Abstract

TeraNet is an experimental optical network which offers user access rates as high as one Gigabit per second (Gbps). The network provides both circuit switching and ATM packet switching in a hierarchical fashion. Circuit switching is accomplished through the use of tunable optical WDMA/Subcarrier-FDMA channels. An overlaid multihop technique that uses a sub-set of the underlying optical circuits, constructs a packet switching environment. Circuit switched services interface to the passive optical 'ether' through Media Interface Units (MIU). A 3 X 3 switching node called Network Interface Unit (NIU), with 1 Gbps capacity per port, is used as an ATM access port to the packet switching layer. The ATM overlaid network incorporates a traffic control architecture that supports multiple traffic classes. Output buffers and bandwidth are shared according to a resource allocation concept called Asynchronous Time Sharing (ATS).
