The Cisco® MGX® 8950 Multiservice Switch scales service provider networks by providing 180 Gbps of redundant switching with up to 10-Gbps ATM interfaces. The Cisco MGX 8950 Multiservice Switch offers service providers the greatest level of choice and control over extensions of existing infrastructure and provides a seamless path to future services.

Product Overview

Based on the industry's most extensible architecture, the Cisco MGX 8950 Multiservice Switch (Figure 1) 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 is a patented system for supporting the industry's highest-density broadband interfaces for OC-3c/STM-1 and OC-12c/STM-4. 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.
