Embodiment 100

[0168] ●The cost performance advantage of the embodiment of the present invention is 100 times that of IP Internet

[0169] ●Implementation method for developing high-quality symmetrical TV without interfering with existing IP Internet services

[0170] Especially in the backbone network with large traffic, computer files and streaming media share one optical fiber through different wavelengths. If it is necessary to unify to a single network, such as an access network, then it should unify computer files to a video streaming network. The embodiment of the present invention provides a complete solution for transparently carrying the IP Internet.

[0171] Separate processing of streaming media and files is only the first step. How to ensure independent streaming media network quality?

[0172] As mentioned earlier, the PSTN telephone network adopts a strict synchronization mechanism, and when the traffic is 100% full, there will be no network congestion. Theoretically speaki...

Abstract

The invention provides a flow-control-based data transmission method, a flow-control-based exchanger, a node server and a flow-control-based communication system to solve the problem that a current IP network cannot ensure the quality of network transmission. The method comprises the following steps of: aiming at each service application, acquiring flow control information by the exchanger, wherein the flow control information comprises a transmitting time interval and the size of transmitted data; receiving a data packet by the exchanger, and placing the data packet into a packet buffer queue; and polling the packet buffer queue by the exchanger, taking a packet from the packet buffer queue according to the flow control information, and transmitting the packet. The invention can realize accurate flow control and is suitable for multimedia transmission, and the transmission quality is ensured.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a data transmission method based on flow control, a switch based on flow control, a node server and a communication system based on flow control. Background technique [0002] Communication networks, including the Internet, enable the exchange of information and other information resources between different individuals and institutions. Networks usually include technologies such as access, transmission, signaling, and network management. Such techniques have been described extensively in the literature. These are summarized in: Telecommunications Convergence by Steven Shepherd (McGraw-Hill, 2000), The Essential Guide. to Telecommunications, Third Edition by Annabel Z. Dodd (Prentice Hall PRT, 2001 ), or Communications Systems and Networks, Second Edition by Ray Horak (M&T Books, 2000). Past advances in these technologies have substantially increased the speed, quality, a...
