Network Reconfiguration via Customer Premises Application Hosting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In software-defined networks (SDNs), the ever-changing network topology due to the creation and destruction of virtual network functions (VNFs) leads to non-optimal network service deployment at the edge, particularly in traditional networks transitioning to SDN infrastructure, where service elements are constantly being created and destroyed, resulting in suboptimal service delivery.
Innovation Solution
A processing system within the telecommunication network, such as an SDN controller or SFC orchestrator, uses a dynamic learning map to identify suitable resources for network service deployment, including customer premises-based devices, and reconfigures the network to instantiate service provider applications on these devices, optimizing for minimal latency and resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If virtual network functions are constantly created and destroyed in SDN infrastructure, then network flexibility and adaptability improve, but network service deployment optimality deteriorates due to ever-changing topology
Solution Approach 1:
The patent implements dynamic service deployment by continuously monitoring network topology changes and automatically reconfiguring service paths. The system adapts to VNF creation/destruction events in real-time, adjusting service chains to maintain optimality despite changing network conditions. This dynamic approach resolves the contradiction by making the system responsive to topology changes rather than static.
Solution Approach 2:
The patent employs feedback mechanisms where the system continuously monitors network topology state and service performance, then uses this information to make intelligent deployment decisions. The feedback loop enables the system to detect topology changes caused by VNF lifecycle events and automatically adjust service deployments to maintain optimality, thereby preserving service deployment quality despite network flexibility.
2Speed
If network edge is pushed closer to customer premises with new devices and SDN architectures, then service delivery speed improves, but network complexity increases
Solution Approach 1:
The patent implements network functions as virtualized services that can be deployed on universal hardware platforms at the network edge. Instead of requiring specialized devices for each function, the system uses multi-functional virtualized infrastructure that can host multiple network services on standard customer premises equipment, thereby reducing device complexity while maintaining fast service delivery.
Solution Approach 2:
The patent replaces physical network infrastructure complexity with software-defined network functions. Instead of deploying complex specialized hardware at customer premises, the system uses virtualized network functions that run on software platforms, substituting mechanical/physical complexity with software-based solutions that are easier to manage and deploy.
3Adaptability or versatility
If service elements are constantly created and destroyed, then network adaptability improves, but service delivery optimality deteriorates
Solution Approach 1:
The patent implements preliminary service deployment planning by pre-configuring service chain templates and policies before topology changes occur. When VNFs are created or destroyed, the system has pre-prepared alternative paths and service configurations ready to deploy, minimizing the impact on service delivery optimality while maintaining network adaptability to changes.
Data Source
AI summary
Methods, computer-readable media, and devices for instantiating a service provider application of a network service on a customer premises-based device are disclosed. For example, a processing system of a telecommunication network having at least one processor may receive a request for a network service, identify a set of resources for the network service, the set of resources for the network service including at least a first service provider application, and determine that a current configuration of the telecommunication network does not provide the set of resources. The processing system may further reconfigure the telecommunication network to provide the set of resources, the reconfiguring including instantiating the at least the first service provider application of the network service on a customer premises-based device, and deploying the network service to the telecommunication network that is reconfigured.
