NETBuilder II Features and Benefits Features Performance DPE Processor Bandwidth Grooming Compression Proactive management tools Network Availability Serviceability Hot swap Hot plug and play Dual flash system Diagnostic support Reliability Dual power supply Router redundancy Disaster recovery Security Control Network Address Translation Built-in Internet Firewall IPsec 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. Traditional Routing Get Packet Traditional routing platforms pass all traffic through a single Process Packet processor. With the increase in WAN grooming features required and the need to WAN Grooming increase performance, tradi- tional architecture does not scale well. In order to accom- Send Packet modate these requirements, traditional routers would require hardware upgrades or additional hardware modules; resulting in increased costs to the customer. 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 psearfmoprmleannectewwoirtkhdgiraegartaemr functionality.
