The QOS technology mainly implements bandwidth allocation through network speed limit, which generally refers to configuring speed limit rules on traffic forwarding devices such as routers, switches, network cards, etc., when traffic of a specified IP address flows through these forwarding devices, the forwarding devices can limit the speed of traffic that meets the speed limit rules, discard traffic that exceeds the speed limit value, and share bandwidth is a total speed limit value shared by user devices of multiple IP addresses.
Referring to fig. 1, fig. 1 shows a schematic diagram of a network architecture of a shared bandwidth system, where a primary network device 101 may be connected to at least one secondary network device, as shown in fig. 1, the primary network device 101 is respectively connected to a secondary network device 102a and a secondary network device 102b, and each secondary network device may be connected to at least one user device, as shown in fig. 1, the secondary network device 102a may be respectively connected to a user device 103a, a user device 103b, and a user device 103 c; the secondary network device 102b may be connected to the user device 103d, the user device 103e, and the user device 103f, respectively. The first-level Network device 101 may be a router, a Network Address Translation (NAT) gateway, and other switching devices, and may be used to implement data exchange between a wide area Network and a local area Network, the second- level Network devices 102a and 102b may be switches, routers, and other traffic forwarding devices, and the user devices 103a and 103b … … 103f may be computers, mobile phones, and other mobile terminals, which is not limited in this application. In the process of forwarding the traffic, the user equipment 103a sends the traffic to the secondary network equipment 102a connected thereto, and then the secondary network equipment 102a sends the traffic to the primary network equipment 101, so as to perform data interaction with the external network through the primary network equipment 101.
In the related art, if the bandwidth of the ue is to be limited, the primary network device needs to set a bandwidth limiting rule for each secondary network device, and then each secondary network device needs to set a bandwidth limiting rule for each ue connected to the secondary network device.
For example, to solve the above problem, the present application provides a method for implementing a shared bandwidth, so that multiple user equipments can share the bandwidth while being limited by the maximum bandwidth that can be used by each user equipment, thereby avoiding that an individual user equipment occupies too much bandwidth. Fig. 2 is a flowchart illustrating a method for implementing bandwidth sharing according to an exemplary embodiment of the present application. Taking the network architecture shown in fig. 1 as an example, the method applied to the primary network device 101 may include the following steps:
step 202: establishing a corresponding relation between the IP address of each user equipment and a parent bandwidth threshold value and a sub-bandwidth threshold value; the sub bandwidth threshold is used for performing bandwidth limitation on corresponding user equipment, and the parent bandwidth threshold is used for performing bandwidth limitation on secondary network equipment connected with the corresponding user equipment.
In an embodiment, in order to improve the bandwidth limitation, that is, the update efficiency of the sharable bandwidth value, mapping relationships between the parent bandwidth threshold and the parent bandwidth threshold ID of each value and between the sub-bandwidth threshold and the sub-bandwidth threshold ID of each value may be established in advance. After determining the parent bandwidth threshold and the sub-bandwidth threshold to be limited by the IP address of each user equipment, determining the parent bandwidth threshold ID and the sub-bandwidth threshold ID corresponding to the parent bandwidth threshold and the sub-bandwidth threshold according to the established mapping relationship, thereby determining the corresponding relationship between the IP address of the user equipment and the parent bandwidth threshold ID and the sub-bandwidth threshold ID, and combining the corresponding relationship with the mapping relationship between the parent bandwidth threshold ID and the parent bandwidth threshold value, and between the sub-bandwidth threshold ID and the sub-bandwidth threshold value in the bandwidth sharing implementation process, that is, determining the corresponding relationship between the IP address of each user equipment and the parent bandwidth threshold value and the sub-bandwidth threshold value. The corresponding relation between the IP address of the user equipment and the parent bandwidth threshold ID and the sub-bandwidth threshold ID can be stored in a key-value key value pair form, and the key-value key value pair is stored in a tree structure as a tree node so as to be convenient to store and index.
