Communication Device Packet Loss Determination via Sequence Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for determining packet loss in communication systems require providing two types of sequence information, leading to increased preprocessing load.
Innovation Solution
A communication device acquires sequence information of communication packets and stores the correspondence relationship between transmission order and sequence information for each route, then determines packet loss based on this information and delivery confirmation information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If two types of sequence information are provided for each route and communication flow, then packet loss determination accuracy is improved, but preprocessing load increases
Solution Approach 1:
The patent extracts and eliminates the unnecessary sequence information for each communication flow, retaining only the sequence information needed for packet loss determination. By removing redundant information (sequence information per flow), the preprocessing load is reduced while maintaining the ability to accurately determine packet loss using only route-specific sequence information combined with delivery confirmation information.
Solution Approach 2:
The patent uses delivery confirmation information as a substitute for the complex two-type sequence information system. Instead of maintaining and processing two separate sequence information structures, the system copies or utilizes the delivery confirmation status to infer packet loss, thereby simplifying the preprocessing requirements while achieving the same determination accuracy.
2Reliability
If sequence information for each route and each communication flow is maintained, then packet loss detection capability is improved, but system complexity increases
Solution Approach 1:
The patent extracts and removes the sequence information component for each communication flow, keeping only the route-level sequence information. This extraction reduces system complexity by eliminating redundant data structures while preserving packet loss detection capability through the combination of route sequence information and delivery confirmation information.
Solution Approach 2:
The patent makes the route-level sequence information universal across all communication flows, rather than maintaining separate sequence information for each flow. This universal approach reduces complexity by having a single sequence information structure serve multiple flows, while the delivery confirmation information provides the flow-specific validation needed for accurate packet loss detection.
Data Source
AI summary
A packet loss is specified in a communication device for transmitting a communication packet to a destination device via a route and receiving a delivery confirmation packet of the communication packet from the destination device. Sequence information of the communication packet for a communication flow is acquired. A correspondence relationship between a transmission order of the communication packet and the sequence information of the communication packet for each route is stored as transmission order correspondence information. Delivery confirmation information indicating a delivery state of the communication packet is acquired. It is determined whether the packet loss has occurred based on the transmission order correspondence information and the delivery confirmation information.
