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.

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.

Desktop Video Conferencing – The largest Trend in Video Conferencing Business

Why are Desktop Video Conferences getting more and more popular?

The latest Forrester Report proofs again the importance of video conferencing and the continuous increase of desktop video conference solutions, integrated video conferencing rooms and immersive telepresence installations in organisations. The majority of the 1,000 participating companies stated that they are looking to implement desktop video conferencing solutions very soon. More than 40% of these organisations said also they are planning to introduce HD video conferencing and 25% are going to install immersive telepresence rooms solutions.

Desktop, Video, Conference, VC, Skype, Call, Lens, Camera, Close-up, Macro, Dust, Boke, Bokeh, Background, Blurry, Telepresence, Lync

This means…

There is an especially strong trend towards software video conferencing solutions, that can be used with already existing hardware such as PCs, Notebooks, Tablets and Smartphones. This is an important reason for the spreading of this kind of video communication technology in organisations but the main arguments for this are the reduced costs for installation and maintenance in comparison with HD video conferencing systems or immersive telepresence rooms.

Who’s new in the game?

The report provides a good overview around the current situation of the communication market and the manufacturing companies. The result is that next to big players such as for instance Cisco, Polycom and LifeSize, who are providing a wide range of video conferencing and unified communications solutions, several new companies are emerging, who provide software solutions. Two of the most important features of these new companies are a strong product focus and tailoring the technology to suit the clients. The report names some of the new actors in the game to be Vidyo, Huawei and Teliris.

Summary

Forrester shows clearly that many organisations are considering video conferencing as a strategic advantage and that the technology is placed in their long term planning for corporate communication.
