Consumption-Based Billing Coming?

Sandvine has released Usage Management 2.5, a software solution that enables fixed-line network operators to implement consumption-based billing models, real-time subscriber communications and multiple service plan tiers. The move is significant as it suggests retail pricing might move in that direction in the future, representing a major shift in retail pricing models.

Historically, consumption-based billing has been problematic for Internet service providers. Time Warner Cable tested and then decided not to implement metered billing earlier in 2009 after widespread consumer resistance to tests in in Rochester, N.Y., Austin and San Antonio, Tex., and Greensboro, N.C.

User behavior also is powerfully affected by billing methods. At one point in time America Online charged users by the minute for their dial-up Internet access usage. When it converted to flat fee billing, usage and subscribers exploded, and AOL became the largest U.S. ISP.

Similar results have been seen when other types of services, such as voice calls, also moved from per-minute to flat rate or "buckets" of usage. Generally, users spend more time talking or using the Internet when they are not metered for that usage.

Mobile voice services have a half-way approach that combines usage limits with much of the perceived freedom users feel when they are not charged strict per-minute charges. Such "buckets" of usage are a likely direction much retail Internet access pricing will move as bandwidth-intensive applications become more important and if new "network neutrality" rules forbid ISPs from shaping overall demand at times of peak congestion.

The alternative to traffic shaping then would shift to other measures such as increasing raw bandwidth or providing incentives for users to limit their consumption at peak hours. The former obviously requires more investment, which then would have to be reflected in higher prices, while the latter would allow for more gradual investments and therefore stable or more slowly increasing prices.

One problem today is that few consumers have any idea how much bandwidth they use. The new Sandvine tool would simultaneously allow users to monitor and understand their own behavior, as well as provide ISPs with better ways to create plans matched to end user behavior.

The Sandvine tool also would help ISPs create quality-sensitive service or personalized plans, assuming Federal Communications Commission or Congressional rules allow them to be offered.
