Traffic classification Understanding the types of applications and services, as well as the protocols being used in the network, is key to determining how to manage subscribers’ bandwidth consumption for optimal network performance. It’s also key to developing and monetizing innovative services while ensuring optimal network efficiency and utilization monitoring.
For example, as your subscriber is watching a TV show on YouTube, you can prompt the subscriber to purchase a “turbo button” feature which, when activated, delivers a burst of bandwidth to the subscriber’s device. The result is a better experience for the subscriber, and incremental revenue for you. BIG-IP PEM gives you the ability to classify traffic into several categories of applications and protocols—including classification of application subcategories that include voice, video, and IM. These are some examples of the types of apps and protocols BIG-IP PEM supports:
- P2P: BitTorrent, Gnutella
- VoIP: SIP, Skype, Yahoo!, Jabber
- Web: HTTP, HTTPS, FTP, YouTube, Facebook
- Streaming: HTTP streaming, RTSP, HTTP audio
- Non-TCP/UDP: IPsec, GRE, IPinIP, ICMP
As the number of apps and services being used in the network grows, you need to continually update your signature libraries to ensure that protocol classifications and subscriber plans are accurate, based on subscribers’ usage patterns.
To this end, BIG-IP PEM(BIG-IP Policy Enforcement Manager (PEM) License) supports dynamic and hitless signature upgrades, so you can seamlessly receive new signatures for new or existing applications—without having to perform a software release upgrade. Other types of traffic classification employed on BIG-IP PEM include behavior and heuristics analysis, and deep packet inspection
Subscriber awareness BIG-IP PEM performs subscriber discovery via RADIUS and/or DHCP and provides information such as IP address, IMSI, and user name, which, when correlated with application flows, allows for deeper understanding of the type of applications and services subscribers are using and how they are using them.
In addition, BIG-IP PEM can retrieve info on RAT type (Radio Access Technology) via RADIUS messages and can apply different policies based on subscriber use of 3G or 4G LTE networks. BIG-IP PEM can also function as a RADIUS client for authentication and accounting for subscribers.
Video traffic is a major source of congestion in a service provider’s network—causing significant degradation in subscriber QoE if not managed carefully. With the BIG-IP PEM video analytics capability, service providers can get enhanced visibility into media traffic including reporting on video type, encoding rate, resolution, and video mean opinion score (MOS).
Leveraging this information, service providers can apply specific policies based on video type per subscriber. For example, premium subscribers will be able to stream HD video, while non-premium subscribers will only be able to stream SD video for that specific application (while streaming HD video for all other applications).
RAN congestion detection and control
Data-intensive applications (including mobile video) continue to place significant strain on service provider networks, and more specifically on resource constraint elements such as the Radio Access Network (RAN). As one of the most expensive elements within service provider networks, the RAN must be optimized and policies implemented to detect and control congestion within the RAN.
This enables service providers to optimize network resources while improving subscriber QoE. As an inline network device, BIG-IP PEM monitors subscriber throughput, loss rate, and delay. It can then apply specific policies to the subscriber traffic, including rate limiting and steering specific subscriber traffic to optimization services—leading to reduction in traffic congestion. As a result, the service provider can save CapEx and OpEx on core network infrastructure and provide a high QoE
Mobile subscribers, on average, are expected to have 3–4 devices with them at any one time. However, many do not have separate data plans for each of their devices, instead tethering their devices to their primary device, typically via WiFi. From a service provider perspective, unauthorized tethering of devices leads to additional bandwidth strain on their already resource-constrained network, leading to poorer quality of experience and loss of revenues.
Service providers need to be able to detect tethered devices and apply policies to reduce the impact on their network. BIG-IP PEM supports a comprehensive set of tethering detection algorithms. These polices allow service providers to alleviate network congestion and increase revenue streams with new plans for subscribers.
BIG-IP PEM includes a highly optimized TCP/IP stack that provides leading edge TCP/IP techniques (which minimize the effects of congestion and packet loss for 3G/4G networks). TCP optimization delivers up to 2x performance gains for subscribers and a 4x improvement in bandwidth efficiency.
HTTP header enrichment
HTTP header enrichment enables you to append the HTTP header with information such as MSISDN, IMSI, and IP address, which can be used to provide further subscriber awareness to the application or service. With this capability, BIG-IP PEM (located between the subscriber’s mobile device and the network) enables you to provide a more personalized and interactive experience—all while increasing ARPU.
