Performance Analysis of Raspberry Pi-based Testbed Development for P4 Programmable Data Plane

The development of information technology in various fields makes the network bigger and more complex. The software-defined network appears as a solution that changes the paradigm of the network management problem by separating the data plane and controller centrally on the control plane. Currently, SDN comes with a programmable data plane with the P4 language which is more flexible than OpenFlow as a link between the data plane and the control plane. The Raspberry Pi-based testbed for P4 programmable data plane is a platform for testing the performance of the data plane and P4 programs before being implemented in production. This project analyzes the performance of the Raspberry Pi-based testbed by measuring several network parameters such as delay, throughput, jitter, and packet loss using several test scenarios. Based on the experiment results, the amount of packet processing in each scenario affects the delay parameter. Small jitter parameters indicate a stable delay during the experiment. CPU performance has huge impact to the testbed performance and can be seen in the throughput and packet loss test results using different values of bandwidth, buffer length, and room temperature.
