                 Cisco Service Level Assurance Protocol
                      draft-cisco-sla-protocol-03

Abstract

   Cisco's Service Level Assurance Protocol (Cisco's SLA Protocol) is a
   Performance Measurement protocol that has been widely deployed.  The
   protocol is used to measure service level parameters such as network
   latency, delay variation, and packet/frame loss.  This draft
   describes the Cisco SLA Protocol UDP measurement type to enable
   vendor interoperability.
