Designing Wans

WAN communication occurs between geographically separated areas. In enterprise internetworks,
WANs connect campuses together. When a local end station wants to communicate with a remote
end station (an end station located at a different site), information must be sent over one or more
WAN links. Routers within enterprise internetworks represent the LAN/WAN junction points of an
internetwork. These routers determine the most appropriate path through the internetwork for the
required data streams.
WAN links are connected by switches, which are devices that relay information through the WAN
and dictate the service provided by theWAN.WAN communication is often called a service because
the network provider often charges users for the services provided by theWAN (called tariffs).WAN
services are provided through the following three primary switching technologies:
LAN Technology Typical Uses
Routing technologies Routing is a key technology for connecting LANs in a campus network. It can be
either Layer 3 switching or more traditional routing with Layer ...
... 3 switching and
additional router features.
Gigabit Ethernet Gigabit Ethernet builds on top of the Ethernet protocol, but increases speed ten-fold
over Fast Ethernet to 1000 Mbps, or 1 Gbps. Gigabit Ethernet provides high
bandwidth capacity for backbone designs while providing backward compatibility for
installed media.
LAN switching technologies
Ethernet switching
Token Ring switching
Ethernet switching provides Layer 2 switching, and offers dedicated Ethernet
segments for each connection. This is the base fabric of the network.
Token Ring switching offers the same functionality as Ethernet switching, but uses
Token Ring technology. You can use a Token Ring switch as either a transparent
bridge or as a source-route bridge.
ATM switching technologies ATM switching offers high-speed switching technology for voice, video, and data. Its
operation is similar to LAN switching technologies for data operations. ATM,
however, offers high bandwidth capacity. Introduction 1-5
Trends in WAN Design
Circuit switching
Packet switching
Cell switching
Each switching technique has advantages and disadvantages. For example, circuit-switched
networks offer users dedicated bandwidth that cannot be infringed upon by other users. In contrast,
packet-switched networks have traditionally offered more ?exibility and used network bandwidth
more ef?ciently than circuit-switched networks. Cell switching, however, combines some aspects of
circuit and packet switching to produce networks with low latency and high throughput. Cell
switching is rapidly gaining in popularity. ATM is currently the most prominent cell-switched
technology. For more information on switching technology for WANs and LANs, see Chapter 2,
Internetworking Design Basics.
