Across the board, service providers are redefining the value of their broadband pipes. To combat the commoditization of broadband, Cable, DSL and advanced mobile providers are moving into the realm of music, gaming, IPTV, VoIP, instant messaging and other multimedia services. To deliver this kind of content, service providers need more than a fast network. They need a smart network - a network that is application-aware, gives them a birds-eye view of bandwidth usage, plus the ability to control it and to guarantee service quality.

The same is true for enterprise, government, and education networks, which are becoming purveyors of broadband access and multimedia services in their own right. L7's technology and solutions are designed to provide this kind of visibility and control. The InstantQoS device and its management software gives service providers the ability to leverage pipe ownership without costly upgrades, and to ensure that IP services work the way you want them to¡Xefficiently, reliably, and profitably.

Step 1. Visibility:
      Discoverying & Monitoring the Applications

Do you know what your subscribers are doing online?
The often-heard advice to "know your network" is needed by broadband and WAN operators more than ever before. Being able to identify the applications and users on the network, and to quantify and analyze the traffic they generate is an essential first step to capacity planning, to subscriber demographics and service optimization. Without granular visibility into network traffic, you are simply working blind.
How many of your subscribers are using "free" VoIP applications like Skype
How many XBox Live subscribers are on your network
How much bandwidth each of the peer-to-peer file sharing protocols is consuming
Which subscribers are your "top-talkers" consuming the most bandwidth, and at what times of day
How much bandwidth email, HTML, news groups and streaming radio/video consumes

Placed at critical junctures in the network, InstantQoS devices use advanced deep packet inspection (DPI) technology to enable real-time monitoring, collection and processing of data directly from the network's traffic flows. At wire speed, InstantQoS inspects data packets at Layers 3-7, and classifies the traffic. The granular usage statistics gathered by InstantQoS throughout the network are transformed into a complete array of meaningful "network intelligence" by L7's central network management system. Tens of real-time, interactive graphs, charts, and reports show who's doing what on the network - right now and over time - giving service providers the tools they need to drill down into individual traffic flows and to control service delivery according to service level agreements. Long-term reports highlight usage trends and take the guesswork out of future capacity and service planning. Moreover, InstantQoS helps you to identify applications on a per-subscriber basis, providing the insight you need and the tools required to roll out new application-specific service levels that maximize ROI on infrastructure investments, reduce customer churn and increase revenue per customer.





Step 2. Control:
      Shaping & Guarantee the Traffic

      In fact, recent L7's studies have confirmed that it now takes almost 20% of top users to account for less than 80% of this Internet traffic. File-sharing will continue to consume bandwidth and stress both the access network and Internet transit links. L7 Networks understands that service control and fair access are not mutually exclusive terms. Proactive steps are needed to control these immense cost pressures that remain significant despite the slow downward trend of wholesale bandwidth prices. With much broader subscriber usage, however, service providers must consider intelligent approaches for P2P traffic management that preserve their subscribers' online experience while delivering the necessary bandwidth savings.
Bandwidth Control
With L7's InstantQoS in the network, carriers and operators are able to identify hundreds of applications and protocols, as well as user profiles, and to dynamically shape broadband traffic according to preset QoS policies.
External Link - Protecting the Mission-Critical Traffic: L7 Network's Layer-7 deep packet inspection and classification technology differentiates between the different flavors of VoIP, P2P, streaming video, web browsing, and a host of other protocols. This makes it possible for service providers to prioritize and control the delivery of individual services - both for applications that don't know how to request a particular QoS from the network, as well as those that ask for more bandwidth than can be allocated at a given moment.
External Link - Shaping the Bulk-Transfer P2P: No matter how much bandwidth service providers make available, the increasing popularity of peer-to-peer file sharing and the growing size of the uploaded/downloaded files will cause congestion on the network. Infrastructure upgrades provide only temporary relief, while their cost cuts into operator margins. InstantQoS' dynamic traffic shaping through QoS policies can be applied specifically to P2P traffic flows or P2P users, putting the network operator in complete control of how bandwidth resources are allocated. This is the key to preventing P2P congestion, reducing costs, and ensuring a quality experience for every customer.
Internal Link - Sorting the Up/Down Ranking: With L7's InstantQoS in the network, carriers and operators are able to identify hundreds of applications and protocols, as well as user profiles, and to dynamically shape broadband traffic according to preset QoS policies. L7 Network's Layer-7 deep packet inspection and classification technology differentiates between the different flavors of VoIP, P2P, streaming video, web browsing, and a host of other protocols. This makes it possible for service providers to prioritize and control the delivery of individual services - both for applications that don't know how to request a particular QoS from the network, as well as those that ask for more bandwidth than can be allocated at a given moment.

