ONT Service-Flow Routing for OTT SLA Assurance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing broadband access structures fail to provide service-level agreement (SLA) assurance for newly emerging services like OTT services due to mixed transmission with triple-play services, lacking dedicated network quality guarantees.
Innovation Solution
Implementing an optical network terminal (ONT) that segregates data packets based on preconfigured service sets, using locally or remotely stored information bases to route packets through distinct paths, ensuring SLA compliance for specific services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If all Internet services are transmitted in a same Internet service flow in a mixed manner, then the transmission path and bandwidth are shared, but the OTT service has no service-level agreement (SLA) assurance
Solution Approach 1:
The patent segments the Internet service flow into multiple service flows based on service types. The ONT divides OTT service data packets from triple-play service data packets into separate service flows, which are then transmitted through different access network paths. This segmentation enables dedicated bandwidth allocation for OTT services, ensuring SLA assurance while maintaining efficient bandwidth utilization across the network.
2Reliability
If data packets are segregated based on preconfigured service sets with distinct transmission paths, then SLA assurance is provided for specific services, but the device complexity increases
Solution Approach 1:
The patent implements preliminary action by preconfiguring service sets and establishing correspondence between service types and transmission paths in advance. The ONT is pre-provisioned with information about which services belong to which service sets and their corresponding access network paths. When data packets arrive, the ONT performs simple matching against the preconfigured information base rather than performing complex real-time analysis, thereby ensuring SLA assurance while minimizing device complexity.
3Speed
If the ONT adds first information about data packets to the information base for services in preconfigured service sets, then subsequent packets can be transmitted through optimized paths, but the information storage and management complexity increases
Solution Approach 1:
The patent applies local quality by making the information base locally stored and manageable at the ONT. The ONT maintains a local information base that stores correspondence between service information and access network paths, allowing rapid local lookup without requiring complex centralized management. This local storage approach enables fast transmission speed for subsequent packets while keeping information base management simple and decentralized.
Data Source
AI summary
A data transmission method includes an optical network terminal (ONT) that receives a first data packet. The ONT matches first information about the first data packet with a locally or remotely stored first information base, where a service corresponding to the first information in the first information base is in a preconfigured service set. When the first information base does not include the first information about the first data packet, the ONT sends, through a first path, the first data packet to a first server corresponding to a first service, and when the ONT determines that the first service is in the preconfigured service set, the ONT adds the first information about the first data packet to the first information base.
