  2. OCP SAI Switching ASICs (SDKs) do not have any common API. • Same feature (for e.g. Routing Table) has different styles. • Same underlying construct (for e.g. ACL) has different semantics. SAI addresses above issue, and offers a C API that’s common across ASICs. Identifies the switching abstraction, express it as {object, attribute:value} Open API, is extensible for newer abstractions and programmable ASICs. SAI does not deal with specifying user-APIs or defining user-models. Note that many of these user-APIs end up using overlapping hardware abstractions. • Thus, SAI is a way to express hardware/ASIC constructs in an abstracted fashion, and provide a unified API across plethora of silicons/platforms. SAI is an open initiative (https://github.com/opencomputeproject/OCP-Networking-Project- Community-Contributions/tree/master/sai/inc ). OCP-compliant platform will have SAI driver.
