As a multiservice access router, the 
NetVanta®3448 uses RapidRoute 
technology to deliver the high-packet 
throughput required for IP telephony, 
corporate connectivity, and Internet 
access. This performance-enhanced 
platform delivers wire-speed throughput, 
even with advanced services enabled like 
Quality of Service (QoS), NAT, firewall, 
and VPN.
Modular Hardware
The NetVanta 3448 is a modular, 1U-high, 
rackmountable metal chassis that offers a 
single slot to house any of the NetVanta Series 
Network Interface Modules (NIMs) and Dial 
Backup Interface Modules (DIMs). For dial 
backup, an analog modem DIM or an ISDN 
BRI DIM is available, preventing downtime 
by dialing around a failed circuit to any PPP-
compliant device. The NetVanta 3448 also 
includes two 10/100Base-T Ethernet interfaces 
and a fully managed, non-blocking, eight-port 
switch which can be separately powered 
to yield an 802.3af-compliant PoE switch 
delivering a full 15.4 watts per port.
Standards Protocols
Complementing the versatile hardware, 
the AOS allows for the support of standards-
based switching, Virtual LAN (VLAN) tagging, 
static and default routes, and demand routing. 
This enables fast, accurate network conver-
gence using routing protocols such as BGP, 
OSPF, and RIP. In addition, the AOS terminates 
MPLS, Frame Relay, Multilink Frame Relay, 
PPP, Multilink PPP, 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 3448 uses Low Latency Queuing, 
Weighted Fair Queuing (WFQ), Class-based 
WFQ, and DiffServ marking to establish the 
priority of IP packets routed over the WAN. 
VoIP Ready
In combination with the QoS features, a 
specialized SIP ALG allows SIP traffic to 
traverse NAT-enabled firewalls. For enterprise 
networks, this interoperability allows IP PBXs, 
phones, and other SIP-based devices to set 
up, tear down, and pass voice and call control 
messages seamlessly through the integral 
NAT-enabled firewall. 
The NetVanta 3448 also deploys VQM to 
capture MOS, jitter, delay, and packet loss 
statistics necessary to troubleshoot VoIP calls 
over the WAN. This powerful, yet graphically 
intuitive, diagnostic tool allows for quick 
isolation of network issues to ensure superior 
call quality.
Security
The AOS provides a powerful, high perfor-
mance stateful inspection firewall that can 
identify and protect against common Denial 
of Service (DoS) attacks like TCP syn flooding, 
IP spoofing, ICMP redirect, ping of death, and 
IP reassembly problems. 
In addition, the AOS is capable of providing 
an inherent URL-filtering package without 
the use of an external server. URL filtering is 
another level of security that allows system 
administrators to restrict Internet access by 
permitting or denying specific URLs. This 
URL-filtering feature also includes the ability 
to produce top website reports of the most 
frequently requested websites, allowing 
system administrators to modify the URL 
filter lists.
The NetVanta 3448 also supports up to 500 
simultaneous IPSec VPN tunnels and encryp-
tion algorithms like DES, 3DES, and AES. By 
supporting IPSec, the NetVanta 3448 is fully 
compatible with other IPSec VPN-equipped 
NetVanta products.
Administration
The AOS offers both a CLI that mimics the 
widely deployed industry de facto standard 
and an intuitive Web-based GUI with step- 
by-step configuration wizards.
