The Qos Of Real-time Transmission Of Multimedia Information

The technology of real-time communication of multimedia data is discussed in this paper. The quality of server of real-time communication of multimedia data is not easy to be meeted.The feature of multimedia data is must to be known for its real-time communication the main different feature from others is data quantity is large and real-time require, it is also difficult point, ibr real-time communication of multimedia data. The conception of quality of server, the require of the real-time communication of multimedia data for network is also need to be known.The compare of the different schedule algorithm of the IP packet in buffer is progressed to know their advantage and shortcoming. A new schedule algorithm is come out of them at the end of the paperThe source reservation protocol (RSVP) is need for real-time communication of multimedia data. RSVP is one of the send signal protocols. The process of RSVPincludes the build of link, the information of period send and the teardown of link.The buffer in router is full with the IP packets when router's process rate is lower than the input rate of the all ports of the router. Router will abort IP packet when buffer is full and the IP packet is coming in. the tail drop do not use the link enough with TCP/IP's slow start. The Random Early Detect (RED) is put forward to avoid the general synchronization.The IP QoS (quality of server) system structure is discussed in this paper, the known system structure includes Sub Bandwidth Management (SBM), integrated server system structure (IntServ), different server system structure (DiffServ), mutilprotocol label switch (MPLS), etc.
