Method and system for extending network interfaces, and method for receiving and sending message

Abstract

The invention discloses a method and a system for extending network interfaces, and a method for receiving and sending a message. The method for extending the network interfaces comprises a step of arranging extension ports of switch chips in sequence and storing interface numbers, carrying out registration according to virtual network card equipment, and setting interface names displayed to the external; a step of setting corresponding relations between the extension ports and upper link ports of the extension ports and network interfaces of network equipment according to the interface numbers, and storing the corresponding relations; a step of mapping the extension ports with corresponding VLANs of the virtual network card equipment according to the interface names, mapping the upper link ports of the extension ports, the network interfaces and the VLANs according to the corresponding relations, and storing a VLAN-ID of each VLAN; and a step of each switch chip configuring a double-label mode according to the VLAN-ID and arranging an outer layer label. According to the invention, requirements for the density of network interfaces of different pieces of network equipment can be met, the extension port of each switch chip is an independent internet access, and independent configuration issuing and message receiving and sending can be achieved.

Description

technical field [0001] The invention relates to the field of network extension, in particular to a method and system for extending a network interface, and a method for sending and receiving messages. Background technique [0002] In today's digital communication era, the interface density requirements of network equipment are getting higher and higher, and the number and types of external networks connected to network equipment such as firewalls and switches are increasing. If all network devices have independent network ports led out by network cards to connect to the external network, the total cost of network devices will become very high. Therefore, most network devices in the prior art expand network interfaces through switching chips. [0003] In the prior art, when expanding the network interface through the switching chip, first dynamically divide the virtual local area network (Virtual Local Area Network, VLAN), and then add the interface of the network device to t...

Problems solved by technology

Every time a packet is sent and received through an interface, operations such as VLAN division and interface configuration are required. At the same time, the extended network interface is not an independent interface from the outside, and data such as IP and route cannot be directly configured. The process is complicated and the operation is troublesome.
