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.
What is PBT?
PBT stands for Provider Backbone Transport. It's an adaption of
Ethernet to extend Layer-2 switching into the WAN transport network.
PBT was pioneered by Nortel and will be standardized by the IEEE
What is QoS and how do you
QoS means Quality of Service. Most often you hear about QoS when
referring to converged networks that transport both packet voice
and data. QoS mechanisms may include prioritizing voice packets
over data because voice is much more affected by latency and jitter.
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
