An Ethernet has its own importance and space in network subsystem. In today’s resource-intensive engineering the applications need to deal with the real time data processing, server virtualization, and high-volume data transactions. The real-time technologies such as video on demand and Voice over IP operations demand the network devices with efficient network data processing as well as better networking bandwidth. The performance is the major issues with the multi-port network devices. It requires the sufficient network bandwidth and CPU processing speed to process the real time data at the context. And this demand is goes on increasing. The new multi-port hardware technologies can help to improvements in the performance with the virtualized server environments. But, these hardware technologies having their own limitations in terms of CPU utilization levels and power consumption. It also impact on latency and the overall system cost. This thesis will provide the insights to some of the key configuration decisions at hardware as well as software designs in order to facilitate multi-port network devices performance improvement over the existing infrastructure. This thesis will also discuss the solutions such as Virtual LAN and balanced or symmetric network to reduce the cost and hardware dependency to improve the multi-port network system performance significantly over the current existing infrastructure. This performance improvement includes CPU utilization and bandwidth in the heavy network loads.
