Abstract

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.

Claims23

Dependent claims

A method for coordinating network connections and traffic in a proxy service infrastructure comprising:

selecting, by a DNS server present within the proxy service infrastructure, an IP address of a proxy server, wherein the proxy server is selected based on at least one of the following:
(i) geographical proximity to a client module, (ii) conforming to a client's prerequisites, or (iii) deemed to be appropriate for the client's regular activities;
receiving, by the proxy server, a client request and request parameters from the client module, wherein the client request is addressed to a target;
evaluating, by the proxy server, the request parameters received from the client module to determine whether the proxy server is connected to a suitable edge proxy satisfying the request parameters;
when the proxy server is determined to be connected to the suitable edge proxy, forwarding, by the proxy server, the client request to the suitable edge proxy;
when the proxy server is determined not to be connected to the suitable edge proxy:
(i) identifying, by the proxy server, a subsequent proxy server connected to the suitable edge proxy;
(ii) forwarding, by the proxy server, the client request and request parameters to the subsequent proxy server for forwarding to the suitable edge proxy;
determining, by the proxy server, that client request are frequently serviced through the suitable edge proxy via the subsequent proxy server;
and
when the client requests are determined to be frequently serviced by the suitable edge proxy via the subsequent proxy server, sending, by the proxy server, a transfer message to the subsequent proxy, the transfer message instructing the suitable edge proxy to connect to the suitable edge proxy.
