In this era of constant evolution of Internet, Network Virtualization is a powerful platform for the existence of heterogeneous and customized networks on a shared infrastructure. Virtual network embedding is pivotal step for network virtualization and also enables the usage of virtual network mapping techniques. The existing state- of-the-art mapping techniques addresses the issues relating to bandwidth, processing capacity and location constraints very effectively. But due to the advancement of real- time and delay sensitive applications on the Internet, there is a need to address the issue of delay in virtual network mapping techniques. As none of the existing state- of-the-art mapping algorithms do not address this issue, in this thesis we address this issue using VHub-Delay and other mapping algorithms. Based on the study and observations, we designed a new mapping technique that can address the issue of delay and finally the effectiveness of the mapping technique is validated by extensive simulations.
