Multi-layer traffic engineering: performance evaluation under a physical capacity constraint
Qiang Yan,Bart Puype,Ilse Lievens,Didier Colle,S. De Maesschalck,Mario Pickavet,Piet Demeester +6 more
TL;DR: In this paper, the impact of physical capacity constraint on the performance of multi-layer traffic engineering (MTE) strategies is investigated in the case of an IP-over-WDM network, where each WDM system is able to multiplex a limited number of wavelength channels onto the same fiber.
Proceedings ArticleDOI
Autonomic service hosting for large-scale distributed MOVE-services
TL;DR: Two Integer Linear Programming approaches to optimize the MOVE deployment through load balancing and minimizing the delay experienced by the end-users are detailed.

Performance Analysis of a Dynamic Compact Multicast Routing Scheme
TL;DR: By means of the proposed scheme, a multicast distribution tree can dynamically evolve according to the arrival of leaf-initiated join/leave requests and the tradeoffs between the stretch of the produced routing paths, the size and the number of routing table entries, and the communication cost.
Journal ArticleDOI
Analysis of resource sharing in transparent networks
TL;DR: This paper investigates the CapEx reductions obtained through protection sharing on a population of 1000 randomly generated biconnected planar topologies with 14 nodes and shows that the gain for transparent networks is heavily dependent on the offered load, with almost no relative gain for low load, while in transparent networks only the degree of the ROADM decreases while the number of transponders remains the same.
