This document analyzes delays in unicast video streaming over IEEE 802.11 WLAN networks. It describes conducting an experiment using a testbed with a Darwin Streaming Server and WLAN probe to capture packets. The analysis found that video bitrate variations, packetization scheme, bandwidth load, and frame-based nature of video all impacted mean delay. Bursts of packets from video frames caused per-packet delay to increase in a sawtooth pattern. Increasing uplink load was also found to affect delay variations.
Proxy Cache Management for Fine-Grained Scalable Video StreamingVideoguy
This document proposes a novel video caching framework that uses MPEG-4 Fine-Grained Scalable (FGS) video with post-encoding rate control to achieve low-cost and fine-grained rate adaptation.

VIDEO CONFERENCING TODAY
INTRODUCTION
Since its first commercial introduction in 1982, when video conferencing was expensive, could
only work over limited networks and was primarily used for talking heads, video conferencing
has evolved to the point that the technology available today is nothing like what was available
in 1982 or even what was available two years ago. In other words, it is NOT your father’s video
experience any more! In recent years, the growth of video conferencing has been driven by
mergers & acquisitions, corporate downsizing, the drive to control costs, a need to reduce
response times, negative events (i.e. war, weather, and illness), and decreased costs and
increased functionality of video conferencing technology. Video conferencing has become a
valuable tool for many vertical markets, including education, government, healthcare,
manufacturing and finance, among others. Vendors have designed the technology to meet
specific user needs from individual desktop systems to completely integrated rooms that truly
make users feel “like being there” when meeting with distant sites.
Video conferencing, coupled with collaboration, allows increasingly dispersed organizations to
pull their human and information resources together to create new ways of working,
interacting, and responding to customers and partners.
Worldwide, organizations have heavily invested in computers and communication networks and
are now focusing on getting better returns from that massive outlay by seeking new
applications that can bring real benefits to the organization. Near the top of the list is
conferencing and collaboration. The demand for real-time, high-quality communication tools is
driving the growth. No longer just a way to hold telephone-style conversations with pictures,
video and data/web conferencing exploit the power of the underlying technologies to build
stronger, more valuable organizational networks:
• Networks of people,
• Networks of information and ideas,
• Networks of expertise.
VIRTUAL TEAMS REPLACE THE TRADITIONAL WORKPLACE
Today, geographically dispersed work teams are the rule, not the exception. Video
conferencing offers the benefits of face-to-face communication without the inconvenience,
wear-and-tear, unpredictability, and expense of traveling to a meeting. But is doesn’t just
displace travel – it is a better way of communicating for all but the most exacting interpersonal
contacts. The fact is that speech is only a small element of human communication. Without a
visual dimension, conversations can do little more than facilitate information exchange. That’s
Page 3 of 12
4. Video Conferencing Today: it’s NOT your Father’s Video Experience
because research shows that approximately 80% of what is communicated when people
interact is conveyed visually – through body language, gestures, facial expressions, and other
visual nuances. People better understand and remember more of what they see than of what
they have only heard.
HOW ORGANIZATIONS BENEFIT
The use of video conferencing has the potential of increasing productivity and efficiency
by reducing unproductive travel time, preventing meeting delays, creating shorter and
more structured meetings, and providing faster exchange of information. This allows for
greater reach of message, since individuals may now obtain information when it is
convenient for them. Video conferencing also allows for an increased number of
participants and allows people who might never meet, yet who work together, to meet
virtually – face-to-face over video. With video conferencing, and the data collaboration
tools that are now used with it, all individuals who need information can get the
information when it is easiest for them, on a real-time or delayed basis. By increasing
usage, organizations will quickly see a financial return on investment.
Video conferencing is usually adopted by an organization for a combination of three
productivity-enhancing reasons:
• To reduce the need for people or work teams to physically reside in the same
place.
• To enhance teamwork and collaboration within organizations by offering a high
level of intimacy and interactivity.
• To collaborate on a document or graphic creation, with insertions, deletions or
alterations made to the document by any participant in real time.
As a result, users find the benefits of video conferencing to include faster decision-
making, reduced time to market for products, interface with scarce talent when needed
(regardless of where they are located), better customer responsiveness, and more
efficient work practices.
Users like a technology that is transparent to them and easy to use, allowing them to conduct
business independently and efficiently. If used with purpose, video conferencing can help users
be more strategic and competitive. Users want to improve productivity, increase access to
subject matter experts, and allow meetings to be held when needed. Of course, in many
instances, travel costs are also reduced.
