Section 8: QoS

Q: Do you just want me to configure custom queuing for voice?

A: No, you must ensure that voice is transmitted within 10 ms intervals so the quality is not impaired.

Q: Do you want the QoS for the voice when it is transmitted over Frame Relay or ISDN?

A: It is your decision how and where you activate QoS, sufficient information is available in the paper for you to make an informed decision.

Q: For R5 packet fragmentation, is it acceptable to work out the smallest MTU in the network and configure this on all interfaces on R5?

A: Although this might reduce fragmentation at other points within the network, it does not allow R5 to determine the fragmentation itself.
