As more and more services become available on the Internet, carrier IP networks are becoming more of a social infrastructure. They and their nodes must thus support higher speeds, larger capacities, and higher reliability. This paper describes Hitachi's carrier IP network systems and how they fulfill these requirements. For backbone IP networks Hitachi provides a large-capacity, multi-functional IP node, the GR2000, and is developing a next-generation tera-bit-class IP node architecture. For backbone and metropolitan optical networks, Hitachi provides SONET/SDH and DWDM transmission systems.