USERS OF VIDEO CONFERENCING
Today, there is no longer an industry that is not using video conferencing. People from a wide
variety of business entities, academic institutions, healthcare organizations, and government
Page 4 of 12
5. Video Conferencing Today: it’s NOT your Father’s Video Experience
bodies have benefited from video conferencing and collaboration. Regardless of size or
location, today’s video conferencing and collaboration technologies are within reach of any
organization. Video conferencing is no longer confined to executive boardrooms. Video
conferencing has seen significant changes with technology available from the desktop, (at very
attractive prices), to high end communications (with the advent of high definition and
improvements in telepresence) that make meetings truly “like being there”. Improvements in
audio and video quality, display devices, camera designs and user interfaces have made the
experiences users had only a few years ago (i.e. jerky video, dropped calls, poor sound and
images) a thing of the past. Now users can select a wide range of video conferencing
technologies to meet any communication need, including the ability to hold video conferences
on mobile devices.
Also, video conferencing is no longer confined to the office environment. Price reductions and
improvements in connectivity make video conferencing available to any conference room,
desktop, or home office.
APPLICATIONS
Healthcare
Mansfield Health Education Center, Montana
Tom Brewer is the Director of operations for the Mansfield Health Education Center, which is
managed by the Northwest Research & Education Institute (NWREI) in the state of Montana,
and is a joint venture of St. Vincent Healthcare and Rocky Mountain Health Network. Mansfield
Center facilitates clinical and applied research, providing continuing medical education for
physicians and other healthcare professionals, and coordinates community health education
programs. The Mansfield Center is an eight-room facility that includes a room with integrated
video conferencing at the touch of a button to accommodate up to 240 people. This room
enables “town hall” video conferences during which 30 to 50 video-equipped sites are
connected in a single call. The town hall format frequently covers state and local government
healthcare policy issues.
Brewer Stated, “From one end of our video network to the other is about a seven-hour drive; so the
importance of eliminating that distance and seeing patients immediately and in real time cannot be
emphasized enough.”
University of Vermont College of Medicine & Fletcher Allen Health Care
Patients in rural America suffering a severe trauma accident are twice as likely to die as trauma
patients in urban areas. Because of this alarming statistic, the University of Vermont (UVM),
College of Medicine and Fletcher Allen Health Care has a teletrauma program to link rural
hospitals and leverage a 24-hour operator service to help people obtain teletrauma
consultations. The operator contacts the trauma doctor on call, who responds by connecting to
Page 5 of 12
6. Video Conferencing Today: it’s NOT your Father’s Video Experience
the rural hospital using video conferencing. Michael Caputo, Director of Information Systems
and Telemedicine Operations at UVM College of Medicine states, “Polycom units easily mount
on a ceiling or wall and provide the reliability and robustness we need.” In the hospitals, video
units are mounted above patient beds on the wall to give a birds-eye view of the room.
Trauma doctors can then zoom in and out, gaining access to the entire room.
Education
Waterloo University, Canada
Waterloo has long been recognized as the most innovative university in Canada. Like other
universities, Waterloo is committed to advancing learning and knowledge through teaching,
research, and scholarship. One of Waterloo’s researchers who is garnering a lot of attention is
Associate Professor of Drama and Theatre Studies, Gerd Hauck. Hauck has become interested
in theatre and the new media, specifically using video conferencing as a medium for creating
collaborative theatre. “I truly believe that multipoint video conferencing collaborative theatre
has the potential to transform the outcomes of creative processes and, ultimately, to expose
actors, audiences, creative directors, and students to a far broader range of experiences,
perspectives, and voices within the context of theatre production and performance,” explains
Hauck. He adds, “By broadcasting over video, it’s conceivable that one day you could do
Hamlet and have an audience of 10,000 or more people.
Government
North Dakota
Connecting businesses, residents and government agencies over the often remote and sparsely
populated 70,665 square miles of North Dakota is no small task, especially in the harsh winter
months that commonly make rural travel difficult and downright dangerous. These were chief
concerns for the 1999 legislative session and are largely responsible for the creation of the
North Dakota Statewide Technology Access for Government and Education network
(STAGEnet). STAGEnet provides broadband connectivity, Internet access, video conferencing
and other networking services in North Dakota for all state agencies, colleges and universities,
local government, and K-12 schools. Jerry Rostad is the Director of the North Dakota
Interactive Video Network (IVN). He states, “In six months time we supported just short of
20,000 hours of video conferencing activity including 15,041 class sessions and 1,352 meetings.
On average, we facilitate more than 3,000 hours of conferencing each month. And keep in
mind, these numbers don’t even include a significant percentage of the video conferences on
the network which are routinely initiated on a local system without the help of my staff.”
