FlexE Interface Segmentation for Service Flow Priority Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current service flow transmission methods in Flexible Ethernet (FlexE) networks experience interference between high-priority service flows, leading to increased jitter and transmission delays, which cannot meet the communication requirements of users.
Innovation Solution
The method involves acquiring service flows and transmitting them via different Flexible Ethernet (FlexE) outgoing interfaces based on their priorities, thereby avoiding mutual interference between high-priority service flows.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the same FlexE interface is used to transmit different types of high-priority service flows, then device complexity is reduced, but interference between service flows increases leading to increased jitter
Solution Approach 1:
The patent segments the transmission path by creating separate FlexE outgoing interfaces for different types of high-priority service flows. Instead of using a single interface for all high-priority flows, the system divides the transmission path into multiple dedicated interfaces (e.g., first FlexE outgoing interface for control signaling, second for motion control, third for audio, fourth for video), thereby eliminating interference between different service flow types while maintaining manageable device complexity through structured segmentation.
2Device complexity
If cyclic queue forwarding is used to schedule different priorities of service flows, then device complexity is reduced, but transmission delay of high-priority service flows increases
Solution Approach 1:
The patent segments the transmission process by assigning dedicated FlexE outgoing interfaces to different service flow types, eliminating the need for cyclic queue forwarding scheduling. High-priority service flows are transmitted through their dedicated interfaces without waiting for scheduling cycles, thereby reducing transmission delay while maintaining simple direct transmission logic rather than complex scheduling mechanisms.
Solution Approach 2:
The patent introduces dedicated FlexE outgoing interfaces as intermediaries between the service flow classification and transmission. Instead of using a single shared interface with scheduling logic, each high-priority service flow type has its own intermediary interface, allowing direct transmission without scheduling delays and eliminating the need for complex cyclic queue forwarding mechanisms.
3Productivity
If the same FlexE interface transmits all high-priority service flows, then interface utilization is improved, but mutual interference between service flows increases
Solution Approach 1:
The patent segments the transmission path by creating separate FlexE outgoing interfaces for different types of high-priority service flows. Instead of using a single interface for all high-priority flows, the system divides the transmission path into multiple dedicated interfaces (e.g., first FlexE outgoing interface for control signaling, second for motion control, third for audio, fourth for video), thereby eliminating interference between different service flow types while maintaining manageable device complexity through structured segmentation.
Solution Approach 2:
The patent applies local quality by assigning specific characteristics to different transmission paths. Each dedicated FlexE outgoing interface is optimized for its specific service flow type, with control signaling flows receiving priority treatment separate from media flows. This localized optimization ensures that each service flow type receives appropriate transmission characteristics without interfering with other types, improving overall system performance.
