Description

Reverse proxy system
Technical Field
The present invention relates to reverse proxy technology, and in particular, to a reverse proxy system.
Background
At present, the traditional international IP accesses to the domestic routing site, and needs to route back from the foreign pocket, so that time delay and packet loss can be multiplied, qoS quality of the network can not be ensured, and normal production environment of users is affected. The re-arrangement of the optical drill is needed for re-finding one provider, and the defects of increased investment, longer opening period and the like are overcome.
Disclosure of Invention
It is an object of the present invention to provide a reverse proxy system that overcomes the above-mentioned drawbacks of the prior art.
The aim of the invention can be achieved by the following technical scheme:
the reverse proxy system comprises a user end, an international gateway, a reverse proxy node and a domestic operator network which are connected in sequence, wherein the reverse proxy node is also connected with the international network; the reverse proxy node comprises a proxy server and a Web server connected with the proxy server.
Preferably, the reverse proxy node extracts the routing information of the domestic operator network through a BGP dynamic routing analysis method and a redirection technology and reversely proxies the routing information to the domestic operator network.
Preferably, the reverse proxy node accesses the international network through default route matching of the international gateway.
Preferably, the reverse proxy service node further includes DNS servers, the number of the proxy servers and the number of the Web servers are not less than two, the DNS servers are connected with all proxy servers, each proxy server is connected with all Web servers, the DNS servers are connected with the international gateway, and the Web servers are respectively connected with the domestic operator network and the international network.
Preferably, the number of the proxy servers and the Web servers is 2.
Preferably, the proxy server is a Squid proxy server or a nmginx proxy server.
Preferably, the proxy server is connected with a cache server.
Preferably, the home operator network comprises one of a china telecommunication network, a china communication network, a china mobile network.
Compared with the prior art, the invention has the following advantages:
1. the reverse proxy node realizes that the international IP access domestic route is reversely proxy to the IP resource of the domestic operator, thereby improving the QoS quality of the international IP access domestic route IP.
2. The anti-proxy node distributes the request of the user side to one proxy server for processing through a DNS polling technology, if the proxy server caches the request resource of the user, the requested resource is directly returned to the user, otherwise, the proxy server sends the request which is not cached to the neighbor proxy server according to the configuration rule, so that the load of a background Web server is reduced, and the performance and the safety of the anti-proxy node are improved.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
The drawing is marked: 1. the system comprises a user, an international gateway, a reverse proxy node, a domestic operator network, a national operator network, a proxy server, a Web server, a DNS server and a Web server.
Detailed Description
The invention will now be described in detail with reference to the drawings and specific examples. The present embodiment is implemented on the premise of the technical scheme of the present invention, and a detailed implementation manner and a specific operation process are given, but the protection scope of the present invention is not limited to the following examples.
Examples
As shown in fig. 1, a reverse proxy system is used for reverse proxy of a user using foreign IP to domestic routing, and includes a user terminal 1, an international gateway office 2, a reverse proxy node 3 and a domestic operator network 4 which are sequentially connected, wherein the reverse proxy node 3 is also connected to an international network 5. The user terminal 1 comprises a network access router.
The reverse proxy service node includes DNS servers 8, proxy servers 6 and Web servers 7, the number of proxy servers 6 and Web servers 7 is not less than two, DNS servers 8 are connected to all proxy servers 6, and each proxy server 6 is connected to all Web servers 7. The DNS server 8 is connected to the international gateway 2, and the web server 7 is connected to the national operator network 4 and the international network 5, respectively. The DNS server 8 distributes the request of the client 1 to one proxy server 6 for processing through a polling mechanism, if the proxy server 6 caches the request resource of the user, the requested resource is directly returned to the client 1, otherwise, the proxy server 6 sends the request without caching to the neighbor proxy server 6 according to the configured rule, thereby not only reducing the load of the background Web server 7, but also improving the performance and security of the reverse proxy node 3.
In the present embodiment, the number of proxy servers 6 and Web servers 7 is 2. In order to speed up the response of the proxy server 6, a caching technique may be used, in which case the proxy server 6 may be connected to a caching server. In this embodiment, the proxy server 6 is a Squid proxy server.
The reverse proxy node 3 extracts the routing information of the domestic operator network 4 through the BGP dynamic routing analysis method and the redirection technology and reversely proxies the routing information to the domestic operator network 4, and accesses the international network 5 through the default routing matching of the international gateway 2, so that the user accesses the domestic routing and the international network 5 faster.
The specific implementation method of the system comprises the following steps:
1. the network access router of the user terminal 1 is configured according to a policy route, and the IP access of the user terminal 1 is directed to the international gateway 2 through the policy route;
2. establishing BGP dynamic route acquisition in the international gateway 2, providing route table information for subsequent reverse proxy, and transmitting the received reverse proxy from domestic IP route to domestic IP;
3. the international route is matched to the international export according to the default route of the international gateway office 2, and since the user IP is international, the route IP of the IP access home operator is reversely proxied to the home IP on the port by the dynamic NAT technology.
In this embodiment, the national operator network 4 adopts a china telecommunication network.
