The Elephant in the Video Conferencing Room

The fundamental challenge of running enterprise-wide video conferencing (VC) is keeping users happy. Happy users feel empowered, not foolish when confronted with the challenge of setting up or running a VC meeting. If you keep users happy you have most likely cut support costs while increasing utilisation – both metrics critical to any AV service manager come review time.

However for some inexplicable reason the VC industry as a whole has done a very poor job of keeping users happy. Regardless of what the respective vendor marketing departments say, most VC users consider the experience to be at best annoying, at worst completely off-putting. Integrators try to put lipstick on the vendor-grown pig, but inevitably only add cost and introduce unneeded complexity.

Introduction to Session Border Controllers

High definition video conferencing is a standard right now. If it will change, it will only change to an ever higher definition such as Ultra HD (involving 4K and 8K). Virtual workplaces, telecommuting and working from home becomes more and more easy and so organisations go expanding, sometimes forgetting about network requirements ending up with new capacity limits or reduced quality of their video communication solution.

A Session Border Controller can help with many problems there might be, but it is not a remedy for every issue ever to occur on your video conferencing network. I wrote this article to give you some more insight into what a Session Border Controller is, what it does and how it can help your corporate communication.

What is a Session Border Controller?

A Session Border Controller is a network component designed to safely link networks with a different security requirement and setup. They are mostly utilised for VoIP and video conferencing networks to establish secure connection sessions. The Session Border Controller therefore allows control of signaling and transfer of media data in a secure way.

What can I do with a Session Border Controller?

Session management allows service providers to control the session routing, establish interoperability across environments with differentiating standards, enforce bandwidth policies or create an interface to a third party application. To keep it short and simple: A Session Border Controller optimizes solution performance and overall service quality, it allows a rapid service deployment or growth and it protects infrastructure from malicious attacks.

Who develops Session Border Controllers?

Based on Gartner’s Magic Quadrant for Session Border Controllers from October 2012, Acme Packet (recently acquired by Oracle) excels in execution as well as vision scope, making them the leader of the magic quadrant (see graphic). Other competitors are Huawei, Sonus, Genband, Metaswitch Networks, Dialogic, ZTE and Technicolor.

Magic Quadrant for Session Border Controllers by Gartner Research

Acme Packet is very interesting due to their focus on unified communications networks and even offering solutions especially designed for video conference networks of manufacturers such as Alcatel-Lucent, Avaya / Radvision, Cisco (including former Codian / Tandberg technologies), LifeSize, Polycom and Vidyo. Supporting and enabling interworking these technologies the Acme Packet solution avoids potential for vendor lock-in, protecting the investment made in video conferencing infrastructure and endpoints.

What are the technical functions of a Session Border Controller?

The functional scope of a Session Border Controller can vary, depending on what the individual device is designed to do. However to reflect a maximum of capability information, we would like to list the following functions that can be found in Session Border Controllers:

Connectivity

  • IPv4 / IPv6 interworking
  • SIP manipulation
  • NAT traversal
  • VPN connectivity
  • H.323 / SIP interworking

Quality of Service (QoS)

  • Traffic policies
  • Call admission control
  • ToS / DSCP bit setting
  • Resource allocation
  • Rate limiting

Security

  • Defense against DoS attacks
  • Can prevent toll fraud
  • No topology hiding possible
  • Malformed packet protection
  • Signaling protection via TLS and IPSec
  • Media protection via SRTP

Media processing

  • DTMF delay and interworking
  • Media transcoding
  • Tones and announcements
  • Data and Fax interworking
  • Support for Voice and Video calls

Regulatory

  • Call prioritization (e.g. for VIP usage or emergencies)
  • Auditing functions for internal audit or for law enforcing organisation
  • Business Intelligence, reporting, management information, source for billing information

Summary

Even though not a mandatory part for VoIP or video conferencing networks, Session Border Controllers have a great potential to add value to the communication services of organisations. The relevance increases for service providers companies as the functions described above can significantly increase the quality and performance of a serviced network.

The Benefits Of Wide Area Networking Using Cisco Technology

Long before the internet became the phenomenon that it is today, Cisco was providing networking solutions, so efficiently that it has become the world leader in computer, IT and communications networking. In fact, the company has become a household name, recognised even by people who haven’t a clue what Cisco does. This is why, to those who are in the know, Cisco technologies are the perfect choice when planning Wide Area Networking (WAN) solutions for anyone from home users to corporations operating around the globe.

Cisco Offers Bespoke Solutions

One of the most appealing advantages of using Cisco Technologies for WAN is the company’s flexibility to tailor its networking products and solutions to customers’ specific needs, meaning no prospective customer is only offered the choice from a range of off-the-shelf options. This also offers the scope for growth and future updates without installing a complete new system.

