Service Provisioning via Virtual Resource Reservation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing service provisioning process in communication networks is inefficient due to the requirement for all resources to be installed and available before a service can be activated, leading to delays and increased costs, especially in optical DWDM networks where resources may be used for other services or not yet installed, causing significant delays in service availability.
Innovation Solution
A method that allows resources to be reserved and utilized before they are available for productive use, enabling service activation as soon as the necessary resources are installed and available, by creating, reserving, and allocating virtual or physical resources, even if they are not yet installed or available, using a system database to manage and configure these resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all resources are required to be installed and available before service activation, then service reliability is ensured, but service provisioning time increases significantly
Solution Approach 1:
The patent applies preliminary action by creating virtual representations of resources in the system database before the physical resources are actually installed. This allows service provisioning processes to begin in advance, reserving resources and preparing service configurations ahead of time. When resources are eventually installed, the service can be activated quickly since all preparatory work has already been completed, thus reducing provisioning time while maintaining reliability through the virtual resource reservation mechanism.
2Productivity
If resources are reserved before installation, then service provisioning speed increases, but resource availability for other services decreases
Solution Approach 1:
The patent uses copying by creating virtual copies of physical resources in the system database. These virtual resources are representations that allow service provisioning to proceed without occupying actual physical resources. When multiple services compete for the same physical resource, the virtual copying mechanism allows efficient resource allocation and scheduling, enabling fast service provisioning while maintaining flexibility in resource distribution across different services.
3Ease of manufacture
If equipment installation is spread over several days or weeks, then proper resource allocation is achieved, but service activation delay increases
Solution Approach 1:
The system performs preliminary actions by creating virtual resource entries and initiating service provisioning processes before physical equipment is installed. The system can reserve resources, configure service parameters, and prepare all necessary arrangements in advance. This way, when equipment installation is spread over multiple days or weeks, the service provisioning work continues concurrently without waiting for physical resources, significantly reducing the overall service activation delay while maintaining efficient resource allocation.
4Reliability
If resources are not reserved in advance, then resource availability is maintained, but service provisioning requires additional planning cycles
Solution Approach 1:
The patent implements copying by creating virtual representations of resources in the system database before physical resources are allocated. These virtual copies allow the service provisioning system to reserve and allocate resources without actually consuming physical resources. This mechanism ensures that physical resource availability is maintained for other uses while enabling efficient service provisioning through virtual resource reservation, eliminating the need for additional planning cycles.
