Protocol Router for Multi-Service Port Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Managing multiple ports on a server machine increases complexity and exposes it to security threats, as each port provides additional access points for hackers.
Innovation Solution
A method that processes requests in a first communication protocol, determines if an identifier for a specific application is present, and provides a socket for communication using a second protocol, allowing the application to communicate directly with the client over the network, even if the initial request is in HTTP, enabling the use of different application layer protocols without burdening the HTTP server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple ports are opened on a server machine to provide access to non-HTTP applications, then service accessibility is improved, but security risk increases due to additional access points for hackers
Solution Approach 1:
The patent combines multiple application protocols (HTTP, HTTPS, FTP, SMTP, etc.) to share a single port (port 80). The protocol determination unit identifies the application protocol from incoming requests on this shared port and routes them to appropriate application processors, allowing multiple services to be accessible through one port rather than requiring separate ports for each protocol
Solution Approach 2:
A single port (port 80) is designed to handle multiple application protocols simultaneously. The system provides universal access point that can process HTTP requests, HTTPS requests, FTP requests, SMTP requests, and other application layer protocols through protocol identification and routing mechanisms, making the port multi-functional
2Adaptability or versatility
If multiple ports are opened on a server machine to host different applications, then application diversity is improved, but system complexity increases due to managing multiple ports
Solution Approach 1:
The patent merges the functionality of multiple protocol-specific ports into a single port (port 80). The protocol determination unit and application processor work together to handle different protocols through one unified entry point, eliminating the need to manage multiple separate ports and their associated firewall rules
Solution Approach 2:
The protocol determination unit acts as an intermediary between the shared port and multiple application processors. It receives requests on port 80, identifies the application protocol, and routes to the appropriate application processor, simplifying port management while supporting diverse applications
Data Source
AI summary
Provided are a method, system, and program for processing requests transmitted using a first communication directed to an application that uses a second communication protocol. A request is received from a client over a network in a first communication protocol. A determination is made as to whether the request includes an identifier of an application indicated in a data structure. A socket is processed that enables communication between the application identified by the identifier in response to determining that the identifier included in the request is indicated in the data structure. The socket is provided to the application associated with the requested resource to enable the application to communicate with the client over the network using a second communication protocol.
