The embodiments of the present application will be described in detail.
The QOS technology mainly realizes bandwidth allocation through network speed limit, where network speed limit 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 the forwarding devices, the forwarding devices can limit the speed of the traffic conforming to the speed limit rules, discard the traffic exceeding the speed limit value, and share the bandwidth as a total speed limit value for sharing 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 connected to a secondary network device 102a and a secondary network device 102b, respectively, and each secondary network device may be connected to at least one user device, as shown in fig. 1, and the secondary network device 102a may be connected to a user device 103a, a user device 103b, and a user device 103c, respectively; the secondary network device 102b may be connected to the user device 103d, the user device 103e, and the user device 103f, respectively. The primary network device 101 may be a switching device such as a router or a NAT (Network Address Translation ) gateway, and may be used to implement data exchange between a wide area network and a local area network, the secondary network devices 102a and 102b may be traffic forwarding devices such as a switch and a router, and the user devices 103a and 103b … … f may be mobile terminals such as a computer and a mobile phone, which is not limited in the present application. In the process of forwarding the traffic, the user equipment 103a sends the traffic to the secondary network equipment 102a connected with the user equipment, 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 user equipment is to be limited, the bandwidth limiting rule for each secondary network equipment needs to be set on the primary network equipment, and then the bandwidth limiting rule for each user equipment connected with the secondary network equipment is set on each secondary network equipment, so that the configuration process is complicated and is inconvenient to perform unified management.
In order to solve the above-mentioned problems, the present application provides a method for implementing bandwidth sharing, so that a plurality of user equipments can share bandwidth and can be limited by the maximum bandwidth that can be used by each user equipment, thereby avoiding that individual user equipments occupy excessive bandwidth. Fig. 2 is a flow chart illustrating a method of implementing shared bandwidth 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 the corresponding relation between the IP address of each user equipment and the father bandwidth threshold value and the son bandwidth threshold value; the sub-bandwidth threshold is used for limiting the bandwidth of the corresponding user equipment, and the parent bandwidth threshold is used for limiting the bandwidth of the secondary network equipment connected with the corresponding user equipment.
In an embodiment, in order to improve the updating efficiency of the bandwidth limitation, that is, the bandwidth value that can be shared, mapping relations between the parent bandwidth threshold value and the parent bandwidth threshold ID of each value, and between the child bandwidth threshold value and the child bandwidth threshold ID of each value may be established in advance. After determining the father bandwidth threshold value and the son bandwidth threshold value to be limited by the IP address of each user equipment, determining the father bandwidth threshold value ID and the son bandwidth threshold value ID corresponding to the father bandwidth threshold value and the son bandwidth threshold value according to the established mapping relation, thereby determining the corresponding relation between the IP address of the user equipment and the father bandwidth threshold value ID and the son bandwidth threshold value ID, and combining the corresponding relation with the mapping relation between the father bandwidth threshold value ID and the father bandwidth threshold value, the son bandwidth threshold value ID and the son bandwidth threshold value in the bandwidth sharing realization process, so as to determine the corresponding relation between the IP address of each user equipment and the father bandwidth threshold value and the son bandwidth threshold value. The corresponding relation between the IP address of the user equipment and the father bandwidth threshold ID and the son bandwidth threshold ID can be saved in a key-value key value pair form, and the key-value key value pair form is used as a tree node to be stored in a tree structure 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, each threshold value in the limiting strategy is not required to be updated, and only the mapping relation between the threshold value and the ID is required 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, where 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 20Mbit/s; the IP address of the user equipment 103b is 2.2.2.2, and the corresponding sub-bandwidth threshold is 50Mbit/s; a threshold ID may be established: 1000 and bandwidth threshold: 100Mbit/s, threshold ID:1001 and bandwidth threshold 20Mbit/s, threshold ID:1002 and bandwidth threshold 50Mbit/s, when recording the correspondence between the IP address of the user equipment and the parent bandwidth threshold, the IP address of each user equipment may be used as a key, the corresponding child bandwidth threshold ID and parent bandwidth threshold ID may be used 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 equipment 103b, it may be recorded as a 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 key-value values corresponding to the ue 103a and the ue 103b do not need to be changed respectively, so that data parameters to be modified during updating are reduced, and updating efficiency is improved.
Step 104: and carrying out bandwidth limitation on any user equipment according to the established corresponding relation so that the actual bandwidth allocated to the any user equipment does not exceed a sub-bandwidth threshold corresponding to the IP address of the any user equipment, and the actual bandwidth allocated to the secondary network equipment connected with the any user equipment does not exceed a father bandwidth threshold corresponding to the IP address of the any user equipment.
