Transmission Window Multiplexing for FlexE Bandwidth Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing technologies in flexible Ethernet (FlexE) and optical transport networks (OTN) result in bandwidth resource wastage when small-granularity services are transmitted using divided slots, as each slot can only carry service data for one service.
Innovation Solution
The method involves dividing the unit time period or data frame into multiple transmission windows and allocating these windows to multiple services, allowing for multiplexing of services within a single time period or data frame, thereby optimizing bandwidth usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If bandwidth resources are managed in a slot division manner with one slot allocated to one service, then service data can be transmitted based on divided slots, but a large waste of bandwidth resources occurs for small-granularity services
Solution Approach 1:
The patent segments the time period or data frame into multiple transmission windows, allowing a single slot to be divided into multiple time segments that can be allocated to different services. This segmentation enables fine-grained resource allocation while maintaining the overall slot structure, thereby reducing bandwidth waste for small-granularity services.
Solution Approach 2:
The patent introduces dynamic allocation of transmission windows within slots, where the number and allocation of windows can be adjusted based on service requirements. This dynamic approach allows the system to adapt to different service granularities, optimizing bandwidth utilization while maintaining simple slot-based management.
2Ease of operation
If one slot is allocated to carry service data of only one service, then service data can be transmitted based on divided slots, but a waste of bandwidth resources occurs because the one time period or the one data frame can carry only one service
Solution Approach 1:
The patent segments each slot into multiple transmission windows, allowing multiple services to share a single slot by being assigned different time segments. This maintains the simplicity of slot-based management while enabling multiple services to be carried within one slot, thereby improving bandwidth utilization efficiency.
Solution Approach 2:
The patent introduces a time dimension by dividing slots into transmission windows, transforming the traditional one-dimension (one slot per service) allocation into a two-dimension (slot × time window) allocation scheme. This allows multiple services to be multiplexed within the same slot by assigning them different time windows, improving productivity without complicating operation.

AI summary
This application discloses a service processing method and apparatus, and belongs to the field of communication technologies. In this application, a unit time period or a unit data frame may be divided into m transmission windows, and then corresponding transmission windows are allocated to each service based on a quantity of transmission windows required by each of n to-be-mapped services to transmit the service. Further, service data of the n services is multiplexed, based on the transmission windows corresponding to each service, into data transmitted in one channel. In this way, a plurality of services may be multiplexed within one time period or in one data frame for service transmission, thereby avoiding a waste of bandwidth resources that occurs because the one time period or the one data frame can carry only one service.
