Engineering Contradiction Analysis
1Measurement precision
If only basic network topology and bandwidth utilization status information are transmitted from transport layer FE to transport control layer FE, then the transmission protocol remains simple and basic resource admission control can be performed, but the resource admission control accuracy deteriorates and cannot support real-time services with specific delay and packet loss requirements
Solution Approach 1:
The patent extends the traditional single-dimensional bandwidth-based admission control to multi-dimensional control by adding traffic class information, service mode information, and QoS parameter status (delay, delay jitter, packet loss ratio) to the transmitted resource information. This dimensional expansion enables the transport control layer FE to perform comprehensive resource admission control that simultaneously considers bandwidth, delay, delay jitter, and packet loss requirements.
Solution Approach 2:
The patent changes the parameters being monitored and transmitted from basic topology and bandwidth utilization to include detailed QoS parameters such as delay, delay jitter, and packet loss ratio for each traffic class. This parameter transformation allows the admission control system to make decisions based on multiple quality dimensions rather than just bandwidth availability.
2Reliability
If comprehensive network resource information including traffic class and service mode information is transmitted, then accurate multi-dimensional resource admission control can be performed, but the information transmission complexity and data volume increase
Solution Approach 1:
The patent segments network resource information by traffic class, with each traffic class having its own service mode information and QoS parameter status. This segmentation allows the transport control layer FE to perform targeted admission control for different service types (e.g., real-time voice, video, data) based on their specific requirements, rather than using a one-size-fits-all approach.
Solution Approach 2:
The patent establishes a feedback mechanism where the transport layer FE continuously monitors and transmits the actual status of QoS parameters (delay, delay jitter, packet loss ratio) for each traffic class to the transport control layer FE. This feedback loop enables dynamic admission control decisions that adapt to changing network conditions and ensure service quality requirements are met.

AI summary
A method and device for transmitting network resource information data are provided by the present invention. The method for transmitting network resource information data includes: step 1, transmitting, by a transport layer function entity, the network resource information data including network topology and variation status information, network link bandwidth utilization status information to a transport control layer function entity; and step 2, the transport control layer function entity creating network resource status data according to the collected network resource information data, and performing resource admission control and path selection to a session according to the network resource status data, wherein, the network resource information data further comprises a traffic class and service mode information of the traffic class, resource and utilization status information of the traffic class. Therefore by using the present invention, the manner for performing resource admission control according to a single bandwidth parameter is changed and the admission control of the network resource and the resource distribution can be performed more comprehensively and exactly.
