Proxy Service Routing Through Separate Request And Response Supernodes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing proxy service providers face challenges in maintaining a reliable and efficient proxy service infrastructure due to high network traffic, latency, and the need for robust infrastructure, which affects network load handling, load balancing, and client experience.
Innovation Solution
Implementing a proxy service environment where exit-nodes connect to multiple supernodes, allowing network traffic to be forwarded to and response traffic returned from different supernodes, enhancing high availability and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a proxy server uses a single supernode to handle client requests, then the system structure is simple, but the reliability and availability are reduced due to potential single points of failure
Solution Approach 1:
The system segments the proxy service infrastructure into multiple independent supernodes instead of relying on a single supernode. Each supernode can independently handle client requests, and the segmentation allows for distributed processing across multiple nodes, thereby improving reliability while managing complexity through modular architecture
Solution Approach 2:
The system changes the parameter of supernode connectivity from single-point connection to multi-point connection. Exit nodes are configured to maintain connections with multiple supernodes simultaneously, and the system dynamically selects which supernode to use for each request, changing the connectivity parameter to enhance reliability
2Productivity
If proxy servers handle high network traffic through centralized routing, then the routing logic is simple, but the network load handling capability and latency performance deteriorate
Solution Approach 1:
The system segments the traffic handling capacity across multiple supernodes rather than concentrating all traffic through a single routing point. This segmentation distributes the network load handling capacity, preventing any single node from becoming a bottleneck and thereby improving both productivity and reducing latency
Solution Approach 2:
The system implements dynamic supernode selection where exit nodes can switch between multiple connected supernodes based on current load conditions, performance metrics, and availability. This dynamic behavior allows the system to adapt to changing traffic patterns, optimizing network load handling and minimizing latency by routing through the most appropriate supernode at any given time
3Reliability
If the proxy environment uses multiple supernodes for high availability, then the reliability improves, but the device complexity and routing management difficulty increase
Solution Approach 1:
The exit nodes are equipped with self-service capabilities to automatically manage their connections to multiple supernodes. They autonomously perform health checks, monitor supernode availability, and dynamically select appropriate supernodes without requiring complex external management systems, thereby reducing the overall management complexity while maintaining high availability
Solution Approach 2:
The system implements feedback mechanisms where exit nodes continuously monitor the status and performance of connected supernodes. Based on this feedback, they can automatically adjust their routing decisions, switching to alternative supernodes when performance degrades or nodes become unavailable, thereby maintaining reliability while simplifying management through automated feedback-driven decisions

AI summary
Systems and methods to manage and efficiently implement functional proxy services are disclosed. In the proxy services, a single instance of exit-node is connected to at least two or multiple supernodes at any given time. One of the plurality of supernodes is configured to ping and send diagnostic requests to the connected exit-node through a network. The exit-node is directed to send the pong message and diagnostic response data to a different supernode from among the plurality of supernodes connected to the exit-node. Likewise, a client's request is received by an element of the proxy service provider and forwarded to a specific supernode capable of forwarding the client's request to the exit-node. After performing the client's request, the exit-node returns response data to a different supernode from among the plurality of supernodes connected to the exit-node.
