Embodiment Construction

[0035] The core of the present invention is in the IP network based on ASON network, utilizes content data server CS or content distribution entity to send multimedia business (being media data piece) in rotation directly to each district media server through the two-layer interface link, then, Then, the media server in the community distributes the multimedia service to each user in the form of stream, so that the transmission of the multimedia service that can provide QoS guarantee is realized based on the ASON network.

[0036] The IP network is built on the ASON network, that is, the transmission network on the third layer is an IP network, and the transmission network on the second layer is an ASON network.

[0037] The system of the present invention is shown in FIG. 1 , and the functions of the entities involved in the present invention in FIG. 1 will be described separately below.

[0038] Content data server CS: a large number of media data files are placed on the CS,...

Abstract

The invention relates to a system of media data real-time transmission based on the automatic exchange optical network and relative method. In the IP network constructed based on ASON network, the invention uses content data server and the content distributor, via the two-layer interface chain circuit, to transmit the multimedia service (media data) to the media server of each section in turn; then the media server distributes said multimedia service in flow format to each user to realize the transmission of multimedia service with QoS confirmation based on ASON network. Since the chain circuit service quality is in telecommunication grade provided by the ASON, the invention can avoid the problems that transmitting on the IP network to meet the demand of real-time display, when the order number and the band width meet the demand.

Description

technical field [0001] The invention relates to the technical field of optical network communication, in particular to a technology for real-time transmission of media data based on an automatic switching optical network. Background technique [0002] With the rapid development of network communication technology, the demand for multimedia services such as video on demand on the Internet is becoming more and more obvious. The rapid improvement of Internet backbone and access network bandwidth provides a technical basis for the development of multimedia services. However, the Internet uses IP network technology at the network layer. The IP network is essentially a Best Effort (best effort) shared digital network. It implements connectionless, packet switching, and statistical multiplexing for data transmission based on the IP protocol. For services such as voice and real-time multimedia audio / video streaming, end-to-end guaranteed QoS (Quality of Service) cannot be provided....
