DSCD: Delay Sensitive Cross-Domain Virtual Network Embedding Algorithm

IEEE Transactions on Network Science and Engineering, 2020
In the coming 5G era, more and more applications are time-delay sensitive, and the importance of low delay in fields such as telemedicine, autonomous driving and military order transmission is self-evident.

A Dynamic and Collaborative Multi-Layer Virtual Network Embedding Algorithm in SDN Based on Reinforcement Learning

IEEE Transactions on Network and Service Management, 2020
Most of existing virtual network embedding (VNE) algorithms only consider how to construct virtual networks more efficiently on a physical infrastructure, without considering the possibility that the constructed virtual networks may be further ...

Network Virtualization

2017
Cloud computing is a novel paradigm which relies on the vision of resource sharing over the Internet. The concept of resource virtualization, i.e. hiding the detail specification of the resources from the end users is the key idea of cloud computing. But the tenants have limited visibility over the network resources.

Virtualizing the Network Services: Network Function Virtualization

2017
Network function virtualization (NFV) is rapidly emerging as the de facto approach operators will use to deploy their networks. NFV leverages on cloud computing principles to change the way NFs like gateways and middleboxes are offered. As opposed to today’s tightly coupling between the NF software and dedicated hardware, NFV concept requires the ...

RABA: Resource-Aware Backup Allocation For A Chain of Virtual Network Functions

IEEE Conference on Computer Communications, 2019
Network Function Virtualization (NFV) turns a sequence of network functions on hardwares into a service chain of virtual network functions (VNFs) provisioned on virtual machines or containers.
