QoS Connection Synchronization Between Bearer Network Resource Managers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Diff-Serv models in communication networks lack a mature solution for synchronizing resource requests and managing QoS connections between bandwidth brokers, leading to unreliable transmission quality and resource management.
Innovation Solution
Establishing QoS connections between bearer network resource managers through a method that includes creating connections, negotiating QoS information, and managing resources, with mechanisms for resource synchronization and maintenance, such as Keep Active timers and handshake messages, to ensure reliable QoS resource control message transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If Diff-Serv model with independent bearer control layer is used to manage network resources, then resource management capability is improved, but transmission reliability deteriorates due to lack of resource synchronization mechanism between bandwidth brokers
Solution Approach 1:
The patent implements a feedback mechanism through handshake messages between bandwidth brokers. When a bandwidth broker receives a resource request, it sends a handshake message to confirm resource availability and allocation status. This feedback loop ensures that resource synchronization is maintained across the network, resolving the reliability issue while preserving the automated resource management capability of the Diff-Serv model.
2Ease of operation
If SIBBS signaling is used for resource requests between bandwidth brokers, then resource request processing is simplified, but resource synchronization cannot be achieved
Solution Approach 1:
The patent introduces an intermediary mechanism in the form of handshake messages that mediate between bandwidth brokers during resource requests. These handshake messages act as intermediaries to confirm resource allocation and maintain synchronization, enhancing the basic SIBBS signaling functionality without complicating the resource request processing flow.
3Reliability
If QoS connections are established between bearer network resource managers, then message transfer reliability is improved, but system complexity increases
Solution Approach 1:
The patent applies preliminary action by establishing QoS connections between bearer network resource managers before actual resource requests are processed. This pre-establishment of reliable communication channels ensures that subsequent message transfers are reliable, while the connection management overhead is incurred only once rather than with each transaction.

AI summary
A method is disclosed for providing reliable transmission Quality of Service (QoS) in communication network, in which a QoS connection is established between bearer network resource managers in bearer network control layer, and maintenance management mechanism is well established in terms of the QoS connection. Various QoS resource control messages can be carried through this established QoS connection, so that request of service bandwidth application of the user and the result thereof, as well as the path information allocated by bearer network resource managers can be transferred. The disclosed method is reliable and easy to implement and maintain, with good controlled quality, and can implement resource synchronization between bearer network resource managers. Therefore, implementation of the disclosed method makes it more convenient to manage resources of bearer network uniformly, and provides technical support on guaranteeing transmission reliability of important services.
