Edge Resource Manager Bandwidth Reclamation for Service Expansion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Network operators face challenges in managing and conserving bandwidth, particularly in subscriber television systems, where edge devices are often dedicated to specific digital services, leading to inefficiencies due to varying service popularity, resulting in wasted resources during low demand and service delivery failures during peak times.
Innovation Solution
A method is introduced where a bandwidth query message is communicated to session managers to identify and reclaim bandwidth from edge devices, allowing for the reallocation of resources among different digital services, with policies determining the least disruptive session relocations to support additional sessions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If edge devices are dedicated to specific digital services, then service delivery reliability is improved, but bandwidth utilization efficiency deteriorates
Solution Approach 1:
The patent implements dynamic service migration allowing edge devices to switch between different digital services based on real-time bandwidth availability and demand. The session manager dynamically reallocates services among edge devices, transforming the static dedicated assignment into a dynamic shared resource model that optimizes both reliability and efficiency.
Solution Approach 2:
The system changes the assignment parameter from fixed service-to-edge-device mapping to flexible dynamic mapping. By monitoring bandwidth parameters and service demand, the system adjusts the allocation parameters in real-time, allowing the same edge device to serve different services at different times based on available capacity.
2Loss of energy
If edge device resources are shared among different digital services, then bandwidth utilization efficiency is improved, but service delivery reliability deteriorates
Solution Approach 1:
The session manager continuously monitors bandwidth availability and service demand, using this feedback to make real-time decisions about service allocation. When an edge device becomes unavailable or bandwidth is insufficient, the system receives feedback and automatically migrates services to alternative edge devices, maintaining reliability while sharing resources efficiently.
Solution Approach 2:
The dynamic service migration mechanism allows the system to adapt to changing conditions by reallocation. The edge resource manager dynamically adjusts which services run on which edge devices based on current bandwidth availability, ensuring both efficient resource sharing and reliable service delivery through continuous adaptation.
3Adaptability or versatility
If network capacity is expanded without significant modifications, then service expansion capability is improved, but network infrastructure complexity increases
Solution Approach 1:
The patent implements a universal edge resource management system that handles multiple digital services through a single shared infrastructure. The session manager and edge resource manager work together to allocate any service to any available edge device, allowing the network to expand service capacity without adding physical infrastructure, as the existing multi-functional edge devices are dynamically reassigned.

AI summary
A method is provided for reclaiming bandwidth from an edge device. The method includes communicating a bandwidth query message to at least one session manager. The bandwidth query message specifies an amount of bandwidth that needs to be reclaimed from a single one of a plurality of edge devices in order to establish at least one additional session that delivers a digital service to a subscriber in a service group serviced by the plurality of edge devices over an access network. In response to communication of the bandwidth query message, a bandwidth query response message is received from the session manager identifying an edge device from which at least the specified amount of bandwidth can be reclaimed. A response is communicated to the session manager requesting the session manager to reclaim the specified amount of bandwidth from the edge device that has been identified.
