US Patent 12003600 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, the proxy infrastructure enables network connectivity between exit-nodes and proxy-nodes without the need of any proxy-gateways or middleware entities to delegate the connections. Proxy-nodes in the proxy infrastructure accept connections with exit-nodes based on geographical proximity, proxy-node metrics, such as server loads and clients' frequent preferences. Further, a single instance of proxy-node can communicate and instruct another instance of proxy-node, to service the client request via a suitable exit-node. Further still, a single instance of proxy-node can communicate and instruct another instance of proxy-node to redirect a suitable exit-node towards the first proxy-node in order to service the client request. In another instance, 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.
