Product Description ( bulky box ,never used)
With ZyXEL's exclusive Media Bandwidth Management v2 (MBM v2), the NBG-334W provides the most comprehensive way to smartly manage your limited bandwidth for multimedia applications.The NBG-334W performs stateful inspection filtering for effective network protection. With the default firewall settings, all outgoing and incoming traffic in the protected LAN is checked. The firewall feature includes TCP / UDP inspection, DoS (Denial of Services) detection and prevention, real time alert, reports and logs.Enabled by the Wi-Fi Multimedia (WMM) technology, a subset of the IEEE 802.11e WLAN QoS draft standard, the NBG-334W heightens users' experience on audio, video and voice applications over wireless networks. Without the Quality of Service (QoS) capability, all applications on different devices are given equal priority to transmit data frames; this may work well for web browsing, file transferring or emailing applications, but it is inadequate for multimedia applications such as VoIP conversation, video streaming or interactive gaming.Multimedia applications are highly sensitive to latency or throughput reductions, and they all require QoS for optimal performance. WMM defines four access categories (voice, video, best effort and background) for traffic prioritization to provide enhanced multimedia presentation.
