Learn about the options and technical implementations for the various types of quality of service (QoS) required by enterprises for typical virtual private network (VPN) deployments. Service providers and enterprises typically build parallel networks to support the transport of data, voice, video and mission-critical and non-mission-critical applications. With the move toward convergence, as well as the use of packet-based IP networks, the shift from circuit-switched division and parallel builds of network resources toward a single IP network is increasing. This chapter covers the requirements for supporting the converged world of Multiprotocol Label Switching (MPLS) VPNs and how this maps to QoS policy applicable in the enterprise. The aim is to provide a deployable set of policies that the enterprise can use as guidelines. You'll also see how to address these policies to the service provider.
