    abstract =  {In a SFC, sometimes some SFs are provided by several DC networks, which means these SFs my locates in different DC network . How to establish such SFC that is across several DCs is what the draft wants to present. In this document, a hierarchical SFC method is proposed. It covers data plane, control plane to archieve such hierarchical SFC. And it includes requirements of the SFC Gateway for every DC network that provide SF for SFC.},
