SAI

SAI API: The Switch Abstraction Interface (SAI) defines the API to provide a vendor-independent way of controlling forwarding elements, such as a switching ASIC, an NPU or a software switch in a uniform manner. Refer to [3] for more details on SAI API.

ASIC SDK: Hardware vendors are expected to provide a SAI-friendly implementation of the SDK required to drive their ASICs. This implementation is typically provided in the form of a dynamic-linked-library which hooks up to a driving process (syncd in this case) responsible of driving its execution.
