Electrons always travel the path of least
resistance� Any student in an EE class can tell you that and so can any
writer who decided to see what would happen if he stuck a wire into both
sides of an electric socket at age 10. If only there were a way to make IP
packets travel via the path of least congestion, VoIP quality would be so
much better. This of course is the holy grail of VoIP. Remember, there is
no need to limit bandwidth of a VoIP call� 3-D stereo VoIP calls and
even 7.1 surround sound quality calls can be transmitted using today�s
technology. The issue is bandwidth. How much bandwidth do you have and how
do you manage it effectively enough so that your traffic can be
prioritized, allowing voice and video calls to be latency and jitter free?
If only there were a way to achieve what I have
discussed above. Well, of course, I wouldn�t set up a scenario like this
if I didn�t offer a good solution. A company called Virtela
has come up with a way to help corporations solve bandwidth issues on a
global scale. The company doesn�t own a network; think of them as an
aggregator of Tier One bandwidth. They lease the bandwidth and have come
up with ways of routing packets on the least congested route, allowing for
the least latency and the highest availability.
Management of this network is done via NOCs in
CO, where VoIP load balancing and call center apps are managed. Video is
another application where they are seeing increased demand. The goal of
the company is to allow you to reliably transport traffic over IP. Aside
from VoIP and video services, there is also VPN, security and a
do-it-yourself tool kit.
You wouldn�t play with electricity, would you? Of course not. So why
play with IP packets when there are others who will handle this task for
you, allowing you to concentrate on other more important corporate issues?
