Stateless Network Service Management via Centralized Engine
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network systems face inefficiencies in managing access to remote network services without overutilizing hardware resources, as they often require maintaining state information across multiple access points, which can lead to memory and processing burdens.
Innovation Solution
Implementing a stateless network service management system that allows user devices to access remote network services by interrogating remote devices for available services without maintaining state information at access points, using a network service management engine to configure access parameters and facilitate connections across different VLANs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If network access devices maintain state information for remote network services, then service access management is simplified, but memory requirements and processing burdens increase
Solution Approach 1:
The patent extracts the state information maintenance function from network access devices and relocates it to a centralized network service management engine. This allows access devices to operate statelessly, reducing their memory requirements while the management engine handles service state information centrally, resolving the contradiction between simplified management and reduced memory usage.
Solution Approach 2:
The network service management engine acts as an intermediary between user devices and remote network services. It receives service requests, formulates queries, obtains access parameters, and configures user devices without requiring access devices to maintain state information, thus simplifying access management while keeping memory requirements low.
2Reliability
If network access devices maintain state information for remote network services, then service connectivity is ensured, but device complexity increases
Solution Approach 1:
The patent removes state maintenance functionality from network access devices, making them simpler forwarding elements. The management engine assumes responsibility for tracking service states and managing connectivity, thereby reducing access device complexity while ensuring reliable service connectivity through centralized management.
Solution Approach 2:
The network service management engine serves as an intermediary that handles the complexity of service connectivity management. It formulates service queries, obtains access parameters from remote devices, and configures user devices appropriately, ensuring reliable connectivity without burdening access devices with complex state management logic.
3Reliability
If state information is maintained at all access points, then service access control is improved, but resource utilization efficiency decreases
Solution Approach 1:
The patent merges the distributed state maintenance functions of multiple access devices into a single centralized management engine. This consolidation maintains access control capabilities through centralized authorization while eliminating redundant state information storage across the network, thereby improving resource utilization efficiency without sacrificing access control effectiveness.
Solution Approach 2:
The patent extracts state maintenance responsibilities from individual access devices and concentrates them in the network service management engine. This allows access devices to function as simple forwarding elements, improving resource utilization, while the centralized engine maintains comprehensive access control through unified state management.

AI summary
In various systems and methods, there can be received a request for a network service. A query for the network service can be formulated based on the request. A remote access device can be instructed to interrogate remote devices coupled to the remote network access device for the network service. Access parameters related to the network service can be received in response to the interrogation. The user device can be configured to access the network service based on the access parameters.
