With the advances of network function virtualization and cloud computing technologies, a number of network services are implemented across data centers by creating a service chain using different virtual network functions (VNFs) running on virtual machines. Due to the complexity of network infrastructure, creating a service chain requires high operational cost especially in carrier-grade network service...
With the advances of network function virtualization (NFV) and cloud computing technologies, a number of network services are implemented across data centers by chaining different virtual network functions (VNFs) running on virtual machines. Since these VNFs consume a large amount of resources and power from underlying physical machines, the service function chaining (SFC) algorithm should be carefully...
In the Network Function Virtualization (NFV) architecture, Network Service Chaining (NSC) is consisted in a certain order of network elements so that it can provide flexible network services to users. Due to the complexity of network infrastructure, creating a service chain requires high operation cost especially in carrier-grade network service providers and supporting stringent QoS requirements...
