Optimal virtual network function placement in multi-cloud service function chaining architecture
Service Function Chaining (SFC) is the problem of deploying various network service instances over geographically distributed data centers and providing inter-connectivity among them. The goal is to enable the network traffic to flow smoothly through the underlying network, resulting in an optimal quality of experience to the end-users. Proper chaining of network functions leads to optimal util...
متن کاملOrchestrating Service Function Chaining in Cloud Environments
The rapid emergence of Software Defined Networks (SDN) and Network Function Virtualization (NFV) concepts is enabling the innovation of cloud infrastructures for supporting real time services and applications. Interconnecting Service Functions (SFs) in a specific ordered way to support applications’ requirements is defining the concept of Service Function Chaining (SFC). SFC uses those evolved ...
متن کاملSICS: Secure In-Cloud Service Function Chaining
There is an increasing trend that enterprises outsource their network functions to the cloud for lower cost and ease of management. However, network function outsourcing brings threats to enterprises’ privacy since the cloud is able to access the traffic and rules of in-cloud network functions. Current tools for secure network function outsourcing either incur large performance overhead or do n...
متن کاملVirtual function placement for service chaining with partial orders and anti-affinity rules
Software Defined Networking and Network Function Virtualization are two paradigms that offer a flexible software-based network management. Service providers are instantiating Virtualized Network Functions e.g., firewalls, DPIs, gateways to highly facilitate the deployment and reconfiguration of network services with reduced time-to-value. They employ Service Function Chaining technologies to dy...
متن کاملNetwork service chaining with optimized network function embedding supporting service decompositions
The rise of Software-Defined Networking (SDN) and Network Function Virtualization (NFV) introduces opportunities for service providers to reduce CAPEX/OPEX and to offer and quickly deploy novel network services. In particular, SDN and NFV enable the flexible composition of network functions, a generic service concept known as Network Service Chaining (NSC). However, the control of resources, ma...
