[0059] In order to make the objectives, technical solutions and advantages of the present application more clear, the present application will be further described in detail below with reference to the drawings and embodiments. Obviously, the specific embodiments described here only serve to explain the present application, and are only a part of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0061] Figure 1 The flow chart of one embodiment of the resource configuration method for the switch according to the present application is shown, which specifically includes the following steps:

[0062] Step 1: Obtain the first physical information between the intelligent control terminal and all switches, and the second physical information between any switch and other switches. The first physical information and the second physical information include the physical channel identifier of the directly connected and / or indirectly connected peer devices.

[0063] The above physical information refers to the physical connection information between devices.

[0064] A physical channel is the channel through which any switch transmits data with other devices (intelligent control terminals, switches, terminal devices, servers, etc.). Each switch establishes a point-to-point connection with a single device through a unique physical channel.

[0065] by Figure 2 For example, CT is an intelligent control terminal. CT communicates with switch S1 through physical channel 10 of switch S1. Switch S1 communicates with switch S3 through physical channel 1 of switch S3. Switch S3 communicates with switch S7 through physical channel 1 of switch S7. Part of the first physical information of the intelligent control terminal is (S1-10, S3-1, S7-1).

[0066] Step 2: Generate a physical topology map based on the first physical information and the second physical information.

[0067] Before configuring switch resources, it is essential to clarify the network's scale and structure. A clear understanding of the network structure allows for more effective planning and allocation of network resources, and helps administrators to intuitively see the connections and paths between devices.

[0068] Specifically, step 2 includes:

[0069] Step 21: Based on the first physical information, store the identification information of the intelligent control terminal in correspondence with the physical channel identifiers of all switches, and define it as the first correspondence. Based on the second physical information corresponding to any switch, store the identification information of any switch in correspondence with the physical channel identifiers of other switches, and define it as the second correspondence.

[0070] Step 22: Based on the first correspondence, perform data deduplication on all second correspondences, and construct the channel correspondence between each switch based on the data after data deduplication.

[0071] Step 23: Based on the channel correspondence, identify the topology between all switches and construct a topology table.

[0072] Step 24: Generate a physical topology diagram based on the topology structure table.

[0073] For example, the above-mentioned identification information is a unique identifier such as device serial number, MAC address, or device code.

[0074] by Figure 2 For example, the first correspondence is (S-CT, (S1-10, S3-1, S7-1, S6-1, S10-1, S2-1, S5-1, S9-1, S4-1, S8-1)), the second correspondence for switch S1 is (S-S1, (S3-1, S7-1, S6-1, S10-1, S2-1, S5-1, S9-1, S4-1, S8-1)), the second correspondence for switch S2 is (S-S2, (S1-2, S5-1, S9-1, S4-1, S8-1)), the second correspondence for switch S3 is (S-S3, (S1-1, S6-1, S10-1, S7-1)), and the second correspondence for switch S4 is (S... -S4, (S1-2, S2-6, S8-1)), the second correspondence of switch S5 is (S-S5, (S1-2, S2-5, S9-1)), the second correspondence of switch S6 is (S-S6, (S1-1, S3-4, S10-1)), the second correspondence of switch S7 is (S-S7, (S1-1, S3-3)), the second correspondence of switch S8 is (S-S8, (S1-2, S2-6, S4-6)), the second correspondence of switch S9 is (S-S9, (S1-2, S2-5, S5-4)), the second correspondence of switch S10 is (S-S2, (S1-1, S3-4, S6-2)).

[0075] Specifically, step 22 includes:

[0076] Step 221: Based on the first correspondence, traverse all second correspondences. When any second correspondence contains the same physical channel identifier as the first correspondence, remove the same physical channel identifier from the second correspondence.

[0077] Step 222: When there is only one physical channel identifier in any second correspondence, it is defined as a correspondence to be assigned. Extract the physical channel identifier in the correspondence to be assigned and define it as the first physical channel identifier.

[0078] Step 223: Extract the first identification information of the first switch to be matched corresponding to the correspondence to be assigned, extract the physical channel identifier belonging to the first switch to be matched from the first correspondence based on the first identification information, and define it as the second physical channel identifier.

[0079] Step 224: Extract the second switch to be matched corresponding to the first physical channel identifier, and construct the channel correspondence between the second switch to be matched and the first switch to be matched based on the first physical channel identifier and the second physical channel identifier.

[0080] Step 225: Remove the first physical channel identifier from all second correspondences, then return to step 222 until all physical channel identifiers in all second correspondences have been traversed.

