dc.description.abstract | Network function virtualization (NFV) simplifies the
configuration and management of security services by migrating
the network security functions from dedicated hardware devices
to software middle-boxes that run on commodity servers. Under
the paradigm of NFV, the service function chain (SFC) consisting
of a series of ordered virtual network security functions is
becoming a mainstream form to carry network security services.
Allocating the underlying physical network resources to the
demands of SFCs under given constraints over time is known
as the SFC deployment problem. It is a crucial issue for
infrastructure providers. However, SFC deployment is facing new
challenges in trading off between pursuing the objective of high
revenue-to-cost ratio and making decisions in an online manner.
In this paper, we investigate the use of reinforcement learning to
guide online deployment decisions for SFC requests and propose
a Policy network Assisted Monte Carlo Tree search approach
named PACT to address the above challenge, aiming to maximize
the average revenue-to-cost ratio. PACT combines the strengths
of the policy network, which evaluates the placement potential of
physical servers and the Monte Carlo Tree Search, which is able
to tackle problems with large state spaces. Extensive experimental
results demonstrate that our PACT achieves the best performance
and superior to other algorithms by up to 30% and 23.8% on
average revenue-to-cost ratio and acceptance rate, respectively | en_GB |