In an embodiment, when any ue sends a message to a secondary network device connected to the ue, a target parent bandwidth threshold and a target child bandwidth threshold corresponding to an IP address of the ue sending the message are determined according to a correspondence between an IP address of each ue and a parent bandwidth threshold and a child bandwidth threshold. If the corresponding relation between the IP address of each user equipment and the parent bandwidth threshold value and the corresponding threshold value ID is that the IP address and the corresponding threshold value ID are stored in the tree structure in the key-value form, the tree structure can be queried according to the IP address of the user equipment sending the message to obtain the corresponding target parent bandwidth threshold value ID and the corresponding target child bandwidth threshold value ID, and then the target parent bandwidth threshold value corresponding to the target parent bandwidth threshold value ID and the target child bandwidth threshold value corresponding to the target child bandwidth threshold value ID are determined according to the mapping relation between the parent bandwidth threshold value and the parent bandwidth threshold value ID and the mapping relation between the child bandwidth threshold value and the child bandwidth threshold value ID.
And selecting the smaller value of the target parent bandwidth allowance and the target child bandwidth threshold as the target bandwidth threshold based on the target child bandwidth threshold and the target parent bandwidth threshold corresponding to the determined user equipment to be limited, and carrying out bandwidth limitation on any user equipment according to the target bandwidth threshold. The target parent bandwidth allowance 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 of the message sent by any user equipment is greater than the corresponding target bandwidth threshold, the secondary network equipment connected with the message can perform packet loss processing on the flow 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 device 103a, the user device 103b and the user device 103c, where the parent bandwidth threshold of the secondary network device 102a is 100Mbit/s, the sub-bandwidth threshold of the user device 103a is 20Mbit/s, and the sub-bandwidth threshold of the user device 103b is 50Mbit/s. If the secondary network device 102a has allocated 60Mbit/s in its parent bandwidth threshold to the user device 103c, for the user device 103a, the current target sub-bandwidth threshold is 20Mbit/s, the target parent bandwidth allowance is 40Mbit/s, and at this time, the target bandwidth threshold is smaller than the target parent bandwidth allowance, the target sub-bandwidth threshold 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 ue 103b, the target sub-bandwidth threshold is 50Mbit/s, the target parent bandwidth allowance is 40Mbit/s, and at this time, the target sub-bandwidth threshold is greater than the target parent bandwidth allowance, and the target parent bandwidth allowance is selected to be 40Mbit/s as the target bandwidth threshold of the ue 103b, if the ue 103b sends 30Mbit/s of traffic to the secondary network device 102a, the secondary network device 102a may forward all the traffic sent by the ue 103 b. By taking the smaller value of the sub-bandwidth threshold of the user equipment and the parent bandwidth allowance of the secondary network equipment connected with the sub-bandwidth threshold as the target bandwidth threshold for limiting the bandwidth of the user equipment, each user equipment can share the parent bandwidth of the secondary user equipment connected with the sub-bandwidth threshold under the limit of each sub-bandwidth threshold.
Further, each ue may occupy the parent bandwidth according to the principle of last arrival, or preset a priority for the IP address of each ue, so that when any ue is accessed, if its target child bandwidth threshold is greater than the target parent bandwidth threshold margin, it may determine, among other ues connected to the same secondary network device, that the priority is lower than the ue of the any ue, so as to reduce the actual bandwidth allocated to the determined ue, update the current target parent bandwidth margin, and determine the target bandwidth threshold of the any ue based on the updated target parent bandwidth margin. By setting the priority to the IP address of the user equipment, the user equipment with higher priority can be flexibly allocated with bandwidth resources according to the user demand.
