So you have worked on Cisco routers and switches for a while and now want to get your
CCIE? There are several good reasons to do so. Cisco’s certification program allows network
analysts and engineers to demonstrate competence in different areas and levels of
internetworking. Cisco certification can help you land a job or increase your pay because
clients, peers, and superiors recognize you as a networking expert. CCIE certification is
regarded as the most difficult and rewarding of the internetworking industry.
For years now, data networks have become increasingly important. At first,
networks were just a large corporate phenomenon. Now, almost any business
with more than a few computers or more than one location has a data network.
And now, with the growth of the Internet, many people’s home computers
are often connected to a network. As data networks grow in size and
importance, there must be a corresponding growth of people required to
design, build, and maintain them.
A major U.S. regional carrier needs to create a high-speed data network
using its existing voice infrastructure in more than 300 metropolitan and
rural markets. Without this service upgrade, the carrier stands to lose
significant high-value business and residential customers to new
providers of high-speed services in many of its key markets.
Design and deploy a DSLAM solution rapidly and efficiently while
maintaining the highest standards of quality with each deployment.

The traditional role of traf®c engineering is to ensure that a telecommunications network has just enough capacity to meet expected demand with adequate quality of service. A critical requirement is to understand the three-way relationship between demand, capacity, and performance, each of these being quanti®ed in appropriate units. The degree to which this is possible in a future multiservice network remains uncertain, due notably to the inherent self-similarity of traf®c and the modeling dif®culty that this implies.
With customers demanding higher speed Ethernet services at lower price points, carriers are
looking for ways to offer new services while maintaining the current revenue streams from existing
services. In addition, service providers would like to extend the life of current infrastructures and
be able to migrate to the next generation of networks at the appropriate time.
This chapter concentrates on the characteristics and limitations of the different
types of Ethernet, Token Ring, and Fiber Distributed Data Interface (FDDI)
technologies. After reviewing each of these technologies, the chapter briefly turns
to voice and video communications that can be delivered over existing data networks.
These topics are called Multiservice Services by Cisco.
