Nicolas Huin, Brigitte Jaumard, Frederic Giroire
2017 2017 IEEE International Conference on Communications (ICC)  
The challenge is then to efficiently provision the service chain requests, while finding the best compromise between the bandwidth requirements, the number of locations for hosting Virtual Network Functions  ...  We conduct extensive numerical experiments, and show we can solve exactly the routing of service chain requests in a few minutes for networks with up to 50 nodes, and traffic requests between all pairs  ...  The objective is to minimize the amount of bandwidth used in the SDN network in which all service chains are provisioned.  ...

Context-aware service composition and delivery in NGSONs over SDN

Federica Paganelli, Mehmet Ulema, Barbara Martini
2014 IEEE Communications Magazine  
Moreover, the deployment of middleboxes exacerbates the rigidity of service deployment processes by imposing static chains of network appliances without considering specific service delivery requirements  ...  However, the NGSON intermediation role is not trivial due to the divergent interests of overthe-top (OTT) service providers and network operators in terms of business and service provisioning models.  ...  Second, the sequence of network functions is decided at the initial network design time and statically provisioned as stationary network service chains without considering specific packet flow requirements  ...
