Traffic management refers to controlling how much traffic traverses each path in a network. On the Internet today, end hosts run congestion control to adapt sending rates, routers route traffic on shortest paths based on link weights, and operators tune link weights to direct traffic away from heavily-loaded links. This dissertation performs a top-down redesign of traffic management to support ...

The overlay approach has been widely used by many service providers for Traffic Engineering (TE) in large Internet backbones. In the overlay approach, logical connections are set up between edge nodes to form a full mesh virtual network on top of the physical topology. IP routing is then run over the virtual network. Traffic engineering objectives are achieved through carefully routing logical ...

Traffic engineering (TE) optimizes the performance of a network by analyzing and regulating the data transmission. Traffic engineering with link coloring (TELIC) was proposed to automatically assign LSPs in multi-protocol label switching domain based on bandwidth and class of service attributes. TELIC dynamically assigns colors to links in the network domain on the basis of reservable bandwidth...

New Services IP networks offer unparalleled scalability and flexibility for rapid deployment of value-added IP services. However, with the increasing demand and explosive growth of the Internet, carriers require a network infrastructure that is dependable, predictable, and offers consistent network performance. Traffic engineering and differentiated services are the two cornerstones needed to a...

Conventional routing management approaches, which are based on given and often ”worst case” traffic matrices, are not sufficient anymore to deal with the increasing growth of the number of endpoints and diverse applications in IP networks. Traffic variations are becoming a more and more important issue, especially when making long-term network planning decisions as well as for medium-term netwo...

Traffic management is a business domain characterized by an infrastructure-dominant approach to new developments: the focus is typically on innovating assets such as traffic detection systems, road signage and traffic information systems. This domain also has a large number of involved stakeholders, such as road authorities, municipalities, technology providers and road users of various kinds. ...

In this paper we present an intelligent multi-topology IGP (MT-IGP) based intra-domain traffic engineering (TE) scheme that is able to handle unexpected traffic fluctuations with near-optimal network performance. First of all, the network is dimensioned through offline link weight optimization using Multi-Topology IGPs for achieving maximum path diversity across multiple routing topologies. Bas...

Traffic Engineering seeks to optimize the handling of the traffic in a network such that the capacity in various parts is utilized efficiently. IETF has developed new protocols and techniques to meet the emerging traffic requirements and to manage and control the network and its services. With MPLS, Diffserv, RSVP-TE/CR-LDP, SLA and COPS in place, manual provisioning of the network is impossibl...

Traffic in the Internet is known to change over time and exhibit volatile behaviour. One major challenge in communication networks is the problem of handling these traffic demands that are bursty and hard to predict. Current traffic engineering techniques operate on time scale of several hours, which is too slow to react to quick phenomena such as flash crowds or BGP reroutes. The obvious solut...

In arterial networks, the dynamics of traffic flows are driven by the presence of traffic signals. A comprehensive model of the dynamics of arterial traffic flow is necessary to capture the specifics of arterial traffic and provide accurate traffic estimation. From hydrodynamic theory of traffic flow, we model the dynamics of arterial traffic under specific assumptions which are standard in tra...
