Virtual Network Simulator Architecture

Abstract

Network virtualization is seen as a promising concept for the future Internet. It offers high efficiency and flexibility, and is a good candidate to address the ossification of the Internet. It is also a key enabler for resilient and low latency cloud services. Network virtualization is also expected to give rise to new business roles. Therefore, these business roles, their responsibilities and their interactions should be deeply analysed. Understanding the effects of design decisions and parameter settings in a virtual network ecosystem can be achieved by modelling and simulation. In this paper, we introduce a new simulation environment, in which a network virtualization ecosystem with its all players and the infrastructures they possess can be modelled, and the performance of new designs for efficient and resilient virtual networks and cloud connections can be assessed.
