In this paper, we are proposing an Inter-domain traffic engineering architecture over a Bandwidth Broker (BB) supported Diffserv internet. The main components of our architecture are a novel inter-domain QoS routing architecture, the addition of an explicit path setup capability to the Simple Inter-domain Bandwidth Broker Signaling (SIBBS) protocol, and inter-domain label switched path (LSP) se...

An important requirement of a robust traffic engineering solution is insensitivity to changes, be they in the form of traffic fluctuations or changes in the network topology because of link failures. In this paper we focus on developing a fast and effective technique to compute traffic engineering solutions for OSPF/IS-IS environments that are robust to link failures in the logical topology. OS...

The demand for multimedia applications along with rapid growth, the need for quality of service, reliability, and resilience have made traffic engineering an essential consideration in the design and operation of large public Internet backbone networks. In order for carriers to minimize the financial impact of inevitable link and network component failures, backbone protection solutions must be...

The overlay approach has been widely used by many service providers for traffic engineering 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 conne...

This paper proposes an integrated network management framework for inter-domain outbound traffic engineering. The framework consists of three functional blocks (monitoring, optimization and implementation) to make the outbound traffic engineering adaptive to network condition changes such as inter-domain traffic demand variation, inter-domain routing changes and link failures. The objective is ...

This paper presents a new hybrid traffic engineering routing algorithm for bandwidth guaranteed traffic. Former traffic engineering routing algorithms mainly optimize one of the three objectives: minimizing the hop count, balancing the load and minimizing the interference between source-destination pairs. But usually there is a tradeoff among these three factors. Single objective optimizations ...

This paper studies the effect of simple Traffic Engineering techniques on the size of the Internet’s default free routing table. Current best practises for traffic balancing in the Internet are based in disaggregating prefixes that cause an increase in size of the Internet’s core routing table. An algorithm to show the impact of these techniques on the growth of the routing table is proposed. T...

In this paper we propose a model for measurementbased network configuration. In the model, resource allocation is based on provisioning cycles, whereby monitoring is used to build a matrix with expected traffic patterns. Such a matrix drives the subsequent network configuration phase, which is performed via a hybrid Traffic Engineering approach, combining both off-line and on-line algorithms. F...

Far too many courts lack interest in either education or engineering. This also can be applied to the police departments. In too many in­ stances educators are indifferent to the courts, police and engineering. Not desiring to point an accusing finger, it is felt that traffic engineer­ ing falls as short of perfection in this regard as the other fields of re­ sponsibility in traffic safety. If,...
