It might seem like the telecom industry has been chasing the goal of application-aware networking for years on end, but the reality at the carrier level is that the migration to an AAN model is far from complete.
The recent Heavy Reading Insider report Application-Aware Networking: The Carrier Perspective (subscription required) gives a different sort of glimpse at a networking philosophy birthed by concerns about the ongoing data explosion, rapidly increasing network complexity, and the ability of service providers to cut through all that to enhance customer experience management.
AAN and the related, parallel trend toward application performance management (APM) have generated some industry debate. They have been touchstones this year for many vendor announcements targeting different zones of the network. These include the traditional hardware sellers (Cisco Systems' Application-Centric Infrastructure strategy) and the software-defined networking upstarts (Big Switch's application-aware Unified P+V SDN switching fabric). APM has inspired a rush among network monitoring vendors not only to get more granular with their monitoring capabilities, but also to ensure their systems can feed network and application data into big data analytics engines (See What Applications Will Want from SDN, Cisco's ACI Gets Physical With SDN, Big Switch Previews App-Aware SDN Cloud Fabric, and Gigamon Steps Up Traffic Intelligence.)
However, Steve Koppman, the report's author, found that some major carriers, including AT&T, were hesitant to discuss their progress on the AAN front. Also, it seems that carriers in general are just now adjusting to the notion that they can't improve application delivery and performance management simply through bandwidth upgrades.
"Until recently, market participants typically believed they could, and needed to, achieve acceptable application performance levels with resources near at hand," Koppman wrote. "New challenges were most often met by adding bandwidth or devices, with no requirement for anything like application-aware networking."
As carriers better understand the need for AAN and the options for making it happen, this long-discussed philosophy will finally come to fruition and bring its promised changes to the networking realm. Koppman sees that happening in another 3-5 years, which (coincidentally or not) is the about same timing as the anticipated software and virtualization revolution.

You want Dans? We got 'em! This one, "Fancy" Dan O'Shea, has been covering the telecom industry for 20 years, writing about virtually every technology segment and winning several ASBPE awards in the process. He previously served as editor-in-chief of Telephony magazine, and was the founding editor of FierceTelecom. Grrrr! Most recently, this sleep-deprived father of two young children has been a Chicago-based freelance writer, and continues to pontificate on non-telecom topics such as fantasy sports, craft beer, baseball and other subjects that pay very little but go down well at parties. In his spare time he claims to be reading Ulysses (yeah, right), owns fantasy sports teams that almost never win, and indulges in some fieldwork with those craft beers. So basically, it's time to boost those bar budgets, folks!
