… And the Network

Mobile app downloads are skyrocketing. It took the Apple App Store just 2.2 years to reach 6 billion downloads; it took Apple’s iTunes five years to reach that milestone. Of course, many of those apps are free.
Netflix’s streaming traffic is growing. According to statistics from deep packet inspection (DPI) vendor Sandvine, streaming video content provider Netflix now accounts for 20.61 percent of downstream traffic in North America during peak hours, second in traffic volume only to generic HTTP sessions.
Smartphones sales are outstripping PC sales. Yankee Group forecasts that sales of smartphones will reach 475 million units in 2012, exceeding the sales of PC and notebook computers combined for the first time. Apple’s iPad continues to sell like crazy. Apple released the iPad in Q2 2010 and sold 3 million of the tablet computers in 80 days. By the end of 2010, the company had sold over 14.8 million iPads.
Apple is targeting sales of 100 million iPhones in 2011. That’s double what they sold in 2010 (47.5 million), which was double what they sold in 2009 (25 million), which was double what they sold in 2008 (13.8 million)

DNS: The Force That Surrounds Us
Is used to connect to every Web site and every e‐mail address box
• Allows us to turn this: 206.19.46.107
into this: yankeegroup.com
• Works so well that we forget about it (until it breaks)

Ask Your ISP

Pros
• Has the potential to resolve almost all the vulnerabilities of in‐
house managed DNS
•
Cons
• It rarely does
•
DNS management is not the main function of an ISP. As a result, DNS performance is likely to suffer in terms of: •

•
Bandwidth
Latency
Support

Anycast vs Unicast DNS Routing
• Unicast (one-to-one)
• Communication between a
single client and a single server
• Anycast (one-to-one-of-many)
• Communication between a
single client and the topologically
closest instance of a network
service that is represented in
multiple places by a common IP
address
27
Verisign’s Hybrid (Anycast + Unicast) Routing
Approach
• Anycast only resolution approach implies a tradeoff
between performance and availability
• Better served by a hybrid solution
• A smaller number of name servers within a zone is Anycasted,
while the remaining servers are Unicasted
• Minimizes transactional latency while optimizing
availability
• Provides customer with ability to determine their
tolerance between performance and availability
• Verisign has used this approach to manage DNS
resolution for .com and .net
