ZyXEL nbg-334w Guia De Especificação

nbg334w

With ZyXEL’s exclusive Media Bandwidth Management v2 (MBM v2), 

the NBG334W provides the most comprehensive way to smartly manage 

your limited bandwidth for multimedia applications.

The NBG334W 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 NBG334W 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.
