Multi-slot Access Router Supporting Multiple E1s and Carrier Ethernet

The NetVanta 4430 is an access router designed for higher-bandwidth applications supporting up to eight T1s for Internet access,corporate Frame Relay, point-to- point connectivity, ADSL, VPN, and up to carrier Ethernet connections.

Modular Hardware
Residing in a 1U high, 19" rackmountable metal enclosure, the NetVanta 4430 is a single platform that offers one wide module slot, two Network Interface Module (NIM) slots, dual Gigabit Ethernet LAN ports (copper or fiber) for true LAN segmentation or DMZ applica-tions, and one 10/100Base-T Fast Ethernet port for management or routing. The single wide module slot within the NetVanta 4430 will house the Octal T1/E1 Wide Module, while the NIM slots will support a variety of the NetVanta NIMs and Dial Backup Modules (DIMs).

Standards Protocols
The versatile hardware platform of the NetVanta 4430 is further complemented with the AOS. The AOS allows for the support of static and default routes, demand and policy-based routing, and allows for fast, accurate network convergence using routing protocols such as BGP, OSPF, RIP, and PIM Sparse Mode for multicast routing. In addi- tion, the AOS terminates MPLS, Frame Relay, Multilink Frame Relay, PPP, Multilink PPP, PPPoE, PPPoA, RFC 1483, and HDLC Wide Area Network (WAN) protocols. Multihoming is also available to provide redundant or backup WAN links to multiple ISPs, guaranteeing a wide-area connection.

QoS
QoS is also supported for delay-sensitive traffic like VoIP or video. To prioritize mission-critical traffic and control network congestion, the NetVanta 4430 uses Low Latency Queuing, Weighted Fair Queuing (WFQ), Class-based WFQ, and DiffServ marking to establish priority of IP packets routed over the WAN. The NetVanta 4430 also includes Enhanced QoS support for Ethernet WAN connections including the ability to prioritize traffic by VLAN.
