The objective of this work is to implement an SDN-WAN solution to optimize the allocation of paths connecting geo-distributed data centers.
The SDN-WAN architecture adopted in this project leverages PCEP and BGP-LS protocols provided by ONOS.
To implement this architecture, we make of use ONOS framework and IOS-XR v Cisco routers. Then, we extend PCE algorithm to enhance the quality of selected paths. The results demonstrate that our approach improves QoS applications while ensuring load balancing of the network infrastructure.
