ABSTRACT
Enterprises today face several challenges when hosting line-of-business
applications in the cloud. Central to many of these challenges is the
limited support for control over cloud network functions, such as,
the ability to ensure security, performance guarantees or isolation,
and to flexibly interpose middleboxes in application deployments.
In this paper, we present the design and implementation of a novel
cloud networking system called CloudNaaS. Customers can lever-
age CloudNaaS to deploy applications augmented with a rich and
extensible set of network functions such as virtual network isola-
tion, custom addressing, service differentiation, and flexible inter-
position of various middleboxes. CloudNaaS primitives are directly
implemented within the cloud infrastructure itself using high-speed
programmable network elements, making CloudNaaS highly effi-
cient. We evaluate an OpenFlow-based prototype of CloudNaaS
and find that it can be used to instantiate a variety of network func-
