OVERVIEW

IP networks have become an important communication infrastructure. Such services as virtual private networks (VPNs) for enterprises, electronic-commerce, and voice over IP are being deployed over them. Accordingly, the volume of traffic carried over IP networks is growing dramatically. To support this growth, higher speed line-interfaces and larger capacity switches will be the key components of next-generation IP network nodes. Carrier-class reliability and quality of service guarantees are strongly demanded as well for mission-critical business support. In this paper, we discuss the next-generation IP network architecture and the major requirements for the terabit IP nodes needed in backbone networks of the next generation. A distributed routing-processor architecture, scalable large crossbar switch, and high-speed line interface are the key technologies of terabit IP nodes.
