Traffic Flow Grouping for Mixed Rate PHY Channels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network communication technologies lack standards and methods for delivering traffic on physical channels with rates that are integer multiples of 100 G or mixed physical layers with different rates, such as 200 G or 400 G, leading to inefficiencies and increased costs.
Innovation Solution
A traffic delivery method that determines the number of traffic flows based on bandwidth, groups them according to a preset policy, and matches them with corresponding PHY transport channels, allowing for efficient transmission on channels with varying rates by interpolating or separating flows as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a 400 G optical module is used to deliver traffic, then the delivery bandwidth is improved, but the cost increases significantly
Solution Approach 1:
The patent segments the traffic delivery function by dividing 400G traffic into multiple 100G traffic flows, which are then transmitted through multiple 100G optical modules. This segmentation allows the system to achieve 400G delivery capability without requiring expensive 400G optical modules, thereby reducing cost while maintaining productivity.
2Quantity of substance
If multiple 100 G optical modules are bundled to form a 400 G logical channel, then the cost is reduced, but the device complexity increases
Solution Approach 1:
The patent introduces a FlexE shim layer as an intermediary between the MAC layer and PCS layer to manage the bundling of multiple 100G optical modules. This intermediary layer provides standardized protocols for traffic flow management, grouping, and mapping, which simplifies the overall system complexity despite using multiple modules.
Solution Approach 2:
The patent creates a universal traffic delivery framework that can handle multiple 100G optical modules through standardized FlexE protocols. This multi-functional approach allows the same infrastructure to support various configurations (1x100G, 2x100G, 4x100G) without requiring separate specialized systems for each configuration.
3Adaptability or versatility
If the FlexE protocol is used to bundle 100 G physical channels, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The patent implements dynamic traffic flow management within the FlexE framework, where traffic flows can be dynamically grouped, mapped, and remapped based on network conditions and requirements. This dynamic capability provides high adaptability while the standardized protocol structure prevents excessive complexity by providing clear management rules.
4Productivity
If traffic is delivered on physical channels with rates being integer multiples of 100 G, then the productivity is improved, but the ease of operation deteriorates due to lack of standards
Solution Approach 1:
The patent standardizes the physical channel rates to be integer multiples of 100G (100G, 200G, 300G, 400G) and develops corresponding FlexE protocols for each rate. This parameter standardization improves productivity by enabling higher bandwidth delivery while making operation easier through standardized protocols and procedures for each rate level.
