The Vigor3300B+ is an enterprise-level router for small and medium sized companies. It contains robust firewall, load balance, web content filtering, bandwidth QoS guarantee, management, secure administration, and high availability capabilities to meet the increasing demand for reliable, security broadband business services. The load balance and high availability features improve the network performance, scalability, and reliability in Internet networks. The QoS (Quality-of-Service) function provides better services for selected network traffic over lots of various technologies. The primary goal of QoS is to provide priority including dedicated bandwidth, controlled jitter and latency, and improve packet-loss characteristics. At the same time, product ensures the priority of one or more flows without making other flows fail. Robust firewall features provide rich security services including Stateful Packet Inspection(SPI), access control, packet filtering, securing against intruders/attackers and Denial-of-Service (DoS). Integrated content filtering function can block inappropriate web contents for protection on campuses or offices, as well as monitor and avoid prohibited web contents for employees. Benefits 3 WAN interfaces with load balance. Load balance/backup solution ensures high stability for network and applications. QoS function provides 8 service classes for accessing traffics in Internet. Bandwidth-guaranteed for real-time applications and on-line games. Robust firewall for securing against intruders / attackers and Denial-of-Service (DoS). Web content filtering to block inappropriate or non-productive contents. High availability provides a non-stop and reliable network access. Fail-over provides a backup service for users to Internet. Port mirroring function provides the best network monitoring and trouble shooting. Easy installation, configuration, and management through user-friendly WEB interface.

Firewall Security The default security policy with in a firewall appliance is preventing outside parties (hacker or intruder ) from accessing internal LAN resources. Vigor3300 series of routers provide such a protection in a network environment. It also support technologies of stateful packet inspection, access control, packet filtering, securing against intruders/attackers and Denial-of-Service (DoS) to provide rich security services. All packets passing through the firewall are analyzed against the state of these trusted connections to determine if they are allowed to pass through or denied. Load Balancing & Redundancy Users can choose "Load Balancing" or "Redundancy" for a reliable Internet access. The bandwidth can be increased and traffics can be shared by multi-WAN connections in the Load Balancing feature, Redundancy provides a back-up using for users to Internet. When the Master WAN failed, the Slave WAN would take over Master immediately. QoS This feature allows the network administrator to monitor, analyze, and allocate bandwidth for various types of network traffic in real-time and / or for business-critical traffic. High Availability This feature provides a non-stop and reliability network access devices. The cluster system contains two same Vigor3300 series devices. if the master is failure, the slave will take over the master's job.
