Executive Summary

Today's Internet provides access to a large variety of services, which require high data rates and stable data flows for satisfactory service quality. New interactive services have high Quality of Service (QoS) requirements to the network. Packet loss, jitter, delay and effectively available bandwidth are parameters that heavily influence the Quality of Experience (QoE) of a user. The current architecture of the Internet cannot support these QoS requirements on a global scale, as solutions of one Internet Service Provider (ISP) do not necessarily work across borders of ISP domains.
