Optimizing Service Function Chaining Migration With Explicit Dynamic Path
IEEE Access, 2022 Network Function Virtualization (NFV) can support customized on- demand network services with flexibility and cost-efficiency. Virtual Network Function (VNF) instances need to be scaled out, scaled in, and reallocated across the NFV infrastructure (NFVI)

Distributed Service Function Chaining [PDF]
IEEE Journal on Selected Areas in Communications, 2017 A service-function chain, or simply a chain, is an ordered sequence of service functions, e.g., firewalls and load balancers, composing a service. A chain deployment involves selecting and instantiating a number of virtual network functions (VNFs), i.e., softwarized service functions, placing VNF instances, and routing traffic through them.

Prioritized Deployment of Dynamic Service Function Chains [PDF]
IEEE/ACM Transactions on Networking, 2021 Service Function Chaining and Network Function Virtualization are enabling technologies that provide dynamic network services with diverse QoS requirements. Regarding the limited infrastructure resources, service providers need to prioritize service requests and even reject some of low-priority requests to satisfy the requirements of high-priority ...
