This document specifies the Service Attributes that need to be agreed between a Service Provider and a Subscriber for IP Services, including IP VPNs, cloud access and Internet access. Some key concepts are introduced, including IP UNIs, IP Virtual Connections, IP Virtual Connection End Points and IP UNI Access Links. Specific Service Attributes and corresponding behavioral requirements are defined for each of these entities. These include support for assured services, e.g. multiple Classes of Service, performance objectives specified in a Service Level Specification, and Bandwidth Profiles.
 Private cloud access is deferred to a future revision of this document.
