Backbone
Backbone:
direct
connection to
the Internet The simple transfer rate between the network operator and participant does not by itself
determine the speed at which the Internet can be accessed. The network operator must
also forward data destined for the Internet to a backbone. The dimensioning of this
connection ultimately determines the speed at which you can surf. The backbone can
become a bottleneck if a large number of participants want to access Internet data
simultaneously and the network operator does not have an adequately dimensioned
connection to the Internet.
Internet at all times—always online
One of the biggest advantages of cable modem technology is the continuous availability
of the Internet. While “normal” Internet connections need to be established as required,
all cable modem users on a cable section can be permanently registered with the
headend. The multiport capabilities of the remote stations ensure that other participants
are not blocked due to a lack of connections. The advantages of this permanent Internet
connection:

Immediate availability of all information
Your e-mail comes to you directly—not just when you pick it up. To view a Web
page, just open your browser and don't worry about connecting to your provider.

Your own Internet server
Until now, running your own Internet server generally meant having an extremely
expensive leased line to the provider. Now you have one! If you would like to set
up your own Web server for your company, you can now do so and have it accessible
at all times via the cable modem at no additional cost.
More than just Internet
Together with the appropriate remote stations, cable modems form the connection
between network participants (private or business) and the network operator. Very high
throughputs—and thus very fast data transfers—can be realized using such a
connection. In addition to providing fast Internet access, this creates a number of other
interesting options for the evolution of network operators into information service
providers.
Regional content
Cable network operators generally have a local or regional orientation due to the
structure of the cable network. The headends that have to be additionally integrated into
the network with their restriction to around 2000 participants results in further area
limitations.
