A Framework for Quality of Service Control Through Pricing Mechanisms

S. Shelford, E.G. Manning, G.C. Shoja
2006 2006 IEEE/IFIP Network Operations and Management Symposium NOMS 2006  
Most research in network pricing focuses on improving QoS for a single network.  ...  Finally, since we cannot expect all ISPs to offer QoS-Transit Services, we describe the concept of Overlay ISPs: ISPs who provide QoS-Transit Services by controlling an overlay network.  ...  QoS in current transit agreements is specified by a Service Level Agreement (SLA), which usually defines the maximum delay and packet loss for a network.  ...