Virginia Supreme Court
Virginia is one of a handful of states in the nation that employs judicial officers – magistrates –
to issue a warrant for every arrest that’s made. While this system provides an additional source
of checks and balances and speeds the process for the accused, it can also put a strain on law
Page 6 of 12
7. Video Conferencing Today: it’s NOT your Father’s Video Experience
enforcement resources. “Video conferencing was an ideal way to cut down on travel time for
our police officers and sheriffs by allowing them remote access to magistrates. But we still
faced the issue of printing an original warrant with a signature at the remote location,” explains
Bob Kelley, applications engineer for the Magistrate Team with the Virginia Supreme Court.
“We came up with the idea of using the data port on a video conferencing system to accomplish
that, but we needed help, so we went to Polycom to see what they could do for us. Together
we came up with a remote print feature that lets a magistrate print a signed warrant at the
officer’s remote site.”
Enterprises
Owens-Illinois
Owens-Illinois is the world’s leading manufacturer of glass and plastics packaging
products, and with more than 140 locations around the globe and 34,000 employees, its
communications needs are complex. That’s why the company implemented video
conferencing in 1996.
Recently, Altajir Glass in the United Arab Emirates contracted Owens-Illinois to design a
glass plant. In the middle of the project, the tensions in Iraq began and Owens-Illinois
was able to use video conferencing for project review meetings instead of traveling to the
Middle East. “Video conferencing gave us the ability to continue conducting business even
in a time of chaos and unrest,” says Dianne Stroshine, multimedia specialist for Owens-
Illinois. “And given the uncertainty of the world, this makes video conferencing more
important than ever for the company.”
Owens-Illinois uses video to communicate with its affiliates and licensees in the Asia
Pacific region, France, Germany, Italy, Poland, Portugal, Spain, the U.K., Mexico, Brazil,
Colombia, Peru, South Africa and the United Arab Emirates.
Adobe Systems
With annual revenues exceeding $1.6 billion, Adobe Systems is one of the world's largest
software companies. And the mission that has helped make Adobe so successful – helping
people communicate better – starts internally. But, in a company with nearly 4000 employees
located around the world, facilitating seamless communication can be a challenge. That's why
Adobe deployed Polycom's complete end-to-end solutions for integrated voice, video and data

TECHNOLOGY COMPONENTS
Video conferencing systems include video cameras, microphones, display screens or monitors,
and processing technology to create virtual meetings between geographically dispersed
participants. Conferences involve the ability to see and hear other participants, as well as share
data, presentations, and anything else – prototypes, scale models, samples – that is brought to
the meeting. Video conferences can be conducted either point-to-point, meaning two locations
are connected in the call, or multipoint, meaning more than two sites are on the call at one
time.
Today’s growth in conferencing and collaboration is real and sustained, with more people in the
U.S. now meeting electronically than in person. Research has confirmed that unrelenting
market pressures, combined with security concerns, have jolted people into reassessing the role
of conventional in-person meetings. This has resulted in a strong upsurge in usage of all the
collaborative applications – voice, data/web and video conferencing. In the past 5 years there
has been an 800% increase in the number of virtual workers and 90% of employees work
somewhere other than the headquarters site. Per Gartner Group, “By year-end 2007,
supporting and encouraging collaboration as part of a high-performance workplace will become
one of the top five CIO priorities.”
Several factors are promoting this accelerating trend
Evolution
Technology is changing the way people hold and share information. While seeing and hearing
people are key elements of human interaction, and thus of video conferencing, one of the most
significant advances in group video systems is the ability to share data. Now everyone can view
and work off the same presentation, spreadsheet, or any other image or document, while still
being able to see all participants in the video call.
The popularity of collaboration reflects the degree to which knowledge workers and managers
have moved from paper and filing cabinets to electronic documents and data storage.
Revolution: More Cost Efficiency
The rapid development of information technology has not only changed the way information is
stored and processed, it has also significantly lowered the costs and improved the effectiveness
of video conferencing technology. Since 1998, the prices of video conferencing endpoints have
dropped ten-fold.
Cost, picture and sound quality, and ease of use have all greatly improved as a result of
development work and increasingly powerful, lower cost technology. Just as important, the
emergence of IP (Internet Protocol) as the pervasive network technology for local area

networks (LANs), wide are networks (WANs), and the public Internet promises standard
connectivity, making it easier to set up conferences on an as-needed, cost-efficient basis.