By setting the corresponding threshold ID for the bandwidth threshold, when updating the bandwidth value to be limited by each device, it is not necessary to update each threshold value in the limitation policy, but only the mapping relationship between the threshold and the ID needs to be updated. Taking the network architecture shown in fig. 1 as an example, the secondary network device 102a is connected to the user device 103a and the user device 103b, and the corresponding parent bandwidth threshold is 100Mbit/s, the IP address of the user device 103a is 1.1.1.1, and the corresponding sub-bandwidth threshold is 20 Mbit/s; the IP address of the user equipment 103b is 2.2.2.2, and the corresponding sub-bandwidth threshold is 50 Mbit/s; a threshold ID may be established: 1000 and bandwidth threshold: 100Mbit/s, threshold ID: 1001 bandwidth threshold 20Mbit/s, threshold ID: 1002 and a bandwidth threshold 50Mbit/s, when recording the correspondence between the IP address of the user equipment and the parent bandwidth threshold and the sub-bandwidth threshold, the IP address of each user equipment may be regarded as a key, and the corresponding sub-bandwidth threshold ID and parent bandwidth threshold ID may be regarded as a value, and for the user equipment 103a, the mapping may be recorded as a key: 1.1.1.1, value: 1000 and 1001; for the user device 103b, it can be recorded as key: 2.2.2.2, value: 1000 and 1002. If the bandwidth allocated to the secondary ue 102a needs to be updated to 200Mbit/s, only the bandwidth threshold 100Mbit/s mapped by the threshold ID1000 needs to be updated to 200Mbit/s, and the key-value values corresponding to the ue 103a and the ue 103b do not need to be changed, so that the data parameters to be modified during updating are reduced, and the updating efficiency is improved.
Step 104: and performing bandwidth limitation on any user equipment according to the established corresponding relation so that the actual bandwidth allocated to any user equipment does not exceed the sub-bandwidth threshold corresponding to the IP address of any user equipment and the actual bandwidth allocated to the secondary network equipment connected with any user equipment does not exceed the parent bandwidth threshold corresponding to the IP address of any network equipment.
In an embodiment, when any user equipment sends a message to a secondary network device connected to the user equipment, a target parent bandwidth threshold and a target sub-bandwidth threshold corresponding to an IP address of the user equipment sending the message are determined according to a correspondence between the IP address of each user equipment and a parent bandwidth threshold and a sub-bandwidth threshold. If the correspondence between the IP address of each user equipment and the parent bandwidth threshold and the sub-bandwidth threshold is such that the IP address and the corresponding threshold ID are stored in the tree structure in the key-value form, the tree structure may be queried according to the IP address of the user equipment that sends the packet to obtain the corresponding target parent bandwidth threshold ID and the target sub-bandwidth threshold ID, and then the target parent bandwidth threshold corresponding to the target parent bandwidth threshold ID and the target sub-bandwidth threshold corresponding to the target sub-bandwidth threshold ID are determined according to the mapping relationship between the parent bandwidth threshold and the parent bandwidth threshold ID of each value and the sub-bandwidth threshold ID of each value.
Based on the target sub-bandwidth threshold and the target parent bandwidth threshold corresponding to the user equipment to be limited, which are determined, the smaller value of the target parent bandwidth margin and the target sub-bandwidth threshold can be selected as the target bandwidth threshold, and bandwidth limitation is performed on any user equipment according to the target bandwidth threshold. The target parent bandwidth margin is a residual bandwidth threshold which is not allocated to other user equipment connected with the same secondary network equipment as the any user equipment in the target parent bandwidth threshold. If the flow rate of the message sent by any user equipment is greater than the corresponding target bandwidth threshold, the secondary network equipment connected with the user equipment can perform packet loss processing on the flow rate exceeding the target bandwidth threshold. Taking the network architecture shown in fig. 1 as an example, the secondary network device 102a is connected to the user equipment 103a, the user equipment 103b, and the user equipment 103c, the parent bandwidth threshold of the secondary network device 102a is 100Mbit/s, the sub-bandwidth threshold of the user equipment 103a is 20Mbit/s, and the sub-bandwidth threshold of the user equipment 103b is 50 Mbit/s. If the secondary network device 102a has allocated 60Mbit/s of its parent bandwidth threshold to the user device 103c, then for the user device 103a, the current target sub-bandwidth threshold is 20Mbit/s, the target parent bandwidth margin is 40Mbit/s, at this time, the target bandwidth threshold is smaller than the target parent bandwidth margin, the target sub-bandwidth threshold of 20Mbit/s is selected as the target bandwidth threshold of the user device 103a, and if the user device 103a sends 25Mbit/s traffic to the secondary network device 102a, the 5Mbit/s traffic is discarded; for the user equipment 103b, the target sub-bandwidth threshold is 50Mbit/s, the target parent bandwidth margin is 40Mbit/s, and at this time, the target sub-bandwidth threshold is greater than the target parent bandwidth margin, and the target parent bandwidth margin 40Mbit/s is selected as the target bandwidth threshold of the user equipment 103b, and if the user equipment 103b sends 30Mbit/s of traffic to the secondary network equipment 102a, the secondary network equipment 102a may forward all the traffic sent by the user equipment 103 b. The smaller value of the sub-bandwidth threshold of the user equipment and the parent bandwidth margin of the secondary network equipment connected with the user equipment is used as a target bandwidth threshold for limiting the bandwidth of the user equipment, so that the user equipment can share the parent bandwidth of the secondary user equipment connected with the user equipment under the limit of the sub-bandwidth threshold of the user equipment.
