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.
NETBuilder II Features and Benefits
Features
Benefits
Performance
DPE Processor
Minimal degradation from complex WAN processing tasks.
Bandwidth Grooming
Customers can optimize their WAN utilization to fit their needs through the use
of Prioritization, Bandwidth Reservation, Bandwidth-on-Demand, and Load
Balancing services.
Compression
Range of compression algorithms (packet-based, history-based, and tiny-gram) provides
the ability to maximize the use of the WAN pipe.
Proactive management tools
Helps system administrators optimize network traffic flow while planning for future
resource requirements.
Network Availability
Serviceability
Hot swap
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.
Hot plug and play
New interface modules can be inserted into an active NETBuilder II router and can be
automatically recognized without disrupting network activity.
Dual flash system
A second PC Card slot is available on the DPE plus module providing flexible storage
capacity, reliable booting, and easy software updates.
Diagnostic support
Aids in reducing downtime by providing immediate diagnostic evaluations and
automatic memory dumps in the event of a system failure.
Reliability
Dual power supply
Provides redundancy to ensure network availability (available option for NETBuilder II
8-slot and 8-slot extended chassis).
Router redundancy
Standards-based solution providing transparent fail-over of default gateway for
LAN-based clients.
Disaster recovery
Automatic fail-over to a dial-up line in the event of primary line failure.
Security Control
Network Address Translation
Allows translation of network IP addresses for usage outside that network.
Built-in Internet Firewall
Controls access and data into and out of the network.
IPsec
Provides standard-based scalable data security for router-to-router applications.

NETBuilder II DPE Processor
The DPE addresses problems a single processor has
with adding WAN grooming functionality. This archi-
tecture utilizes a dedicated coprocessor to perform the
complex WAN grooming functions, freeing the main
processor to focus on packet processing, which results
in increased performance with greater functionality.
