Abstract

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.
