Advantage of Colocation Bandwidth
Colocation is locating your servers in a colocation facility,
also known as a carrier hotel. Advantages of this approach include
ready availability of low cost bandwidth including 10 Mbps Ethernet,
100 Mbps Fast Ethernet, and Gigabit Ethernet options. These data
centers also offer backup power, environmental control and high
levels of security.
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
Duplex system?
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 QoS and how do you
get it?
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 Mid-Band Ethernet?
Mid-Band Ethernet is a WAN or Wide Area Network technology that
delivers 2 to 45 Mbps over existing copper pair wiring. This bandwidth
range falls neatly in between T1 lines at 1.5 Mbps and DS3 service,
usually provided over fiber optic carriers, at 45 Mbps. As a native
Ethernet delivery system, mid-band Ethernet offers an easy way
to extend the corporate network beyond the premises.
