Network coordination between proxy servers
Systems and methods for coordinating network connectivity and communication between proxy servers, exit-nodes and client modules are disclosed. In one aspect, proxy-nodes in a proxy infrastructure accept connections with exit-nodes based on geographical proximity or proxy-node metrics. Further, a proxy-node can communicate and instruct another proxy-node to service the client request via a suitable exit-node. Further still, a proxy-node can communicate and instruct proxy-node to redirect a suitable exit-node towards the first proxy-node in order to service the client request. In another aspect, the proxy-infrastructure enables client modules to connect to proxy-nodes based on geographical proximity, client parameters, and client's behavioral informatics. In yet another aspect, proxy infrastructure enables a proxy node to redirect exit-nodes to a different proxy-node in the event of a) system overload or resource exhaustion, b) graceful shutdown c) erroneous network connection between exit-nodes and the proxy-node.

issuing, by the proxy server, a redirect message to at least one edge proxy having a network connection with the proxy server, wherein the redirect message instructs the at least one edge proxy to connect to the alternate proxy server;
receiving, by the proxy server, a message from the at least one edge proxy confirming successful connection with the alternate proxy server; and
terminating, by the proxy server, the network connection with the at least one edge proxy.

issuing, by the proxy server, a redirect message to the edge proxy, wherein the redirect message instructs the edge proxy to connect to the suitable proxy server;
receiving, by the proxy server, a message from the edge proxy confirming successful connection with the suitable proxy server; and
terminating, by the proxy server, the erroneous connection with the edge proxy.
10. The computer-implemented method of claim 9 , wherein the proxy-node metadata for each proxy server in the plurality of proxy servers comprises IP address, unique identifier, geo-location, total number of connected edge proxies, and IP addresses of the connected edge proxies.
