Multi-Domain Orchestrator for Guaranteed Wi-Fi Bandwidth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cable network systems cannot guarantee end-to-end bandwidth on-demand for wireless connections due to domain restrictions, where DOCSIS domain is limited for dynamic bandwidth configuration and QoS negotiation is restricted to the Wi-Fi domain.
Innovation Solution
A multi-domain orchestrator unifies the DOCSIS and Wi-Fi domains through PacketCable Multimedia (PCMM) and Opensync protocols, facilitating communication and configuration to provision guaranteed bandwidth over both wired and wireless links, performing speed tests and QoS negotiations to dynamically adjust bandwidth offers based on available resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If domain-specific protocols are used for bandwidth configuration and QoS negotiation, then each domain can be optimized for its specific requirements, but end-to-end bandwidth guarantee cannot be achieved across multiple domains
Solution Approach 1:
The patent introduces a multi-domain orchestrator as an intermediary component that mediates between DOCSIS and Wi-Fi domains. This orchestrator receives bandwidth requests from client devices, evaluates available resources in both domains, performs QoS negotiations, and coordinates bandwidth provisioning across the cable and wireless links. By centralizing this coordination function, the system achieves end-to-end bandwidth guarantees while managing the complexity of multi-domain interaction through a single unified controller.
2Adaptability or versatility
If dynamic bandwidth provisioning is implemented in DOCSIS domain, then on-demand bandwidth allocation is improved, but QoS negotiation capability is limited to Wi-Fi domain only
Solution Approach 1:
The multi-domain orchestrator implements a universal control function that handles both DOCSIS and Wi-Fi domain operations through a single system. It receives bandwidth requests, evaluates resources in both domains, performs QoS negotiations using appropriate protocols for each domain (PCMM for DOCSIS, OpenFlow for Wi-Fi), and coordinates provisioning across both links. This universal approach enables on-demand bandwidth provisioning to work seamlessly across both domains without requiring separate independent systems.
3Reliability
If bandwidth is guaranteed over multiple domains, then user experience is improved, but network configuration complexity increases
Solution Approach 1:
The multi-domain orchestrator implements self-service functionality by automatically receiving bandwidth requests from client devices, evaluating available resources in both DOCSIS and Wi-Fi domains, performing QoS negotiations, and coordinating bandwidth provisioning without requiring manual network configuration. The system autonomously manages the complexity of multi-domain coordination, making bandwidth guarantee implementation easier while maintaining reliable service levels.

AI summary
Systems and methods for guaranteeing end-to-end QoS for wireless connections over a cable network are disclosed. Provisioning of on-demand guaranteed bandwidth connection over a cable network uses mechanisms from DOCSIS domain and Wi-Fi domain. A multi-domain orchestrator is implemented to control both domains. A bandwidth request is received from a client device connecting to a network service provider access point. The bandwidth request is updated for both domains with results of speed test of the wireless link if the speed test results are lower than the bandwidth request. The orchestrator and client device negotiate the bandwidth request using a three-way handshake over PacketCable Multimedia (PCMM) protocol. If the available bandwidth on either the DOCSIS or wireless link is less than the bandwidth request, the orchestrator generates a new bandwidth offer. If the client device accepts the offer, the orchestrator configures the DOCSIS and wireless links using their respective domain protocols to provision the connection with guaranteed end-to-end bandwidth.
