| 摘要 |
The present invention relates to an Asynchronous Transfer Mode(ATM) network adaptor for the simultaneous processing of the multi-channel traffic, and includes an R-interface(RIF) means composed of a plurality of first interface means, which output the CBR traffic according to their token signal indicating a point of time occupying the bus or in the case of having the same header address as its own, after receiving the external CBR traffic, and composed of a plurality of second interface means which receive the external VBR traffic and also output it to the external; a Multipled Traffic bus(MT-bus) is connected to the first interface means, being used for transmitting multiplexed channels by providing constant bandwidth necessary for the CBR traffic transmission; a system bus is connected to the first and second interface means, and used for transmitting not only VBR traffic of the second interface means but also the resource control signal of the system; and an ATM Network Interface(ANI) means used for transmitting the CBR traffic from the first interface means to the ATM network over said MT-bus means after receiving a token signal from the first interface means and also contrariwise, and for transmitting the VBR traffic from the second interface means to the ATM network and also contrariwise. The present invention can process the CBR and VBR traffic simultaneously as mentioned above, by which we can establish the environment of the recently popularized multi-media communication. Therefore, the high priced communication line having the characteristic of the broadband can be used effectively by utilizing the present invention.
