3140 Fixed port secure access ethernet router
Overview:
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 service offerings and enterprise-class internet access for secure, high-speed corporate connectivity. The NetVanta 3140 is available as either a desktop or rack-mount able platform.
Flexibility and redundancy
The NetVanta 3140 is ideal for multiple applications where ethernet redundancy is needed, given the three gigabit ports that can beeither 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. Many deployments still feature separate voice and data networks, and the NetVanta 3140 is a perfect fit. With a single WAN link, the other two gigabit interfaces can accomplish this.
Standards protocols
The versatility of the hardware platform is complemented by the AOS. The AOS allows for the support of static and default routes, demand and policy-based routing and 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 WAN connection.
Hierarchal QoS
QoS is supported for delay-sensitive traffic like VoIP or video. To prioritize mission-critical traffic and control network congestion, theNetVanta 3140 uses low latency queuing, Weighted fair queuing (WFQ), Class-based WFQ, and DiffServ marking to establish thepriority of IP packets routed over the WAN.
VoIP ready
The NetVanta 3140 is VoIP-ready with QoS, Class of service (CoS), Session initiation protocol (SIP) transparent proxy, Net flow 9traffic monitoring, and VQM. traffic monitoring is for collecting and measuring network traffic patterns, while VQM is an intuitive interface that displays captured data for Mean opinion score (MOS), jitter, delay, and packet loss statistics necessary to troubleshoot VoIP calls. This powerful yet graphically intuitive diagnostic tool allows for quick isolation of network issues to ensure superior call quality.
