In my last blog, I talked about the effects that convergence may have on the future. This week, I’d like to address the factors that need to be considered when it comes to user experience convergence. First of all, the delivery network needs to be context-aware. For example, what is the type of end-point being used (since you don’t want to send 720P to a CIF device)? The delivery network will also need to make the frame size, screen size, codec and transport adjustments depending on the video source. Subscriber awareness is also important to consider since the subscriber may be paying for differentiated services of some sort. The network also needs to be content-aware – what is the type of video, how good is the source of the video? And finally, the delivery network needs to be network aware – what is the available bandwidth and what is the quality of service. Additionally, including analytics to see the video usage pattern can help in delivering the best quality of experience.
Finally, putting this all together, what does cloud and user experience convergence mean? Well, for one thing, it means your device doesn’t define you. And it means that we may be moving to thin-clients – if you will be utilizing a wide range of devices, and the network will be “personalized” for you, then all your information will need to be stored in the cloud.
So where does Dialogic fit in, you ask?
As I’ve discussed over the course of the last 3 weeks, mobile networks are delivering entertainment and information to an ever-widening world eager to connect quickly and seamlessly. Dialogic focuses on the promise of this technology. In fact, today, networks using Dialogic technology carry more than fifteen billion minutes of traffic per month, and services built on Dialogic products are used by an estimated two billion mobile subscribers worldwide.
Here’s how Dialogic plays a role in the convergence challenges of today and those that lie ahead:
- Dialogic offers voice and video media gateways, session border controllers and softswitches, all of which enable the networks to co-exist and interoperate with each other.
- Dialogic’s media server, media gateway and signaling server technology enables our worldwide customer base to create innovative and revenue-producing value-added service applications that they sell to service providers. Increasingly, these services are becoming video-enabled so our media server, signaling, and gateway product lines incorporate the video technology required to build a video mobile service on Dialogic products.
- Dialogic also has both core network and backhaul network optimization technologies and products that enable the most capacity to reside on given bandwidth. Customer testimonials indicate a 50% bandwidth savings with backhaul network traffic.
- Dialogic is also playing a key role in video quality of experience. Dialogic Media Labs, with a mission to focus on R&D related to mobile video, has created technologies that allow measurement and comparison of the video stream at the source and at the device, so that quality of experience can be known and potentially appropriate actions taken in the network.
I hope you’ve learned a lot about communications convergence from my last few blog entries.