Furthermore, each user equipment may also preset a priority for the IP address of each user equipment, except that each user equipment occupies the parent bandwidth according to a first-come-last principle, so that when any user equipment accesses, if the target child bandwidth threshold of the user equipment is smaller than the target parent bandwidth threshold margin, the user equipment with the priority lower than that of any user equipment may be determined in other user equipment connected with the same secondary network equipment, so as to reduce the actual bandwidth allocated to the determined user equipment, update the current target parent bandwidth margin, and determine the target bandwidth threshold of any user equipment based on the updated target parent bandwidth margin. By setting the priority to the IP address of the user equipment, the bandwidth resources can be flexibly and preferentially allocated to the user equipment with higher priority according to the user requirement.
In an embodiment, the sub-bandwidth threshold corresponding to each ue may be an interval number, and the selecting a smaller value of the target parent bandwidth margin and the target sub-bandwidth threshold as the target bandwidth threshold may include: when the target parent bandwidth allowance is larger than the interval maximum value of the target child bandwidth threshold, selecting the interval maximum value as a target bandwidth threshold; when the target parent bandwidth allowance is larger than the interval minimum of the target sub-bandwidth threshold and smaller than the interval maximum of the target sub-bandwidth threshold, any value which is not larger than the target parent bandwidth allowance and not smaller than the interval minimum can be selected as the target bandwidth threshold; when the target parent bandwidth allowance is smaller than the interval minimum value of the target child bandwidth threshold, the target parent bandwidth allowance can be selected as the target bandwidth threshold. Taking the network architecture shown in fig. 1 as an example, the user devices 103d, 103e, and 103f are all connected to the secondary network device 102b, if the parent bandwidth threshold of the secondary network device 102b is 30Mbit/s, the sub-bandwidth threshold corresponding to the user device 103d is [10,20] Mbit/s, the sub-bandwidth threshold corresponding to the user device 103e is [5,15] Mbit/s, and the sub-bandwidth threshold corresponding to the user device 103f is [10,15] Mbit/s, if the message of the user device 103d first enters the secondary network device 102b, at this time, the parent bandwidth margin of the secondary network device 102b is 30Mbit/s, and is greater than the interval maximum of the sub-bandwidth threshold [10,20] Mbit/s of the user device 102b, the interval maximum of 20Mbit/s is selected as the target bandwidth threshold of the user device 103 d; if the secondary network device 102b has allocated the 20Mbit/s parent bandwidth threshold to the user device 103d, the message of the user device 103e also enters the secondary network device 102b, and at this time, the target parent bandwidth margin of the secondary network device 102b is 10Mbit/s, and the interval minimum value 5Mbit/s which is greater than the sub-bandwidth threshold [5,15] Mbit/s of the user device 103e is less than the interval maximum value 15Mbit/s, then 7Mbit/s which is not greater than the target parent bandwidth margin 10Mbit/s and not less than the interval minimum value 5Mbit/s can be selected as the target bandwidth threshold of the user device 103 e; if the message of the user equipment 103f subsequently enters the secondary network device 102b, and the parent bandwidth threshold 30Mbit/s of the secondary network device 102b already allocates 20Mbit/s to the user equipment 103d for use, and allocates 7Mbit/s to the user equipment 103e for use, the target parent bandwidth margin is 3Mbit/s, and is smaller than the interval minimum value of the sub-bandwidth threshold [10,15] Mbit/s of the user equipment 103f, the target parent bandwidth margin 3Mbit/s is selected as the target bandwidth threshold of the user equipment 103 f.
