QoS Version 2 yields consistent management and performance standards across LAN and WAN.

Propelled by increased demand for voice, video, and other bandwidth-intensive business applications, such as desktop videoconferencing, in 2003 Cisco IT began to develop what it called “quality of service (QoS) Version 2.” This end-to-end solution would address the network consistently across user devices from the LAN edge to the enterprise WAN edge.

This case study provides Cisco IT lessons learned and the business benefits from this QoS implementation, including:

  • Decreased voice-application-related help desk calls
  • Fewer support problems with applications that have strict host-to-host latency requirements
  • The ability to more intelligently address network capacity issues
  • Consistent standards across the hardware and software infrastructures
