Transit Node Scheduling for Shared Bandwidth Exclusive Channels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing communication systems, such as optical transport networks (OTN), face low bandwidth utilization due to the limited number of bandwidth exclusive channels that support only end-to-end service data transmission, leading to inefficient use of available bandwidth.
Innovation Solution
Implementing a communication method that allows for statistical multiplexing of data frames within a bandwidth exclusive channel by using a preset bandwidth exclusive channel number, enabling scheduling and congestion control based on scheduling information and congestion levels, and utilizing exclusive bandwidths to improve utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If bandwidth exclusive channels are established for dedicated services, then service reliability is improved, but bandwidth utilization deteriorates
Solution Approach 1:
The patent segments the bandwidth exclusive channel into multiple virtual channels, allowing multiple data flows to share the same physical channel. Each virtual channel maintains independent QoS guarantees while improving overall bandwidth utilization through statistical multiplexing.
Solution Approach 2:
The patent makes the bandwidth exclusive channel multi-functional by enabling it to carry multiple types of traffic simultaneously through virtual channel technology. The channel can serve both dedicated services requiring guaranteed bandwidth and best-effort traffic, improving resource utilization while maintaining service reliability.
2Adaptability or versatility
If the number of bandwidth exclusive channels is increased, then service coverage is improved, but system complexity deteriorates
Solution Approach 1:
The patent merges multiple bandwidth exclusive channels into a shared pool of resources that can be dynamically allocated through virtual channel technology. This reduces the total number of physical channels needed while maintaining the ability to serve multiple services, thereby reducing system complexity while improving service coverage.
Solution Approach 2:
The patent introduces dynamic resource allocation where bandwidth exclusive channels can be flexibly assigned and reassigned based on current service demands. This dynamic approach allows the system to cover more services without proportionally increasing the number of dedicated channels, reducing overall system complexity.
3Loss of energy
If statistical multiplexing is implemented in bandwidth exclusive channels, then bandwidth utilization is improved, but scheduling complexity deteriorates
Solution Approach 1:
The patent applies different scheduling strategies to different virtual channels based on their specific QoS requirements. High-priority traffic receives preferential treatment while best-effort traffic uses simpler scheduling, reducing overall scheduling complexity while maintaining high bandwidth utilization through targeted statistical multiplexing.
Solution Approach 2:
The patent implements feedback mechanisms that monitor channel utilization and dynamically adjust scheduling decisions. This feedback-driven approach enables efficient statistical multiplexing by automatically adapting to traffic patterns, improving bandwidth utilization without requiring complex manual scheduling configurations.
