Microsoft digs into its deep pockets to snatch up Skype

The Wall Street Journal reported earlier tonight that Microsoft was in talks to purchase VoIP company Skype for between $7 billion and $8 billion. Kara Swisher just recently confirmed the acquisition in her BoomTown column, starting that the deal is worth an estimated $8.5 billion. 

Earlier reports stated that Google and Facebook were duking it out to get a piece of Skype, but in the end Steve Ballmer and Microsoft's huge chest of cash put an end to those discussions. The earlier reports also pointed to a Skype valuation of $3 to $4 billion, so Microsoft's $8.5 billion purchase price hopefully will bring a hefty ROI.

For those keeping score, eBay bought Skype in 2005 for $2.5 billion. Four years later, eBay sold a 65% stake in the company for $1.9 billion.

The first beta of Skype was introduced in 2003, and as of December 2010, it had over 663 million registered users. The average number of monthly connected users is much lower, however, at 145 million. And when it comes to users that actually pay for the service, the numbers drop down to just 8.8 million. 

Registered users can make Skype-to-Skype calls and one-to-one video calls for free. Users can make Skype-to-phone calls at a rate of 2.3 cents/minute. Skype also offers subscription plans at a rate of 1.2 cents/minute. 

We'll have to wait a few more hours until we get all the juicy details on Microsoft's latest acquisition, but we're betting that the boys from Redmond plan on tightly integrating Skype with Windows Phone 7 to better compete with Google Voice.

Well, the news is now official. Microsoft just announced that it is acquiring Skype for $8.5 billion in cash. Microsoft says that Skype will bolster its "existing portfolio of real-time communications products and services."

As expected, Skype will be tightly integrated into the Xbox 360 and Windows Phone 7 platform. Microsoft is also creating a new business division called the Microsoft Skype Division, which will be headed by Skype CEO Tony Bates (he will report directly to Microsoft CEO Steve Ballmer).

“Skype is a phenomenal service that is loved by millions of people around the world,” said Ballmer. “Together we will create the future of real-time communications so people can easily stay connected to family, friends, clients and colleagues anywhere in the world.”

“Microsoft and Skype share the vision of bringing software innovation and products to our customers,” said Bates. “Together, we will be able to accelerate Skype's plans to extend our global community and introduce new ways for everyone to communicate and collaborate.”

I assume you mean line problems creating errors or something to that effect, cause routers really don't do anything to the packets.

Should have clarified point 3 better than I did, but you are correct.

Also, packets don't really get lost during transmission, they usually just get dropped due to buffer overflows on an input queue (whether that be hardware or software).

Actually, packets can get lost in transmission.
What I mean by "Transmission" is the sending of data from one machine to another over an internet connection.
Those packets can get sent through dozens of different routers located along the way to the recipients machine.

What happens if: The router has a heavy load that it cannot handle? Has a fault? Or some other problem? The packet obviously can't get through or processed, so it's deemed "lost". (Dropped is just another word for it, semantics.)

Also if you ever do a 'ping' in command prompt, at the end of the ping it will give you a percentage of the packets: received, sent and lost.

I figured it was probably a clarification issue, just struck me as odd.

Usually router CPU load isn't an issue, as most things on carrier routers are done in hardware. The packets are rarely punted to the main CPU as this would slows things tremendously. The buffering issue is usually the only real problem as you are hard pressed to find real faults in carrier grade networking equipment.

A lot of reachability issues that you see with PING are caused by link/route flaps which usually stem from faulty lines or ports. ICMP packets are quite small and usually don't run into buffer issues. Another fun problem that can cause random packet drop is when load balancing is used and one of the paths is dead down the line, but no local indication is seen so the path is still used as if it were up. This is where things like SLA tracking are helpful as you can assign weights to links based on SLA and if a link goes down, you can pull the path out instead of having some traffic black hole.

There is a lot more to it and I won't bore you with the details, but networking is a wild world now as there are so many methods to route, balance and buffer.

Full disclosure: I am a core network engineer for a carrier, so I have to plan and design around this sort of stuff.

If you're a core engineer you're probably leaning more towards the Juniper side right?

Only thing I've seen with routers causing VoIP issues is with Cisco. They have a "sip fixup" feature on their VPN concentrators and some other routers/switches that just utterly mauls SIP traffic. Cisco has like 4 different implementations of that protocol depending on which product you use. All of them show age the moment any 3rd party interoperability is attempted.

Few products use SIP over TCP now so the problem is fading on it's own. You can't maul stuff encapsulated in TLS.

Agreed on ICMP.. you gotta kick up the packet size to find BH routers and latency/loss. Fun trivia: checkout what PING uses for a payload in larger packets. :)

When it comes to VoIP though the absolute #1 factor in call quality is the sound device used. You can run SONET over fiber to your house and still not compensate for a crappy microphone.

Pure Cisco, transport and all. I haven't really touched the Juniper stuff, but I know it is pretty nice. Cisco still has a hefty margin in the carrier space, you'd be surprised who runs Cisco all over. Only carrier I know of off hand that runs Juniper is Level 3.

The fixup was an issue on the old code, that has been gone for a long time. Fixup was the PIX version of the current inspection that is used in the new code. The new products work fantastically actually, the SIP inspection is very robust on IOS and ASA code. The whole firewall inspection change is quite robust, being able to just inspect ISAKMP and it will pass all related traffic for IPSEC, really nice stuff.

If you see the 8.4 ASA code and the new 15.1 IOS code, they are very similar now. Cisco really made some great changes with the ASA product line. I have had very few issues with anything Cisco on recent releases. The packet tracer feature they added to ASA code is awesome.

I dislike voice for the most part, so I stay away from it. I enjoy QoS setup and queuing, but bits are bits as far as I am concerned, I just move them around.

Might be the wrong guy to ask since you stay away from voice but do you know if SIP fixup supports extensions now?

Kindof a moot point with Lync at least. It no longer supports unencrypted TCP for clients.

Not a clue, you are better off using the policy map with inspection now. I believe they introduced that in the 7.x train. Funny, cause I'm setting up an ASA right now, ha.

Fun side note if you are interested

You can log into core looking glass route devices and see all the Internet routing tables. If you click on the AT&T one at the bottom, you can drop into one of AT&T's 7206VXR routers and play with command line. You will need a telnet program like putty.

When you get in, you can run commands like "sh ip route" or "sh int" to see some of the stats (without the quotes of course). You can also do "ping" and "trace" if you wish. You can see how long routes have been up, things like that. You are pretty much free to fiddle with it as you don't have enable mode, so you can't do anything dangerous with it.

There is an example of the output, you can see some packets got dropped from the buffer (queue). It is pretty minimal considering the sheer amount of packets going through, but it happens here and there.
