Skype's growth and superior network

Skype is quite a success story. Their story is remarkable, to say the least. Some things do need to be noted. I thought that the growth would be exponential, but the rate seems to have decreased a bit, maybe just a temporary breather for it to become more of a household name. A lot of early adopters have already embraced it, despite their distrust of proprietary software (read: contemporary Open Source frenzy).

Skype is the de facto VoIP standard, and I think that the emergence of even easier to use equipment and more mainstream acceptance will usher even more interest for this telecommunications revolution. The paradigm shift from a server-client based framework to a P2P system heralds an extremely robust network, an Internet within the Internet, so to speak. Scalability and larger userbases will not strain centralized servers (deteriorating quality) but will increase Peers (or nodes, in Skype lingo) and thus improving quality. In economic terms, the marginal cost per extra user is negligible.

Basically it boils down to each user (peer) offering a bit of their connection to relay the conversations of others. If any user wishes to sign off whilst someone else is using their connection, the calling party won’t notice a considerable loss of quality since the call is simultaneously being routed via multiple nodes.

99% of it is in fact P2P, only the login and creation of a username will require authentication on a centralized server. Once that is done, all calls are dealt via Peers. Skype has other services, such as voicemail, call-forward, SkypeIn and SkypeOut. The first two require storage in a centralized server, the latter two require a gateway to and from the POTS (Plain Old Telephone System)
network.

With roughly 210 million broadband subscribers, each with a few users, Skype still has quite a way to go. Competition is also around; gTalk, Project Gizmo, MSN to name just a few. It's going to be exciting!

As for the measurements: These represent the dates when the milestone amounts were reached. The actual amount of online users depends on the time, most users are online around 16:00 CET, not in the weekends.

Poll of the week

Numsum

You know, you should really get to learn how some of these things work... like this Numsum - I'm using an iframe to get this done... and it's quite amazing.. it's the future of computing I tell you.

Monkey see, monkey do

I've never seen anything like this happen in a metro. Have you?

Ghost Car

I saw this ad a long time ago, just wanted to share it with you...

Huge explosion in a residential area

This happened a few years ago, in a city called Enschede, the Netherlands. Quite a number of people died. For the ones who don't speak Dutch, the last comments are, "the roofs are literally blown off the houses".

Suitable for Work?? Just someone dancing

I love Google Video... and you'll love this clip (for the music of course)... I just wanted to share that with the world.

WRC Racing

I think this clip is just amazing...

Google Calendar here?

The best way to start a New Year is with a new way to keep track of what you're doing. I'm pretty sure that our buddies at Google are working on Google Calendar. The URL used to send you to www.google.com but now you see the URL is still http://calendar.google.com - I can sense that it's coming!!!

PS. HAPPY NEW YEAR to all!
