ABSTRACT
Because of the demand for high-performance resource allocation systems for Virtual Private Networks (VPNs), algorithms for VPN resource allocation have proliferated. The majority of VPN resource allocation research focused on either admission control or network link reserve. A survey of relevant literatures has also indicated the requirement for a resource allocation/scheduling system whose algorithm can distribute bandwidth and memory resources to distinct VPNS sharing the same network service provider link. Resources should be allocated in such a way that maximum utilization is achieved while VPN endpoints or consumers receive services that do not jeopardize the service provider’s service-level agreement (SLA). MATLAB Simulink was used to create a simulation model for analyzing the VPN access network and comparing the RDVNP (Robust Dynamic Virtual Network Provisioning) algorithm against the DWARF-Net (Dynamic bandWidth Allocation and Guarantee on Resource Fairness) algorithm in terms of link bandwidth utilization, buffer memory utilization, and packet loss rate. According to the results, the DWARF-Net method outperformed the RDVNP algorithm in practically every parameter examined. In terms of bandwidth consumption, DWARF-Net had a 61.23 percent average channel utilization compared to RDVNP’s 48.28 percent. DWARF-Net has a buffer utilization of 42%, while RDVNP has a buffer utilization of 41%. DWARF-Net has a loss rate of 1 packet per second, while RDVNP has a loss rate of 20 packets per second. DWARF-Net was recommended to researchers based on the simulation study and results of this effort.
