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

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 CAPNet Growth

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

Results—Cisco 7600 Series Is Backbone of Global WAN
• Ten pairs of Cisco® 7600 Series routers now in global WAN backbone:
Seven pairs in the United States
Three pairs in Europe
• Performance and availability have been excellent
In 2002, Global WAN links had 99.99% availability
In 2003, Global WAN links had 99.999% availability in some quarters

Next Steps—Cisco 7600 Series Supports New Technologies
• WAN migrated to MPLS VPN in EMEA
Cisco® 7600 Series routers deployed in Amsterdam, London, and Brussels to handle STM-4 and STM-1 circuits into MPLS provider network
• QoS supported on the WAN
Voice, video, control, normal, and batch data traffic
Cisco 7600 Series handling QoS (CBWFQ) traffic marked at edge
• Source Specific Multicast and IGMPv3 support added to Cisco 7600 Series (and other routers) in WAN
Simplified multicast architecture adds to stability
• Each feature supported in Cisco IOS® Software, required no hardware upgrade
