Cisco MGX 8900 Series Switches
The Cisco MGX 8900 Series Multi-service Switch is a high-end multi-service switch designed to scale multi-service networks to OC-192c/STM-64. The Cisco MGX 8900 Series offers service providers the greatest level of choice and control over extensions of existing infrastructure as well as providing a seamless path to future services.
Multiple, simultaneous control planes support unmatched flexibility and scalability in deploying, managing, and modifying a complete range of ATM and Multiprotocol Label Switching (MPLS).
Based on the industry's most extensible architecture, the Cisco MGX 8950 Multiservice Switch provides the greatest flexibility in service provider networks. Multiple, simultaneous control planes support unmatched flexibility and scalability in deploying, managing, and modifying a complete range of ATM and Multiprotocol Label Switching (MPLS).
The Cisco MGX 8950 Multiservice Switch supports carrier-class reliability, availability, and serviceability with an evolutionary architecture using the Cisco QuadNonstop switching fabric set designed to meet the demands of 10-Gbps ATM traffic.
The Cisco Europa chipset guarantees continuous and full use of 10 Gbps per slot so that all queues are used at the maximum line rate. The Cisco Europa chipset supports available bit rate (ABR) VS/VD traffic management at a 10-Gbps line rate. This results in superior control of jitter and latency at the full 10-Gbps line rate, providing the most reliable and flexible support for traffic demands ranging across voice, bursty IP flows, and delay- and jitter-sensitive applications
