Question

Suppose an organisation has 20 employees who work, on average 8 hours each day, and during the busy hours (approximately 10-11 and 14.00-15.00), they are engaged in video-conferencing 20% of their time with clients of the organisation (as part of the normal operation of the company). Estimate the video-conferencing traffic in Erlangs. Choose an encoding rate, in bits/s, which will be used for the audio and for the video, for these sessions, and estimate, from this, the mean and standard deviation of the required bit rate for this traffic. From this, estimate the capacity which would be required on a link dedicated for this traffic.

Explanation / Answer

Web Conferencing Saves Time
Without having to travel, employees can spend their working hours being productive, meaning that more
work will get done in less time than before. This is a huge deal nowadays, when executives and clients
alike are increasingly demanding, and results are expected fast. Web conferencing helps improve
employee efficiency, the technology that powers it makes it possible for workers to get
in touch with people all over the world almost instantly. web conferences can be done
in as little as 30 minutes, so employees don't spend time in lengthy but mostly useless meetings
just because they have travelled somewhere.Saves MoneyThe price of traveling has increased
significantly in the past few years, whether employees are taking a plane or driving to their destination.

Add to that the cost of meals and accommodation, and companies are left with a hefty bill for a
single employee to attend a meeting. On the other hand, web conferencing can even be free,
as there are many free web conferencing tools available. This is especially important when
the economy is struggling and companies need to save every penny in order to keep their employees.

Enables Employees to Meet at Any Time
Even though workers are might not be face-to-face in an online meeting, they still help with team
building since they can happen more often. In fact, web and video conferencing is so flexible,
that it can happen at any time and from anywhere, as long as those involved have an Internet-enabled device.
Team members can make themselves available to each other at any time,if there's a pressing deadline,
for example, they can work together to meet it. This ability to speak to anyone from the company at
any time, helps dispersed employees feel like they're part of a tight-knit group, improving team
morale and results. Companies can also use web conferencing to communicate with their employees
on a regular basis, creating a sense of transparency within the organization.

Lets Companies Hire the Best Talent, Regardless of Location
Gone are the days when companies could only hire local talent or those willing to relocate.
With the advent of remote working and web conferencing, companies are free to hire talent
from anywhere in the world, since employees can communicate easily and clearly with the
click of a button. Web conferencing has helped remove geographical barriers, as teams
can now be built and monitored remotely with an unprecedented level of communication between employees.

Helps improve Client Relationships
Web conferencing helps companies keep in touch with clients on a more regular basis,
so they can feel involved in the projects they have commissioned. Online meetings can
also be more interactive and interesting than phone calls,it's possible to share slides,
videos and even desktop screens. This means that employees can not only explain the progress
of a project, but they can demonstrate it as well. This helps client relationships become closer and more transparent
