QoS Controllers for the Internet

In this position paper, we review basic control strategies that machines acting as traffic controllers could deploy in order to improve the management of Internet services. Such traffic controllers are likely to spur the widespread emergence of advanced applications, which have (so far) been hindered by the inability of the networking infrastructure to deliver on the promise of Quality-of-Service (QoS). I. INTRODUCTION To deliver QoS, the Internet of tomorrow is expected to implement smarter bandwidth management. Network support for QoS will eliminate the cost of over-provisioning while enhancing the commercial competitiveness of Internet service providers and carriers. We believe that one result of this trend will be the widespread emergence of machines acting as traffic controllers. These controllers (i) should be placed in strategic places in the Internet (e.g., in front of clients/servers or at exchange/peering points between administrative domains), (ii) should be capable of qui...
