Presentation_ID Overview Challenge—WAN Growth Traffic growth, new applications drove Cisco® to higher WAN speeds Solution—Cisco 7600 Series Router for high-speed WAN Cisco 7600 Series supports OC-12, STM-4, with good features, performance, migration path Results—Cisco 7600 Series now backbone of global WAN 10 pairs of Cisco 7600 Series routers deployed globally WAN availability at all-time high in 2003 (99.999%) Next Steps—Cisco 7600 Series supports new WAN technologies MPLS VPN, QoS, SSM support added easily

333 © 2003 Cisco Systems, Inc. All rights reserved. Presentation_ID Challenge—WAN Growth WAN utilization was growing rapidly Average total utilization across global WAN links doubling every 9 months OC-3 between San Jose and RTP nearing 50% utilization in 2002 New peer-to-peer applications being added IP telephony IP video E-working/collaboration tools Cisco® 7200 and 7500 series routers don’t handle above OC- 3, STM-1

444 © 2003 Cisco Systems, Inc. All rights reserved. Presentation_ID Solution—Cisco 7600 Router for OC-12 WAN New WAN design required OC-12 connectivity Underlying LAN platform is Cisco® Catalyst® 6500 Series switch and router Cisco 7600 Series Router is based on Catalyst 6500 Series technology, with support for higher speeds and higher OC-x and STM-x port connections Cisco 7600 Series supported all required interfaces, with a small footprint, a reliable track record, and a good migration plan Cisco IT selected the Cisco 7600 Series Router to support the backbone of our global OC-12 / STM-3 / OC-3 / STM-1 WAN for 2003
