Traffic engineering in segment routing networks
Segment routing (SR) has been recently proposed as an alternative traffic engineering (TE) technology enabling relevant simplifications in control plane operations. In the literature, preliminary investigations on SR have focused on label encoding algorithms and experimental assessments, without carefully addressing some key aspects of SR in terms of the overall network TE performance. In this ...
متن کاملPMSR - Poor Man's Segment Routing, a minimalistic approach to Segment Routing and a Traffic Engineering use case
The current specification of the Segment Routing (SR) architecture requires enhancements to the intradomain routing protocols (e.g. OSPF and IS-IS) so that the nodes can advertise the Segment Identifiers (SIDs). We propose a simpler solution called PMSR (Poor Man’s Segment Routing), that does not require any enhancement to routing protocol. We compare the procedures of PMSR with traditional SR,...
متن کاملOn Traffic Engineering with Segment Routing in SDN based WANs
Segment routing is an emerging technology to simplify traffic engineering implementation in WANs. It expresses an end-to-end logical path as a sequence of segments, each of which is represented by a middlepoint. In this paper, we arguably conduct the first systematic study of traffic engineering with segment routing in SDN based WANs. We first provide a theoretical characterization of the probl...
متن کاملA robust engineering approach for wind turbine blade profile aeroelastic computation
Wind turbines are important devices that extract clean energy from wind flow. The efficiency of wind turbines should be examined under various working conditions in order to estimate off-design performance. Numerous aerodynamic and structural research works have been carried out to compute aeroelastic effects on wind turbines. Most of them suffer from either the simplicity of the modelling appr...