Connecting Through Switching

Wide Area Networking using Cisco Technology is where the company comes into its own. While many other providers have moved into the smaller Local Area Network and Personal Area Network markets, Cisco have undoubtedly looked at the big picture for the future and provide a service that is used and trusted across the globe. From a base or local station, information sent to a remote geographical location must travel via one or more WAN links, connected through switches that are dedicated to sending the information. A computer in London, for instance, would communicate through a router to a WAN that then sends the data to a router in, say, Munich, Montreal or Mumbai. Three different technologies, cell switching packet switching and circuit switching, are used, each with its own advantages, disadvantages and optimum uses.

Benefit From Unbeatable Flexibility

At the heart of all of the company’s products and solutions is the Cisco Internetwork Operating System, or Cisco IOS. The IOS brings together diverse and different systems and devices to integrate varied protocols into a cohesive whole system. The integration of all components of the network increases security, as well as speed and quality of communication. With these solutions available, network designers can work more freely and flexibly, delivering solutions to their customers in a smooth process.

Modern Communication with Cisco TelePresence

Using high-end video conferencing technology Cisco was among the first organisations to produce TelePresence infrastructure and endpoints alike. With the Immersive TelePresence suites they have reached a milestone that was unparalleled until now allowing important meetings to be carried out with participants from around the world with the same effectiveness as if they were all in the same room.

Cisco Technology Is Future-Proof

One reason that Cisco technologies lead the world is that the company has never stood still. It has acknowledged advances in technologies in networking and connectivity, which means that the company is trusted by a wide pool of users. Consumers and network specialists look to Cisco for future developments. Cloud technology is the latest development to have captured the imagination, but it will not be the panacea it is predicted to be without the nuts and bolts of everyday use. Whatever comes out of the cloud in the future, integrating WAN with Cisco technologies gives its users optimum usage out of their broadband and network to do their own jobs with the maximum of efficiency, while Cisco runs the system unobtrusively under the bonnet.

iRobot Ava 500: Next-Gen Telepresence Roll-About

Telepresence robots are not only a sci-fi part of TV shows such as the “Shelbot” as seen in “The Big Bang Theory”. A new telepresence robot has been announced: iRobot mounts Cisco EX60 TelePresence units on their cutting edge, auto-moving robots and introduces the iRobot Ava 500.

iRobot Ava 500 Introduction

The iRobot Corporation is an U.S. based company founded in 1990 and one of the pioneers of telepresence robot technology. Their portfolio includes robots for domestic use as well as solutions for police and military forces. Now they have introduced the Ava 500 and moving into enterprises and manufacturing sector by enhancing the iRobot technology with the Cisco EX60 TelePresence unit for HD video conferencing features.

Ava 500 is not only able to be remotely moved, but can also move autonomously to a target location without the effort of actually steering the unit. This enables the users to use the scheduling function to make sure that the Ava 500 robot is in the desired position at a planned time and date. All information about its position and move can be tracked on an app via iPad or iPhone and does not require in-depth technical insight.

In order to be able to move autonomously Ava 500 will make an “exploration” run when placed in a building for the first time. The area will be scanned and all information will be recorded on its location map, which then can be used by the user easily to tap to a location using only the touch screen of the iPad or iPhone. POIs, such as conference rooms or employees workstations, can be placed on the map for easy access. Even though the user does not actively have to steer the unit, it will still be possible to view the camera feed of the moving Ava 500 and to say “hi” to co-workers passing by. After a session is complete, the Ava 500 unit will automatically move back to it’s docking station to charge up again.

What is WebRTC? – Overview for Busy People

webrtc, logo, chat, bubble, shapes, colours, colorsNo other topic is roaming the news and social media as much as WebRTC these days. But what is WebRTC and what should it mean to you?

Today I would like to give you an overview around this trend and where it came from. In this article I would like to try out the “For Busy People” article format by consolidating all hot topics into quick facts to add value to you without getting side-tracked. I know you busy people are busy and so you can just skip the parts of the article that you are not interested in.

What does WebRTC stand for?

WebRTC means Web Real-Time Communication, so we are talking about ways to communicate without any delay, based on a web-browser, without the use of software that needs to be installed beforehand.

What is WebRTC?

WebRTC is an open framework for placing real-time communication components on web-pages and is controlled by the World Wide Web Consortium (W3C), who are also taking care of other web-standards such as HTML, XML, CSS and others. WebRTC components could include methods such as VoIP, Instant Messaging (or just “chat”), video conferencing or a combination of these. Personally I would count WebRTC to the umbrella of Unified Communications, but the actual use of the WebRTC solutions depend on each enterprise.

