The Internet is growing, and terabit routers are needed. We will discuss two scalable architectures, and their performances: the packet switch with input buffers based on a cross-bar fabric, and the packet switch based on a Clos fabric and load balancing. Both architectures provide non-blocking, and, therefore agile admission control for unicast and multicast traffic. They will be also shown to provide rate and delay guarantees to the sensitive applications.
