uCPE to vCPE Traffic Migration via PoP Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Centralized NFV platforms face challenges in scaling and high availability (HA) when integrated with universal customer premises equipment (uCPE) platforms due to limited resources, leading to potential overloading of virtual customer premises equipment (vCPE) resources during traffic migration.
Innovation Solution
Implementing a selection process to migrate traffic flows from uCPE platforms to vCPE platforms based on traffic flow characteristics, such as service level agreement (SLA), priority, and destination path, while selecting suitable points of presence (PoPs) that minimize resource overload and optimize bandwidth and cost, thereby ensuring scaling and HA without overloading vCPE resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traffic flows are migrated from uCPE platform to vCPE platform to resolve issues, then reliability is improved, but device complexity increases due to need for selection processes and resource management
Solution Approach 1:
The system performs preliminary actions by pre-establishing selection criteria for traffic flows and PoPs before migration occurs. Traffic flows are evaluated against SLA, priority, and destination path characteristics in advance, and suitable PoPs are pre-identified along traffic paths. This preliminary preparation enables reliable migration decisions to be made quickly when issues are detected, improving high availability while managing complexity through structured pre-planning.
2Productivity
If more traffic is migrated to vCPE platform to achieve scaling, then productivity is improved, but resource overload occurs on vCPE platform
Solution Approach 1:
The system changes parameters by evaluating multiple characteristics of traffic flows (SLA, priority, destination path) and PoPs (utilization, load, cost) to make migration decisions. By monitoring and responding to changes in these parameters, the system can scale traffic migration to improve productivity while preventing resource overload through dynamic parameter-based control.
Solution Approach 2:
The system implements feedback mechanisms by monitoring PoP utilization and load conditions. When PoPs approach capacity thresholds, the selection process adjusts to avoid migrating additional traffic to overloaded resources. This feedback loop enables the system to achieve scaling while maintaining resource balance and preventing overload on the vCPE platform.
3Speed
If traffic migration is performed without selection process to improve response time, then speed is improved, but resource overload and failures occur
Solution Approach 1:
The system performs preliminary evaluations of traffic flows against selection criteria (SLA, priority, destination path) and identifies suitable PoPs along traffic paths before migration is triggered. This pre-preparation enables the system to make rapid migration decisions when issues occur, improving response speed while maintaining reliability through structured selection processes that prevent arbitrary or harmful migrations.

AI summary
A device may include one or more processors to detect an issue in a universal customer premises equipment (uCPE) platform; select a traffic flow to migrate from the uCPE platform to a virtual customer premises equipment (vCPE) platform, the traffic flow may be selected based on a characteristic of the traffic flow; determine a traffic path of the traffic flow through the vCPE platform; select a point of presence (PoP) of the vCPE platform to host a virtual network function (VNF) associated with the traffic flow based on the PoP being situated along the traffic path; and perform an action associated with the PoP or the traffic flow to resolve the issue.
