REQUIREMENTS OF A ROBUST BRANCH OFFICE

NETWORK SOLUTION

When Cisco Systems looked at this emerging networking

market, it became clear that a reliable, long-lived branch

office solution must contain seven elements:

• Platform modularity and ﬂexibility—Supports any WAN

service such as leased lines, Integrated Services Digital

Network (ISDN), Frame Relay, X.25, Switched 56 and

Switched Multimegabit Data Service (SMDS), and

emerging services such as xDSL and Asynchronous

Transfer Mode (ATM)

• End-to-end security and data privacy—Ensures support of

corporate security policies in branch ofﬁces

• End-to-endqualityofserviceguarantees—Supportscurrent

and future multimedia, multicast, voice integration, and

other time-sensitive applications

• Enhanced Internet/Intranet access features—Reduces cost

and increases ﬂexibility in protocol or address

management, including Dial Virtual Private Networks

(Dial VPNs)

• Easy to set up and use—Keeps deployment costs at

a minimum

• WAN optimization features—Ensures best use of available

bandwidth to reduce recurring WAN line costs, including

data compression

• Centrally manageable—Lowers operations costs with

remote management capabilities

SHIFTING TO A SINGLE-DEVICE SOLUTION:

WHAT YOUR NETWORK NEEDS

Particular requirements of a branch ofﬁce vary widely.

Cisco sees three primary usage areas: dial access, routing or

LAN-to-LAN services and, more recently, multiservice

integration of voice, video, and data on the same

infrastructure. Until now, network managers have viewed

these as separate requirements and met them with at least

three devices. Shifting all branch ofﬁce network functions to

one device requires a reality check. A single-device solution

must meet the challenge. Consequently, network managers

seek solutions for the branch ofﬁce that provide high

performance, ﬂexibility, and are cost effective.

High Performance

Platformperformance is ofprimaryconcern when considering

the networking requirementsof abranch office in moredetail.

If an office shifts all of its activity from several devices to a

single Multiservice device, the new solution must be up to the

challenge of simultaneously directing activities like Internet

access, LAN switching, dial access, WAN access to a

mainframe,and dial-out faxing—all atfullwirespeed,withno

retransmission or dropped traffic. The device should also

provide advanced Layer 3 services such as security,

manageability, and multimedia and voice application support.

Flexibility

Along with these new application possibilities, wide-area

networkingoptionsfordelivering network servicestobranch

ofﬁces also present challenges as network administrators

seek to meet today’s needs, yet must prepare for future

change. For instance, a branch ofﬁce using ISDN to connect

to the main ofﬁcemay require a high-speed, dedicatedFrame

Relay service in a year’s time due to increased trafﬁc on the

network—and would like to make the upgrade without

bringing a forklift to the wiring closet.

Cost Effective Solutions

Compare the cost of today’s multiple device solutions to a

single multiservice device. Theinstallation cost of a multiple-

device solution is in itself daunting. Add in the extra expense

of separate WAN connections for each one—none of which

are fully utilized—and multiple devices become quite

expensive when compared to a single multiservice device.

The Cisco 3600 single-device solution not only saves

you an average of at least 50% the ﬁrst year, when compared

to a multiple-device solution, it protects your investment as

well. As connectivity and service needs change, it’s easy to

change conﬁgurations with a simple swap of a network

module. This design feature helps you respond quickly to

changing service demands with minimal disruption of

network service and at a much lower cost than replacing an

entire unit.

The savings don’t stop there. A Cisco 3600 solution

saves management and operations costs, conserves rack

space, and eliminates the cable management difﬁculties of

multivendor, multi-device solutions.
