Edge Termination Point Transport Protocol for Resource Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current networking technologies face challenges in efficiently managing resource allocation and flow control in information-centric networking (ICN) environments, particularly in maintaining TCP friendliness and ensuring fair resource sharing across multiple flows, which can lead to bottlenecks and degraded performance.
Innovation Solution
Implementing edge termination points (ETPs) in a Layer 2 transport network that perform ad-hoc TCP flow control by determining a common denominator for resources, such as maximum round-trip time or lowest credit value, and establishing a resource management regime that includes flow parameters like credit, timers, and error rate information to manage ETP-to-ETP communications, allowing for efficient mapping of IP transactions and error control mechanisms.

Engineering Contradiction Analysis
1Productivity
If ad-hoc TCP flow control is implemented by determining common denominator for resources, then resource allocation efficiency is improved, but device complexity increases
Solution Approach 1:
The patent introduces an intermediary mechanism (common denominator calculation) that mediates between multiple ETP-to-ETP transactions and TCP flow control requirements. This intermediary layer translates complex multi-flow resource management into a standardized TCP-compatible control mechanism, improving resource allocation efficiency while managing device complexity through abstraction.
Solution Approach 2:
The patent changes key parameters by determining common denominators for resource allocation (maximum RTT timer, lowest credit value) across multiple transactions. This parameter transformation approach converts variable resource requirements into standardized control parameters, enabling efficient resource management without proportionally increasing device complexity.
2Reliability
If resource management regime with multiple flow parameters is established, then network reliability is improved, but device complexity increases
Solution Approach 1:
The patent segments the resource management regime into distinct flow parameters (credit, timers, error rate information) that can be independently managed and controlled. This segmentation allows each parameter to be optimized for specific reliability aspects without requiring the entire system to become proportionally more complex, enabling targeted reliability improvements.
Solution Approach 2:
The resource management regime is designed with universal applicability across multiple ETP-to-ETP transactions, where a single set of flow parameters can manage multiple flows. This multi-functionality approach improves network reliability through comprehensive resource control while avoiding the complexity increase that would result from implementing separate management mechanisms for each transaction.
3Productivity
If ETP-to-ETP communication is controlled based on resource management regime, then bandwidth sharing fairness is improved, but loss of time increases
Solution Approach 1:
The patent implements preliminary action by pre-establishing flow parameters (credit values, timers) in the resource management regime before actual data transmission begins. This preliminary configuration enables fair bandwidth sharing to be automatically enforced during transmission without requiring real-time negotiation or control decisions, thus improving fairness while minimizing time loss.
4Reliability
If error control information is included in ETP transactions, then network reliability is improved, but quantity of substance increases
Solution Approach 1:
The patent extracts error control information as a separate, dedicated component within ETP transactions rather than embedding it throughout the entire data payload. This extraction approach ensures reliable error detection and control while minimizing the quantity increase, as only essential error control data (sequence numbers, error indicators) are included rather than redundant information throughout the transmission.

AI summary
An edge termination point (ETP) transport protocol between two or more ETPs in a network, such as a Layer 2 transport network, may be provided. A device may receive an incoming internet protocol (IP) transaction at an edge termination point (ETP) in a network. The device may terminate the received incoming IP transaction at the ETP. The device may map the terminated incoming IP transaction onto an ETP-to-ETP communication. The device may control the ETP-to-ETP communication. For example, the device may control the ETP-to-ETP communication based on a resource management regime. The device may map the ETP-to-ETP communication onto one or more outgoing IP transactions at the ETP. The device may map the IP transaction onto an ETP-ETP communication. The ETP-ETP communication may include one or more ETP flows and one or more ETP transactions.
