Connectivity Manager includes the APIs between the enterprise operator and the provider network for the two parties to establish QoS parameters for enterprise network packets travelling through the provider network.
The Connectivity Manager service provides tools for the enterprise operator to set up a Provisioned QoS service in the provider network. The QoS measures used in the enterprise network are outside the scope of the service. The API does not require any specific QoS method to be used in the enterprise network, nor in the provider network. However, in order for Provisioned QoS service to be applied to packets arriving from the enterprise network into the provider network, the packets have to be marked using DS Codepoint marking. Once the packets are so marked, they can enjoy the QoS service provisioned in the provider network.
APIs provide the enterprise network operator on-line access to provision quality of service measures that control the enterprise's own traffic passing through the provider network. Using APIs the operator can create Virtual Provisioned Pipes (VPrPs) in the provider network to carry the enterprise traffic and support it with pre-specified quality of service attributes. A VPrP can be thought of as a Virtual Leased Line (VLL) provisioned to deliver pre-specified QoS.
The provider may offer to the enterprise operator a set of templates that are used by the operator to specify a VPrP. For instance, the provider may offer templates for video conferencing, audio conferencing, Gold Service, Silver Service, etc. Using these templates the operator can select and provision a VPrP that specifies the quality of service attributes for this VPrP.
Elements that can be specified for a VPrP include attributes such as packet delay and packet loss. Characteristics of traffic that enters the VPrP at its access point to the provider network can be also specified with attributes such as maximum rate and burst rate.
