SERVICE FUNCTION CHAINING NETWORK SYSTEM FOR SETTING OPTIMAL ROUTE AND METHOD THEREOF

摘要

The present invention relates to a service function chaining network system for setting an optimal route, in a service function chaining network system including a control place and a data place, comprises: the control plane which receives input of traffic flow information and information of each node from the data plane, calculates a plurality of routes for chaining of each service function to correspond to a predetermined condition of each node, determines flow to be distributed to a route corresponding to the same, and transmits the resu and the data plane which receives input of the flow and the route result, transmitted from the control plane, and assigns the flow to each route. According to the present invention, an optimal route for each service function chaining (SFC) is determined by considering each SF instance arrangement type and linkage characteristics of a virtual link in a service function chaining network. Incoming traffic flow is optimally assigned to each node and provided. Accordingly, a mobile service provider can maximize a resource utilization rate without wasted resource.;COPYRIGHT KIPO 2017
