P4BID: information flow control in p4
Karuna Grewal, Loris D’Antoni, Justin Hsu · 2022
Modern programmable network switches can implement custom applications using efficient packet processing hardware, and the programming language P4 provides high-level constructs to program such switches. The increase in speed and programmability has inspired research in dataplane programming, where many complex functionalities, e.g., key-value stores and load balancers, can be implemented entirely in network switches. However, dataplane programs may suffer from novel security errors that are not traditionally found in network switches.
