96 | BROADBAND COMMUNITIES | | MAY/JUNE 2015 TECHNOLOGY IPDR: More Than Just Usage-based Billing The Internet Protocol Detail Record provides a wealth of data that operators can use for planning, engineering, sales and marketing. By Francisco Viana / Incognito Software Systems W hen engineers think of Internet Protocol Detail Record (IPDR), the frst thing that comes to mind is usually usage-based billing. Although usage-based billing is the reason the cable industry frst adopted IPDR, the information this protocol provides goes way beyond billing and has similar benefts for telephone providers, fber-to-the-home operators and other broadband industry players. In recent years, cable modem termination system (CMTS) vendors have expanded their support of IPDR to provide access to more network and subscriber usage information. Tis data can be used for managing congestion, planning investments and even for marketing. Tis information is automatically sent from a CMTS without slowing down a network or violating user privacy because it provides a summary of subscriber usage without getting into what application and service subscribers use. NEW USES FOR IPDR Cross-referencing IPDR data to subscriber MAC addresses and adding geolocation, subscriber plan information and account types produces a complete dataset that can not only serve engineering purposes but also assist marketing, product, planning, sales and every other department of a service provider. IPDR allows the collection of data from a CMTS in streams. A provider can pinpoint – with high accuracy – the utilization of every cable modem on its network and can identify which interface, node and service group this trafc comes from and how much bandwidth each interface utilized, establish the maximum throughput and discover possible congestion points in the interfaces, nodes and service groups. Every department of a modern operator – from engineering and planning to marketing and sales – can use this data. On the engineering and planning side: • Understand where network congestion occurs. Gain visibility through notifcations and key performance indicators of congestion points and trafc patterns that can lead to congestion. • Predict congestion points to make smarter investments. Analyze past subscriber growth and subscriber bandwidth utilization trends to predict saturation of interfaces and nodes. Tis allows operators IPDR data can help operators make strategic investments in their networks to relieve congestion most efectively at the lowest cost.
