Interworking control device and method for ABR / ABT transmission capability interworking of asynchronous transmission mode public network

摘要

The present invention relates to an effective bit rate (ABR) input traffic having different resource management (RM) cell structures and flow control schemes when only asynchronous transfer mode block transfer (ABT) flow control is implemented in an asynchronous transfer mode (ABR / ABT) transmission capability for interworking with an effective bit rate / asynchronous transmission mode block capable of receiving an asynchronous transmission mode block transmission (ABT) is required to pass through the implemented public network, a transmission capability interoperability mechanism capable of accommodating the effective bit rate traffic is required, and a block cell ratio of the control traffic according to the change of the allowable cell ratio of the temporally variable effective bit rate source Therefore, in the present invention, an interworking unit is provided with an effective bit rate for traffic flow control Source and virtual source functions, terminating the effective bit rate forward resource management cell input from the external effective bit rate switching system, transmitting the effective bit rate reverse resource management cell to the effective bit rate switching system, (ABR / ABT) by performing asynchronous transmission mode block transmission traffic control by generating a resource management cell which requests the block cell rate band of the asynchronous transmission mode block transmission traffic according to the extracted allowed cell ratio value, Interoperability can be performed.
