Abstract
An SVC is established via an ATM switch port, which includes multiple virtual paths (VPs), by associating multiple virtual user-to-network interfaces (UNIs) to each of the VPs. Each of the VPs includes multiple virtual circuit (VC) ranges, each of which corresponds to a different virtual UNI. Each VC range includes at least one VC for control and at least one VC for data transfer. Associating the virtual UNIs to each of the VPs includes mapping each virtual UNI to a corresponding VC range within a VP based on a virtual path index (VPI)/virtual channel index (VCI) of the virtual UNI initially received by the ATM switch port.
