Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method, an apparatus, and a device for checking a network topology connection.
Background
With the introduction of NFV (Network Function Virtualization) technology, a three-layer decoupled Network architecture gradually becomes a future Network trend. The software and hardware decoupling not only increases the networking flexibility, but also brings the integration and delivery test work of a large number of components. However, the integration process of the NFV network at present lacks a unified planning and unified platform, which results in complex and variable integration process and depends on the experience of integration personnel to a great extent. The number of iterations of integration increases and the probability of failure and error increases.
Due to the introduction of the next-generation network architecture, the access layer, the convergence layer and the core layer are not covered by the same manufacturer equipment any more, and the adaptation among multiple manufacturer equipment in a complex integrated environment is the most troublesome problem faced by a large-scale operator at present. And the integration efficiency is accelerated by adopting abundant automatic integration tools and continuous integration continuous delivery closed-loop chains, so that the flexibility of the network can be better exerted.
From the perspective of integrated delivery, the traditional delivery means cannot meet the requirements of operators, and the integrated delivery report of any manufacturer cannot test and cover all manufacturer devices in the resource pool, so that the current integrated delivery acceptance work is transferred to the operators to be completed. Although integrated vendors may provide partially automated assay collection tools, vendors are ill-equipped and do not guarantee that the test observation point will fully meet the operator's requirements. Therefore, operators should have an autonomously developed, neutral and automated integrated acceptance tool, and develop complete and efficient integrated acceptance from multiple aspects of hardware, network, software and the like.
The prior art has the following problems: in the past, the integrated delivery of the traditional network is basically completed by equipment manufacturers, because the decoupling is not realized from an access side, a convergence side and a core side, and the integrated delivery of the traditional network is basically different types of equipment of the same manufacturer. Each manufacturer has a CI/CD tool that is suitable for topology link inspection, and a report is delivered to the operator that is also output by the automation tool. However, after the NFV is introduced, the conventional network delivery means cannot meet the requirement, and since no CI/CD tool of any one vendor can cover all the vendors' devices in the environment, the work is handed over to the operator to complete. The checking of the connections between the switches of different vendors and the servers + switches of different vendors presents a major problem.

While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
As shown in fig. 1, an embodiment of the present invention provides a method for checking a network topology connection, including:
And 12, checking whether the topological connection is wrong or not according to the equipment information and equipment information in the connection information in a prestored information table.
In the embodiment of the invention, the device information of the opposite terminal device which has the topological connection with the first switch is obtained; and checking whether the topological connection is wrong or not according to the equipment information and equipment information in the connection information in a pre-stored information table. The method can realize the check of the network topology connection and has high check efficiency and correctness.
In an optional embodiment of the present invention, the step 12 may include:
step 121, if the device information is consistent with the device information in the connection information in the information table fed back by the pre-stored hardware integration manufacturer, determining that the topological connection between the first switch and the opposite-end device is correct, otherwise, determining that the topological connection between the first switch and the opposite-end device is incorrect.
Here, if the peer device is a second switch, and the host name of the second switch is consistent with the host name of the second switch in the connection information in the information table fed back by the pre-stored hardware integration manufacturer, it is determined that the topological connection between the first switch and the second switch is correct, and otherwise, it is determined that the topological connection between the first switch and the second switch is incorrect.
If the opposite-end equipment is a server and the MAC address of the server is consistent with the MAC address of the server in the connection information in the information table fed back by the pre-stored hardware integration manufacturer, the topological connection between the first switch and the server is determined to be correct, otherwise, the topological connection between the first switch and the server is determined to be wrong.
In the foregoing embodiment of the present invention, optionally, the device with a higher priority in the first switch and the peer device obtains device information of the peer device having a topological connection with the local device; and checking whether the topological connection is wrong or not according to the equipment information and equipment information in connection information in a pre-stored information table.
When the priority of the first switch is equal to the priority of the peer device, the checking method may further include: and step 13, carrying out duplication elimination operation on the check result of whether the topological connecting line is wrong or not.
Further, the method may further include: and step 14, transmitting the checking result of whether the topological connection line is wrong to a human-computer interface for displaying.
In the above embodiment of the present invention, after the device is delivered as a hard set, the operator performs network topology connection check. The requirement can be that actual topological connection is generated among the devices, the actually acquired connection is compared with the device connection information in a feedback table (LLD) delivered by a hard set manufacturer, the purpose of secondary test is achieved, and prompt warning information needs to be given once a link is found to be wrong.
