Method and apparatus for automatic networking by multi-port equipment

Abstract

The embodiment of the invention discloses an automatically networking method of a multi-network mouth device, which comprises the following steps: the multi-network mouth device obtains the only IP address of the whole network, and the multi-network mouth device runs on a physical interface to negotiate protocols when establishing connection with an end-to-end equipment, which negotiates with the end-to-end equipment to obtain virtual logic interface, and two devices are led to mutually communicate through operating the communication protocol on the virtual logic interface. The embodiment of the invention discloses a multi-network mouth device. The multi-network mouth device can mutually communicate under implied circumstance, which does not need to manually allocate the IP address of each interface, greatly lowers maintenance cost of network equipment, and further reduces the possibility of manual allocated mistakes, in addition, a plurality of network mouths of one device use one IP address, and address resources are further saved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for automatic networking of multi-network port devices. Background technique [0002] In the Transmission Control Protocol / Internet Protocol (TCP / IP) architecture, the link layer is used to shield the differences of various physical interfaces and provide a unified data transmission service to the network layer. There are two types of the most common physical interfaces: one is a point-to-point interface, where only two directly connected devices communicate with each other, such as an optical port in an optical network device. The other is the broadcast interface. One device sends data, and multiple devices in the same LAN can receive the data, such as Ethernet. On the point-to-point interface, the link layer protocol runs Point to Point Protocol (PPP); on the Ethernet, the link layer generally runs the Ethernet protocol. Above the link layer, the ne...

Problems solved by technology

Because the central network management cannot access the device before the IP address is correctly configured, it is necessary to manually set the IP address of each interface locally on the device, and the maintenance cost is high

Although a single interface does not occupy many resources, when there are multiple interfaces, for example, for an optical network device with dozens or even hundreds of interfaces, each interface occupies the address of a network segment, which will cause great impact on address resources. great waste
