A Protocol to Support Multi-domain Auditing of Internet-based Transport Services
Frank Eyermann, Burkhard Stiller · 2007
Auditing of Service Level Agreements (SLA) defines the process of monitoring whether a service provider delivers agreed upon service levels or not. While frameworks exist to monitor application-level SLAs, the end-to-end monitoring of IP- carrying SLAs, especially in a multi-domain environment like the Internet, is still an open issue. This work analyzes methodologies how IP-carrying SLA parameters could be efficiently measured and develops a protocol, which supports this process and minimizes overhead.
