The Need for Speed
10 Gigabit Ethernet (GE) rapidly became the technology of choice for high speed connections to servers and network devices. Advancements in Ethernet lossless switching accelerated the convergence of transport and storage area networks, and reduced complexity and cost. The need to deliver more business applications to more users continues to drive the adoption of higher speed Ethernet technologies such as 40 GE and 100 GE.
In most regions, users take broadband Internet access for granted. As a result, they spend more and more time online. Service providers must continually and reliably deliver higher speed and throughput to meet user expectations. Service providers annually spend billions of dollars building next generation application-aware IP networks in a bid to deliver exceptional performance. Their efforts have been largely successful -- according to Infonetics, North American voice, video, and data services revenue will reach $300B by 2013.
Consumers remaining continually connected impacts how mobile operators run their networks and do business. Many of the consumer services delivered over their networks -- video, music, social media, messaging, and hundreds of other applications that rely on Internet connectivity for real-time information -- are bandwidth heavy. Remaining competitive and profitable in this hyper-connected environment requires mobile operators to accelerate 3G/4G network deployments in order to meet the need for more bandwidth to more users.
Global Internet traffic is also increasing at a rapid pace. By 2010, estimates show that a mere twenty typical U.S. homes will generate the same network traffic levels as the entire 1995 Internet. A report by CIP Technologies
estimates that global traffic will double in two years, reaching a staggering 160 terabits per second -- higher than the total demand since 1998.

Network applications deliver services via sets of protocols, actions, and interactive behaviors. The advanced, content-aware devices included in such networks intelligently deliver these services end-to-end. Application aware devices detect not only the underlying network protocol, but also the content itself.
Unlike routing platforms that make decisions based on network addresses, application aware devices use a combination of application recognition and content analysis to make forwarding decisions. Such devices include:
•
Service load balancers (application delivery controllers) -- used as front-end servers that manage usersessions, accelerate and secure applications, and manage client-to-server interactions.
•
Firewalls – used as first-line defense in providing back-end services access to external and insecurenetworks, ensuring that only legitimate traffic is forwarded across networks.
•
VPN concentrators -- provides users connection to business services, as well as secure and seamlessinter-office connectivity between remote sites.
•
Intrusion prevention (IPS) – used to detect and neutralize thousands of application, network, and hostbased attacks by inspecting all packets inline.
•
Traffic management devices -- used to recognize network applications and shape various applicationsbased on business policies.
Network pipes that deliver gigabits per-second of speed are quickly becoming saturated with traffic generated from hyper-connected applications from the Internet, enterprise applications, and mobile network access. Today’s content-aware devices scale poorly when tasked with delivering applications quickly and reliably to end users. Network equipment manufacturers (NEMs) recognize the need for speed, and are bringing to market faster, more intelligent devices that are capable of scaling to the heights of next generation application delivery networks. Creating realistic application traffic (on the order of millions of user sessions, running at hundreds of gigabits per second) and reliably measuring key performance metrics of next generation, content-aware devices is a
significant challenge for NEMs.
Realistic Application Testing Challenges
Content aware devices using deep packet inspection (DPI) at the application and payload layer are an evolutionary step in managing user traffic. As a general rule, the more inspection that occurs, the more processing power is required to maintain performance levels. Full DPI device qualification requires a multi-dimensional testing scope.
Key testing challenges include:
•
Realistic emulation of application protocols, including transport protocols such as full TCP, UDP.•
Multiple protocol support with complete control of layer 7 configuration.•
Ultra-high number of user sessions, with millions of active users and IP addresses in use.•
Line-rate throughput performance, including exceptional small packet performance.•
Key performance metrics (KPI) for multi-dimensional tests at all performance level. Ixia’s application delivery testing solution meets these demanding requirements.Ixia’s 100G+ Application Delivery Solutions
