Description

Method and device for detecting three-layer interface IP address conflict
Technical Field

Background
The Internet Protocol (IP) address between networks is a number of computers on the Internet. It is normal for each networked computer to have an IP address to communicate properly. Comparing "computer" to "phone", the "IP address" is equivalent to "phone number". A "telephone number" cannot be in conflict (i.e., identical) and, similarly, an IP address cannot be in conflict (i.e., identical).
When data is transmitted between transmission devices, three-layer interfaces are required to be created, and the three-layer interfaces have various types, such as: a three-layer Virtual Local Area Network (VLAN) interface, a three-layer Ethernet port and a three-layer Ethernet sub-port. The three-layer interface of the transmission equipment needs to be configured with an IP address, the IP addresses of the three-layer interfaces of all the transmission equipment in a network consisting of the transmission equipment cannot conflict, and if the IP addresses conflict, data transmission failure in the network can be caused, so that normal network communication is influenced.
The network consisting of transmission devices is divided into two components: several private networks and public networks. A Private Network represents all Three-layer Virtual Private networks (Level Three Virtual Private networks abbreviated as L3 VPNs) belonging to a subnet; the public network represents a network other than all private networks. Or telephone, the private network is an internal telephone network of a company, and the public network is a telephone network outside the internal telephone networks of all companies. There cannot be a duplicate telephone number in the telephone network inside the company, nor in all telephone networks outside the company's internal telephone network. Similarly, there cannot be conflicting IP addresses in the private and public networks.

The preferred embodiment of the invention provides a method for simply, conveniently and efficiently detecting all kinds of three-layer interface IP address conflicts in the whole network. Fig. 5 is a flowchart of a method for detecting IP address conflicts of all kinds of three-layer interfaces of the whole network according to an alternative embodiment of the present invention, and as shown in fig. 5, the flowchart includes the following steps:
step S502: creating a table 1 in a database of a network manager, and storing all kinds of three-layer interfaces and IP addresses of the three-layer interfaces;
table 1 corresponds to the first predetermined table, which is used for the convenience of the following query.
Step S504: creating a table 2 in a database of a network manager, and storing the three-layer interfaces belonging to the public network and the IP addresses of the three-layer interfaces;
table 2 corresponds to the second preset table, and an index is created in the IP address column of the three-layer interface of the table, and the index is used to complete the quick search of the conflicting IP addresses.
Step S506: inquiring all L3 VPNs;
the query result comprises the name of the subnet to which the L3VPN belongs and a three-layer interface included by the L3 VPN. All L3 VPNs with the same subnet name are a private network. Generating two groups of data according to the query result:
a) the private network name and the three-layer interface set of the private network are stored in a mapping;
b) the three-tier interfaces of all private networks are stored in one set.
Step S508: inquiring IP addresses of three-layer interfaces and three-layer interfaces of all network elements;
wherein, the query result is filtered by using the data b) of the step S506, and the three-layer interface in the data b) not belonging to the step S506 belongs to the three-layer interface of the public network. The IP addresses of the three-layer interface of the public network and the three-layer interface thereof are stored in the table created in step S504.
Step S510: performing IP address conflict detection on the data;

step b: the IP addresses are traversed and conflicting IP addresses are found. And recording the private network name, the three-layer interfaces with IP address conflict and the IP addresses of the three-layer interfaces.
Step S512: and executing a query statement on the table created in the step S504 in the database, finding out the IP addresses with conflicts, and recording the three-layer interfaces with the conflicts of the IP addresses and the IP addresses of the three-layer interfaces.
Step S514: the table created in step S504 is deleted from the database.
Step S516: recording three-layer interfaces with confliction of IP addresses in the private network and the public network and IP addresses of the three-layer interfaces, and presenting a detection result.
The network management of the related art only provides collision detection in the respective configuration functions of the three-layer interfaces of various types, but some types of three-layer interface configuration functions do not provide collision detection yet. Therefore, in the related art, it can only be guaranteed to the minimum extent that the IP addresses of some kinds of three-layer interfaces do not conflict, and it cannot be guaranteed that the IP addresses of all kinds of three-layer interfaces in the whole network do not conflict. If the IP address conflicts, the problem cannot be found immediately, and the problem can only be found by a manual checking mode of a configurator when the data transmission has problems, that is, the mode in the related art is inefficient and the IP address with conflicts cannot be found immediately. By the optional embodiment of the invention, all kinds of three-layer interface IP address conflicts of the whole network (public network and all private networks) can be rapidly detected, and the detection result is presented to the user, so that the user is helped to rapidly locate the problem, and a series of problems caused by the IP address conflicts are avoided.