On the basis, when the secondary network device allocates part of the parent bandwidth threshold to other network devices, so that the target parent bandwidth margin is smaller than the interval maximum value of the target child bandwidth threshold of any user device to be allocated currently, the actual bandwidth allocated to other user devices connected with the same secondary network device as the any user device can be reduced, and the target parent bandwidth margin is updated; wherein the updated target parent bandwidth margin is used to determine the target bandwidth threshold. Based on the above example, after the secondary network device 102b has allocated 20Mbit/s of its parent bandwidth threshold 30Mbit/s to the user device 103d, when allocating a target bandwidth threshold to the user device 103e, the target parent bandwidth margin 10Mbit/s is less than the interval maximum 15Mbit/s of the sub-bandwidth threshold [5,15] Mbit/s of the user device 103e, the actual bandwidth allocated to the user device 103d connected to the same secondary network device 102b as the user device 103e may be reduced, e.g., the target bandwidth threshold 20Mbit/s of the user device 103d may be reduced to 15Mbit/s, at which time the target parent bandwidth margin of the secondary network device 102b is updated to 15bit/s, and the updated target parent bandwidth margin 15Mbit/s and the sub-bandwidth threshold [ 5] of the user device 103e are reused on the basis, 15Mbit/s to determine a target bandwidth threshold for the user equipment 103 e.
Further, when the actual bandwidth allocated to other user equipments connected to the same secondary network device as any user equipment is reduced, the actual bandwidth allocated to each other user equipment connected to the same secondary network device as any user equipment may be reduced to the minimum interval value of the sub-bandwidth threshold corresponding to each user equipment; alternatively, the actual bandwidth allocated to each other ue connected to the same secondary network device as the any ue may be reduced by the same percentage; alternatively, each user equipment may be provided with a priority in advance, and when the actual bandwidth allocated to another user equipment is reduced, the actual bandwidth allocated to a user equipment with a relatively lower priority may be reduced preferentially. Based on the above example, after the secondary network device 102b has allocated 20Mbit/s of its parent bandwidth threshold 30Mbit/s to the user device 103d and 7Mbit/s to the user device 103e, when allocating the target bandwidth threshold to the user device 103f, the actual bandwidth allocated to the user device 103d may be reduced to the minimum of 10Mbit/s of its intervals [10,20] Mbit/s and the actual bandwidth allocated to the user device 103e may be reduced to the minimum of 5Mbit/s of its intervals [5,15] Mbit/s; or it may be reduced by the same percentage, for example, the actual bandwidth of the user equipment 103d is reduced by 10% together with the actual bandwidth of the user equipment 103e, so that the actual bandwidth of the user equipment 103d is reduced to 18Mbit/s, and the actual bandwidth of the user equipment 103e is reduced to 6.3Mbit/s, it should be understood that this is not all examples presented here, and the present application is not limited to the actual method for reducing the bandwidth. By setting the sub-bandwidth threshold of the user equipment as the interval number, the bandwidth threshold can be more flexibly distributed to each user equipment when the bandwidth of the parent bandwidth is shared, so that each user equipment can occupy more bandwidth resources when the parent bandwidth resources are more abundant, the utilization rate of the bandwidth resources is improved, the occupied bandwidth of the user equipment is timely adjusted when the parent bandwidth resources are more scarce, and the influence on other user equipment to use the parent bandwidth resources is avoided.
Besides the three-level network structures of the primary network device, the secondary network device, and the user device, the network structure of the implementation method for sharing bandwidth disclosed in the present application may also be multi-level, for example, the implementation method may be applied to the primary network device, where the primary network device is connected to at least one secondary network device, each secondary network device is connected to at least one tertiary network device … …, each N-1-level network device is connected to at least one N-level network device, and each N-level network device is connected to at least one user device, which is not limited in this application. In the multi-level network architecture, only the corresponding relationship among the corresponding sub-bandwidth threshold, the first-level bandwidth threshold and the second-level bandwidth threshold … … N-level bandwidth threshold needs to be established, and the available bandwidth of each level of network equipment can be limited according to the corresponding relationship, so that the final user equipment bandwidth and the bandwidth of each level of network equipment corresponding to the final user equipment bandwidth do not exceed the bandwidth limit of the user equipment bandwidth.
