Managing and Orchestrating Cross-Cloud VNFs with Deployable Sidecar VNF Coordinators
2024 IEEE 10th International Conference on Network Softwarization (NetSoft)This work presents a novel approach for managing and orchestrating Virtual Network Functions (VNFs) across cloud domains. We introduce deployable Sidecar VNF (S-VNF) coordinators designed for seamless integration into existing infrastructure, enabling operators to leverage infrastructure services provided by different providers.

Coordination-Free Multi-Domain NFV Orchestration for Consistent VNF Forwarding Graph Reconfiguration
IEEE Transactions on Network and Service Management, 2022 International audienceMulti-domain federations support shared network services. Many orchestrators manage the service's lifecycle. For the shared VNF Forwarding Graph (VNF-FG) reconfiguration, orchestrators update the graph's logical information ...

A Framework Integrating FPGAs in VNF Networks
2021 12th International Conference on Network of the Future (NoF), 2021Future telecommunications networks require more throughput and lower latency. The slowdown of Moore’s Law forces one to think beyond traditional CPU servers to satisfy these needs. FPGAs have been shown to provide exceptional throughput and latency, but they currently lack support for many of the orchestration and reconfiguration tools required by ...

Hieff: Enabling Efficient VNF Clusters by Coordinating VNF Scaling and Flow Scheduling
2020 IEEE 39th International Performance Computing and Communications Conference (IPCCC), 2020A cluster of Virtual Network Functions (VNF) can serve massive fluctuating traffic by managing VNF instances and distributing flows. However, how to schedule the flows and manage VNF scaling efficiently in a VNF cluster is still an open question. Existing solutions such as hash based schemes encounter imbalance and passive flow remapping obstacles ...

Securing VNF communication in NFVI
2017 IEEE Conference on Standards for Communications and Networking (CSCN), 2017In a modern telco cloud, network functions are performed by groups of single or interconnected virtual machines (VMs), which form virtualized network functions (VNFs). Securing these VNFs is both important and challenging, since the VNFs might be performing some mission critical operations and exchanging sensitive information among each other.
