Solution Overview

Problem

Proxy infrastructures face challenges such as connection losses, unavailability of proxy servers, system errors, bandwidth limitations, and longer transaction times, which affect performance and client satisfaction.

Innovation Solution

Implementing proxy supernodes and exit proxies that establish persistent WebSocket communication channels for bi-directional, full-duplex data exchange, allowing them to communicate independently and reduce network latency through continuous 'ping-pong' processes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If traditional HTTP request-response communication is used between proxy servers, then connection establishment is simple, but network latency increases and transaction efficiency decreases due to repeated handshake processes

Engineering Contradiction:

Improvenetwork latencyVSAvoidcommunication channel maintenance complexity

Core Design Contradiction:

Loss of timeVSDevice complexity

Solution Approach 1:

The patent establishes WebSocket persistent channels in advance between proxy servers before actual proxy requests occur. This preliminary action creates a pre-existing communication pathway that eliminates the need for repeated TCP handshakes and HTTP protocol exchanges for each request, thereby reducing network latency while the system manages channel lifecycle events to handle complexity

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent maintains continuous WebSocket persistent channels between proxy servers, enabling uninterrupted bidirectional communication. This continuous connection allows proxy requests and responses to be transmitted immediately without connection establishment delays, improving transaction efficiency while the channel management system handles maintenance complexity

Inventive Principle:

Principle #20Continuity of useful action

2Productivity

If multiple proxy servers are connected through persistent channels, then communication efficiency improves, but connection loss and server unavailability issues increase system complexity

Engineering Contradiction:

Improvecommunication efficiencyVSAvoidconnection stability

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent implements a channel manager that continuously monitors the status of WebSocket persistent channels between proxy servers. When connection losses or server unavailability occur, the manager detects these changes through feedback mechanisms and automatically triggers reconnection or failover procedures, maintaining communication efficiency while managing reliability issues

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent establishes redundant persistent channels between proxy servers in advance, creating backup communication pathways before failures occur. This beforehand cushioning ensures that if a primary channel fails due to connection loss or server unavailability, alternative channels are already in place to maintain communication efficiency without significant disruption

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

3Productivity

If HTTP caching operations are used to reduce direct user-server communication, then network bottlenecks are prevented, but transaction time increases due to additional proxy processing steps

Engineering Contradiction:

Improvenetwork throughputVSAvoidtransaction time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The patent establishes persistent WebSocket channels between proxy servers that remain continuously open, enabling immediate transmission of cached resources without repeated protocol handshakes. This continuous communication pathway allows caching operations to deliver resources faster by eliminating redundant connection establishment time, improving transaction time while maintaining network throughput benefits

Inventive Principle:

Principle #20Continuity of useful action

AI summary

Proxy servers within a service provider infrastructure are enabled to maintain multiple persistent connections among themselves and to exchange data bi-directionally in an unsolicited manner. Specifically, exit proxy servers are enabled to request their respective proxy supernodes to update the already existing network connection to support WebSocket communication channels. Accordingly, the respective proxy supernodes are enabled to update the network connection with the exit proxy servers to support WebSocket communication channels. A single instance of a proxy supernode and an exit proxy server can maintain multiple WebSocket communication channels with each other. By utilizing the said WebSocket communication channels, the proxy supernode and the exit proxy servers can exchange data with each other simultaneously without any data losses. Thus, by exchanging data via the said WebSocket communication channels, the proxy supernodes and the exit proxy servers are aimed at servicing the proxy clients in processing their data requests.