Revolution: Dramatically Changed Environments
With technical hurdles to video conferencing mostly overcome, psychological and organizational
barriers to adoption and use are now falling fast, as well. Video conferencing is no longer seen
as just a cheap alternative to travel.
Organizations understand that it can also help them address issues such as the dispersion of
global teams, the need to make decisions and implement them within ever-shorter time frames,
and the need to respond more quickly to intense competitive pressure. In addition, as cost,
environmental, and security concerns heighten, video conferencing is also being seen as a more
responsible option from a variety of perspectives, including:
• With the global business slowdown, prudent organizations are acting to reduce their
costs.
• Environmental concerns are increasing the pressure on organizations to adopt green
policies, including optimization of business travel which, it can be argued, contributes to
global warming.
• Security and health concerns mean that organizations must be concerned about the well
being of their employees. This increasingly means curtailing travel to certain
destinations at certain times.
Not surprisingly, many organizations are promoting video conferencing as an alternative to air
travel. Some companies already require employees to confirm on travel requisition forms that
video conferencing is not an option for a specific trip.
IP TO EVERYWHERE
Due to advances in network management and prioritization capabilities, converged IP networks
are becoming the norm for voice, data, and video communications. The growth of broadband
connection to the Internet has resulted in applications such as Web casting – live, audio and
video conferences being set up for everything from company financial results discussions to
corporate seminars – to become highly popular. Hosting video conferencing traffic on the
corporate LAN or WAN simplifies system deployment and management, as well as results in
lower overall cost of ownership for conferencing technologies.
This IP network deployment has provided an alternative to ISDN connections for video
conferencing and will result in the eventual replacement of ISDN as the network transport for
video. Beyond becoming the standard corporate data networking protocol, IP has also become
the network layer protocol that is often deployed with broadband access services using DSL,
broadband wireless, or optical fiber.

Advantages
IP connectivity offers many advantages, including the fact that there is continued development
of the network with increased functionality. Also, IP networks are being proliferated globally.
Many organizations also like the fact that there are no toll charges with IP calls, like there are
with ISDN calls. Finally, with IP networks there continue to be development of add-ons like
chat, directory services, etc.
The ability to integrate video conferencing into PC platforms and use standard data networks to
make connections between conferencing systems is very powerful. This enables video
conferencing applications to scale with the growing corporate, public, and IP managed
networks, while sharing the economies of converged voice, data, and video.
Disadvantages
There are, however, disadvantages to IP networks which need to be overcome. For the most
part, the advantages of an IP end-to-end network do not extend outside private networks.
When traffic flows between organizations on different networks the bandwidth is not always
enough to ensure adequate performance. IP networks were not originally designed to handle
time-sensitive traffic like video conferencing. That is because IP transmits data using a
‘connection-less’ approach, with packets contending as they progress through the network. At
congested links, packets are queued. If the queue grows too long, the packets are sometimes
dropped, prompting the end system to request retransmission. With video conferencing, one-
way packet delay of more than 150 milliseconds, jitter (uneven arrival of data), or dropped
packets can badly compromise performance and cause periods of screen freeze, a change in
the appearance of artifacts (such as blank rectangles), or contribute to poor audio quality and
synchronization problems.
The Solution
Quality of Service (QoS) is the mechanism used to insure that the packets associated with video
conferencing make it through the network in a timely manner, without getting lost, and with no
help from the transport protocol. Queues are the primary contributors to packet loss and delay
in ta packet network. The network must have a QoS mechanism that operates at each switch
and router to prioritize real-time traffic. To gain the maximum benefit, QoS must work from
end-to-end. All routers and switches between the real-time sender and the real-time receiver
must have a QoS mechanism available and enabled. Currently, standards bodies are working
on the development of a QoS scheme to create consistency between vendors to eventually
allow quality of service to be across multiple providers while maintaining similar forwarding
behavior through each.
Bandwidth use is an integral part of QoS. Sufficient bandwidth must be in place on each link to
carry the expected real-time traffic. It is important to analyze expected demand so that proper
bandwidth planning can be done to support video conferencing on the network links. Once the
bandwidth demand has been calculated, an evaluation of existing network bandwidth and
utilization is required to determine if there are sufficient resources to support the new real-time
Page 10 of 12
11. Video Conferencing Today: it’s NOT your Father’s Video Experience
load. Each link of the network needs to have sufficient bandwidth to support the voice and
data traffic expected, plus the existing data applications that use those same connections.
Although this sounds like a daunting task, in practice it usually means evaluating the wide area
network links, the backbone connections to the bridge, and client connections where there may
be 10 Mbps Ethernet or shared Ethernet connections.
