2010 Computer communication review  
SLICED PROGRAMMABLE NETWORKS OpenFlow [4] has been demonstrated as a way for researchers to run networking experiments in their production network.  ...  To motivate FlowVisor's flexibility, we demonstrate four network slices running in parallel: one slice for the production network and three slices running experimental code (Figure 1 ).  ...  The four slices (two wired and two wireless) are chosen to show the diversity of experiments that FlowVisor supports, and will each be running an isolated slice specifically "carved" for its needs.  ...

DSAF: Dynamic Slice Allocation Framework for 5G Core Network [article]

Danish Sattar, Ashraf Matrawy
2019 arXiv   pre-print
Network slicing is a key to supporting different quality-of-service requirements for users and application in the 5G network.  ...  In this paper, we extend our work to dynamically allocated slices. We propose a dynamic slice allocation framework for the 5G core network.  ...  The optimization model provided intra-slice isolation for network functions within a slices. Intra-slice isolation provides a variable degree of physical separation between slice components.  ...
