  • Page What allows all this (atm, fr, voice, video, circuit emulation pirvate lnie, IP and SNA traffic)to ride over the same infrastructure is the built in service quality offered by ATM. It is upside benefit paid for by the infamous “cell tax”. For example QoS in the internet today is in the hope and pray best efforts class for service. Ascend in it IP Navigator product can deliver Absolute QoS for provisioned connections and SVC connections. This is a guaranteed bandwidth and connection QoS service class. We have to bridge the gap between Absolute and hope and pray QoS. The is the area of relative QoS. This is where we can take advantage of the IP header type of service field.