As shown in fig. 2, a specific implementation flow of the foregoing embodiment includes:
and step 21, integrating data in an information table (LLD) fed back by a hardware integration manufacturer, and storing the table in a database form, so as to facilitate subsequent maintenance and search of the data.
And step 23, storing all the opposite-end device information directly connected with the first switch in a dictionary nesting list mode, wherein the storage mode is only an illustration mode, and other storage modes can be provided, the key of the dictionary is a device port number, the value is a dictionary in a list format, and the key is an opposite-end device hostname, an opposite-end MAC address and an opposite-end device port number respectively.
Here, the peer device is looked up in two cases, one is a switch (swicth) and the other is a server (server).
If the peer device is a switch, the type of the switch may include a TOR type switch, or an EOR type switch, and the link type is TOR + TOR, EOR + EOR, EOR + TOR. Finding an opposite-end switch in a database through the hostname, judging the type of the link, comparing the switch information of the opposite end found through detection with that stored in the database according to a preset checking sequence of equipment at two ends of the link, if the switch information is inconsistent with that stored in the database, checking the link by an error, and if a topological connection fed back by a hard set manufacturer is inconsistent with the actually checked link, returning an error alarm; if so, the link checks normal.
If the opposite-end device is a server, because the models of the network cards used in the servers of different manufacturers are different, and the degrees of LLDP supported by different network card types are different, taking X710 as an example, the LLDP is supported by the network card firmware of the network card itself, and the network card itself can interact with the opposite-end device with LLDP messages without depending on an upper operating system, but because the network card is self-sent, the hostname information is not carried in the LLDP messages, so that it is not feasible to use the hostname as the unique identifier of the network card.
Therefore, aiming at the link type of the server of the opposite terminal equipment, the information storage format of the opposite terminal equipment is modified, the hostname is abandoned as the unique identifier, the MAC address of the opposite terminal equipment is used as the unique identifier instead, and the link type of the server of the opposite terminal equipment is stored in a dictionary mode. When the opposite terminal is a server, the MAC address information of the opposite terminal equipment is read. For the two-layer switch, the MAC address of the device is unique, and for the server, each server may have multiple network cards, each network card corresponds to its own MAC address, so that it is necessary to find the corresponding network card MAC according to the obtained MAC address of the opposite terminal, determine which server the MAC address is on, and then search the database for the second time to determine whether there is a server found in the device directly connected to the device, if so, the link check is correct, if not, the link check is incorrect, and the topology connection fed back by the hard set manufacturer is inconsistent with the actually detected connection.
Since each link has two devices (i.e., a local device and an opposite device), if the link logs in each switch in sequence to obtain link information, a phenomenon that the same link is checked twice will inevitably occur, which may cause many redundant tests for link check.
If the level of the opposite terminal equipment is higher than that of the local terminal equipment, the opposite terminal equipment information is not acquired without checking the link, and the link information is acquired by the opposite terminal equipment;
if the level of the opposite terminal equipment is lower than that of the local terminal equipment, the link route is detected by the local terminal;
if the level of the opposite-end equipment is consistent with that of the local-end equipment (the condition of the same-level switch cascade is less), the link needs to be detected, and in order to avoid redundant data, the detected result of the link calls python grammar to perform deduplication operation.
And 25, comparing the link check condition in the step 24 with the database information stored in the step 21, returning the comparison results (Success and Failure) to the front end, and displaying the connection check result through the UI interface of the front end.
In the above embodiments of the present invention, the topology links are generated by packet interaction between the network devices and the server through the LLDP protocol. And classifying and storing each piece of opposite-end information searched by the switch by taking the equipment type, the application scene and the link type as models, so that the subsequent link state check is facilitated. According to the hierarchy of the network and the link type, the left end and the right end of the link are defined, the left end is a low-level switch, the rear end is a high-level switch, the high-level switch is logged in to check opposite-end information in a unified and specified mode, and redundant check of the link is prevented. The embodiment of the invention mainly aims at the hardware integration stage, and inspects the topological connecting lines among the EOR, the TOR and the server in the same resource pool, especially aims at the inspection of physical connecting lines rather than logical connecting lines, and is convenient, efficient and accurate in inspection result.
