QoS and Packet Prioritization is not Enough.
        DrayTek Provides Bandwidth Management

There are different approaches to QoS. Class of service or Diffserv are many times called QoS. Bandwidth Management can also be confused with QoS.

Bandwidth Management is what we need when dealing with time sensitive traffic such as VoIP. Most networking devices claim to support QoS, even layer 2 switches. For some manufacturers QoS means setting a flag in all packets. Others would also classify and apply prioritization rules before forwarding the packets. QoS is no help when upstream modems or routers start dropping packets when the link is flooded.

In any case, only routers that support true Bandwidth Management can limit the bandwidth used by non-time sensitive applications and dynamically allocate enough to VoIP traffic. The router must be capable to slow down bandwidth hogs and connections that are less important. Even better, what if the router could also help manage the content going in and out your network? Content Management capability in the router is a great advantage. That way, undesired traffic, the users can be generating, does not even start. Only expensive high-end networking appliances supported these features until now. Draytek, a value alternative that beats the features of high-priced routers while offering more innovative features and with NO PER USER LICENCES.
