Network backup device and network system with same

Abstract

Provided are a network backup device and a network system with the same. According to an embodiment, the network backup device includes a first connector configured to connect with one or more ports of a first network equipment, a second connector configured to connect with one or more second network equipment, a third connector configured to connect with a third network equipment, a switching module configured to aggregate data transmitted from the second connector, transfer the aggregated data to the third connector, and distribute data transmitted from the third connector to the second connector, and a switch configured to, in response to a fault occurring in a port of the first network equipment, switch from a connection between the second connector and the faulty port of the first network equipment to a connection between the second connector and the switching module.

Description

Technical field [0001] The embodiments of the present invention relate to a network technology, and more particularly to a network backup device capable of simplifying and minimizing the configuration of backup network equipment and a network system provided with the network backup device. Background technique [0002] Recently, with the development of short-distance communication network and Internet technology, most of the business in enterprises or public institutions is completed by computers. Therefore, in order to share and exchange data between employees, there is an increasing trend of connecting personal computers to each other to build a network environment. In addition, since the automation of production equipment is built in the industrial field, it is common to control production equipment through a network. [0003] figure 1 It is a diagram showing the configuration of a general network system. [0004] Reference figure 1 , The network system includes: a server group ...

AI Technical Summary

Problems solved by technology

[0013] And, the network backup device 600 switches a certain network switch that fails in the n network switches 401 to the backup network switch 405, so when a plurality of network switches fail, it is necessary to set the specific network switch for which network switch is switched to the backup network switch 405. priority order, and it is necessary to compare the priority orders of the failed network switches with each other, so there is a problem that the backup process by the network backup device 600 is complicated

[0014] Moreover, in the prior art, in order not to waste the ports of the network backup device 600 according to the number of network switches 401, it is necessary to manufacture the network backup device 600 with various numbers of ports, which is the cause of increased manufacturing costs.
