# Class CIM_AFRelatedServices

The IETF's RFC2597 describes a Differentiated Services Per-Hop-Behavior (PHB) Group called Assured Forwarding (AF). Quoting from the RFC, 'The AF PHB group provides delivery of IP packets in four independently forwarded AF classes. Within each AF class, an IP packet can be assigned one of three different levels of drop precedence.' The AFRelatedServices association describes the precedence of the individual AF drop-related Services within an AF IP packet-forwarding class.
