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.
How is PoE used for IP Phones?
PoE or Power over Ethernet is a standard that defines a way to
transmit electric power to network devices as well as information
packets. When PoE equipment is installed in equipment lockers,
an IP telephone gets its power from the network and does not need
a separate AC power supply.
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.
How does Spanning Tree Protocol
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
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
