摘要: Network Function Virtualization (NFV) enables flexible implementation and provisioning of network functions as virtual machines running on commodity servers. Due to the availability multiple hosting servers, such (also called Virtual Functions (VNFs)) can be placed where they are actually needed, dynamically migrated, duplicated, or deleted according current requirements. However, placement VNFs within physical is one main challenges in NFV domain it has a critical impact performance network. In this work we focus efficient Security (VSNFs), i.e. whose purpose prevent mitigate security threats. regard, tackle problem not only considering optimization aspects, but also trying find solutions that consistent from viewpoint. Specifically, contribution paper formulation by taking into account both Quality Service (QoS) requirements user applications.
