Using the NLR for WAN Backbone Bandwidth

Cisco supports more than 60 percent of its global employee population in the United States, and Cisco network traffic is growing on the North American backbone WAN at a faster rate than anywhere else in the world.  Cisco’s North American backbone connects the company’s San Jose, California, headquarters with other large Cisco locations, including Richardson, Texas (our new primary production data center), and Raleigh, North Carolina (a key development location and our primary data center disaster recovery site).  In addition, there are seven other locations on the North American backbone that serve as WAN aggregation hubs for more than 120 regional WAN sites, as well as interconnects to backbone locations in Europe, Asia, and South America. 


The WAN backbone in North America has grown from three hub locations connected via DS3 (45 Mbps) in 1999 to 10 locations connected via OC-48 (2.488 Gbps) in 2007. In 2009, The Cisco OC-48 backbone was stressed by both ongoing data center migrations (thousands of applications and petabytes of data) and rapidly increasing voice and video traffic.  Utilization on several individual backbone circuits routinely reached 80 percent or higher.  High utilization created periodic performance issues and put the business at risk of significant impact should a backbone circuit fail during peak traffic hours.
