The NetVanta 3000 Series of modular
access routers is designed for cost-effec-
tive Internet access, corporate Frame Relay,
point-to-point connectivity, ADSL, and
Virtual Private Networking (VPN). The
NetVanta 3000 Series currently consists
of the NetVanta 3200, 3205, and 3305
with a variety of interchangeable NIMs
and Dial Backup Modules (DIMs).
Modular Hardware
The NetVanta 3305 is a dual-slot, dual-
Ethernet 1U high, rackmountable metal
enclosure. A single slot within any of the
NetVanta 3000 Series will house a variety
of NIMs and DIMs. For dial backup, an
analog modem DIM or an ISDN BRI DIM
is available for preventing downtime by
dialing around a failed circuit to any
PPP-compliant device.
Standards Protocols
The versatile hardware platform of the
NetVanta 3305 is further complemented
with the ADTRAN Operating System (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,
and RIP. In addition, 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 3305 uses Low
Latency Queuing, Weighted Fair Queuing
(WFQ), Class-based WFQ, and DiffServ
marking to establish priority of IP packets
routed over the WAN.
VoIP Ready
In combination with the QoS features,
a specialized Session Initiation Protocol
(SIP) Application Layer Gateway (ALG)
allows SIP traffic to traverse NAT-enabled
firewalls. For an enterprise network, 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.
Security
For added security, AOS provides a
powerful, high-performance 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 3305 also supports
up to 500 simultaneous VPN tunnels,
while supporting encryption algorithms
like DES, 3DES, and AES. By supporting
IPSec, the NetVanta 3305 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.
