Affine Flow Thinning – a traffic routing and protection mechanism for networks with variable link capacity
Michal Pioro (Warsaw University of Technology, PL & Lund University, SE)
Abstract
Flow Thinning (FT) is a traffic routing and protection mechanism for communication networks whose links experience fluctuations in available capacity. To cope withthis phenomenon, end-to-end traffic demands are equipped with dedicated sets of logical tunnels whose nominal capacity is subject to state-dependent thinning to account for variable capacity of the links fluctuating below their nominal (maximum) values. Consequently, the instantaneous traffic sent between the demand's end nodes must accommodate to the current total capacity available on its dedicated tunnels. FTis relevant for example for wireless mesh networks utilizing MPLS tunnels. The multi-commodity flow optimization problem related to FT is NP-hard and its non-compact linear programming formulation requires path generation. The presentation is devoted to optimization modelling of Affine Flow Thinning – an important, practical version of FT, where tunnels are thinned according to a linear (affine) formula.

The Age of Programmable Networks: Algorithms for Designing Flexible and Robust SDNs
Stefan Schmid (Aalborg University, DK)
Abstract
Computer networks currently undergo a phase transition, in that they are becoming more and more programmable, and hence introduce interesting new algorithmic opportunities and flexibilities (e.g., for the design, deployment, and operation of computer networks) -- but also challenges. In this talk, I will provide an overview of these opportunities and challenges, describe algorithmic models and techniques to address them, and finally outline open questions for future research. A main focus of the talk will be on the design of robust and self-optimizing computer networks.

A practical view of modeling and quantification of network survivability
Poul E. Heegaard (Norwegian University of Science and Technology, NO)
Kishor S. Trivedi (Duke University, US)
Abstract
The goal of this tutorial is to provide an introduction to the concept and definition of survivability and to demonstrate approaches to model and quantify survivability in networks. In our tutorial we define survivability as the "ability to provide services in compliance with the requirement even in presence of major and minor failures in network infrastructure and service platforms caused by undesired events that might be external or internal". The network survivability is quantified as defined by the ANSI T1A1.2 committee, which is the transient performance from the instant an undesirable event occurs until steady state with an acceptable performance level is attained. Examples are taken from the survivability of mobile networks and virtual connection over an IP network as well as from smartgrid.
After an introduction to survivability and the modelling framework for quantification of survivability, the tutorial will present an exercise with example from a 5G mobile system. The objective with the exercise is to provide useful insight and experience with the use of an analytic tool (Sharpe), and programming of a discrete event simulator.
