Embodiment 4

[0087] Such as image 3 As shown, the stream resource management system includes a stream resource management device 301, a session management device 303, and stream service devices 303a, 303b, and 303c.

[0088] The realization of stream resource management can be divided into the process of management and maintenance according to the report of the stream service device, and the process of resource allocation according to the request of the session management device.

[0089] Among them, the process of management and maintenance according to the report of the streaming service device is as follows:

[0090] Each stream service device periodically reports load status information. The load situation information includes load amount information and streaming service device status. The message format of the sending load situation is shown in Table 1. NEload represents the load situation of the streaming service, that is, the load amount information, where the load amount information is...

Abstract

The invention discloses a method, device and system for achieving flow resource management. The method comprises the steps that a flow resource on-demand message of a session management device is received by a flow resource management device and the flow resource on-demand message comprises a requested bandwidth; according to the current load of all flow service devices, one flow service device with the smallest current load and the normal service state is selected by the flow resource management device; whether the sum of the current load of the flow service device with the smallest current load and the normal service state and the requested bandwidth in the flow resource on-demand message is larger than the largest load of the flow service device is judged by the flow resource management device; if the answer is positive, the flow resource on-demand message sent by the session management device is refused by the flow resource management device; if the answer is negative, a flow resource distribution result is returned to the session management device by the flow resource management device. According to the method, device and system for achieving flow resource management, avoidance of over load of the currently-selected flow service device is guaranteed, and therefore the stability of operation of the system is guaranteed.

Description

Technical field [0001] The present invention relates to the video on demand field of the Next Generation Broadcasting Network (NGB), in particular to a method, equipment and system for implementing stream resource management. Background technique [0002] With the large-scale advancement of the integration of radio and television networks and the increasing public demand for on-demand, the next-generation broadcast and television network video-on-demand system needs to meet the needs of multi-screen terminals, support large-scale and distributed deployment, unified frequency resource management, and high service quality QoS (Quality of Service) guarantees, operational and manageable operational requirements. [0003] The NGB video-on-demand system includes at least a streaming service device (Streaming Server, SS), a session management device (Session Manager, SM), and a video stream resource management device (Video stream Resource Management, VRM, also known as a streaming resour...
