The Cisco 3600 Series Multiservice Solution For Branch Offices
The Internet has opened new vistas for exploration,
exchanging ideas, and commerce. What’s more, Web
browser-based interfaces simplify Internet and intranet
applications—making them so easy to use that many
companies now depend upon the network to conduct
mission-critical business activities. This browser simplicity
drives the adoption of the globally networked business
model, which selectively provides secure services and
resources to anyone, anywhere, any time via the World
Wide Web. Everyone in a globally networked business
needs access to vital central resources.
BRANCH OFFICE COMPUTING REQUIREMENTS
Branch offices, once autonomous from main offices, now
need to connect to centralized hosts and servers, so users can
communicatewitheachother,theircustomers,suppliers,and
partners. The ongoing trend toward faster, more capable
desktopcomputing withever more powerfulmultimedia and
mission-critical applications drives demand for expanding
network infrastructures to support them. It falls to the
network administrator to meet this user demand.
As bandwidth requirements increase and network
services must support advanced applications, it is clear that
today’s multiple-device branch office solutions, while
adequate for today’s requirements, become difficult to
manage and expensive as needs change over time. Because
specialized devices offer few options for expansion, today’s
multiple-devicesolutionsusuallyrequireaforkliftupgradeto
meet tomorrow’s demand for new services.
THE MULTISERVICE DEVICE SOLUTION FOR
BRANCH OFFICES
The alternative to the unwieldy, often expensive multiple-
device solution is consolidation of network services into a
single multiservice device. Such a solution would be much
easier to set up and manage—but must also be absolutely
reliable. It must demonstrate the horsepower to handle a
variety of activities at wire-speed performance while having
extreme flexibility in connectivity, bandwidth, and local
network services such as security and multimedia
application support—and do everything at a lower cost
than today’s solutions. An office so empowered becomes a
next generation branch office, ready to take on the
advanced computing challenges of rapidly growing Internet
and Intranet applications.
Today’s sophisticated users require dial access,
advanced LAN-to-LAN routing services for networked
multimedia applications, legacy traffic support, and
multiservice consolidation of anticipated future
technologies such as digital subscriber lines (xDSL), and
integrated voice, video, and data networks. Until now,
administratorshavehadtopurchase at least threedevices to
meet all these needs. The Cisco 3600 series combines all
three capabilities into a single platform.
