How Does IPv6 Impact Telecom Networks? Join This Free Online Session Tomorrow To Learn...

How does IPv6 impact telecommunications networks? How will IPv6 affect the SIP protocol? If you work in telecom, what should you be aware of with regard to IPv6? With World IPv6 Day only a week away, if you have been wondering about these kind of questions, please feel free to join me live in a free session hosted by the US Telecommunications Association:

IPv6 and Telecom Networks
Thursday, June 2, 2011
1:00pm US Eastern

Registration is free and if you are unable to attend it will be recorded for later viewing. (And if you register now, you'll be notified when the archive is available for viewing.) The description of the session is:

The networks that make up the Internet and IP communications are in the middle of a sea-change with the transition to IPv6. What impact will IPv6 have on telecom and communications networks?

Join USTelecom and Voxeo for a look at the various challenges that telecom and broadband services providers face in keeping their communication services working while transitioning to IPv6.

I'll be explaining briefly why there is all the attention on IPv6 then getting into the basics of IPv6 addressing. After a brief overview, I'll then dive into how IPv6 affects the Session Initiation Protocol (SIP) and get into some technical detail. I'll then wrap up with some resources about how to learn more and get started with IPv6 and finish with a Q&A session.

If you attended the Voxeo Developer Jam Session I presented back in May on IPv6, I'm going to be covering basically the same material although with a vendor-neutral perspective (i.e. I won't be explaining and demonstrating how Voxeo Prophecy and PRISM now natively support IPv6). Obviously the live Q&A session will be new, too, and I find the questions around IPv6 always quite fun to discuss.

Please feel free to join us at 1pm US Eastern tomorrow. Registration is free - and if you can't join live the session will be archived and available for viewing on US Telecom's website for 90 days. With World IPv6 Day coming up on June 8th, it's a great time to learn about what is going on with IPv6!

P.S. If you are interested in IPv6 in general, you may be interested in the IPv6 Resource Page I put together for Voxeo at:

http://bit.ly/voxeoipv6

Lots of good links to tutorials, VoIP resources and more...

IETF 74 starts next week in San Francisco...

The 74th meeting of the Internet Engineering Task Force (IETF) starts Monday morning out in San Francisco. As usual there is a packed agenda with a lot of great discussions going on. This one is particularly interesting for those of us involved in the "Real-time Applications and Infrastructure (RAI)" area - which is all the various working groups related to SIP and other real-time communications protocols - as there are some proposals moving forward to rather fundamentally restructure the ways in which SIP-related work moves through the IETF. I expect there will be many involved conversations going on out there next week.

As much as I would like to be there, I won't be physically out at IETF 74. It's not my new role at Voxeo keeping me away, but rather this... oh... wee minor little detail that my wife is now five weeks from giving birth to our second child! :-) At this stage of things I'm severely limiting my travel - and flights across the country are definitely out.

Instead I'll be participating remotely, listening to the audio streams and joining in the Jabber chat rooms. Probably writing about some of it over on the "Speaking of Standards" blog I write in from time to time. The great thing with IETF meetings is that you can participate remotely (albeit obviously not to the same level of effectiveness as being in the room).

Lots of good stuff going on...

Want to understand Peer-to-Peer SIP (P2PSIP)? Listen to this podcast...

What if we could design SIP-based VOIP systems... but without any servers? What if we could have SIP endpoints just communicate with each other and "self-organize" into networks? What if we could essentially build an open standards-based version of Skype? How would it work? Who would use it? How would we secure it?

Those are all questions we discussed in the Squawk Box podcast / interview I did with David Bryan on July 10th. David is the co-chair of the IETF's P2PSIP Working Group and also the CEO of SIPeerior Technologies. It was a great interview where we covered all these questions and much, much more.

P2PSIP, to me, represents one of the most exciting new directions for SIP research and is something I'm definitely following closely. I wrote about my interest in P2PSIP clouds (and connecting them to larger clouds) at some length over on Voxeo's Speaking of Standards blog... it's all about clouds of SIP communication... and how we weave them all together. It's a fascinating time.

If you'd like to understand what P2PSIP is all about, please do definitely check out the Squawk Box podcast... and then, if you are so inclined, head over to P2PSIP.org to find links to learn more and download code...

Down at IETF 71 in Philadelphia this week

This week (March 10-14) finds me down in Philadelphia for IETF-71, the 71st meeting of the Internet Engineering Task Force (the people who write the standards for the Internet). I don't honestly know how much I'll be blogging here on this blog. I do hope to be writing some over at the "Speaking of Standards" blog on Voxeo's site. We'll see. These meetings tend to be rather intense.

