概要	Network Function Virtualization (NFV) has been widelyspread for software-level network configuration. Such functionalitiesinteract each other to achieve data-flow processing,named as Service Function Chaining (SFC). In SFC,each execution unit, named as Virtualized Network Function(VNF), has dependencies with others. Such configuration isrealized by allocating each VNF to a VM. Conventional approachesmainly focus on how to allocate each VNF to a VM,or how to select a VNF and they are resolved separately. Inthis paper, we propose a VNF clustering algorithm, calledClustering for Minimizing Worst Schedule Length for VNF(CMWSL-VNF) to resolve both VNF allocation and VNFselection simultaneously. CMWSL-VNF can greatly reducethe data communication latency and maintains the degree ofparallelism by the clustering algorithm. Experimental resultsshow that CMWSL-VNF can utilize vCPUs to minimize theresponse time.
