Middleboxes are widely deployed to perform various network functions to ensure security and improve performance. The recent trend of Network Function Virtualization (NFV) makes it easy for operators to deploy software implementations of these network functions on commodity servers. However, virtual network functions consume different amounts of resources when processing packets. Thus a multi-resource...
Middleboxes are prevalent in today's enterprise and data center networks. Network function virtualization (NFV) is a promising technology to replace dedicated hardware middleboxes with virtualized network functions (VNFs) running on commodity servers. However, no prior study has examined the energy efficiency of different NFV implementations. In this paper, we conduct a measurement study on the power...
As applications grow more and more complex, the current software faces a great challenge in dynamism. This paper proposes to modernize legacy software towards runtime plug-and-play architecture using service-oriented component model. Our object is to provide runtime plug-and-play feature for software to simplify development and adapt to changing execution environment. We propose a two-stage modernization...
