Solution Overview
Problem
In data networks, the increasing number of network application proxies leads to redundant efforts and inconsistent handling, resulting in undesirable behavior, highlighting the need for a common network proxy layer to provide a consistent and efficient mechanism for processing data.
Innovation Solution
Implementing a network proxy layer that processes data efficiently and consistently across multiple application proxies, involving a method where connection establishment events and data packets are managed through a network interface module, with a state machine to handle client and server connections, and additional processing for security and service policies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple network application proxies are deployed to handle different applications, then the network device can provide diverse application services, but redundant efforts and inconsistent handling occur leading to undesirable behavior
Solution Approach 1:
The patent merges multiple application proxies into a unified proxy structure where a single network application proxy handles multiple applications. This is achieved by introducing an application identifier parameter that allows the proxy to distinguish between different applications while maintaining a consistent handling mechanism, thereby eliminating redundant efforts and ensuring uniform processing across all applications.
Solution Approach 2:
The network application proxy is designed with multi-functionality to handle diverse applications through a single unified interface. By incorporating application-specific parameters (such as application identifiers) into the universal proxy framework, the system achieves versatility in supporting multiple applications while maintaining consistent and reliable handling through the same proxy mechanism.
2Adaptability or versatility
If multiple network application proxies are deployed to handle different applications, then the network device can provide diverse application services, but redundant processing effort increases
Solution Approach 1:
The patent combines multiple application proxies into one unified proxy that processes data for multiple applications simultaneously. This merging eliminates redundant processing efforts by avoiding duplicate data handling and security checks that would occur if separate proxies were used for each application, thereby improving overall processing efficiency while maintaining the ability to serve diverse applications.
Solution Approach 2:
The unified network application proxy is designed to perform multiple functions across different applications through a single processing pipeline. By using application identifiers to route and process data appropriately within the same proxy structure, the system achieves versatile application support without the overhead of multiple separate proxy instances, thus enhancing productivity.
3Reliability
If a common network proxy layer is implemented to provide consistent handling, then processing efficiency and consistency improve, but the device complexity increases
Solution Approach 1:
The patent segments the proxy functionality by introducing distinct parameters for different applications (such as application identifiers, security policies, and service parameters) while maintaining a unified proxy structure. This segmentation allows the common network proxy layer to handle multiple applications consistently without requiring separate proxy instances, thereby improving reliability while managing complexity through structured parameterization.
Solution Approach 2:
The unified network application proxy acts as an intermediary between the network and multiple applications, mediating all communication through a single consistent interface. This intermediary approach ensures handling consistency across all applications while managing complexity by centralizing the proxy logic and using parameters to differentiate application-specific requirements, rather than duplicating proxy structures.
Data Source
AI summary
A system and method for providing a network proxy layer are disclosed. The network proxy layer may receive a connection establishment event for a client connection of an application session and send the client connection event to an application proxy for the application session, the application proxy being associated with an application of a server. Upon establishment of the client connection, the network proxy layer may receive one or more data packets from the client connection. The network proxy layer may further receive a connection establishment event for a server connection of the application session of the server, and receive one or more data packets from the server connection.
