Lesson Objectives

Congestion Avoidance

  • identify the problems that TCP congestion-management mechanisms face on converged networks.
  • identify how random early detection (RED) improves TCP traffic flow and assists traffic avoidance.
  • given a scenario, broadly determine how congestion avoidance could be implemented on TCP traffic with random early detection (RED).
  • identify the various weighted random early detection (WRED) profiles that are used in WRED implementations.
  • identify the Cisco IOS commands required to configure and monitor class-based weighted random early detection (CB-WRED).
  • identify the Cisco IOS commands required to configure explicit congestion notification (ECN) extensions to weighted random early detection (WRED) and to monitor ECN-enabled WRED.
  • given a scenario, determine a course of action for configuring DSCP-based, class-based weighted random early detection (CB-WRED) and explicit congestion notification (ECN).
