Large cross-domain IP address rapid dynamic switching system and method

Abstract

The invention discloses a large cross-domain IP address rapid dynamic switching system and method. A large cross-domain IP address rapid dynamic switching network is formed by a plurality of local PPPoE routers, a plurality of tunnel servers and a plurality of virtual servers; a bidirectional tunnel is established between each local PPPoE router and each tunnel server; when a virtual server is in dynamic dial-up connection to the local PPPoE router, the local PPPoE router randomly selects a tunnel between the local PPPoE router and the tunnel server, and the tunnel server selects one of a plurality of local PPPoE router connections maintained by the tunnel server to obtain a public network IP address as a network proxy address of the virtual server. The method realizes proxy of an Internet access request of a dynamic VPS. the public network IP addresses at different geographic positions can be obtained by dialing on demand at a host at a fixed position, the cross-domain is wide, the dynamic VPS number has high elasticity and high scalability, and the dynamic VPS number can be expanded to hundreds and thousands without mutual influence.

Description

technical field [0001] The invention belongs to the field of network security and cloud computing, and in particular relates to a system and method for fast and dynamic switching of large cross-domain IP addresses. Background technique [0002] Generally speaking, servers or hosts have fixed IPs, including cloud servers, which are mainly used for building websites. IP is not just an address in the network, and the additional attributes of IP sometimes play a key role. For example, the geographical location of the IP address, some websites will restrict the access of foreign IPs, and only retain the access rights of local IPs; another example is the reputation of the IP address, the IP reputation is determined by whether it has sent spam, whether it has participated in web attacks, DDos, malicious activities and other factors. The worse the reputation of the IP, the greater the suspicion of engaging in malicious network activities. Therefore, the quality of the IP itself i...

Problems solved by technology

The capacity of all VPN IP pools is small, and the IP nodes are monopolized and relatively fixed by the VPN provider, and now the VPN network is easy to identify, and the probability of IP nodes being blocked is high

Traditional VPN basically builds network tunnels on demand, that is, every new dial-up request will build a new tunnel. When the frequency of dial-up requests increases, the method of building on-demand will consume a lot of network resources and occupy too much network resources. time

There are some methods to build network tunnels in advance, instead of building new tunnels every time a new dial-up is made, but when the number of dynamic VPSs increases, the tunnels between the local PPPoE router and the proxy server will also increase, and the local PPPoE router maintains many tunnel connections The cost will increase, limiting the number of dynamic VPS
