Bandwidth to Support Convergence
Convergence means combining or converging voice, data and video
onto a single network. Enterprises usually need to expand their
LAN bandwidth and set up a QoS or Quality of Service priority
system to give priority to real-time streams such as telephone
calls or video conference feeds, which are more sensitive to network
delays than data transfers. Most often, the common protocol for
convergence is IP.
Carrier Ethernet is Available
Carrier Ethernet Services are already available in major metropolitan
areas from competitive carriers such as XO Communications. You
can order 10 Mbps Ethernet, 100 Mbps Fast Ethernet or Gigabit
Ethernet connections to match your current network bandwidth.
Is Ethernet a Full or Half
The original Ethernet implementation was based on avoiding collisions
on packets all sharing the same network line. Small networks using
hubs are half-duplex. Switched Ethernet networks are full duplex
because the layer 2 switches prevent packet collisions.
What is a Service Level Agreement?
An SLA or Service Level Agreement is often part of the contract
between a business and telecom carrier for line services such
as carrier Ethernet.The SLA spells out the expected availability
of the line service and what penalties the carrier is liable for
if the line doesn't perform as stated.
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
