Endpoint Table Reallocation for Server Availability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In enterprise systems, particularly in healthcare, the allocation of service endpoints to servers is challenging when one server becomes non-operational, leading to service endpoint unavailability and disruption in processing requests.
Innovation Solution
An endpoint table is maintained to specify the allocation of service endpoints to server systems, allowing for reallocation of endpoints from a non-operational server to operational ones, ensuring continuous processing of requests and high availability by updating the table to direct packets to the newly allocated server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If service endpoints are allocated to multiple servers for scalability and higher throughput, then system productivity and reliability improve, but system complexity increases due to the need for dynamic reallocation and endpoint table management
Solution Approach 1:
The patent introduces an endpoint table as an intermediary data structure that decouples the complexity of service endpoint allocation from the server processing logic. The endpoint table serves as a centralized registry that maps service endpoints to their allocated servers, allowing the system to manage complex allocations without increasing the complexity of individual server operations. This intermediary layer enables scalable throughput while containing system complexity in a manageable central component.
2Reliability
If service endpoints are statically allocated to servers, then system complexity is reduced, but system reliability deteriorates when servers become non-operational
Solution Approach 1:
The patent implements dynamic service endpoint allocation where the endpoint table can be updated in real-time to reflect changes in server operational status. When a server becomes non-operational, the system dynamically reallocates its service endpoints to other available servers by updating the endpoint table entries. This dynamic approach maintains high service availability while managing reallocation complexity through systematic table updates rather than complex redistribution algorithms.
Solution Approach 2:
The system performs preliminary actions by maintaining the endpoint table in advance, which pre-establishes the mapping between service endpoints and servers. This preliminary structure allows for rapid reallocation when failures occur, as the system only needs to update existing table entries rather than compute new allocations from scratch. The endpoint table serves as a pre-prepared allocation framework that enables quick reliability recovery without complex real-time computation.
3Reliability
If service endpoints are reallocated dynamically upon server failure, then system reliability is maintained, but loss of time occurs during the reallocation process
Solution Approach 1:
The endpoint table is maintained in advance as a pre-configured allocation structure, allowing the system to perform rapid updates when server failures occur. Rather than computing allocations in real-time during failures, the system leverages the pre-established endpoint table framework to quickly redirect service endpoints to alternative servers. This preliminary structuring minimizes reallocation time while maintaining service continuity.
Solution Approach 2:
The system updates only the specific endpoint table entries affected by server failures rather than performing a complete system-wide reallocation. This partial action approach focuses computational effort only on the necessary changes, significantly reducing reallocation time. By updating individual endpoint mappings rather than reconstructing the entire allocation system, the patent achieves rapid service continuity with minimal time loss.

AI summary
An aspect of the present disclosure provides for allocation of service endpoints to servers. In an embodiment, an endpoint table is maintained to specify currently allocation of respective service endpoints to corresponding server systems. Upon occurrence of a condition requiring reallocation of a first set of service endpoints currently allocated to a first server system, the first set of service endpoints are reallocated among the operational server systems (typically the server systems other than the first server system). The endpoint table is accordingly updated in accordance with the reallocation. When a packet is thereafter received directed for delivery to a target service endpoint, the packet is delivered to one of the operational server systems, which is indicated as being allocated the target service endpoint in the updated endpoint table.
