Optical Gateway Frame Length Compression for Low-Latency Downlink
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The optical gateway in P2MP networks cannot compress the downlink frame length, leading to excessive latency and packet loss in scenarios requiring lower latency, such as latency-sensitive services or centralized scheduling of wireless and cache resources.
Innovation Solution
The optical gateway compresses the downlink frame length based on target parameters, including service type and centralized scheduling parameters, and sends the compressed frame length to the optical router, adjusting the frame length to specific ranges or using compression algorithms to meet latency requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the downlink frame length is fixed at 125 us according to GPON standards, then the network compatibility and standard compliance are improved, but the latency increases excessively leading to packet loss in latency-sensitive scenarios
Solution Approach 1:
The patent applies dynamics by making the downlink frame length adjustable rather than fixed. The optical gateway dynamically determines the downlink frame length based on service type and scheduling requirements, allowing the system to adapt between standard-compliant fixed length and optimized variable length modes to resolve the contradiction between compatibility and latency
Solution Approach 2:
The patent changes the parameter of downlink frame length from a fixed value (125 us) to a variable parameter that can be adjusted according to service requirements. By modifying this critical parameter dynamically, the system achieves lower latency for latency-sensitive services while maintaining compatibility with GPON standards through configurable operation
2Speed
If the downlink frame length is compressed to reduce latency, then the communication speed and latency performance are improved, but the device complexity increases due to additional processing requirements
Solution Approach 1:
The optical gateway performs self-service by autonomously determining the appropriate downlink frame length based on service type and scheduling parameters without requiring complex external control. The gateway independently decides whether to use compressed or standard frame lengths, reducing the need for additional complex coordination mechanisms
Solution Approach 2:
The patent simplifies complexity management by focusing on a single key parameter change - the downlink frame length - rather than implementing complex multi-parameter optimization systems. This targeted parameter adjustment achieves performance improvement without proportionally increasing overall system complexity
