Traditional
Routing
Traditional routing platforms
pass all traffic through a single
processor. With the increase
in WAN grooming features
required and the need to
increase performance, tradi-
tional architecture does not
scale well. In order to accom-
modate these requirements,
traditional routers would require hardware
upgrades or additional hardware modules;
resulting in increased costs to the customer.

Benefits
Minimal degradation from complex WAN processing tasks.
Customers can optimize their WAN utilization to fit their needs through the use
of Prioritization, Bandwidth Reservation, Bandwidth-on-Demand, and Load
Balancing services.
Range of compression algorithms (packet-based, history-based, and tiny-gram) provides
the ability to maximize the use of the WAN pipe.
Helps system administrators optimize network traffic flow while planning for future
resource requirements.
Significantly reduces the amount of network downtime in the event of failure. The
NETBuilder II router provides the ability to replace an interface module without
disruption to the other modules in the unit.
New interface modules can be inserted into an active NETBuilder II router and can be
automatically recognized without disrupting network activity.
A second PC Card slot is available on the DPE plus module providing flexible storage
capacity, reliable booting, and easy software updates.
Aids in reducing downtime by providing immediate diagnostic evaluations and
automatic memory dumps in the event of a system failure.
Provides redundancy to ensure network availability (available option for NETBuilder II
8-slot and 8-slot extended chassis).
Standards-based solution providing transparent fail-over of default gateway for
LAN-based clients.
Automatic fail-over to a dial-up line in the event of primary line failure.
Allows translation of network IP addresses for usage outside that network.
Controls access and data into and out of the network.
Provides standard-based scalable data security for router-to-router applications.
NETBuilder II DPE Processor
Get Packet
The DPE addresses problems a single processor has
with adding WAN grooming functionality. This archi-
Process Packet
tecture utilizes a dedicated coprocessor to perform the
complex WAN grooming functions, freeing the main
processor to focus on packet processing, which results
WAN Grooming
in increased performance with greater functionality.
