The NetVanta® 3140 is a fixed-port, high-performance Ethernet router supporting converged access and high-quality voice services. It provides three routed, autosensing Gigabit Ethernet interfaces. This product is ideal for carrier-bundled service offerings, and enterprise class Internet access for secure, high-speed corporate connectivity. The NetVanta 3140 is available as either a desktop, or rack mountable platform.
Flexibility and Redundancy
The NetVanta 3140 is ideal for multiple applications where Ethernet redundancy is needed given the three Gigabit ports that can be either LAN or WAN facing. This can be achieved with two Ethernet delivered access services providing immediate failover to the active link anytime a link down event occurs. In addition, the NetVanta 3140 features USB interface that can be used for 3G/4G backup.
Many deployments still feature separate voice and data networks, and the NetVanta 3140 is a perfect fit for these as well with a single WAN link, the other two Gigabit interfaces can accomplish this.
The versatile hardware platform of the NetVanta 3140 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. Multihoming is also available to provide redundant or backup WAN links to multiple ISPs, guaranteeing a widearea connection.
QoS is also supported for delay-sensitive traffic like VoIP or video. To prioritize mission-critical traffic and control network congestion, the NetVanta 3140 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.
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 3140 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.
