Abstract

With the rapid development of the Internet and multimedia technology, more and more people demand access to multimedia information through the network, and video-on-demand, distance learning, press releases, and other multi-point communications business will become the focus of competition of a new round of operations. It has been developed in the network platform with a variety of business, such as E-MAIL, TELNET, FTP, WWW business, these are point-to-point data transmission; while people want to open the video conferencing on the Internet network, listen to live music , watching the live broadcast, etc., these point-to-multipoint or more point-to-multipoint data transmission, video transmission network bandwidth problem more prominent. Such as when n IP address simultaneously receive Internet Multimedia video stream, set required for each video stream and the transmission bandwidth of 1.5 Mbps, the bandwidth required for n × 1.5 Mbps network structure by now, will also bring the network delay intolerable when and jitter. In order to better solve these problems, this article will propose appropriate solutions for the existing network optimization techniques. This paper explore video streaming technology, QoS, IP multicast technology used in network and safeguards. Streaming media technology is a specialized for network multimedia information dissemination and processing of new technologies. The technique is a way to network dissemination and play at the same time the real-time mode, online audio and video, has become especially real-time audio and video transmission solutions. This article convection media key technologies are classified, and key technologies such as data compression / decompression, transmission protocols and digital rights management are introduced. How to improve the streaming quality of service QoS is a key problem now streaming technology development. In the field of multimedia, especially in the field of streaming media technology, it can not be ignored. Video streaming of real-time data related to network bandwidth, latency and packet loss have higher requirements, but is widely used IP network is a best-effort network, it does not provide any services for real-time multimedia quality assurance. Firstly to control the quality of service from two aspects: the sender to control sending traffic; reproduction in the data side by buffering mechanism to control the media synchronization. Then, starting from the congestion control and error control Qos control mechanisms explored in depth. IP Multicast technology has great advantages in multi-point video data transmission, when a site to multiple sites in the network to send the same video data, multicast technology can reduce unnecessary overlap sending with multiple points on point unicast compared to alleviate the burden on the system and network, improved user resources and network bandwidth utilization, greatly improve the real-time transmission of video data. The communication host whether the source site and the destination site using the same program of the points of the client and server, which has reciprocity. The multicast brought many new applications and reduce the burden of network congestion and server.
