Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
A data center is a worldwide collaboration of specific equipment networks used to communicate, accelerate, expose, calculate, store data information over the internet infrastructure. The generation of data centers has led to the recognition of people from the quantitative, structural world into the uncertainty and unstructured world, which will gradually become part of the modern social infrastructure as well as traffic, network communications, and thus have a positive impact on many industries. In the application process of the data center, it may be necessary to acquire the interconnection topology of the network devices of the whole data center, for example, through an interface provided by a physical switch or a router, acquire the MAC addresses (Media Access Control Address, media access control addresses) of all network devices connected to the ports of the physical switch or the router, and then generate the topology relationship between the network devices according to the association relationship between the MAC addresses and the network devices. However, the interfaces provided by the current physical switches or routers are implemented based on the MAC forwarding table, and the MAC addresses of all network devices may not be obtained, so that the network topology generated finally is incomplete and has poor accuracy. The network topology generation method provided by the application can accurately generate the network topology of the data center.
Referring to fig. 1, fig. 1 is a flowchart of a network topology generating method according to an embodiment of the present application.
The network topology generation method provided by the embodiment of the application is applied to a data center and can comprise the following steps:
step S101: and acquiring first type identification information of each network device in the data center.
In practical application, the data center may first obtain first type identification information of each network device connected to the data center, where the first type identification information may reflect information of the network device and distinguish the network devices, and the type of the first type identification information may be determined according to actual needs, for example, the first type identification information may be SN (Serial Number) of the network device, etc.
In a specific application scenario, in order to facilitate obtaining the first type of identification information of the network device, the data center may collect the identification information of the network device through IPMI (Intelligent Platform Management Interface ). It should be noted that IPMI in the present application is an industry standard adopted for managing peripheral devices used in an enterprise system based on Intel architecture.
Step S102: and acquiring connection relations between each network device and other network devices, wherein the connection relations are determined based on the LLDP protocol.
In practical application, after the data center obtains the first type of identification information of each network device, only the identification information of a single network device can be obtained, but the connection relationship between the network devices cannot be obtained, so that in the application, the data center also needs to obtain the connection relationship, specifically, in the application, each network device determines the connection relationship related to itself based on the LLDP protocol, and the data center gathers the connection relationship between all the network devices uniformly.
It should be noted that, because the LLDP (Link Layer Discovery Protocol ) protocol provides a standard link layer discovery manner, the main capability, management address, device identifier, interface identifier and other information of the local device can be organized into different TLVs (types/lengths/values), and encapsulated in the LLD PDU (Link Layer Discovery Protocol Data Unit ) to be issued to the neighbor directly connected to the neighbor, and the neighbor receives the information and stores the neighbor in the form of a standard MIB (Management Information Base ) for the network management system to query and determine the communication status of the link, so that the network device in the present application can quickly and accurately determine the connection relationship related to the neighbor by means of the LLDP protocol.

Of course, the network device may directly generate the corresponding partial connection relationship according to the second type identification information, and the data center may aggregate the partial connection relationships to generate the connection relationship, which is not specifically limited herein.