[0081] by Figure 2 For example, after completing step 221, the second correspondence for switch S1 is empty, the second correspondence for switch S2 is (S-S2, (S1-2)), the second correspondence for switch S3 is (S-S3, (S1-1)), the second correspondence for switch S4 is (S-S4, (S1-2, S2-6)), the second correspondence for switch S5 is (S-S5, (S1-2, S2-5)), and the second correspondence for switch S6 is... The second correspondence for switch S7 is (S-S7, (S1-1, S3-3)), the second correspondence for switch S8 is (S-S8, (S1-2, S2-6, S4-6)), the second correspondence for switch S9 is (S-S9, (S1-2, S2-5, S5-4)), and the second correspondence for switch S10 is (S-S2, (S1-1, S3-4, S6-2)). In the second correspondence for switch S2, there is only one physical channel identifier S1-2, and the switch corresponding to this second correspondence is S2. In the first correspondence, the physical channel identifier belonging to switch S2 is S2-1. Therefore, the physical channel identifier S1-2 of switch S1 and the physical channel identifier S2-1 of switch S2 have a channel correspondence, meaning that switches S1 and S2 communicate via physical channels S1-2 and S2-1. The channel identifier S1-2 is then removed from all second correspondences.

[0082] After traversing all physical channel identifiers in all second correspondences, the channel correspondences between the switches are (S1-2, S2-1), (S1-1, S3-1), (S2-5, S5-1), (S2-6, S4-1), (S4-6, S8-1), (S5-4, S9-1), (S3-3, S7-1), (S3-4, S6-1), (S6-2, S10-1).

[0083] Specifically, step 23 includes:

[0084] Step 231: Identify the initial switch connected to the intelligent control terminal based on the channel correspondence. Then, starting from the initial switch, identify the topology between any switch and other switches in sequence.

[0085] Step 232, after identifying the topology between all switches, a structure table is generated for each switch, which includes the identification information of any switch, the identification information of the subordinate switch of any switch, and the number of switches located at the bottom layer directly connected and / or indirectly connected to any switch.

[0086] Step 233, generating a topology table based on all structure tables.

[0087] Exemplarily, the structure table corresponding to switch S1 is (S-S1, (S2, S3), 4), the structure table corresponding to switch S2 is (S-S2, (S4, S5), 2), the structure table corresponding to switch S3 is (S-S3, (S6, S7), 2), the structure table corresponding to switch S4 is (S-S4, (S8), 1), the structure table corresponding to switch S5 is (S-S5, (S9), 1), the structure table corresponding to switch S6 is (S-S6, (S10), 1), the structure table corresponding to switch S7 is (S-S7, (), 0), the structure table corresponding to switch S8 is (S-S8, (), 0), the structure table corresponding to switch S9 is (S-S9, (), 0), and the structure table corresponding to switch S10 is (S-S10, (), 0).

[0088] Exemplarily, when generating the physical topology diagram, there are 4 switches (S7, S8, S9, S10) located at the leaf node, and the topology network has a total of four layers. The total width of the topology diagram is set based on the preset width of one switch icon and the interval distance between two switches in the same layer, and the total height of the topology diagram is set based on the preset height of one switch icon and the interval distance between two layers of switches. Then, the above physical topology diagram is generated based on the total width, total height, and physical channel connection relationship between switches.

[0089] By generating the physical topology diagram, the network administrator can intuitively see the physical structure of the switch network, including the connection relationship and communication path between devices. By understanding the details of the physical connection, network resources can be more effectively planned and allocated, providing a basis for network optimization and switch resource configuration.

[0090] Step 3, acquiring a first value corresponding to a first performance indicator of any switch according to a first preset period, and calculating a second value corresponding to the first performance indicator of any switch based on the first weight coefficient of any switch, the second weight coefficient of all subordinate devices directly communicating with any switch, and the first value.

[0091] The first preset period is set according to the experience of those skilled in the art or according to the actual application scene, and the embodiments of the present application are not limited thereto. Exemplarily, the first preset period is 1 min.

[0092] Exemplarily, the first performance index is resource usage rate, CPU usage rate, etc. The subordinate devices in direct communication with the switch include switches, terminals, servers, etc.

[0093] Exemplarily, the calculation formula of the second value is:

[0094]

[0095] wherein R2 is the second value, R1 is the first value, W1 is the first weight coefficient, W2 i is the second weight coefficient of the ith subordinate device, i is a positive integer from 1 to I, and I is the total number of subordinate devices in direct communication with any switch.

[0096] Different weight coefficients are set for different devices (switches, servers and terminals), and the greater the weight coefficient, the higher the priority. It can be ensured that when the network is congested, the data flow with high weight coefficient can be processed preferentially to ensure the performance of critical business applications.

[0097] Specifically, step 3 further includes:

[0098] According to the second preset period, the amount of data flowing through any switch in the second preset time period is obtained, wherein the second preset period is an integer multiple of the first preset period.

[0099] The average value of the first performance index of any switch in the second preset time period is calculated.

[0100] The third value corresponding to the second performance index of any switch is obtained by dividing the amount of data by the average value.

[0101] The second preset period is set according to the experience of those skilled in the art or according to the actual application scene, and the embodiments of the present application are not limited thereto. Exemplarily, the second preset period is 1h.

