Transit Agent Cross-LAN Remote Debugging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote debugging technologies are limited to implementing remote debugging within the same local area network (LAN) and cannot establish a direct connection between a debugger and a debuggee located in different LANs due to gateway restrictions.
Innovation Solution
A remote debugging system comprising a remote debugging client, a debugger agent, a transit agent, and a debuggee agent, where the transit agent forwards debugging information between the debugger and debuggee agents using a stored mapping table, enabling cross-LAN remote debugging by encapsulating and decapsulating packets to transmit information across different LANs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a direct connection is established between debugger and debuggee in different LANs, then remote debugging functionality is improved, but network gateway restrictions prevent direct connection
Solution Approach 1:
The patent introduces agents (debugger agent, transit agent, debuggee agent) as intermediaries to establish indirect communication between the debugger and debuggee across different LANs. The transit agent acts as a mediator that receives packets from the debugger agent, performs decapsulation, queries the mapping table to find the corresponding debuggee agent, and forwards the packet to the target LAN, thereby bypassing gateway restrictions.
Solution Approach 2:
The patent segments the remote debugging system into multiple independent components: the debugger client, debugger agent in the first LAN, transit agent in an intermediate network, and debuggee agent in the second LAN. This segmentation allows each component to operate independently within its own network boundary while maintaining overall system functionality through standardized packet protocols and mapping tables.
2Adaptability or versatility
If agents and mapping tables are introduced to enable cross-LAN debugging, then network adaptability is improved, but system complexity increases
Solution Approach 1:
The transit agent is designed as a universal component that can handle mapping table queries and packet forwarding for multiple different LAN configurations. The mapping table structure provides a universal mechanism for establishing correspondences between debugger agents and debuggee agents across any number of networks, making the system adaptable without requiring custom solutions for each scenario.
Solution Approach 2:
The mapping table is pre-established to store the correspondence relationships between debugger agents and debuggee agents before actual debugging sessions begin. This preliminary action allows the transit agent to quickly resolve packet forwarding targets without complex real-time negotiations, reducing runtime complexity while maintaining adaptability.
