On Dynamic Service Function Chain Deployment and Readjustment
IEEE Transactions on Network and Service Management, 2017Network function virtualization (NFV) is a promising technology to decouple the network functions from dedicated hardware elements, leading to the significant cost reduction in network service provisioning. As more and more users are trying to access their services wherever and whenever, we expect the NFV-related service function chains (SFCs) to be ...

Near-Optimal Deployment of Service Chains by Exploiting Correlations Between Network Functions
IEEE Transactions on Cloud Computing, 2020A modern Network Function Virtualization (NFV) service is usually expressed in a service chain that contains a list of ordered network functions, each can run in one or multiple virtual machines. Although lots of efforts have been devoted to service chain deployment, the researchers normally consider a simple model of network functions where different ...

On the Effective Parallelization and Near-Optimal Deployment of Service Function Chains
IEEE Transactions on Parallel and Distributed Systems, 2021Network operators compose Service Function Chains (SFCs) by tying different network functions (e.g., packet inspection, flow shaping, network address translation) together and process traffic flows in the order the network functions are chained. Leveraging the technique of Network Function Virtualization (NFV), each network function can be “virtualized”

Service Function Chain Deployment with Guaranteed Resilience
2020 IEEE 17th International Conference on Mobile Ad Hoc and Sensor Systems (MASS), 2020Network Function Virtualization (NFV) transforms the implementation of network functions from expensive hardwares to software middleboxes. These software middleboxes, also called Virtual Network Functions (VNFs), are executed on virtualization platforms, which makes them more prone to error compared to dedicated hardwares. One effective way of ensuring

Service Function Chain Deployment for 5G Delay-Sensitive Network Slicing
2021 International Wireless Communications and Mobile Computing (IWCMC), 2021In recent years, Industrial Internet of Things (IIoT) has been at a high-speed development stage. However, the diversity of services and technical standards in the Industrial Internet of Things and vertical industries makes it impossible for the existing communication technologies to use the same physical network to meet different needs of services. To

Hybrid Service Chain Deployment in Networks with Unique Function
ICC 2019 - 2019 IEEE International Conference on Communications (ICC), 2019In Network Function Virtualization (NFV), Service Function Chain (SFC) is composed of Virtual Network Function (VNF) nodes that are chained via VNF links. SFCs can be specified as unidirectional or bidirectional. A unidirectional SFC (u-SFC) demands the traffic being forwarded via the VNFs in one direction, while a bidirectional SFC (b-SFC) requires ...

A Service Function Chain Deployment Scheme Based on Heterogeneous Backup
2018 IEEE 18th International Conference on Communication Technology (ICCT), 2018Building a service function chain (SFC) based on Virtual Network Functions (VNFs) greatly improves the flexibility of network service deployment. However, compared to highly reliable carrier-grade proprietary hardware, VNF is facing a series of failure risks.

Enabling Efficient Network Service Function Chain Deployment on Heterogeneous Server Platform
2018 IEEE International Symposium on High Performance Computer Architecture (HPCA), 2018Network Function Virtualization (NFV) aims to run software-implemented network functions on general hardware such as Commodity Off-the-Shelf (COTS) servers to trade the application-specific performance with generality and re-configurability. Nevertheless, with the wide adoption of general accelerators such as GPU, the researchers seek to boost the ...
