Skype Outage Article

August 21, 2007

Jon Arnold and I were both quoted recently in a San Francisco Chronicle article titled Skype reveals outage source, tells customers it won't happen again. The article is extremely well-written, gets perspective from a number of people and weaves each viewpoint into a cohesive whole.   My quote follows below:  
The technology relies on user computers to route phone calls and handle some of the call authentication. There are thousands of computers and servers that are tapped to act as these supernodes in the Skype network.   That reliance has allowed Skype, owned by San Jose's eBay, to keep phone calls free between members and extremely cheap for calls to nonsubscribers. But an outage like last week's reveals the inherent vulnerability in the system when a large number of computers are affected within a short span of time, said Rich Tehrani, chairman of the Internet Telephony Conference and Expo and president of TMC, a communications and technology media company.   "The fate of the users is not in the control of one company, and that's the problem," Tehrani said.

Parlano

August 21, 2007

Bob Serr, Parlano CTO, took some time to give me this exclusive interview. In it, he gave some fascinating insight on the impact of industry giants like Google and Microsoft on the telecom world, and also let me know why Parlano’s presentation at ITEXPO is something worth looking forward to. One of the leaders in the burgeoning space of persistent group chat, Parlano gives some of the world's most dynamic organizations competitive advantage through more effective cross-functional group communication. You can read more about them in this recent TMCnet article.

I recently had the opportunity to speak with Erin Bolton, marketing manager of Acredo Technologies Inc, about IP communications, the company’s customer base and the upcoming ITEXPO.   Acredo Technologies delivers hosted IP phone service to the small business market and the company’s mission is to "Build and manage a recognized brand in the hosted IP-Centrex space for small business in North America.”   This past February TMC chose Acredo Technologies as one of the winners of its prestigious “Best of Show” at its Internet Telephony Conference & Expo.

Ingate

August 21, 2007

I recently had the opportunity to ask Olle Westerberg, chief executive officer Ingate Systems, about his business and the direction he is taking the company.   Ingate Systems produces a range of SIP-capable enterprise firewalls.   Please read the TMCnet article about Ingate Systems SIP Trunking Network for more information on the company.   Please outline your new corporate initiatives.   Ingate continues to lead the industry in SIP-enabling security technologies. We are once again working with our partners in the IP PBX and ITSP space to educate end-users, resellers and VARs on SIP trunking with the “SIP Trunking Series: Everything You Need to Know” at ITEXPO. We see SIP trunking as a way of making full use of the enterprise IP PBX, making it possible to use the IP PBX functionality outside the enterprise network. It is a critical stepping-stone to true global connectivity when everyone is able to connect with one another (both inside and outside the company) using the Internet.   Looking ahead, we support the trend toward unified communications as it paves the way for true global communications by providing users the flexibility to choose the best way to communicate at any given moment.   How is IP communications changing your company’s strategy?   Ingate has had SIP and IP communications in our strategy from the beginning.

I recently had the opportunity to ask Patrick Young of Arlinx about the company’s customer base, its IP communications strategy and the direction his company is taking.   The Arlinx IP Elite Security and Media Processing Platforms provide opportunities for developers, integrators, and resellers to offer an alternative to mainstream x86 appliances.   To learn more about the company, read this article published on TMCnet from earlier this year.   RT: Please outline your new corporate initiatives. PY: Our initiative is to produce an open IP communications application and specific hardware platform with strong authentication, encryption acceleration, a voice optimized media processor and very high energy efficiency.

What We Learned From the Skype Outage

August 20, 2007

As organizations move to VoIP and other forms of IP communications it is imperative they realize the world of IP is far different from the PSTN and circuit-switched networks of yesterday. While Internet Protocol is the protocol of the Internet which was designed to be resilient enough to withstand a nuclear attack, IP networks need proper management to be able to continue operating under a variety of circumstances.   The concept of the always up IP communications network was certainly in the spotlight recently as TMCnet’s Tom Keating broke the story of Skype, the world’s most popular IP communications software company having a major network outage. He surmised that a recent Microsoft upgrade to its operating systems was responsible for the outage.   A few days later, Skype explained that indeed, Microsoft’s operating system update coupled with a bug in the eBay division’s software was responsible for leaving millions without IP communications.   While some journalists have come to the conclusion that VoIP is no longer reliable because of this outage the reality is that a software bug stopped the network from functioning properly and this had nothing to do with the inherent reliability of VoIP.   Still, when you leverage the benefits of IP communications you must also be aware of the responsibilities that come with the technology. Yes, you now have some responsibilities you may not have been aware of.

IP Communications Education

August 20, 2007

Listen, I don’t want to overdo discussion of ITEXPO in my blog but the fact of the matter is this recent e-mail sent by my marketing team is a great document discussing what is important at the show. It is a good guide for you. What to see, where to go, where to be, etc.   You can see below the various aspects of Internet Telephony Conference & Expo which make it unique and the most imitated event in IP communications.

Skype P2P Problems

August 20, 2007

By now it seems the whole world is aware Skype had major problems last week. For most people, Skype was down. Tom Keating speculated the cause was a Microsoft patch which rebooted massive numbers of machines. He has a point as my machine coincidentally rebooted just before the Skype problem hit.   Many people thought Tom was incorrect but it turns out Tom nailed the problem.   Phil Wolf has an excellent recap of the problem with his thoughts and questions interlaced within.   For example, when commenting on the following from Skype:  
Normally Skype’s peer-to-peer network has an inbuilt ability to self-heal, however, this event revealed a previously unseen software bug within the network resource allocation algorithm which prevented the self-healing function from working quickly.
  Wolf wonders:  
If the bug was within the algorithm, in the Skype client, was the bug ever repaired?
