Video Conferencing via Mobile Devices

Video Conferencing via Mobile Devices

Video Conferencing on Mobile Devices Your boss just told you that you have to make video conferencing available to Lync or Skype for Business mobile clients or Cisco Jabber mobile device clients. Just don’t do it! Joking aside, of course it’s not avoidable. Traveling associates and executives can save a lot of money talking on video conferences or even less bandwidth-intensive IP Voice clients compared to global roaming cell phone charges or even hotel phone charges. Most hotels worldwide offer WiFi, and connecting to conference calls and video conferences via a mobile client application is feasible. However, almost certain difficulties...

NAT, Firewalls and Video Conferencing

Bottom Line: Firewalls perform NAT. NAT and video conferencing standard protocols were initially incompatible. Solutions arose and exist for video conferencing to work through firewalls that perform NAT.  Some solutions include advanced firewall capabilities, some involve systems installed in DMZ networks, some include all of the above. As usual in IT and networking technology, implementations of standards across vendors may vary, and feature compatibility and performance impact should be thoroughly analyzed. NAT Origins As covered in a previous post, RFC 1918 was released even before Network Address Translation was a mature technology. However, the need for entire enterprises with hundreds...

RFC 1918

The Internet Engineering Task Force (IETF) sets many of the policies related to the Internet and communication via the Internet Protocol. IETF standards are published as “Request For Comments” or “RFCs.” RFC 1918 sought to address the eventual exhaustion of IP addresses, which we have since experienced. It introduced and standardized the concept of “private” and “globally unique” IP addresses. RFC 1918 defined the following ranges as “private IP addresses:” 10.0.0.0 – 10.255.255.255 (10/8 prefix) 172.16.0.0 – 172.31.255.255 (172.16/12 prefix) 192.168.0.0 – 192.168.255.255 (192.168/16 prefix) That is, it determined that any address within these ranges would not be routable on...

HD Video Conferencing Over the Internet and QoS

As discussed in a previous post, HD video conferences consume more bandwidth than those with Standard Definition video. More pixels per frame, more data per frame, same number or more frames per second—it makes sense. QoS for Video Conferencing How can you ensure you will be able to connect and have a quality conference? Make sure your sites are equipped with plenty of bandwidth for HD video conferencing. Enable and configure QoS on your private MPLS WAN links in case they are not. QoS configurations essentially assign classes to packets. Each router in the potential path of QoS-marked traffic has...

HD Video Conferencing

HD video conferencing (High Definition) depends on the ability to send and receive data at higher speeds, and for the cameras and displays that comprise the video conferencing endpoints to capture and display the audio and visual data within HD Video standards. Since it is important that all video conferencing system components match each others’ capabilities and specifications, a brief overview of standards and nomenclature, and how they evolved, may help. Video Standards As technology improves, video monitor manufacturers have been able to control increasing numbers of pixels per square inch of display surface. Video formats that could exploit these...

Self-Hosted Video Conferencing Solution or Cloud-Based Video as a Service?

This is a very good question, and one that many business and IT executives ask every day. Video conferencing lets the participants see each others’ body language, reactions, facial expressions, etc, and, as a result, communicate more effectively than in typical audio conferences. It helps reduce travel and related expenses for meetings. More businesses want to use it. Technology is bringing it within their reach. Like all good tools, each approach to implementing online video conferencing has its merits. The decision to implement a video conferencing solution should include the evaluation of several variables which are mostly concerned with network...

Video Conferencing

Either of the terms “videoconferencing” or “video conferencing” suffice to describe a face-to-face meeting or discussion held between two or more parties in two or more locations by means of audio and video technologies. Video conferencing systems have been around for a long time, but advances in data network technologies resulting in the growth and ubiquity of the Internet have accelerated their widespread adoption. Originally so expensive only large businesses could afford video conferencing systems in “board rooms,” the equipment needed to have a face-to-face meeting is now built-in to mobile phones, tablets, and laptops. The entire set of audio,...

Welcome to Online Video Conferencing

Video conferencing technologies have been advancing at a  pace similar to that of data center and other Information Technologies.  In a short time span, multi-party and multi-location conferences became the norm. The novelty of conducting a successful corporate video conference has evolved into an expectation of conferencing via any device from anywhere. High quality, hi-def video and audio are expected, but carry their own unique implementation challenges. Security concerns, firewall rules, network capacity and component throughput determine where systems are logically installed in a network. No two companies are the same, no two networks are the same, and no two...
