Bridging the Gap Between Legacy and Next Gen Apps
By Erik Linask, Group Managing Editor
The predominant thinking today is that while network hardware is necessary, the revenue potential lies in the applications and providers’ capacity for enriching the end user experience. Of course, that means ensuring both ease of use and applications availability. The problem is that traditional application delivery models are ill equipped for an application-centric network environment that features as many access networks and devices as it does applications — or more.
Fortunately, companies like AppTrigger recognize the need for service providers to be able to roll out multiple applications across multiple access networks quickly and cost effectively — and they must be able to ensure and control access to those applications.
So, the question becomes, how quickly can a solution designed to drive application layer control turn into a revenue producing component for service providers. AppTrigger has purpose-built its Application Session Controller as a highly scalable solution designed to increase service providers’ and application developers’ ability to bring products to market by limiting the amount of rewriting and reconnecting in order to extend services across multiple networks. AppTrigger estimates something in the area of 40% savings can be achieved compared to traditional application deployment models.
AppTrigger’s Ignite ASC (News - Alert) resides at the application layer, between the application layer and the core network, controlling application connections in today’s next generation network environments. Its programmable network abstraction engine insulates the application server farm from the network, providing the application specific call-control functions, independent of network.
Even setting aside the current fiscal environment, the costs associated with application rewriting in large-scale deployments exceeds $10 million per application. That’s a nearly insurmountable expense to have to recover, especially when factoring in the end user’s need to limit expenditures as well, and service providers struggle to find ways to leverage existing applications and retain associated client bases and revenue streams.
For example, replacing non-IMS applications as part of a move to an all-IP infrastructure if counterintuitive is the providers can’t generate new revenue from the application. On the other hand, IMS networks do not easily allow legacy applications access to IMS elements. This combination has delayed a number of IMS network deployments while service providers build business cases for moving forward. This, in turn, is detrimental to the growth of not only the providers, but the application developers and network equipment manufacturers as well.
In an environment where voice services are seeing declining revenues, service providers will have an increasing impetus for bridging the gap with other multimedia and Voice 2.0 services and applications. And they will need to be able to roll them out quickly and efficiently. Enter the ASC.
ASCs will give service providers a reliable, cost-effective, network agnostic platform that will enable the rapid development and deployment of a new generation of multimedia applications. Importantly, they will not disassociate legacy applications. Instead they will create a service and application delivery mechanism that blends the old and the new — just as end users are still using the old and the new.
So, as this new paradigm of application delivery continues to evolve, the most effective means for service providers to increase revenue streams is to deploy application session controllers, which have been specifically designed for just this multi-generation technology environment.
