Shared Redundancy Protocol for Virtualized Infrastructure Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current virtualized infrastructure lacks an efficient method for resource allocation that provides reliability guarantees, leading to over-provisioning of resources and potential disruptions during node failures, as existing solutions do not effectively address the allocation of compute capacity while maintaining redundancy across virtual networks.
Innovation Solution
A resource allocation protocol that allocates physical resources to primary and redundant virtual infrastructures, allowing shared redundancy across multiple primary virtual infrastructures, utilizing a n:k redundancy architecture to minimize resource usage and ensure reliability with joint node and link redundancy, and statically allocating compute capacity, storage, and bandwidth to maximize virtual resource accommodation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical resources are duplicated to provide reliability guarantees in virtualized infrastructure, then reliability is improved, but resource utilization deteriorates due to over-provisioning
Solution Approach 1:
The patent merges redundancy resources across multiple virtual networks by implementing a shared pool of backup physical resources. Instead of dedicating separate backup resources to each virtual network, the system combines redundancy resources into a common pool that serves multiple virtual networks simultaneously, thereby improving resource utilization while maintaining reliability guarantees.
Solution Approach 2:
The patent makes physical resources universal by enabling backup resources to serve multiple functions and multiple virtual networks. A single backup physical resource can assume the role of different virtual resources across multiple virtual networks depending on failure scenarios, transforming dedicated redundancy into multi-functional shared redundancy that reduces overall resource requirements.
2Reliability
If redundancy resources are allocated to each virtual network individually, then reliability is ensured, but device complexity increases
Solution Approach 1:
The patent introduces a resource allocation manager as an intermediary layer between virtual networks and physical resources. This mediator handles the complexity of managing shared redundancy resources, allocating backup resources dynamically based on actual failures rather than pre-assigning dedicated backups to each virtual network. The intermediary abstracts the complexity from individual virtual networks while maintaining reliability through centralized coordination.
3Reliability
If more physical resources are provisioned for virtualized infrastructure, then reliability improves, but resource allocation efficiency deteriorates
Solution Approach 1:
The patent implements dynamic resource allocation where backup physical resources are not statically assigned to specific virtual networks but are dynamically allocated based on actual failure events. The system maintains a pool of standby resources that can be rapidly assigned to any virtual network experiencing failures, optimizing resource utilization while ensuring reliability. This dynamic approach replaces static over-provisioning with on-demand resource allocation.