[0102] Exemplarily, the second performance index is the total throughput of the switch, which is the maximum data flow that the switch can process in an ideal case.

[0103] Generally, the total throughput of a switch is given by the manufacturer, but in an actual switch network, the models, manufacturers, etc. of switches used are different, resulting in different total throughputs, efficiencies and capabilities of each switch when processing network traffic and data switching, and the values of the first performance indicators periodically obtained can only reflect the traffic and load at that time, and cannot comprehensively reflect the performance of the switch under different traffic and load conditions. In order to more accurately grasp the differences in efficiency and capability of the switch when processing network traffic and data switching, by analyzing the values of the first performance indicators of the switch and the amount of data flowing through the switch, the third values corresponding to the second performance indicators of each switch are periodically estimated, which can more effectively grasp the performance differences of the switch and improve the efficiency and accuracy of the configuration of switch resources.

[0104] Step 4, determining whether the second value is greater than or equal to the first preset value, if yes, defining any switch as a to-be-configured switch, and then automatically generating a configuration scheme for the to-be-configured switch based on the physical topology graph and the preset rule.

[0105] The first preset value is set according to the experience of those skilled in the art or according to the actual application scenario, and the embodiments of the present application are not limited thereto. Exemplarily, the first preset value is 80%.

[0106] When the second value is greater than or equal to the first preset value, it indicates that the load of the switch is high, and there is a risk of network congestion and device overload, and the data flowing through the switch needs to be shunted.

[0107] Specifically, step 4 includes:

[0108] Step 41, identifying all subordinate switches that are communicating with the to-be-configured switch, defining as first switches, and identifying all superior switches except the to-be-configured switch that can communicate with any first switch and have the same superior switch as the to-be-configured switch, defining as second switches.

[0109] Step 42, obtaining the second values corresponding to the first performance indicators of all second switches, and defining the second switches with second values less than or equal to the first preset value as third switches.

[0110] Step 43, extracting any third switch, calculating the fourth value corresponding to the second performance indicator of any third switch, and the calculation formula is:

[0111] CE4 = CE3 - CE3 x RL2,

[0112] Wherein, CE4 is the fourth value of any third switch, CE3 is the third value of any third switch, and RL2 is the second value of any third switch.

[0113] Step 44: Define the third switch whose fourth value is greater than or equal to the second preset value as a candidate switch, and identify the first switch whose second value is less than the first preset value and define it as the fourth switch.

[0114] Step 45: Construct a data forwarding path based on the candidate switch and the fourth switch, and then calculate the fifth value corresponding to the first performance index of the candidate switch on the data forwarding path.

[0115] Step 46: Determine whether the fifth value is less than the first preset value. If yes, use the data forwarding path as the configuration scheme. If no, return to step 45.

[0116] The second preset value is set based on the experience of those skilled in the art or according to the actual application scenario, and is not limited in this embodiment. For example, the second preset value is 6Gbps.

[0117] by Figure 3 The technical solution of this invention will be described using an example. The second value corresponding to the first performance indicator of switch S5 is 89%, and the third value corresponding to the second performance indicator is 20Gbps. The downstream switches communicating with switch S5 are switches S8, S9, and S10. Switch S4 is a switch connected to switch S8 and has the same upstream switch S2 as switch S5. When transferring the data flow from switch S8 to switch S4, the second value corresponding to the first performance indicator of switch S5 can be made less than a first preset value; in this case, switch S8 is defined as the fourth switch. The second value corresponding to the first performance indicator of switch S4 is 55% (less than the first preset value), the third value corresponding to the second performance indicator is 15Gbps, and the fourth value corresponding to the second performance indicator of switch S4 is 6.75. Since the fourth value of switch S4 is greater than the second preset value, switch S4 is selected as a candidate switch. A data forwarding path from S8 to S4 to S2 can be constructed. If the amount of data forwarded from switch S8 to switch S5 is 5Gbps, and the fifth value corresponding to the first performance indicator of switch S4 is 88.3% when forwarding data through this path, which is greater than the first preset value, then this data forwarding path cannot be used as a configuration scheme. If the amount of data forwarded from switch S8 to switch S5 is 1Gbps, and the fifth value corresponding to the first performance indicator of switch S4 is 61.7% when forwarding data through this path, which is less than the first preset value, then this data forwarding path can be used as a configuration scheme.

[0118] Specifically, step 46 also includes:

[0119] Step 47, if all data forwarding paths do not meet the condition of step 46, all upper-level switches capable of communicating with any first switch except the to-be-configured switch and the second switch and having the same connection point as the to-be-configured switch in the physical topology diagram are identified, defined as fifth switches.

[0120] Step 48, the fifth switch is taken as a new second switch, and then steps 42 to 44 are repeated.

[0121] Step 49, a new data forwarding path is built based on the candidate switch and the fourth switch, and then a sixth value corresponding to the first performance index of each switch between the fourth switch and the connection point on the new data forwarding path is calculated.
