Question:
What role do network devices play in the IntServ QoS model?

  • Network devices ensure that resources are available before traffic is allowed to be sent by a host through the network.
  • Network devices provide a best-effort approach to forwarding traffic.
  • Network devices are configured to service multiple classes of traffic and handle traffic as it may arrive.
  • Network devices use QoS on a hop-by-hop basis to provide excellent scalability.

Explanation: The IntServ QoS model uses resource reservation to guarantee bandwidth and packet-loss rates from end to end. IntServ uses a connection-oriented approach to ensure that available resources are sufficient in the network for the traffic to have a specific level of QoS.
