Reducing Service Deployment Cost Through VNF Sharing [article]

Francesco Malandrino and Carla Fabiana Chiasserini and Gil Einziger and Gabriel Scalosub
2019 arXiv   pre-print
Importantly, one or more VNFs are often common to multiple services, thus the services deployment cost could be reduced by letting the services share the same VNF instance instead of devoting a separate  ...  load of the assigned services, and (iii) how to prioritize the services traffic within shared VNFs.  ...  Note that in the above expression equality holds since, otherwise, the service deployment cost could be further reduced.  ...
