In testRTC, we have introduced a monitoring capability for WebRTC services - customers asked to be able to test their service instead of their servers :-) http://bit.ly/1H5mb9D
Monitoring WebRTC services wasn't easy. At least not until we've added it to our testRTC service.

I wonder how popular Websocket is going to be in the future, now that we have HTTP/2 out there: http://bit.ly/1SKEsQv
HTTP/2 is going to change the web. Part of it might end up changing signaling and messaging in browsers. Here's how HTTP/2 stacks up against WebSockets.

I was asked to write a few posts that are more basic about WebRTC. Here's one that I did due to a question I was recently asked: Why and how do browsers exchange their IP addresses in WebRTC - http://bit.ly/1IprLZW
To understand WebRTC basics, you need to understand how and why WebRTC is peer-to-peer and what the browser's IP address has to do with it.

The success of the H.265 video codec will be determined by the adoption (or non-adoption) of it by the browser vendors: http://bit.ly/1HLc9OZ
H.265 is upon us, but will it really gain market share with the current set of patents and unknown licensing scheme? Especially, when we shift into a word ruled by browser based WebRTC communications?

It seems like there's a lot of indication out there that Microsoft Edge might take the lead and be the best browser in town when it is finally released with Windows 10 later this month: http://bit.ly/1OtPY1Z
Microsoft Edge sure looks promising from recent announcements. How does it measure up to the rest of the browsers, and will it become the leader of the pack?

Plugins are dying. Flash is being scrutinized and blocked. What's holding you from using WebRTC? http://bit.ly/1HEfmjj
Now that both plugins and Flash have a murky future ahead of them in our browsers, it seems like a good time to start using WebRTC instead of complaining it isn't available everywhere...

Not our cup of tea. We don't do PESQ at the moment.

I don't see a way that HEVC patents can kill WebRTC. At worst (best?) they'll constrict the adoption of HEVC to limited, high-value, commercial applications.

WebAssembly & HTTP/2 are changing how we experience the world. Instead of receiving it verbose, we are now receiving it in a binary form: http://bit.ly/1O9jaLD
The web is shifting away from textual protocols to binary ones. Why is this taking place and how will it affect us all?

Introduction

My name is Tsahi Levent-Levi and I am an independent consultant. I also work part time as a Product Manager at Amdocs.

During the past decade I have worked at RADVISION, taking part in the development of various VoIP and 3G projects as a programmer, manager and marketer. This included developing the 3G-324M protocol stacks from scratch, as well as managing the team that was in charge of developing and maintaining the H.323 protocol stack. In addition to my work at RADVISION, I have an MSc in Computer Science and an MBA degree with a focus in Entrepreneurship and Strategy.  I have also been granted two patents related to 3G-324M call optimizations. Additionally, I act as the chairman of the IMTC IMS Activity Group, which focuses on interoperability issues relating to IMS client. I am also an active participant in other international organizations dealing with standardization and interoperability in the video conferencing industry such as the 3GPP, ITU and GCF. Currently I am taking part in developing an innovative video client project being developed by RADVISION.

I am blogging a lot about WebRTC, VoIP and my industry in numerous places.

When I am not working and blogging I enjoy playing with my two great kids, developing new culinary innovations in my suburban Tel Aviv kitchen, and practicing Argentinean Tango with my lovely wife.

I have started working with Xilium by a referral from a friend half a year ago, and have been moving more and more of my HTML and Wordpress work needs to them. The Xilium team is great. They are timely, professional and courteous in all of their dealings with me. I tend to think of them as an extension of my own business and an enabler to my success.
