Abstract:
1. An ATM-port module for an ATM-node having an Ethernet switch, the ATM-port module comprising: an ATM-controller; an Ethernet-switch interface connecting the ATM-controller to the Ethernet switch, the Ethernet-switch interface having an Ethernet encapsulating-unit for encapsulating ATM cells processed by the ATM-controller into Ethernet packets for transmission to the Ethernet switch, and an Ethernet decapsulating-unit for extracting ATM cells from Ethernet packets received from the Ethernet switch, a segmentation-and-reassembly unit; and a buffering-and-scheduling unit for providing a processed enlarged-ATM-cell, the processed enlarged-ATM-cell including destination information, to the Ethernet encapsulating-unit when an indication flag indicates that an ATM port is a destination port of the enlarged ATM-cell; and providing the processed enlarged-ATM-cell to the segmentation-and-reassembly unit when the indication flag indicates that an Ethernet port is the destination port of the enlarged ATM-cell.
