Technical Details for Cisco 12406

Cisco 12406 ... profitable and competitive. The Cisco 12000 Series offers flexible configurations and a superior modular, distributed architecture, cost reduction and investment protection. The Cisco 12000 Series' distributed architecture delivers the industry's highest scalability, performance, only guaranteed priority packet delivery, cost reduction and best investment protection, providing the tools needed by service providers to accelerate their service velocity and eliminate their barriers to profitability. The Cisco 12406 Internet Router features a 120 gigabits-per-second (Gbps) switching capacity for six 10 Gbps (full-duplex) slots in a quarter-rack configuration delivering a high quantity of bandwidth while helping service providers control real estate costs.

The Cisco 12000 Series distributed architecture delivers high quality services and bandwidth through its distributed packet forwarding and memory, and crossbar matrix switch. Innovative virtual output queuing (VOQ) technology ensures that the switch fabric experiences no head-of-line (HOL) blocking while an enhanced clock scheduler guarantees that all line cards get equal access to the fabric. Extensive use of high-performance application-specific integrated circuits (ASICs) support line-rate forwarding with minimal latency of real-time traffic while the switch fabric handles replication of multicast traffic in the hardware, providing a high level of performance. Advanced quality of service (QoS) features such as Weighted Random Early Detection (WRED) and Modified Deficit Round Robin (MDRR) guarantee that priority packets are delivered and customer service level agreements (SLA) are met. To enable the delivery of services, the Cisco 12406 Internet Router supports Cisco IOS Software - a comprehensive software suite of features needed to support today's networks and tomorrow's next-generation services. Proven in customer networks and known by network engineers worldwide, Cisco IOS Software is a necessary building block in IP+Optical networks. The Cisco 12406 delivers the bandwidth and services needed to accelerate service velocity while controlling costs and offering investment protection - helping service providers to become more profitable.