If you'd like to follow along with what's happening here at IETF, I've written up some instructions about how to join in the audio streaming and IM group chats. I've also posted what I think will be my schedule, which will give you a sense of what the various VoIP-related sessions.

That's the news...

As I wrote over on Voxeo's "Speaking of Standards" weblog, one of the ironies of the language we use in this space is that we all have been talking about "SIP trunks" for a few years now, but nowhere has there actually been a formal definition of what exactly a SIP trunk really is!

Jonathan Rosenberg has now offered a definition in a new Internet-Draft titled "What is a Session Initiation Protocol (SIP) Trunk Anyway?" Here is the abstract:

The term "Session Initiation Protocol (SIP) Trunk" has become almost commonplace amongst vendors and SIP providers. Even though the notion of a 'trunk' has a well defined meaning in circuit switched systems, it has never been defined for SIP. This document provides a formal definition for a SIP trunk, discusses its scope and applications, and establishes best practices for identification and security of SIP trunks.

The document makes for good reading even if you are not overly familiar with the concepts behind SIP trunks. Jonathan is looking for feedback and there will I'm sure be continued discussion on this topic.

IETF "RUCUS" BOF to be held about SPIT...

Over on the Voice of VOIPSA blog today I posted about a new session has been approved for the IETF 71 meeting coming up in Philadelphia in March called "Reducing Unwanted Communications using SIP" a.k.a. "RUCUS".Hannes Tschofenig, who submitted the proposal, has created a RUCUS web page and is looking for feedback. I'm planning to be at the RUCUS session at IETF 71 and would encourage others who want to talk about voice spam / SPIT to join in as well!

A video greeting from IETF 70 in Vancouver

I was up way too early out here in Vancouver, so I wandered over to the show hotel and recorded a little greeting:

Introducing "Speaking of Standards", a new Voxeo blog about industry standards, IETF, W3C, SIP Forum, etc.

A large part of why I have NOT been writing here all that much in the past few weeks is that I've been busy in my new role with Voxeo working on a corporate blog portal. I've been covering a bit of that odyssey over on my Disruptive Conversations blog as well as in my weekly reports into the For Immediate Release podcast. It's been a great amount of work but also a lot of fun - I've been very lucky to have a colleague who does amazing things with CSS and graphics, and so the sites look a whole lot better than they would if I were left to my own devices.

I'm very pleased to say, now, that we've reached the point where I'm willing to link to our work and talk a bit about what we are doing. The main blog portal is the predictable "blogs.voxeo.com" but the weblog that we're really starting to use and could be of interest to readers of this blog is our "Speaking of Standards" blog found at:

http://blogs.voxeo.com/speakingofstandards/

I've obviously been very occasionally writing here about standards and some of that may continue, but I expect most of my writing on the subject will now occur over on this new Voxeo weblog - and I'll naturally be writing more on the subject. We'll be writing about the IETF and SIP standards, but also the W3C and standards such as VoiceXML and CCXML that I've never covered at all here. We'll be linking to events and tutorials we find and generally providing whatever information we can about standards affecting our industry, as well as Voxeo's views and implementations of those standards.

Why would Voxeo sponsor a weblog about standards? Primarily because the company and our products are all about open standards - which was one of the things that attracted me to the company after they first approached me. I've since learned that they've been leading the IVR industry in adopting open standards. As the products page says in the "Fast Facts" sidebar:

• 100% Standards based IVR
• Supports W3C VoiceXML 2.0
• Supports W3C CCXML 1.0
• Supports W3C SRGS 1.0
• Supports W3C SSML 1.0
• Supports CallXML 3.0
• First platform with XML call control
• First platform with XML conferencing
• First shipping CCXML implementation
• First SIP/VOIP IVR platform

Not bad, eh? Add to that the fact that our CTO (my manager), RJ Auburn, chairs the W3C's Working Group on CCXML and we've hired other folks involved with standards efforts... all of that is why we added a weblog on standards.

So if you would like to see our view on industry standards, find tutorials about various standards or learn about standards-related events we may be attending, I would invite you to come on over and check out "Speaking with Standards" - or subscribe to the RSS feed. While I (and others) will still be working on improving the site, it's mostly done and I'm delighted to be able to return to writing more. Let us know what you think!

I'll be out in Vancouver Dec 2-7 for the 70th meeting of the IETF.

Just confirmed travel plans today - I will be heading out to the 70th meeting of the Internet Engineering Task Force (IETF) in Vancouver, British Columbia, Canada, from December 2-7. If any readers will be out there (either for the IETF or in Vancouver in general), please do drop a note and let me know. This will be my first meeting in my new role with Voxeo and I'm very much looking forward to renewing old acquaintances and also getting more directly involved with the work of the IETF.
