Working Device for mapping a Circuit Network Data and Asynchronous Transfer Mode Network Data in a ATM Network and The Method Thereof

摘要

Vertical frame buffer to store data that relates to; (ATM Asynchronous Transfer Mode) network, network information and the asynchronous transfer mode interworking unit and the interworking for the mapping between the network information in the method, the inlet or outlet to the network (the present invention is the Asynchronous Transfer Mode by an interrupt to the configuration between the HCB) parts of data format conversion, and generate during frames received / transmitted in the network connection; Vertical frame buffer; VFB) and the horizontal cell buffer (horizontal cell buffer flowing into the ATM network, or stores the data flowing out of by differentiating the operation of the control unit depending on the availability of and controls parts of the data format converted by the control unit operative to perform a conversion between network data and ATM network data, the data format conversion (Channel Associate Signaling) CAS information, insertion of the CAS information and it is possible to facilitate the extraction operation, the assembly in the next / splitting By in predicting the type of emulation circuit structure to a character asynchronous transfer to improve the data rate conversion mode network interworking method is presented for the mappings between the network information, and Asynchronous Transfer Mode network information.
