Cooperation and QoS in Fast Packet Networks: The View from the Edge
The fundamental architecture of the current generation Internet has changed little over the past two decades. This is a problem when services need to be introduced that require something more than basic point-to-point connectivity, such as needing some form of QOS or multicast capability. Multiple ownership of the Internet is both a strength and a weakness — what incentives do ISPs have to evolve their architec-tures? At the same time, processing power and intelligence is increasing at the edge of the network, which can be harnessed to create new services. For example, adaptive network-aware applications can react to changing network conditions, while P2P overlay networks can bypass many of the underlay’s inherent restrictions.
