The Cisco 12000 Series delivers capacity and services with its fully distributed forwarding architecture and maximum efficiency crossbar switch fabric. The combination of the centralized scheduler and unique virtual output queuing (VOQ) technology maximizes the use of the switch fabric bandwidth, minimizes latency, and provides nonblocking performance. The Cisco 12816 Router uses the latest in high-performance application-specific integrated circuit (ASIC) technology to provide line-rate forwarding with an extensive feature set, while maintaining the strict jitter and latency required for real-time services. Offering a comprehensive set of quality-of-service (QoS), IP/Multiprotocol Label Switching (MPLS), and high-availability features, the Cisco 12816 Router can help ensure maximum bandwidth utilization and traffic differentiation while meeting even the strictest customer service-level agreements (SLAs).The Cisco 12816 Router uses Cisco IOS Software to deliver numerous service possibilities. Cisco IOS Software is the most widely deployed router operating system available today. It provides a comprehensive suite of IP/MPLS and high-availability features to enable today's networks and tomorrow's next-generation services.
