Traffic engineering towards the assurance of quality in IP networks: trends and perspectives

The need for establishing bandwidth guaranteed paths in IP networks and the requirement for making optimal use of the available resources becomes more and more crucial due to the significant development of data-intensive multimedia applications. In this paper, we discuss the techniques and the mechanisms for exercising traffic engineering in contemporary IP networks under the prism of exploiting historical monitoring information collected from the operational environment.Keywords: Traffic engineering, history monitoring information, traffic matrix, QoS

Internet Traffic Engineering: History monitoring information featuring routing algorithms

As Internet evolves into a standard communications network, new techniques for the management of the available assets must be introduced. This paper discusses the mechanisms of exercising traffic engineering in IP networks. It provides a thorough analysis of the existent traffic engineering approaches and focuses on presenting the most recent proposals made in the specified area. The interesting point of the research efforts reviewed is that they all follow the growing trend of incorporating history monitoring information in route determination procedure. We finally conclude with the formulation of a history aware traffic engineering model
