The ASN Security Linkage solution of the flying fish star is a distributed security control network architecture composed of multi-Wan firewall Broadband Router VR + anti-attack security linkage switch VS. It is a system that securely reaches any intranet information point. As an intranet hazard analysis role, VR routers can discover, locate, analyze, and issue effective instructions to the performer VS vswitch; at the same time, when the VS switch receives the command, it immediately takes relevant measures to deliver the green and safe data on the Intranet to the vrovr VR, which can ensure the long-term stable operation of the network, according to Internet cafe customers, the ASN Security Linkage solution is a zero-maintenance network architecture, which is very effective in defending against attacks similar to the ghost and shadow viruses.

Economic: you only need a vrovr VR and a central switch VS 5324GT to ensure Intranet security.

L solution 3-trunk link linkage solution (suitable for small-sized Internet cafes with 80 or less servers ):

VOLANS-4900GP (other models allowed) + VS-5124GT (bound to 80 hosts)

Advantages:

Security: 100% defends against attacks caused by ghost and shadow viruses, which can be fundamentally solved for Intranet ARP and DDOS attacks.

Economic: you only need to add cost-effective VS-5124GT in the network to achieve zero maintenance network.