In an embodiment, the sub-bandwidth threshold corresponding to each ue may be an interval number, and selecting a smaller value of the target parent bandwidth allowance and the target sub-bandwidth threshold as the target bandwidth threshold may include: when the target father bandwidth allowance is larger than the interval maximum value of the target child bandwidth threshold, selecting the interval maximum value as the target bandwidth threshold; when the target parent bandwidth allowance is larger than the minimum value of the interval of the target child bandwidth threshold and smaller than the maximum value of the interval of the target child bandwidth threshold, any value which is not larger than the target parent bandwidth allowance and not smaller than the minimum value of the interval 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 with 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, the sub-bandwidth threshold corresponding to the user device 103f is [10,15] Mbit/s, and if the message of the user device 103d firstly enters the secondary network device 102b, and at this time, the parent bandwidth allowance of the secondary network device 102b is 30Mbit/s, which is greater than the maximum value of the sub-bandwidth threshold [10,20] Mbit/s of the user device 102b, the maximum value of the interval 20Mbit/s is selected as the target bandwidth threshold of the user device 103 d; if the secondary network device 102b has allocated a parent bandwidth threshold of 20Mbit/s to the user device 103d, and then the message of the user device 103e also enters the secondary network device 102b, where the target parent bandwidth allowance of the secondary network device 102b is 10Mbit/s, and a minimum value of a range of 5Mbit/s greater than the child bandwidth threshold [5,15] Mbit/s of the user device 103e and less than a maximum value of 15Mbit/s of the range is greater than the target parent bandwidth allowance of 10Mbit/s and less than the minimum value of 5Mbit/s of the range is selected as the target bandwidth threshold of the user device 103 e; if the message from the ue 103f subsequently also enters the secondary network device 102b, where the parent bandwidth threshold 30Mbit/s of the secondary network device 102b has been allocated 20Mbit/s to the ue 103d for use, and 7Mbit/s is allocated to the ue 103e for use, where the target parent bandwidth margin is 3Mbit/s, and the minimum value of the interval of the child bandwidth threshold [10,15] Mbit/s of the ue 103f is smaller than the target parent bandwidth margin 3Mbit/s, then the target parent bandwidth margin 3Mbit/s is selected as the target bandwidth threshold of the ue 103 f.
On the basis, when the secondary network equipment distributes partial father bandwidth threshold values to other network equipment so that the target father bandwidth allowance is smaller than the maximum value of the interval of the target son bandwidth threshold values of any user equipment to be distributed currently, the actual bandwidth distributed to other user equipment connected with the same secondary network equipment with any user equipment can be reduced, and the target father bandwidth allowance 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 value 30Mbit/s to the user device 103d, when the target bandwidth threshold value is allocated to the user device 103e, the target parent bandwidth margin 10Mbit/s is smaller than the interval maximum value 15Mbit/s of the sub-bandwidth threshold values [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, for example, the target bandwidth threshold value 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 on the basis of this, the updated target bandwidth margin 15Mbit/s is compared with the sub-bandwidth threshold values [5,15] Mbit/s of the user device 103e to determine the target bandwidth threshold value of the user device 103 e.
Further, when the actual bandwidth allocated to other user equipment connected to the same secondary network equipment as any user equipment is reduced, the actual bandwidth allocated to each other user equipment connected to the same secondary network equipment as any user equipment can be reduced to the minimum value of the interval of the sub-bandwidth threshold value corresponding to each other; alternatively, the actual bandwidth allocated to each other user device connected to the same secondary network device as the any user device may be reduced by the same percentage; alternatively, each user device may be preset with a priority, and when the actual bandwidth allocated to other user devices is reduced, the actual bandwidth allocated to the user device with a relatively lower priority may be preferentially reduced. Based on the above example, after the secondary network device 102b has allocated 20Mbit/s of its parent bandwidth threshold value of 30Mbit/s to the user device 103d, and 7Mbit/s to the user device 103e, when the target bandwidth threshold value is allocated to the user device 103f, the actual bandwidth allocated to the user device 103d may be reduced to the minimum value of 10Mbit/s of its interval [10,20] Mbit/s, and the actual bandwidth allocated to the user device 103e may be reduced to the minimum value of 5Mbit/s of its interval [5,15] Mbit/s; alternatively, the same percentage may be reduced, for example, by reducing the actual bandwidth of the user device 103d by 10% along with the actual bandwidth of the user device 103e, such that the actual bandwidth of the user device 103d is reduced to 18Mbit/s and the actual bandwidth of the user device 103e is reduced to 6.3Mbit/s, it being understood that not all examples are shown herein and the application is not limited in this regard to the actual method of reducing bandwidth. By setting the sub-bandwidth threshold of the user equipment as the interval number, bandwidth threshold allocation can be more flexibly carried out for each user equipment when the bandwidth sharing is carried out on the father bandwidth, so that each user equipment can occupy more bandwidth resources when the father bandwidth resources are more abundant, the utilization rate of the bandwidth resources is improved, and the occupied bandwidth is timely adjusted when the father bandwidth resources are more scarce, thereby avoiding affecting the use of the father bandwidth resources by other user equipment.
