When Does WebRTC Need a Media Server? Reason #6

July 15, 2014

In a recent blog about the current state of WebRTC, I mentioned that readers should check out an excellent white paper about seven situations in which WebRTC would need server-side media processing. Written by Tsahi Levent-Levi, a leading blogger at BlogGeek.me and WebRTC activist, the white paper gives a great overview and unique point of view about why media servers matter.

In the next few weeks, I will explore some of the seven reasons from Tsahi’s white paper. Today we’ll dive into reason number six: processing of the media stream.

The Top Five Tips for Transforming Your Legacy Switching Environment

July 8, 2014

Softswitches, once bastions of the “new” IP telecommunications environment, are now regarded as legacy equipment in some circles. Replacements to full IP multimedia system (IMS) environments are still in full swing, but that takes capital and operational expenditures (CAPEX and OPEX). Upgrading your old softswitch to a modern one can be a better way to go for many carriers. Why?

NFV and SDN: Diameter Signaling Controllers Join the Best of Both Worlds

July 1, 2014

 

In the Heavy Reading white paper, “Control Plane Orchestration: The Evolution of Service Innovation Attributes,” analyst Jim Hodges writes that the telecom industry has never before simultaneously experienced two foundational disruptive technology trends that are complementary. What is he talking about?

TADHack: Adding the Human Element to Communications

June 24, 2014

A few weeks ago, I attended a new developer show in Madrid called TADHack. It’s a smaller event and very different from the average conference. As soon as I walked into the venue, I noticed this weird green hue, kind of like I was in the Wizard of Oz. It had the feel of a nightclub, which was fitting since the developers were hacking late into the night.

TADHack is geared toward communications and voice developers, particularly over-the-top (OTT) communications app developers.

Wi-Fi Offload/Roaming Part 3: Diameter and LTE Interworking Is Crucial

June 17, 2014

In my last blog, I discussed the architectures needed to roam between Wi-Fi and 3G/4G networks. In order to enable interoperability between the different architectures, a mediation and interworking platform is required to support the different scenarios in which RADIUS, Diameter and SS7 are used.

RADIUS is critical for interworking with Wi-Fi networks. Authentication and authorization of roaming subscribers is performed through RADIUS messages over an inter-operator interface between the visited network provider and home service provider.

Is WebRTC for Real or Not?

June 10, 2014

57 percent of respondents to our WebRTC Impact Survey have WebRTC solutions already in development.

Next week, Dialogic will head to Atlanta for the WebRTC Conference & Expo.  While there are many WebRTC-focused events out there offering demos and expert advice, I consider this one to be the best.  So as we prepare for this year’s Expo, now is a good time to ask: Is WebRTC for real? 

Wi-Fi, 3G/4G Roaming and Interworking Architectures

June 3, 2014

In a recent blog, I discussed Wi-Fi roaming and the wireless roaming intermediary exchange (WRIX), which is similar to an internetwork packet exchange (IPX) for Wi-Fi roaming. The WRIX is broken down into three levels that cover the various interactions needed between operators to support roaming.

The first level, WRIX-i (interconnect), specifies the interface between the visited network provider (VNP) and the home service provider (HSP). WRIX-i requires the use of RADIUS authentication, authorization and accounting (AAA) procedures and some specific attributes associated with access and accounting services.

OTT is / is not a threat to interconnect carriers

May 27, 2014

Two weeks ago, I traveled to Chicago to attend International Telecoms Week (ITW), the annual meeting for the wholesale telecommunications community. One morning, I was reading the show news daily and sipping my morning coffee when I came across an interesting article. It was about whether the wholesale market thinks over-the-top (OTT) technology is a threat or an opportunity. The article cited a Capacity Magazine survey that showed 82 percent of the wholesale market leaders surveyed see OTT as an opportunity.

LTE Is Not the Answer - But WiFi Might Be

May 20, 2014

Right now, LTE is in its heyday. Carriers are doing all they can to expand coverage and improve speeds, and those lucky enough to be using it probably experience great service. But as mobile data use increases, that honeymoon period will end as networks get clogged and overloaded.

As that happens, WiFi networks will become an increasingly important way for carriers to improve coverage and capacity.
