讲座名称：Availability-aware Resource Provisioning forNetwork Function Virtualization
As the next stepafter Software Defined Networking (SDN), network function virtualization (NFV)is emerging as a new way to provide network services that are now being carriedout by proprietary, dedicated hardware (called middleboxes) to significantlyreduce the cost as well as greatly improve the efficiency and flexibility ofutilizing hardware resources. However, since VNFs are hosted bygeneral-purposed servers or Virtual Machines (VMs), which are more prone tofailures compared to dedicated middleboxes, how to ensure a high availabilityof the provided network services is an important issue for service providers(SP).
In this talk, Iwill outline our recent work on analyzing the challenges of provisioningavailability in NFV and developing availability-aware resources allocation andplacement algorithms for both on-site and off-site backups with the objectiveof minimizing resource usage.
