Static program distribution and service method in cluster type stream media system

Abstract

According to favoured degree of static program (SP), this method divides SP into several levels and determines the node layer to which a certain level program is distributed, the higher favoured degree of SP level the lower node layer to be sent. According to the SP level and the node layer to be sent, the business supervision system issues programs to the center node (CN). CN distributes programs to numerous level of edge nodes. Nodes preserve these programs. When ordering a program, the user end (UE) builds a link with the aim flow-media server (AFS) preserving this program and asks to play. AFS reads data of this ordered program and sends the corresponding code flow to UE. This invention uses reasonably the hardware resource and offers a hi-efficiency program dispatching mode and user dispatching mode.

Description

technical field [0001] The invention relates to a cluster streaming media networking method, in particular to IPTV applications in the field of multimedia communication, mobile streaming media applications and methods for distributing and serving static programs in video monitoring. Background technique [0002] For applications related to streaming media, under the current technical level and the demand for a large number of users, a server cluster solution is generally used to solve the problems of a large number of users and a large user area. The so-called cluster streaming media system is a networking architecture in which the streaming media server system is divided into multiple nodes. These nodes are generally divided into central nodes and multi-level edge nodes. It is also possible that each node is in a parallel relationship. The composition of each node is shown in Figure 1, including a group of servers and a group of storage devices, wherein the server includes ...

Problems solved by technology

[0006] The disadvantages of this method are: 1. Reasonable sharing is not achieved, and storage resources will be greatly wasted; 2. The scheduling algorithm is simple, resulting in large resource consumption, unreasonable user scheduling, and can not be more complete load balancing

[0008] This method also has some disadvantages: 1. Static programs need to be fragmented before processing, and the internal media format is a proprietary media format; 2. The scheduling algorithm is quite complicated, which in turn causes consumption of backbone network bandwidth and system instability; 3. When expanding the capacity, the content of the program fragments needs to be re-arranged reasonably; 4. The system architecture is tightly coupled, and the business management system and the media service system are not clearly separated. The switching of different file fragments in the service process even requires The terminal implements private protocol participation
