The use of servers themselves to forward/route packets provides higher flexibility, reduced costs, and lower energy consumption in data center networks. However, the association of a new task to the servers can lead to a reduction in their performance, and consequently, impair the performance of the network itself. This paper investigates experimentally the basic process of forwarding packets servers. In this paper, parameters such as throughput, latency and packet loss will be analyzed in order to identify the best implementation strategy among the following switching alternatives: Circuits, Bursts and packets. As a tool for conducting experiments Click Modular Router is employed; as well as native kernel forwarding/routing. For performance parameters monitoring Oflops+NetFPGA is employed. A key finding is that with an efficient method for packet classification, the model of bursts, and routing via Linux Kernel show themselves as better options in the implementation of network-centric datacenter servers, since they combine higher throughput with lower CPU consumption
