Server Instance Allocation via Operational Parameter Eligibility Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing load balancing techniques in server computers often allocate server instances in a round robin manner, making it difficult to establish application instance sessions on selected server instances with specific hardware or firmware capabilities, leading to inefficient resource utilization.
Innovation Solution
A method for allocating server instances based on operational parameters, including unique identifiers, IP addresses, and MAC addresses, which analyzes eligibility for execution and queues requests if a server instance is overloaded, allowing for reevaluation during a timeout period and reallocating if capabilities change.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If round robin allocation is used for server instances, then allocation simplicity is improved, but resource utilization efficiency deteriorates
Solution Approach 1:
The patent changes the allocation parameter from simple sequential indexing (round robin) to a composite parameter that includes server instance capabilities, current load status, and application instance requirements. This allows the system to select server instances based on matching capabilities and available resources, thereby improving resource utilization efficiency while maintaining allocation simplicity through automated parameter-based selection.
2Reliability
If server instances are selected based on specific capabilities, then execution eligibility is improved, but allocation complexity deteriorates
Solution Approach 1:
The patent performs preliminary actions by pre-registering server instances with their capabilities and pre-defining application instance requirements. This allows the system to quickly match capabilities with requirements without complex real-time analysis, improving execution eligibility while keeping allocation complexity manageable through pre-established matching criteria.
Solution Approach 2:
The patent introduces an intermediary matching mechanism that mediates between server instance capabilities and application instance requirements. This intermediary layer simplifies the allocation process by handling the complexity of capability matching automatically, thereby improving execution eligibility without exposing the complexity to the allocation logic.
3Productivity
If server instances are overloaded, then request handling capacity is improved, but session establishment reliability deteriorates
Solution Approach 1:
The patent implements dynamic load monitoring and adaptive allocation where server instance load status is continuously tracked. When a server instance becomes overloaded, the system dynamically adjusts allocation decisions to avoid assigning new application instances, thereby maintaining session establishment reliability while allowing request handling capacity to scale with available resources.

AI summary
Example techniques for allocating a candidate server instance for execution of an application instance are described. In an example, a request for allocation of a candidate server instance from multiple server instances is received. The request for allocation of the candidate server instance comprises allocation parameters to uniquely identify the candidate server instance from the plurality of server instances. Subsequently, operational parameters of the candidate server instance are analyzed to determine eligibility of the candidate server instance for execution of the application instance. The candidate server instance is subsequently allocated for execution of the application instance based on the eligibility.
