Abstract

   Network administrators typically enforce Quality of Service (QoS)
   policies according to Service Level Agreement (SLA) with their
   providers.  The enforcement of such policies often relies upon
   vendor-specific configuration language.  Both learning of SLA, either
   thru SLA documents or via some other out-of-band method, and
   translating them to vendor specific configuration language is a
   complex, often manual, process and prone to errors.

   This document specifies an optional transitive attribute to signal
   SLA parameters in-band, across administrative boundaries (considered
   as Autonomous Systems (AS)), thus simplifying and facilitating some
   of the complex provisioning tasks in situations where BGP is
   available as a routing protocol.
