Ddsa.rst5 This document describes the **Distributed Switch Architecture (DSA)** subsystem
22 An Ethernet switch typically comprises multiple front-panel ports and one
23 or more CPU or management ports. The DSA subsystem currently relies on the
27 gateways, or even top-of-rack switches. This host Ethernet controller will
28 be later referred to as "conduit" and "cpu" in DSA terminology and code.
30 The D in DSA stands for Distributed, because the subsystem has been designed
33 ports are referred to as "dsa" ports in DSA terminology and code. A collection
36 For each front-panel port, DSA creates specialized network devices which are
37 used as controlling and data-flowing endpoints for use by the Linux networking
39 interfaces in DSA terminology and code.
