Demo: P4Xtnd: P4 Programmability on Resource Constrained Environments with Extended Network Functionalities

We present P4Xtnd, which implements P4 programmability on resource-constrained devices with extended network functionalities for malicious device identification in IoT networks. Compared to existing methods, P4Xtnd operates in realtime and distributed manner for traffic collection, running ML at P4 Data plane with Federated Learning. Moreover, algorithms are proposed for trust assessment of sensor devices and dynamic network slicing for effective network management. With three LAN networks P4Xtnd shows its ability to detect malicious activities at higher accuracy.
