Sharing Business Broadband
Costs
Even smaller businesses can have high performance dedicated Internet
access by splitting the cost of a fiber optic Ethernet connection
with other businesses in their building or business park.
Carrier Ethernet is Available
Now
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
as PBB-TE.
How does Spanning Tree Protocol
work?
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
loops.
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
construction costs.
