Background

With the maturity and high-speed development of network technology and internet technology, more and more enterprises and public institutions start to build networks to realize office automation and share information of the internet. However, the security problem is also highlighted, and memory network companies propose a solution for achieving internal and external network isolation by combining switches, firewalls and switches according to the characteristics of the e-government network. The first scheme is as follows: the switch realizes the physical isolation of the internal network and the external network, and the network system consists of two relatively independent and mutually associated parts, namely an internal local area network and an external internet, and both adopt a star topology structure and a 100M switching type fast Ethernet technology. There is no physical connection between the intranet and the extranet, so that an intruder from the Internet cannot enter the intranet from the extranet through a computer, the security of important data of the intranet is guaranteed most effectively, and the intranet and the external Internet are physically isolated. Scheme II: prevent that hot wall and switch combine, realize the intranet and extranet and keep apart, VLAN keeps apart the intranet and extranet: the method is characterized in that multiple services exist in the e-government network, unified interconnection of multiple networks is realized, meanwhile, the safety of each network is guaranteed, data leakage and tampering are avoided through means such as encryption and signature on an application layer, VLAN technology is adopted on a local area network switch, devices of different service networks are placed in different VLANs for physical isolation, and unnecessary random access among the networks is thoroughly avoided. Among the techniques for implementing VLANs, the most mature and secure VLAN based ethernet switch ports (ieee802.1q) is the firewall access control guarantee.

For example, application No.: 201610470833.3 the invention discloses a switch and a switch system, belonging to the switch design field.
