Description

TECHNICAL FIELD

[0001] The present application relates to the field of equal-cost multi-path routing, and in particular to a method and device for testing multi-path ECMP load sharing, and a medium. BACKGROUND

[0002] Equal-cost multi-path (ECMP) is a network environment in which multiple different links reach the same destination address. If a traditional routing technique is used, data packets sent to the destination address can only use one of the links, and the other links are in a backup state or invalid state. In a dynamic routing environment, the switching between the links requires a certain amount of time. An equal-cost multi-path routing protocol can use multiple links simultaneously in this network environment, thereby increasing the transmission bandwidth and enabling data transmission to be backed up on the failed link without delay and loss of packets.

[0003] A conventional switch supports at most 6 ECMP load sharing links, while a new type of switch project has implemented 32 links. A conventional testing method is to build 32 physical links, configure IP addresses on each link, add all the IP addresses to the same OSPF domain to establish a route, and then check the port statistics on each link to determine whether load sharing is performed on the 32 links.

[0004] This method requires a large amount of material for environment setup, and the setup is relatively complex. In addition, the configuration of a large number of IP addresses on the ports is also troublesome, thereby greatly increasing the testing complexity. SUMMARY

[0005] To solve the above problems, the present application provides a method and device for testing multi-path ECMP load sharing, and a medium. The method comprises the following steps:

[0006] Confirming a test task, determining a main test device and an auxiliary test device according to the test task, building a test environment according to the test task, the test environment comprising a single physical link, a virtual local area network, and a logical interface corresponding to the virtual local area network, binding the logical interface through access control list (ACL) technology on the auxiliary test device to obtain a number of messages, and determining whether load sharing is performed on the load sharing links according to the number of messages.

[0007] In one example, the step of building the test environment according to the test task comprises the following steps: connecting the main test device and the auxiliary test device with a single physical link, and configuring a first test instrument port and a second test instrument port capable of sending IP changed traffic, wherein the first test instrument port is connected to the main test device, and the second test instrument port is connected to the auxiliary test device.

[0008] In one example, it is characterized in that the configuration can be used to send the first tester port and the second tester port of IP change traffic, and the method further comprises: adding a plurality of virtual local area networks on the single physical link between the master test device and the auxiliary test device; the number of virtual local area networks is the same as the number of load sharing links; creating a logical interface corresponding to the plurality of virtual local area networks, and configuring a corresponding plurality of first IP addresses; configuring different mac addresses under each logical interface of the master test device.

[0009] In one example, after configuring different mac addresses under each logical interface of the master test device, the method further comprises: creating a virtual local area network for the first tester port and the port adjacent to the master test device, and the second tester port and the port adjacent to the auxiliary test device, and creating a corresponding logical interface and configuring a second IP address; adding the first IP address and the second IP address to the same OSPF domain.

[0010] In one example, the master test device and the auxiliary test device are the same device.

[0011] In one example, when the logical interface is bound on the auxiliary test device through access control list ACL technology, the statistical key is set to the mac address corresponding to the logical port.

[0012] In one example, the test environment is built according to the test task, specifically comprising: determining an environment building script in a database according to the test task; and configuring the test environment through the environment building script.

[0013] The application also provides a test device for multiple ECMP load sharing, comprising: a task confirmation module for confirming a test task and determining a master test device and an auxiliary test device according to the test task; an environment building module for building a test environment according to the test task, the test environment comprising a single physical link, a virtual local area network and a logical interface corresponding to the virtual local area network; a packet obtaining module for binding the logical interface on the auxiliary test device through access control list ACL technology to obtain a number of packets; and a judgment module for judging whether load sharing links are load shared according to the number of packets.

[0014] The application further provides a test device for multi-path ECMP load sharing, comprising: at least one processor; and a memory connected with the at least one processor; wherein the memory stores instructions executable by the at least one processor, and the instructions are executed by the at least one processor to enable the at least one processor to perform the following: confirming a test task, determining a main test device and an auxiliary test device according to the test task; according to the test task, building a test environment, wherein the test environment comprises a single physical link, a virtual local area network and a logical interface corresponding to the virtual local area network; binding the logical interface by using an access control list (ACL) technology on the auxiliary test device to obtain a number of messages; and judging whether load sharing is performed on the load sharing link according to the number of messages.

[0015] The application further provides a non-volatile computer storage medium storing computer executable instructions, which are configured to: confirm a test task, determine a main test device and an auxiliary test device according to the test task; according to the test task, build a test environment, wherein the test environment comprises a single physical link, a virtual local area network and a logical interface corresponding to the virtual local area network; bind the logical interface by using an access control list (ACL) technology on the auxiliary test device to obtain a number of messages; and judge whether load sharing is performed on the load sharing link according to the number of messages.

[0016] The method provided by the application can bring the following beneficial effects: the application uses a physical link to replace a plurality of physical links, and the environment building is simpler. Moreover, the application is not limited by the number of load sharing links supported by a switch. The more load sharing links supported by the switch, the more efficient the method is, and the method has strong scalability. When a physical link is added to a plurality of VLANs and a VLANif is created and an IP address is configured, and when a plurality of ACLs are configured on the Device2 and are bound, a script can be directly used to brush the configurations, thereby saving the time of manual input.

[0023] In order to make the objectives, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described in detail below with reference to the embodiments of the present application and corresponding drawings. Obviously, the described embodiments are only some 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 fall within the scope of protection of the present application.

[0024] As shown in Figure 1 , the traditional test method is to build 32 physical links, configure IP addresses on each link, add all IP addresses to the same OSPF domain to punch through the route, and then check the port statistics on each link to determine whether load sharing is performed on the 32 links. This method requires a large amount of material for environment construction, and is relatively complex to build. At the same time, the IP address configuration of a large number of ports is also very troublesome, so the test complexity is greatly improved.

