Delay-Bandwidth Optimization Method Based on Ant Colony Algorithm Applied to Transport Network Using SDN Paradigm

New Transport Technologies are being developed to support the fast growing of IP based services like video and voice, mobile broadband and Cloud. Multiprotocol Label Switching Transport Profile (MPLS-TP) is an emerging transport technology aimed to satisfy requirements of these new technologies. It is characterized by its strong Operation, Administration and Maintenance (OAM) toolbox. MPLS-TP can take advantage of Software Defined Network (SDN) which is an emerging network paradigm allowing network virtualization and offering flexibility for more innovations. Our work is based on existing Ant colony Algorithm which will be modified to fulfil MPLS-TP's requirements which are different from IP/MPLS technology. The present paper shows how we can take benefit from classical optimization methods in order to optimize resources inside a SDN based transport network using modified Ant Colony Algorithm.