Step 3. Protection:
      Mitigating & Identifying the Threats

      The Internet is under constant attack. And many residential broadband subscribers remain completely vulnerable as they understand neither the dangers nor the relatively simple steps to avoid even well known exposures. So a service provider's own subscribers have become a major source of malicious traffic that degrades service not only for the infected subscriber but for surrounding subscribers on the shared network. As a result, service providers have been forced to bear escalating support call costs along with a higher risk of customer churn resulting from frustrations due to poor service quality.
Multi-Stage Optimization Process
1st-Stage: Mitigating the Overloaded Traffic: The Internet is a network of always-on, equally-connected, easily-reachable peers. That is one of its greatest benefits. It also is one of its greatest challenges. Numerous applications on the Internet incorporate the host's IP address in the application-layer data, providing a vehicle for the propagation of SPAM, viruses and worms that are designed to overload the network and to cause denial-of-service (DoS) storms. Likewise, current routing technology enables large numbers of hosts to share a single unique IPv4 address, making individual culprits difficult to identify and control. Mitigating these and other security threats is essential to protecting the network from attacks that harm service delivery, performance, and profitability.
2nd-Stage: Identifying the Criminals: InstantQoS devices equipped with the central management system give service providers the power to identify suspect traffic in real-time and to automatically isolate and neutralize it before it affects service performance. Placed at critical junctures in the network, L7's solutions create an application-aware layer of security control with configurable inspection, notification, and enforcement policies.
Complete Security Solution
      L7's Security Alliance solution is a managed security service that protects subscriber services against unpredictable attacks. This managed service approach enables service providers to fully benefit from our experienced security professionals who analyze potential threats from major service provider networks around the world.
Professional IPS with InstantLock: This solution leverages the same strengths of DPI signature analysis and behavioral analysis that isolate evasive file-sharing traffic. Known attacks may be identified using both signature and behavioral thresholds. Unknown attacks also referred to as zero-day attacks, can be immediately identified by preventive behavioral thresholds that are always active across the network. This capability is critical as new attacks are most damaging in the early hours when most networks lack protection using identification signatures. InstantLock's complete IPS solution provides the protection exactly when you need it - always - so potentially damaging attacks won't affect your subscribers or generate Support Center calls.
Centralized Reports with InstantConfig: The central network management and reporting tool provides granular visibility into what is really happening on your network. Both summary and detailed malicious bandwidth reports are available for all types of attacks including worms, DoS and spam Trojans. And by setting up customized alerts, your network operations team will be notified about any unexpected attacks or malicious activity needing immediate attention.





Step 4. Differentiation:
      Prioritizing the Services

      With the growing popularity of multimedia applications, it has become evident that today's best-effort networks are not well suited to provide consistent, high-quality services that subscribers expect. Applications such as online gaming, VoIP telephony, video telephone, IPTV and others are easily affected by unpredictable jitter and latency that are characteristic of today's network infrastructure. Additional bandwidth to solve this problem is not feasible by itself - continually adding new capacity is not cost-effective and simply does not resolve the underlying congestion issues that can unpredictably appear, particularly in the access network.
Differentiate subscribers with new application-based services
Service providers today have an early opportunity to offer subscribers a higher quality experience for multimedia services by introducing new QoS-prioritized services. The number of subscribers actively using multimedia applications around the world is increasing at a dramatic pace although bandwidth consumed remains relatively low in stark contrast to file-sharing applications. Experience to date is confirming that these subscribers place a high value on a consistent, quality experience that exceed typical best-effort services even for higher bandwidth offerings. Fortunately application-based QoS can be easily introduced in combination with existing bandwidth-based service tiers to target specific market segments.
Ensure the quality of VoIP on your network
VoIP has become a leading candidate for differentiated services given the urgent need to secure new digital voice customers. Service providers can immediately develop a more effective VoIP business strategy using InstantQoS' reporting to better understand VoIP activity by their subscriber base. The next step is to introduce QoS for voice services in order to avoid the unpredictable service impact of bandwidth-consuming file-sharing applications.
Ensure the quality of online gaming on your network
Online gaming is another key service opportunity with the expanding popularity of Xbox Live, Playstation and PC-based games. Again, service providers can quickly understand gaming activity across their subscriber base, using InstantQoS' reporting, to plan more effective services and marketing campaigns. InstantQoS identifies a broad range of games so service providers can feel confident knowing which games are most popular with and ensuring that those games receive proper QoS levels.
Target: Pricing for the revenue
Tiered pricing, quota-based services, and pay-as-you-go plans are just some of the options being explored and adopted by broadband service providers to satisfy different market segments and to increase ARPU. Differentiated services depend on the operator's ability to identify individual subscribers, applications, and service plans, to track their usage of the network, and to guarantee the performance promised in service level agreements.
Currently, "best-effort" networks have no way to guarantee the minimum bandwidth and priority needed by premium services such as delay-sensitive VoIP or interactive gaming applications. With L7 InstantQoS in the network, operators can block, limit, prioritize, or guarantee bandwidth per application, per subscriber, and per service package. Even during peak usage periods, InstantQoS maintains optimal service levels by intelligently controlling the available bandwidth and number of connections that each application and user gets. L7 Networks' DPI-based solutions turn simple connectivity networks into "application-aware" networks that can support service tiering and SLA enforcement.





Step 5. Operation:
      Cost Optimization & Usage Billing

      Service providers are always on the lookout for ways to increase ARPU. The concept of charging for multiple data services customized to individual needs has broadband service providers discussing new pricing models that bundle basic Internet access with multimedia content services into a variety of consumer packages. An integral part of this discussion is how service providers will guarantee the quality of delay-sensitive applications like streaming video or VoIP. How will they track usage and charge for specific content and applications, or for premium delivery? And how will they offer all these services to prepaid users, who require real-time charging?
      L7's broadband management technology enables DSL, cable and mobile operators to overcome these hurdles and capitalize on these new revenue opportunities. L7's unsurpassed DPI, service awareness and QoS management capabilities make it possible for carriers to bill individual subscribers for specific content or application usage in addition to volume or time of connection. InstantQoS' solutions also support the complex business models involved in providing IP content and services, by addressing the need for a centralized way of charging and the need to share revenues with different parties in the delivery chain.
