Abstract:
|
Network virtualisation is considerably gaining attention
as a solution to ossification of the Internet. However, the
success of network virtualisation will depend in part on how efficiently
the virtual networks utilise substrate network resources.
In this paper, we propose a machine learning-based approach
to virtual network resource management. We propose to model
the substrate network as a decentralised system and introduce
a learning algorithm in each substrate node and substrate link,
providing self-organization capabilities. We propose a multiagent
learning algorithm that carries out the substrate network resource
management in a coordinated and decentralised way. The task
of these agents is to use evaluative feedback to learn an optimal
policy so as to dynamically allocate network resources to virtual
nodes and links. The agents ensure that while the virtual networks
have the resources they need at any given time, only the required
resources are reserved for this purpose. Simulations show that
our dynamic approach significantly improves the virtual network
acceptance ratio and the maximum number of accepted virtual
network requests at any time while ensuring that virtual network
quality of service requirements such as packet drop rate and
virtual link delay are not affected. |
