Achieving sub-second IGP convergence in large IP networks
- …We describe and analyse in details the various factors that influence the convergence time of intradomain link state routing protocols. This convergence time reflects the time required by a network to react to the failure of a link or a router. To characterise the convergence process, we first use d…

Avoiding disruptions during maintenance operations on BGP sessions
- …Abstract — This paper presents a solution aimed at avoiding Losses of Connectivity when an eBGP peering link is shut down by an operator for a maintenance. Currently, shutting down an eBGP session can lead to transient Losses of Connectivity even though alternate path are available at the borders of…

Sequence Analysis by Additive Scales: DNA Structure for Sequences and Repeats of All Lengths
- …Motivation: DNA structure plays an important role in a variety of biological processes. Different di- and trinucleotide scales have been proposed to capture various aspects of DNA structure including base stacking energy, propeller twist angle, protein deformability, bendability, and position prefer…

Avoiding Transient Loops during IGP Convergence in IP Networks
- …When the topology of an IP network changes due to a link failure or a link metric modification, the routing tables of all the routers must be updated. Each of those updates may cause transient loops. In this paper, we prove that by ordering the updates of the routing tables on the routers, it is pos…

H infinity and LMMSE Based Capacity Predictors for Flow Control in Communication Networks
- …Recently developed robust controllers for flow control in communication networks with single bottleneck node use the explicit queue length information as the only measured signal to assign the flow rates to the sources. In this paper, we assume that outgoing flow rate can also be measured, and inves…

Controller Design for Congestion Control with a Capacity Predictor
- …In this paper we investigate the use of capacity information in the H 1 controller design for rate based ow control in high speed communication networks for the case of a single bottleneck node and a single source. In the previous works in this line of research it was assumed that the controller h…

Achieving Sub-50 Milliseconds Recovery upon BGP Peering Link Failures
- …We first show by measurements that BGP peering links fail as frequently as intradomain links and usually for short periods of time. We propose a new fast-reroute technique where routers are prepared to react quickly to interdomain link failures. For each of its interdomain links, each router precom…

Phase-by-Phase Schedules for identical Malleable Tasks
- …sive layers with a global synchronization. If we restrict to identical MT, the problem is in O(nm) and we may nd the optimal solution with an algorithm using dynamic programming techniques. We can establish that the optimal phase-by-phase schedule is always larger or equal to the optimal schedule in…

Polynomial Upwind Schemes for Hyperbolic Systems.
- …. In this paper, we present an upwinding methodology for systems of conservation laws. Our aim is to construct upwind schemes which do not require the extraction of the eigensystem of the jacobian matrix (but just the knowledge of the eigenvalues) and rely on the introduction of an appropriate polyn…
