Data-driven resource flexing for network functions visualization
Lianjie Cao, Sonia Fahmy, Puneet Kumar Sharma, Shandian Zhe · 2018
Resource flexing is the notion of allocating resources on-demand as workload changes. This is a key advantage of Virtualized Network Functions (VNFs) over their non-virtualized counterparts. However, it is difficult to balance the timeliness and resource efficiency when making resource flexing decisions due to unpredictable workloads and complex VNF processing logic.
