A Meta Reinforcement Learning Approach for SFC Placement in Dynamic IoT-MEC Networks
Applied Sciences, 2023 In order to achieve reliability, security, and scalability, the request flow in the Internet of Things (IoT) needs to pass through the service function chain (SFC), which is composed of series-ordered virtual network functions (VNFs), then reach the ...

Joint VNF Placement and CPU Allocation in 5G [PDF]
IEEE INFOCOM 2018 - IEEE Conference on Computer Communications, 2018 Thanks to network slicing, 5G networks will support a variety of services in a flexible and swift manner. In this context, we seek to make high-quality, joint optimal decisions concerning the placement of VNFs across the physical hosts for realizing the services, and the allocation of CPU resources in VNFs sharing a host.

VNF Placement and Sharing in NFV-based Cellular Networks [PDF]
, 2020 Network Function Virtualization is one of the most relevant enabling technologies for 5G: conceiving a vertical service as a set of virtual functions (a.k.a. VNFs) makes it possible to implement a service at the network edge in a fast and flexible manner,

Online and batch algorithms for VNFs placement and chaining [PDF]
Computer Networks, 2019 This paper proposes an Integer Linear Program (ILP) to address the Virtualized Network Function Forwarding Graph (VNF-FG) placement and chaining problem when VNFs are shared across tenants to optimize resource usage and increase provider revenue. Since ILP based approaches do not scale well with problem size, the proposed algorithm (R-ILP for reduced ...

VNF placement with replication for Loac balancing in NFV networks [PDF]
2017 IEEE International Conference on Communications (ICC), 2017 Network Function Virtualization (NFV) is a new paradigm, enabling service innovation through virtualization of traditional network functions located flexibly in the network in form of Virtual Network Functions (VNFs). Since VNFs can only be placed onto servers located in networked data centers, which is the NFV's salient feature, the traffic directed ...
