===Tiered services===
Mobile and broadband service providers use DPI as a means to implement tiered service plans, to differentiate "[[walled garden (technology)|walled garden]]" services from "value added", "all-you-can-eat" and "one-size-fits-all" data services.<ref>{{cite web|url=http://news.moneycentral.msn.com/ticker/article.aspx?Feed=PR&Date=20080205&ID=8139811&Symbol=ALLT|title=Allot Deploys DPI Solution at Two Tier 1 Mobile Operators to Deliver Value- Added and Tiered Service Packages|website=news.moneycentral.[[MSN]].com|date=2008-02-05|access-date=2008-03-03}}{{dead link|date=November 2016|bot=InternetArchiveBot|fix-attempted=yes}}</ref> By being able to charge for a "walled garden", per application, per service, or "all-you-can-eat" rather than a "one-size-fits-all" package, the operator can tailor their offerings to the individual subscriber and increase their [[average revenue per user]] (ARPU). A policy is created per user or user group, and the DPI system in turn enforces that policy, allowing the user access to different services and applications.