According to the technical scheme provided by the application, the sub-bandwidth threshold value used for carrying out bandwidth limitation on each user equipment and the parent bandwidth threshold value used for carrying out bandwidth limitation on each secondary network equipment are uniformly set on the primary network equipment, so that the bandwidth used by each user equipment when the parent bandwidth of the secondary network equipment is shared can be flexibly limited, and the condition that the use of other user equipment is influenced by too much bandwidth resources occupied by individual user equipment is avoided. The network architecture shown in fig. 1 is taken as an example, and is described in detail with reference to fig. 3. Fig. 3 is a flow chart illustrating a multi-party interaction of a method for implementing bandwidth sharing according to an exemplary embodiment of the present application. As shown in fig. 3, the interaction process between the user equipment 103a, the user equipment 103b, the secondary network equipment 102a and the primary network equipment 101 includes the following steps:
in step 301, the user equipment 103a sends traffic to the secondary network device 102 a.
For example, the IP address of the user equipment 103a is 1.1.1.1, and 30Mbit/s of traffic is sent to the secondary network equipment 102 a.
In step 302, the secondary network device 102a determines the actual bandwidth that can be allocated to the user device 103 a.
The secondary network device 102a queries a pre-established correspondence between the IP address of each user device and the parent bandwidth threshold and the sub-bandwidth threshold, and in the embodiment of the present application, the correspondence between the IP address of each user depth and the parent bandwidth threshold and the sub-bandwidth threshold is stored in a tree structure in which the IP address and the threshold ID key value pair are stored. For example, it can be determined by querying the tree structure that the parent bandwidth threshold ID corresponding to IP address 1.1.1.1 is 1000 and the sub-bandwidth threshold ID is 1001. And according to a pre-established threshold ID: 1000 and bandwidth threshold: 100Mbit/s, threshold ID: 1001 bandwidth threshold 20Mbit/s, threshold ID: 1002 and the bandwidth threshold of 50Mbit/s, it can be determined that the parent bandwidth threshold corresponding to the user equipment 103a is 100Mbit/s and the sub-bandwidth threshold is 20 Mbit/s.
If the secondary network device 102a has already allocated the 60Mbit/s bandwidth to the user device 103c, it may determine that the current parent bandwidth threshold margin is 40Mbit/s, compare the parent bandwidth margin with the sub-bandwidth threshold, and determine the smaller sub-bandwidth threshold 20Mbit/s of the target parent bandwidth margin and the target sub-bandwidth threshold as the target bandwidth threshold of the user device 103a, that is, the actual bandwidth that may be allocated to the user device 103 a.
In step 303, the secondary network device 102a performs packet loss on the received traffic.
And comparing the size of the traffic sent by the user equipment 103a with the actual bandwidth which can be allocated to the user equipment 103a, and dropping 10Mbit/s of the 30Mbit/s of traffic sent by the user equipment 103a, which is more than 20Mbit/s of actual bandwidth which can be allocated to the user equipment 103 a.
In step 304, the secondary network device 102a sends the packet-lost traffic to the primary network device 101.
In step 305, the user device 103b sends traffic to the secondary network device 102 a.
For example, the IP address of the user equipment 103b is 2.2.2.2, and 10Mbit/s of traffic is sent to the secondary network equipment 102 a.
The secondary network device 102a determines 306 the actual bandwidth that can be allocated to the user device 103 b.
As described above, the secondary network device 102a may determine that the parent bandwidth threshold ID corresponding to IP address 2.2.2.2 is 1000 and the sub-bandwidth threshold ID is 1002 by querying the tree structure. And according to a pre-established threshold ID: 1000 and bandwidth threshold: 100Mbit/s, threshold ID: 1001 bandwidth threshold 20Mbit/s, threshold ID: 1002 with a bandwidth threshold of 50Mbit/s, it can be determined that the parent bandwidth threshold corresponding to the user equipment 103b is 100Mbit/s and the sub-bandwidth threshold is 50 Mbit/s.
Since the secondary network device 102a has already allocated the 60Mbit/s bandwidth to the user device 103c and allocated the 20Mbit/s bandwidth to the user device 103a, the current parent bandwidth threshold margin may be determined to be 20Mbit/s, the parent bandwidth margin may be compared with the sub-bandwidth threshold, and the smaller parent bandwidth threshold margin 20Mbit/s of the target parent bandwidth margin and the target sub-bandwidth threshold may be determined as the target bandwidth threshold of the user device 103b, i.e. the actual bandwidth that may be allocated to the user device 103 b.
In step 307, the secondary network device 102a sends traffic to the primary network device 101.
Since the traffic 10Mbit/s sent by the user equipment 103b is less than the actual bandwidth 20Mbit/s that the secondary network device 102a can allocate to the user equipment 103b, the secondary network device 102a can forward all the traffic sent by the user equipment 103b to the primary network device 101.
