摘要
A method as implemented in a controller in a SDN: (a) receiving service function chain orders of packet flows comprising a service function chain; (b) receiving, in real-time, delay measurements from either one of the virtual network functions and/or one of the network switches; (c) determining a plurality of realizations of the service function chain orders of (a) in order to minimize a total delay; (d) choosing an optimal realization corresponding to a least delay; and (e) determining one or more flow rules for the one or more network switches, the determining based on the optimal realization in (d). A controller and an article of manufacture implementing such a method are also described.
