White Paper Abstract:
This paper aims to address the topic of quality of service (QoS) and the tools available from Cisco Systems for designing a Virtual Private Network (VPN) with appropriate service levels for mission critical applications. This paper is not meant to be a design guide but more of a glimpse into some of the QoS technologies available from Cisco to help implement a successful VPN. The audience is expected to be familiar with VPN related issues such as security, firewalls, and routing/switching offerings from Cisco.
This paper also provides an introduction to the end-to-end QoS architecture for VPNs from Cisco, including rich classification, policing, shaping, queuing and congestion avoidance. The paper also touches upon the future of QoS policy deployment using Common Open Policy Service (COPS) and Cisco QoS policy servers.
