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.
What is Ethernet over Copper
Ethernet over Copper, or EoC, uses copper transmission lines rather
that fiber optics. T1 lines are most often used to transport mid-band
Ethernet signals in the 1 to 10 Mbps bandwidth range when provisioning
fiber optic lines is too expensive.
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
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
Will Carriers "Light Buildings"?
Some will if their closest point of presence (POP) is within a
mile or so of your location. The farther away you are, the higher
the bandwidth commitment needs to be in order to justify the carrier's
