Abstract: A software-defined network controller includes at least one processor and memory storing computer-executable instructions coupled to the at least one processor. The at least one processor is configured to execute the computer-executable instructions to cause the software-defined network controller to monitor performance characteristics of a machine learning trust manager, and evaluate the performance characteristics to determine whether the machine learning trust manager satisfies a performance threshold. In response to determining that the machine learning trust manager fails to satisfy the performance threshold, the processor deactivates the machine learning trust manager, and activates a deterministic trust manager in place of the machine learning trust manager.

Abstract: A server includes a field programmable gate array (FPGA) partitioned into a set of partial reconfiguration (PR) slots and a memory that supports a set of logical buffers. A deterministic application request module (DARM) receives application requests to allocate the set of reconfiguration slots to one or more tenants and the one or more tenants configure the allocated reconfiguration slot to perform tasks. The DARM stores data associated with the application request in a first logical buffer from the set of logical buffers. A reconfiguration slot scheduling (RSS) module identifies a first reconfiguration slot from the set of reconfiguration slots and associates the first reconfiguration slot with the first logical buffer. A reconfiguration slot initialization (RSI) module reconfigures the first reconfiguration slot to perform the tasks based on the data stored in the first logical buffer.
