Abstract:
Disclosed in the present specification is a method by which network nodes calculate an optimum path for virtualized service functions (SFs). The method can comprise the steps of: generating a service function chain (SFC), in which SFs are put in order, on the basis of subscriber information-based user policy information, session policy information, and SF state information; searching for an optimum SF set on the basis of the SFC so as to calculate an optimum service function path (SFP); and updating the SFP when any one of the subscriber information-based user policy information, session policy information, and SF state information is changed.

Claim (Index 9):
A software defined networking (SDN) controller calculating an optimal path for service functions (SFs) in which network nodes have been virtualized, the SDN controller comprising:\n a monitoring unit monitoring a state of the SFs; a chain generator generating a sequenced service function chain (SFC) of the SFs based on user policy information based on subscriber information and state information of the SFs; and an SFP optimizer calculating an optimal service function path (SFP) by finding an optimal SF set based on the SFC.
