Abstract
The router consists of two-way channel interface and monoway channel transmitting ports installed in the router data bus between the data source and the terminals. During transmission, the router with several monoway channels completes routing selection in the monoway channels of itself. The present invention has high transmission efficiency in the case of large data amount difference between the upstream and the downstream channels. Using the present invention in data transmission costs only 1/10-1/5 compared with available technology.
Description
The present invention relates to a kind of router and transmission method thereof, especially a kind of router with several monoway channels and transmission method thereof belong to digital communicating field.
At present in digital communicating field, traditional router is that two-way channel interface and data/address bus formation are installed between information source and terminal equipment, and the miscellaneous equipment on the corresponding cable that links to each other with it of the interface of several routers is divided into several network segments or subnet.Route is actually the path parameter (normally according to setup parameters such as shortest path or expenses) that indicates according to the routing iinformation bag, by the instrument of router intelligence according to a certain parameter selection information transmission path, Route Selection is carried out between several network segments or subnet.This traditional router and transmission method thereof can only be suitable for the two-way channel transmission, and the transmission data efficiency is low, and the cost height.
The objective of the invention is to design a kind of efficiency of transmission height, and low router with several monoway channels and the transmission method thereof of transmission cost.
For achieving the above object, the scheme that the present invention taked is: a kind of router with several monoway channels is the two-way channel interface to be installed and one group of one-way channel is installed to send a mouthful formation on router data bus between information source and the terminal equipment.Generally speaking, be to constitute by one or more unidirectional down channels, one or two two-way channels.During transmission, router with several monoway channels is by selecting (comprising the down channel in the two-way channel) in the enterprising walking along the street of a plurality of one-way channels own.When client desires to call certain file, send an order by customer terminal equipment and pass to information source by two-way channel, this order breaks into many file bags with desiring to call file, each file bag is divided into many frames again and passes on the router with several monoway channels, on how unidirectional router, pass through certain parameter, for example: the information flow-rate parameter, communications protocol, the channel expense, desired rate, signal service quality, data type, file type, frame format, parameters such as verification mode are selected one-way channel, select the data of one-way channel before transmission, may carry out agreement or frame format conversion, also may not carry out conversion.Data enter in the computer of terminal equipment after closing up by one-way channel incoming terminal tables of equipment, and by frame composing document bag, file bag recomposition file has been finished whole transmission course.
Efficiency of transmission height of the present invention particularly under the upstream and downstream channel data volume differs bigger situation, has really been realized non-equilibrium transmission; Use router with several monoway channels of the present invention and method thereof to carry out transfer of data, cost is the 1/10-1/5 of prior art cost.
Now the invention will be further described in conjunction with the accompanying drawings:
Accompanying drawing 1 is router with several monoway channels structural representation of the present invention;
Accompanying drawing 2 is connected block diagram for the present invention with relevant device;
Accompanying drawing 3 is transmission method flow chart of the present invention;
Accompanying drawing 4 is used for broadcasting and television network transmitting data stream journey figure for the present invention.
As shown in Figure 1, a kind of router with several monoway channels is two-way channel interface 9 to be installed on the router data bus 10 between information source and the terminal equipment and one group of one-way channel interface, 3 formations also are installed on data/address bus 10.Generally speaking, be to constitute by one or more unidirectional down channels, one or two two-way channels.During transmission, router with several monoway channels is by selecting (comprising the down channel in the two-way channel) in the enterprising walking along the street of a plurality of one-way channels own.As shown in Figure 2, when terminal equipment 6 desires to call certain file, send an order by terminal equipment 6 and pass to information source 1 by two-way channel 7, this calls file and is broken into many file bags, each file bag is divided into many frames again and passes on the router with several monoway channels 2, as shown in Figure 3, on router with several monoway channels 2, pass through certain parameter, for example: the information flow-rate parameter, communications protocol, the channel expense, desired rate, signal service quality, data type, file type, frame format, verification modes etc. are selected one-way channel, select the data of one-way channel before transmission, may carry out agreement or frame format conversion, also may not carry out conversion.Data enter in the computer of terminal equipment by single closing in 5 of one-way channel 4 incoming terminals 6, and by frame composing document bag, file bag recomposition file has been finished whole transmission course.For example, as shown in Figure 4, sending an order by terminal equipment passes to information source by two-way channel and calls a broadcast files, this calls file and adopts the multicast agreement to break into many file bags to pass on the router with several monoway channels, router is selected one-way channel broadcasting according to the agreement (as multicast agreement, DVB Radio Broadcasting Agreements, ICP/IP protocol) of file, close up through the list that one-way channel passes to each terminal from the single-shot mouth of how unidirectional router, enter then in the computer of terminal.Two-way channel 5 can be computer local network, dialing network, X.25, ISDN, DDN, ATM, frame relay etc.One-way channel 4 can be certain bar physical channel, as the One-to-All Broadcast cable in wired television network; Also can be according to the some channels in frequency division or the time division circuit,, can be divided into a plurality of one-way channels again according to time-division or frequency sharing circuit as the cable of wired television network; One-way channel 4 can also be certain channel in yard parallel circuit or the some channels in the wavelength-division circuit.
