow restriction in described main tunnel in described first bandwidth.The flow in main tunnel is specially: if then can abandon the sub-tunnel group in the main tunnel according to the priority order from low to high of sub-tunnel group, till the flow in main tunnel is less than or equal to first bandwidth in main tunnel greater than first bandwidth.The implication that wherein abandons sub-tunnel group is all sub-tunnels that abandon in the sub-tunnel group.According to the priority of sub-tunnel group with the flow restriction in main tunnel in first bandwidth in main tunnel, can guarantee that the business in all sub-tunnels in the high sub-tunnel group of priority can successfully be transmitted.
Present embodiment has guaranteed that the high business of priority can successfully transmit in flow restriction flow restriction first bandwidth in main tunnel in second bandwidth, main tunnel of flow restriction in the 3rd bandwidth, sub-tunnel group of service priority information with sub-tunnel according to sub-tunnel; Priority according to business, sub-tunnel, sub-tunnel group etc. is carried out the multilayer flow restriction, helps user's business is carried out hierarchical control and management; By carrying out flow restriction after on the network equipment in main tunnel convergence ratio being set setting up, can increase the total bandwidth that is bundled into the sub-tunnel on the main tunnel, thereby increase the total flow of passing through in the main tunnel, improve the utilance of bandwidth resources in the main tunnel.
