ADTRAN NetVanta 5305
Multi-slot Access Router Supporting up to Two T3's of Bandwidth

Overview:

The NetVanta^® 5305 is an access router designed for cost-effective Internet access, corporate Frame Relay, point-to-point connectivity, and VPN for large-bandwidth applications supporting T3 networks.

Modular Hardware

Residing in a 3U high, 19" rackmountable metal enclosure, the NetVanta 5305 is a single platform that offers six interface slots and dual 10/100Base-T Ethernet LAN ports for true LAN segmentation or DMZ applications. A single slot within the NetVanta 5305 will house an Unchannelized T3, Octal T1/E1, or HSSI Wide Module.

Standards Protocols

The versatile hardware platform of the NetVanta 5305 is further complemented by the AOS. The AOS allows for the support of static and default routes, demand and policybased routing, and allows for fast, accurate network convergence using routing protocols such as BGP, OSPF, RIP, and PIM Sparce Mode for multicast routing. 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 5305 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.

The NetVanta 5305 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

For added security, the AOS provides a powerful, high-performance stateful inspection firewall. 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.

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 5305 also adds the support for IPSec-compliant VPN. The NetVanta 5305 supports up to 2,000 simultaneous VPN tunnels, while also supporting encryption algorithms like DES, 3DES, and AES. With this upgrade, the NetVanta 5305 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 stepby- step configuration wizards.
