Medical Imaging Transmission
Medical images, such as those generated by Teleradiology equipment,
have large file sizes due to high resolution. Rapid transmission
between hospitals and medical centers requires high availability,
high bandwidth telecommunication services. For smaller offices
or infrequent use, a T1 data line might easily suffice. For medium
and larger facilities, DS3 or Ethernet fiber optic carriers are
recommended.
What does Convergence mean?
Convergence is the merging of voice, data and often video onto
a single network. Most often that network is a company LAN with
enough bandwidth to accommodate all users and QoS or Quality of
Service control to ensure high quality voice and video transmissions.
Where does a VPN make sense?
A VPN or Virtual Private Network is a security technique to allow
public networks, like the Internet, to be used for secure private
data transmission. Since Internet access is almost universally
available, using VPN software to encrypt data into private tunnels
is more cost effective than building a fully meshed network to
connect many locations.
How does Spanning Tree Protocol
work?
STP or Spanning Tree Protocol is a technique used by Ethernet
switches to ensure that there is one and only one physical path
from source to destination. This is done to prevent forwarding
loops.
What is the Cost Advantage
of Carrier Ethernet
Where available, Ethernet transport services from competitive
carriers may cost less than half the lease price of DS3 service
for over twice the bandwidth. The difference in cost between SONET
optical carrier service and Gigabit Ethernet WAN service is even
more dramatic.
