QoS technology enables high-quality IP voice and video.

Article Summary:

When Cisco IT migrated its voice and video traffic to IP, the network was not prepared for such bandwidth-intensive applications. Implementing quality of service (QoS) policies on both the LAN and WAN was critical to supporting voice and video.

This case study describes how Cisco IT planned and implemented QoS across the global network, including:

  • Defining the trusted edge
  • Marking seven classes of traffic
  • Using Low Latency Queuing (LLQ) and Class-Based Weighted Fair Queuing (CBWFQ) to shape traffic
  • Deploying these policies across the network
