Nested Request-Response Protocol for Device Capability Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication protocols, such as REST and HTTP, are inadequate for transactional tasks involved in coordinating capabilities between networked computing devices, leading to operational delays and inefficiencies.
Innovation Solution
The proposed solution involves adapting existing request-response protocols by nesting request-response communications to introduce stateful transactions, ensuring compatible operations between networked devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If individual instances of request-response protocol are used for communication, then web-based and network-based applications can operate, but coordination of capabilities between devices becomes inefficient and delayed
Solution Approach 1:
The patent implements nested request-response instances where a parent request-response pair encapsulates one or more child request-response pairs. This nesting structure allows multiple capability coordination tasks to be executed within a single communication transaction, eliminating the need for sequential individual exchanges and significantly improving coordination efficiency while reducing operational delays.
2Adaptability or versatility
If existing request-response protocols are used, then widespread compatibility is maintained, but stateful transactions for capability coordination cannot be properly supported
Solution Approach 1:
The patent introduces dynamic state management within nested request-response instances, where parent and child instances can transition between different states (pending, in-progress, completed, failed). This dynamic state tracking enables reliable capability coordination while maintaining compatibility with existing request-response protocols, as the state information is carried within the protocol messages themselves rather than requiring external state storage.
3Ease of operation
If asynchronicity is used in request-response communications, then device independence is achieved, but determination of aligned capability states becomes difficult
Solution Approach 1:
The patent implements feedback mechanisms where each nested request-response instance carries state information and capability data that allows devices to determine alignment. The parent instance coordinates capability states by receiving feedback from child instances, and the nested structure preserves asynchronicity while enabling reliable state determination through structured information exchange and acknowledgment messages.
Data Source
AI summary
A controller computing device may include one or more processors and memory containing controller data representing controller computing device capabilities. The one or more processors may be configured to transmit on a first instance of a request-response protocol, a controller request, including the controller data, to an agent computing device. The controller computing device may then receive, from the agent computing device, an agent request on a second instance of the request-response protocol. The agent request may include agent data representing agent computing device capabilities. The controller computing device may store the agent data in the memory, and transmit on the second instance of the request-response protocol, to the agent computing device, a controller response acknowledging receipt of the agent request. The controller computing device may then receive on the first instance of the request-response protocol from the agent computing device, an agent response acknowledging receipt of the controller request.
