Service Level Agreement for DiffServ - based services provisioning

The evolution of mechanisms for providing Quality-of-Service (QoS) over the contemporary
network infrastructures has introduced the need for regulation and management of the emerging QoS
services with the use of Service Level Agreements (SLAs). SLAs define the qualitative and
quantitative characteristics of the services provided from a network provider to peering networks or
customers. In this work, we define a template for the SLA structure to support the provision of a QoS
service between two peering domains and then we proceed with the definition of an end-to-end SLA
across consecutive domains, based on the bilateral ones. We also propose a model for the service
provisioning procedures.
