    abstract =  {Hierarchical Service Function Chaining (hSFC) is a network service chaining method that utilizes a hierarchical structure to efficiently organize and manage service function chains, enhancing network performance and scalability. This document primarily describes the use case of hSFC, which is the security resource pool. It outlines the associated problem statement and requirements for the security resource pool. The document aims to assist in identifying candidate solution architectures and solutions.},
