ALU 9900 Detector

ALU 9900 Central

By connecting individual subscribers to resource consump- tion, the Alcatel-Lucent 9900 helps service providers manage the effects IP-based applications have on wireless networks. IP applications in use today were not designed with wireless data network constraints in mind, and as

a result, can easily and unexpectedly burden the radio access network. In fact, subtle changes in the transmission characteristics of wireless data sessions can have a profound impact on network performance.

With the Alcatel-Lucent 9900, service providers can ensure they make the best possible use of their network and the precious air spectrum between the network and the mobile endpoints.

How It Works

The Alcatel-Lucent 9900 is built with two components: a detector and a central.

The detector monitors data and radius traffic that is mirrored from within the packet core of a 3G/4G network. It generates “events” based on observed behaviors. It also generates a new flow record, which is a wireless-specific net-flow record, which is a subscriber-specific net-flow record, appended with context specific to wireless data networks. The deployed detectors securely communicate this information to the central, which provides GUI- access to the detectors, reports, forensics, and control.

Value

This information is proving inva luable for wireles s serv ice provi ders on many levels:

•Operations — It allows service providers to determine which subscribers, servers, and applications are the most significant contributors of non-value-add traffic and load on the network.

•Planning — It enables service providers to establish a baseline measurement of network use at the individual subscriber level, allowing more accurate predictions of network capacity trends.

•Engineering — It ensures packet transmissions from devices and networks are consistent with design, and are not being sent fraudulently.

•Security — It allows service providers to detect a new class of wireless-specific denial of service attacks targeted at the signaling layer and exhausting RF chan- nels, as well as the mobile devices that are directly

or surreptitiously participating in the attacks.

•Marketing — It helps service providers determine the network cost associated with supporting any given application, thereby enabling application-level ROI
