NETWORK CONNECTION DEVICE AND LOCAL AREA NETWORK ESTABLISHMENT SYSTEM

摘要

Disclosed are a network connection device and a local area network establishment system. The network connection device comprises: N+1 network ports, N of which connected to N network devices separately and the other one of which connected to a computer control end; a hand-off switch connected to the N+1 network ports separately; a singlechip used for computing the network ports to be on in the N network ports according to the received hand-off signal, and for connecting the other network port to the network ports to be on by controlling the hand-off switch. With the technical solution of the present invention implementation, comparing with the prior art, there is no need to set different IP address for each network device by special software in the local area network establishment, and hence it is more simple and convenient.
