| + | * Edgecore | ||
| + | * Accton | ||
| + | * Alpha Networks | ||
| + | * Penguin computing | ||
| + | * NVIDIA> | ||
| + | |||
| + | These are vendors that nornmally run directly on ODM machines (besides from the incumbent ones): | ||
| + | - ipinfusion | ||
| + | - mikrotec | ||
| + | - cumulus | ||
| + | - SONIC (Software for Open Network in the Cloud. Azure uses it) | ||
| + | |||
| + | Note that **ODM (Original Design Manufacturing)** vs OEM (Original Equipment Manufacturer): | ||
| + | - OEM or the Original Equipment Manufacturer designs a product based on the buyer’s specifications. | ||
| + | - ODM or the Original Design Manufacturer designs and manufactures products on their own. | ||

| + | Openswitch: uses db model instead of ephemeral message bus.\\ | ||
| + | Hardware: Acton switches [[http:// | ||
| + | Current ASICs: | ||
| + | - Broadcom | ||
| + | - [[https:// | ||
| + | - Trident : more for Enterprise | ||
