The NetVanta 344 is a business-class ADSL/
ADSL2/ADSL2+ IP access router with an
integral four-port Ethernet switch.
It
provides a single ADSL network interface
and four auto-sensing 10/100Base-T Ethernet
interfaces. This product is ideal for carrier
bundled service offerings and enterprise
Internet access for secure, high-speed
corporate connectivity. In addition to
supporting ADSL (Annex A and B), and
ADSL2, the NetVanta 344 supports today’s
most advanced ADSL technology, ADSL2+,
for applications taking advantage of its
greater reach and higher bandwidth, up
to 25 Mbps. A variety of WAN protocols are
supported including PPP over ATM and
PPPoE over ATM.
Standards Protocols
The versatile hardware platform of the
NetVanta 344 is further complemented
with the ADTRAN Operating System (AOS).
The AOS allows for the support of standards-
based switching, VLAN tagging, static and
default routes, demand routing, and allows
for fast, accurate network convergence using
routing protocols such as BGP, OSPF, and RIP.
Security
The AOS provides a powerful, high perfor-
mance stateful inspection firewall. It will
examine all incoming and outgoing packets
against the security policies established by
the IT manager. In addition, the firewall
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.
With the AOS Enhanced Feature Pack
Upgrade, the NetVanta 344 supports up to
five simultaneous IPSec VPN tunnels, and
encryption algorithms like DES, 3DES, and
AES. With this upgrade, the NetVanta 344
is fully compatible with other IPSec VPN
equipped NetVanta products.
Quality of Service (QoS)
QoS is also supported for delay sensitive
traffic like VoIP or video. To prioritize
mission critical traffic and control
network congestion, the NetVanta 344
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 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.
Administration
The AOS offers a standard Command
Line Interface (CLI) that mimics the
widely adopted, industry
de facto
standard. The sequence of commands
to configure similar devices is almost
identical, virtually eliminating training
costs associated with re-learning a new
operating system or costly industry
certifications. The CLI also allows for
configuration scripts to be used, saved,
and downloaded for a quick and easy
recovery mechanism. In addition, an
intuitive Web-based GUI provides
step-by-step configuration wizards,
management capability, and the ability
to upload firmware updates.
ADTRAN, the leader in WAN connec-
tivity, offers proven and dependable
equipment that will increase your
network performance, lower costs, and
allow migration to next generation
technologies. The NetVanta 344
is no exception.