[0025] The technical solutions provided by the embodiments of the present application will be described in detail below with reference to the drawings.

[0026] Figure 1 A flowchart of a test method for multi-path ECMP load sharing provided by one or more embodiments of the present specification is shown. The flowchart can be executed by a computing device in the corresponding field, and some input parameters or intermediate results in the flowchart allow manual intervention to adjust to help improve accuracy.

[0027] The implementation of the analysis method related to the embodiments of the present application can be a terminal device or a server, and the present application does not make special limitations thereon. For the convenience of understanding and description, the following embodiments are described in detail with the server as an example.

[0028] It should be noted that the server can be a separate device, or a system composed of multiple devices, i.e., a distributed server, and the present application does not make specific limitations thereon.

[0029] As shown in Figure 1 , the embodiments of the present application provide a test method for multi-path ECMP load sharing, which comprises:

[0030] S101: Confirm the test task, and determine the main test device and the auxiliary test device according to the test task.

[0031] Firstly, the test task published by the staff needs to be confirmed, and the main test device and the auxiliary test device in the test task are determined according to the test task requirements published by the staff.

[0032] S102: According to the test task, a test environment is built, which includes a single physical link, a virtual local area network, and a logical interface corresponding to the virtual local area network.

[0033] Before testing, the test environment needs to be built according to the test requirements of the test task, and here the test environment includes a single physical link, a virtual local area network, and a corresponding logical interface.

[0034] As shown in Figure 2 In one embodiment, when building the test environment, first, a physical link (such as if2 and if3) is used to connect the main test device Device 1 and the auxiliary test device Device 2; then the first tester port (Tc A) and the second tester port (Tc B) capable of sending IP change traffic are configured, and the first tester port is connected to the main test device, and the second tester port is connected to the auxiliary test device.

[0035] In one embodiment, after configuring the tester port, a plurality of virtual local area networks need to be added on the single physical link between the main test device and the auxiliary test device; here the number of virtual local area networks is the same as the number of load sharing links. At the same time, logical interfaces corresponding to the plurality of virtual local area networks are created, and a plurality of first IP addresses are configured. In addition, different mac addresses are configured under each logical interface of the main test device.

[0036] In one embodiment, after configuring the mac address of the logical interface, a virtual local area network needs to be created for the port adjacent to the main test device (such as if1) of the first tester port, and the port adjacent to the auxiliary test device (such as if4) of the second tester port, and a corresponding logical interface is created and a second IP address is configured; the first IP address and the second IP address are added to the same OSPF domain to pass through the route.

[0037] In one embodiment, the main test device and the auxiliary test device need to be the same device, so that the limitation of the ECMP load sharing link remains consistent, which is conducive to establishing the number of virtual links that meet the test requirements.

[0038] S103: Bind the logical interface on the auxiliary test device through access control list (ACL) technology to obtain the number of messages.

[0039] By using Access Control List (ACL) technology on the auxiliary testing device, the number of packets received by each logical interface can be viewed.

[0040] In one embodiment, when binding the logical interface, the statistical keyword is set to the MAC address corresponding to the logical port.

[0041] S104: Determine whether load sharing is performed on the load-sharing link based on the number of messages.

[0042] The number of packets corresponding to the logical interface can be used to determine whether load sharing has been implemented on the load-sharing link.

[0043] In one embodiment, when setting up a test environment, the configuration can be refreshed through a pre-set script, thereby saving manual time. In this case, the pre-written environment setup script needs to be determined by summarizing the test requirements of the test task in the database, and then the test environment is configured through the environment setup script.

[0044] The aforementioned environment setup script can be pre-stored in the computer device's storage. When a test environment needs to be set up, the computer device can select the environment setup script from the storage device. Alternatively, the computer device can also obtain the environment setup script from other external devices. For example, the environment setup script can be stored in the cloud, and when a test environment needs to be set up, the computer device can retrieve the environment setup script from the cloud. This embodiment does not limit the method of obtaining the environment setup script.

[0045] By using a single physical link instead of multiple physical links, environment setup is simpler. Furthermore, it is not limited by the number of load-sharing links supported by the switch. The more ECMP load-sharing links supported by the switch, the more efficient this method becomes, exhibiting strong scalability. Additionally, when adding multiple VLANs to the physical link, creating VLANIFs and configuring IP addresses, or configuring and binding multiple ACLs on Device 2, the configuration can be directly updated using scripts, saving manual time.

[0046] like Figure 4 As shown in the figure, this application embodiment also provides a test device for multiple ECMP load sharing, including:

[0047] Task confirmation module 401 confirms the test task and determines the main test device and auxiliary test device based on the test task.

[0048] Environment setup module 402 sets up a test environment according to the test task. The test environment includes a single physical link, a virtual local area network (VLAN), and the logical interface corresponding to the VLAN.

[0049] The message obtaining module 403 binds the logical interface through access control list (ACL) technology on the secondary measurement device to obtain the number of messages.

[0050] The judging module 404 judges whether the load sharing link is load shared according to the number of messages.

[0051] As shown in the figure, Figure 5 The embodiment of the application further provides a test device for multiple ECMP load sharing, comprising:

[0052] at least one processor; and

[0053] a memory in communication connection with the at least one processor; wherein

[0056] The embodiment of the application further provides a non-volatile computer storage medium, which stores computer executable instructions, and the computer executable instructions are set to:

[0057] confirm a test task, determine a primary measurement device and a secondary measurement device according to the test task, build a test environment according to the test task, the test environment comprising a single physical link, a virtual local area network and a logical interface corresponding to the virtual local area network, bind the logical interface through access control list (ACL) technology on the secondary measurement device to obtain the number of messages, and judge whether the load sharing link is load shared according to the number of messages.
