document: Multi-timescale Internet traffic engineering The Internet is a collection of packet-based hop-by-hop routed networks . Internet traffic engineering is the process of allocating resources to meet the performance requirements of users and operators for their traffic . Current mechanisms for doing so , exemplified by TCP 's congestion control or the variety of packet marking disciplines , concentrate on allocating resources on a per-packet basis or at data timescales . This article motivates the need for traffic engineering in the Internet at other timescales , namely control and management timescales , and presents three mechanisms for this . It also presents a scenario to show how these mechanisms increase the flexibility of operators ' service offerings and potentially also ease problems of Internet management
