Abstract Throughout its history, Operational Research has evolved to include methods,
models and algorithms that have been applied to a wide range of contexts. This …

Throughout the last decade, extensive deployment of popular intra-domain routing protocols
such as open shortest path first (OSPF) and intermediate system–intermediate system (IS …

We consider the problem of designing lines in a public transport system, where we include
user-optimal route choice. The model we develop ensures that there is enough capacity …

Abstract The emergence of Software Defined Network (SDN) provides a centralized and
flexible approach to route network flows. Due to the technical and economic challenges in …

Internet energy consumption is rapidly becoming a critical issue due to the exponential traffic
growth and the rapid expansion of communication infrastructures worldwide. We address …

Segment Routing (SR) is a new fertile ground for Traffic Engineering (TE). By decomposing
forwarding paths into segments, which specify a list of intermediate delivery points that a …

Traffic engineering is a method to balance the flows and optimize the routing in the network.
Software defined networking is a new network architecture and we can gain great benefit by …

In this article we introduce a preprocessing technique to solve the Segment Routing Traffic
Engineering Problem optimally using significantly fewer computational resources than …

Abstract The aim of Traffic Engineering is to provide routing configurations in networks such
that the used resources are minimized while maintaining a high level of quality of service …

In this paper we address unbalanced spatial distribution of hub-level flows in an optimal hub-
and-spoke network structure of median-type models. Our study is based on a rather general …
