Network function virtualization enables service providers to flexibly deploy network services.
The existing works mainly focus on function placement and capacity allocation without …

This paper proposes a service deployment model for network function virtualization to
minimize the deployment cost with capacity sharing and priority queuing. A service provider …

Network Functions Virtualization (NFV) has emerged as a paradigm for efficient, flexible and
agile network function provisioning. In such NFV-based networks, ensuring network …

Service chaining provides network services by flexibly configuring service chains that
connect virtualized network functions (VNFs) in the appropriate order so as to satisfy users' …

In network function virtualization, virtual network functions (VNFs) are usually chained in
specific orders to generate service function chains (SFCs). Recently, SFC parallelism has …

This paper proposes an availability-aware service provisioning model with backup sub-
chain-enabled sharing in network function virtualization to minimize the deployment cost. A …
