Introduction
• Telecommunication networks and services are the
backbone of the emerging information society
 Most innovation depend on the easy access provided by telecom
operators
• The past few years, have seen the emergence of
new technologies
 Internet, optical fiber, satellite communication

Introduction
• Traffic and number of users are increasing, and new
applications are coming.
• New service providers entering into the marketplace are
challenging the established service providers and
threatening even the core business of traditional public
network operators (PNOs) as they emphasise meeting
customers’ needs as the key to success and survival.

Introduction
• Access network is the
infrastructure between
the customer premises
and the nearest local
exchange (LEX), point
of presence (POP) or
cable hub.
• Access network is often
called the last mile or
local loop

Telecom
Access Network
BBN810S
Example of Access Networks
• Twisted pair
networks, built for
telephone services
• Cable networks,
intended for
broadcast service
• Cellular radio for
mobile networks
• Satellite for
broadcast

Introduction
• Interactive broadband services are now emerging and none
of the mentioned access technology have the capacity to
provide interaction broadband without a network upgrade
• Access networks providers need to prepare their
technology to the interaction broadband services
• The access technology is the most cost sensitive part of the
telecom networks and the one closely related to service
demands

Challenge
• Develop the existing network infrastructure
into a broadband network, i.e, high speed
network.

High Speed Networking:
A Layered View
• Faster media/Link does not necessarily
imply faster network applications
• Interdependence between layers
• Interactions between protocols
• Need to consider trends of all layers