Where does WebRTC come from?

WebRTC technology was first developed by Global IP Solutions (or GIPS), a company founded around 1999 in Sweden. In 2011 GIPS was acquired by Google and the W3C started to work on a standard for WebRTC. Since then Google and other major players in the web-browser market, such as Mozilla and Opera, have been showing great support for WebRTC.

How does WebRTC work?

The framework is based on HTML5 and JavaScript but does not utilise SIP or H.323 like other Unified Communication solutions. The signalling and transfer of data works over RTP and with an XMPP extension called “Jingle”. With the newly introduced JavaScript Session Establishment Protocol (JSEP) direct connections can be established without the need of a piece of hardware in the middle. Depending on the deployment audio, video and / or other data can now be exchanged to allow WebRTC to happen in your browser.

And for our firewall traversal specialists: WebRTC can do STUN, ICE, TURN, RTP-over-TCP and supports proxies. What else do you wish for?

What does WebRTC mean to me?

Imagine the impact of 1,000,000,000+ endpoints. Not bad! This is the potential amount of endpoints talking to each other and making VoIP calls or even video conferences. Even though Microsoft is strongly pushing Skype for desktop video conferencing, they are also making sure that their Internet Explorer is ready to take on the WebRTC challenge.

But the missing link right now is: Will there be interoperability between WebRTC and other Unified Communication solutions? I believe the first developers, making both worlds compatible to each other will have edge.

Examples for WebRTC?

The possibilities are impossible to count. Especially in the age of BYOD everyone has their smartphone always ready and beyond that every notebook and desktop PC could participate in WebRTC. Here are some examples I could think of:

  • Customer service via video conference (the end of the service hotline?)
  • Working together on documents via web (web-collaboration beyond firewalls)
  • Smart-TVs allow you do do video conferences without infrastructure or service running in the back (if there’s a browser – there’s a way!)
  • Not interested in video conferences? Have a video diary! (takes only cloud storage and WebRTC)
  • WebRTC might change the face of Social Media platforms like Facebook, LinkedIn and Twitter completely if implemented (why not quickly talk about it?)
  • Instead of displaying phone numbers to your common window-shopper, provide a QR-code or a NFC space, so users can reach directly to you with their smartphone or tablet (we got a camera, a mic, a speaker – so let’s use them!)

Is there a WebRTC presentation?

You are lucky! Google has recently released a web-based presentation with a lot of interesting slides. I have also added a video below, for your to get some more details on WebRTC, Let me know of your thoughts!

Personal Telepresence – Software Solution Comparison

Telepresence on your desk is a great enhancement to the benefits of video collaboration. It enables you to join meetings ad-hoc and (at least for me) replaced the need for doing a phone call. Even if hardware based endpoints are not available there are software solutions available for personal telepresence.

Throughout 2012 I have been using a hardware-based endpoint for quick communication via video and since January 2013 I switched to a software-based solution. I tried out a few and wanted to share the comparison with you.

In the personal telepresence solution comparison below, I listed several options on personal telepresence software clients or web conferencing solutions with video conferencing functions. You will also find links to each solution further down, in case you would like to get more details on the products.

My requirements

In the comparison we considered most features and functions but to keep it short and sweet, we published only the most popular and relevant ones. For myself I have a strong focus on security and encryption as well as the ability to call all other H.323 based endpoints and infrastructure devices. With the Videoconference24 client for example I am able to call any box no matter if it is from Huawei, LifeSize, Cisco, Radvision / Avaya, Polycom or similar manufacturers. As long a software-client supports standard SIP or H.323 calling those is also possible – you get the idea: I want to reach them all and I want my line secure even through public internet!

Beside that I enjoy the ability to invite for multipoint video conferences without reserving resources on a separate MCU. In most cases this would cost money yet again and like this I can completely cut both the invest in MCUs as well as starting a video call for right now, without booking nor calling anyone to prepare my conference. Of course video conferencing managed services do make sense in many occasions but just for a sudden meeting I don’t need someone on top of things.

Participants of comparison:

There are more solutions than that available and if you would like to add the solution you have good experiences in please feel welcome to let us know in the comment section below. As usually I am more than happy to update the comparison in collaboration with you.

Summary

I am now using the Videoconference24 solution provided by Global Media Services and don’t have a broken heart when I think back to my hardware-based endpoint from last year. Just one thing I would like to add is that when you are saving big-time money going to software-based solutions: Get high-end peripherals for it! You don’t want to be the VGA person in a HD call because you are using the old webcam back from the days. Recommended gear (in my books) comes from makers such as Logitech and Jabra.

What are you using? And … are you happy with it? I want to know your opinion!
