Local area network system and interconnection method for internal controller system thereof

Abstract

The embodiment of the invention discloses a local area network system and an interconnection method for an internal controller system thereof. The method comprises the steps as follows: the controller system acquires an IP address of a buddy system in a local area network; the controller determines an idle IP address in a predetermined IP address network segment according to the acquired IP address of the buddy system; the controller system selects the idle IP address for itself; and the controller system uses the own IP address to build a connection with the buddy system in the local area network. According to the method provided by the invention, the problems that cost is increased due to the fact that a currently used DHCP server distributes the IP address for the control system group, and the controller system cannot be conveniently and flexibly added into and quitted from the Internet if a DHCP service is opened on the controller system to serve as a DHCP server can be effectively solved. The cost of the DHCP server is saved, and each controller system can be flexibly added into and quitted from the Internet.

Description

technical field [0001] The invention relates to the field of communication and interconnection, in particular to a method for interconnecting a local area network system and its internal controller systems. Background technique [0002] With the development of information technology, the exchange of electronic information data has become the main form of information transmission, and the sharing of information resources is becoming more and more important. Therefore, multiple storage devices or multiple controllers in one storage device often need to be connected to each other to synchronize information. In the case of interconnection between devices using the network, each device system or controller system needs to have an IP address, and the IP addresses between each other cannot conflict. [0003] At present, the most widely used IP allocation method is DHCP (Dynamic Host Configuration Protocol) dynamic allocation method, which uses the DHCP service to allocate IP addre...

AI Technical Summary

Problems solved by technology

[0004] If multiple storage devices or multiple controller systems in one storage device are interconnected and use a DHCP server to assign IP addresses to them, the DHCP server needs to be added, which increases the cost; if the DHCP service is enabled on a controller system As a DHCP server, these systems will no longer be peer-to-peer, and the controller system that enables the DHCP service cannot flexibly join and exit the Internet
