LEGO® brick analogies are overused. I’ll accept that. Nevertheless, this is the best I can do at the moment, so please bear with me. The simplicity of the base element – The Brick itself – is amazing. The ability to universally click together bricks of different sizes and colors created the whole universe of “things”. Let’s just look at some facts: There are more than 300 million kids playing with LEGOs worldwide (not accounting for hordes of willing

It seems like everywhere you go, checking for standards, there are at least two for the price of one: PAL and NTSC, DVD-HD and Blu-ray. H.323 and SIP. SIMPLE and XMPP. Why can’t we just get along and decide on a single protocol for each task? One ring to rule them all? They used to call it “convergence”. In the distant past, when people were looking for a nicer word for “VoIP”. It meant all types of devices talking

I’ve already coined the term “unattended software spoils faster than yogurt in the desert sun.” It deals with my preference of hardware over software. I guess that having this come from a software guy is a bit weird, but it is still true. In regards to the visual communications industry, it applies even more. We’ve just released our BEEHD product, which allows others to build and manufacture hardware based videophones. We’ve also just announced our partnership with Samsung, together creating

In a previous post I asked if XMPP is going to be a successor of SIP and that has brought a lot of attention and a new nickname to me (Radvision guy), which I gladly bear in honor after 10 years at RADVISION. That said there are few things that need to be stated about SIP’s complexity and XMPP’s clean architecture. To better show and explain the complexity that is involved here, I will show you a graph that was

If you look at SIP today, it is the most widely used protocol for VoIP when it comes to developing telephony services. In a way, it overthrew H.323 in most areas. On the other hand, in the past several weeks I’ve been bumping a bit more into XMPP. To some it may seem as if XMPP is set to overthrow SIP as the VoIP signaling king. XMPP is Becoming a Swiss Army Knife I have already tried comparing XMPP with

You can do everything with SIP: Voice over IP, video telephony, presence, instant messaging, SMS, MMS and much more. Sometimes it feels like SIP is a protocol invented by a salesman: “Oh, you are looking for a solution that starts the microwave when you get to your driveway after a long day? Sure we have it – SIP!”Last week I wrote about XMPP versus SIMPLE, where both are used for presence and SIMPLE and utilize SIP for its transport. A

Presence is always positioned as the key to unified communications (UC) – at the very heart of UC is the ability to discern the current status of people and resources. Which protocol will be the one used to power Presence? SIMPLE or XMPP? XMPP XMPP stands for “Extensible Messaging and Presence Protocol”. It is a streaming based protocol that routes XML messages between entities. It is mainly used for presence and instant messaging although other uses for it exist
