Nevertheless, such infrastructures usually require network administrators to perform a wide set of complex planning and management tasks trying to attain adequate network configurations. Many of such management tasks can be mathematically formulated as NP-hard optimization problems, sometimes involving several objective functions. In this context, this work explores and demonstrates the potential of using computational intelligence methods as optimization engines to tackle complex network optimization problems. In particular, Multi-objective Evolutionary Algorithms (MOEAs) are used to attain near-optimal link state routing configurations robust to distinct operational conditions. As result, network administrators will be provided with a set of alternative routing configurations representing distinct tradeoffs between the considered optimization goals. The robustness of the proposed methods is illustrated by presenting several multiobjective optimization examples able to improve the performance and resilience levels of a network infrastructure. In this perspective, this work presents a contribution for this research area by proposing specific MOEAs based optimization methods able to improve network routing configurations. Furthermore, the devised methods are also integrated in a freely available Traffic Engineering optimization framework able to be used by network administrators interested in improving the routing configurations of their network infrastructures. date: 2016-09 date_type: published official_url: http://dx.doi.org/10.24138/jcomss.v12i3.79 oa_status: green full_text_type: pub language: eng primo: open primo_central: open_green article_type_text: Journal Article verified: verified_manual elements_id: 1522928 doi: 10.24138/jcomss.v12i3.79 lyricists_name: Rio, Miguel lyricists_id: MJGRI50 actors_name: Smith, Daniel actors_id: DSMIT53 actors_role: owner full_text_status: public publication: Journal of Communications Software and Systems volume: 12 number: 3 pagerange: 145-156 issn: 1845-6421 citation: Sousa, P; Pereira, V; Cortez, P; Rio, M; Rocha, M; (2016) A framework for improving routing configurations using multi-objective optimization mechanisms.