Besides the above-mentioned three-level network structures of the first-level network device, the second-level network device and the user device, the network structure of the method for implementing the shared bandwidth disclosed in the present application may also be multi-level, for example, the method may be applied to the first-level network device, where the first-level network device is connected to at least one second-level network device, each second-level network device is connected to at least one third-level 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. Only the corresponding sub-bandwidth threshold, the primary bandwidth threshold and the secondary bandwidth threshold … … N-level bandwidth threshold are required to be established in the multi-level network architecture, and the available bandwidth of each level of network equipment can be limited according to the corresponding relation, so that the bandwidth of the final user equipment and the bandwidth of each level of network equipment corresponding to the final user equipment do not exceed the bandwidth limit of the final user equipment.
The technical scheme provided by the application can be seen that the bandwidth used by each user equipment when sharing the father bandwidth of the secondary network equipment can be flexibly limited by uniformly setting the son bandwidth threshold value used for limiting the bandwidth of each user equipment and the father bandwidth threshold value used for limiting the bandwidth of each secondary network equipment on the primary network equipment, so that the situation that the usage of other user equipment is influenced by excessive bandwidth resources occupied by individual user equipment is avoided. The following describes the network architecture shown in fig. 1 in detail with reference to fig. 3. Wherein fig. 3 is a multi-party interaction flow diagram illustrating a method of implementing shared bandwidth according to an exemplary embodiment of the present application. As shown in fig. 3, the interaction procedure between the user device 103a, the user device 103b, the secondary network device 102a, and the primary network device 101 includes the following steps:
in step 301, the user device 103a sends traffic to the secondary network device 102 a.
For example, the IP address of the user device 103a is 1.1.1.1, and 30Mbit/s of traffic is sent to the secondary network device 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 the pre-established correspondence between the IP address of each user device and the parent bandwidth threshold and the child bandwidth threshold, and in the embodiment of the present application, the correspondence between each user deep IP address and the parent bandwidth threshold and the child bandwidth threshold is stored by a tree structure storing the IP address and the threshold ID key value pair. For example, the parent bandwidth threshold ID corresponding to IP address 1.1.1.1 may be determined to be 1000 and the child bandwidth threshold ID to be 1001 by querying the tree structure. And according to a pre-established threshold ID:1000 and bandwidth threshold: 100Mbit/s, threshold ID:1001 and bandwidth threshold 20Mbit/s, threshold ID:1002 and 50Mbit/s, it may be determined that the parent bandwidth threshold corresponding to the ue 103a is 100Mbit/s, and the child bandwidth threshold is 20Mbit/s.
If the secondary network device 102a has allocated 60Mbit/s bandwidth to the user device 103c at this time, it may determine that the current parent bandwidth threshold margin is 40Mbit/s, compare the parent bandwidth margin with the child bandwidth threshold, and determine that the smaller child bandwidth threshold 20Mbit/s of the target parent bandwidth margin and the target child bandwidth threshold is the target bandwidth threshold of the user device 103a, i.e. the actual bandwidth allocated to the user device 103 a.
In step 303, the secondary network device 102a performs packet loss on the received traffic.
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 packet-losing the 10Mbit/s traffic which is larger than the 20Mbit/s actual bandwidth which can be allocated to the user equipment 103a in the 30Mbit/s traffic sent by 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 device 103b is 2.2.2.2, and 10Mbit/s of traffic is sent to the secondary network device 102 a.
In step 306, the secondary network device 102a determines the actual bandwidth that can be allocated to the user device 103 b.
As previously described, 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 child 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 and bandwidth threshold 20Mbit/s, threshold ID:1002 and 50Mbit/s, it may be determined that the parent bandwidth threshold corresponding to the ue 103b is 100Mbit/s, and the child bandwidth threshold is 50Mbit/s.
Since the secondary network device 102a has already allocated 60Mbit/s bandwidth to the user device 103c and 20Mbit/s bandwidth to the user device 103a at this time, it may determine that the current parent bandwidth threshold margin is 20Mbit/s, compare the parent bandwidth margin with the child bandwidth threshold, and determine that the smaller parent bandwidth threshold margin 20Mbit/s of the target parent bandwidth margin and the target child bandwidth threshold is the target bandwidth threshold of the user device 103b, i.e., the actual bandwidth 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 device 103b is smaller than the actual bandwidth 20Mbit/s that the secondary network device 102a can allocate to the user device 103b, the secondary network device 102a can forward all the traffic sent by the user device 103b to the primary network device 101.
