Abstract: Techniques for embedding fabric addressing information within Ethernet media access control (MAC) addresses is disclosed herein and allows a multi-node fabric having potentially millions of nodes to feature Ethernet encapsulation without the necessity of a lookup or map to translate MAC addresses to fabric-routable local identifiers (LIDs). In particular, a locally-administered MAC address may be encoded with fabric addressing information including a LID. Thus a node may exchange Ethernet packets using a multi-node fabric by encapsulating each Ethernet packet with a destination MAC address corresponding to an intended destination. As the destination MAC address may implicitly map to a LID of the multi-node fabric, the node may use an extracted LID value therefrom to address a fabric-routable packet. To this end, a node may introduce a fabric-routable packet encapsulating an Ethernet packet onto a multi-node fabric without necessarily performing a lookup to map a MAC address to a corresponding LID.

Abstract: Examples include techniques for virtual Ethernet switching of a multi-node fabric. In some examples, first Ethernet links coupled with a group of Ethernet gateways are link aggregated. The group of Ethernet gateways couple with respective individual physical switch ports of a fabric switch of a multi-node fabric to form a default logical gateway to provide an uplink between a virtual Ethernet switch and an Ethernet network external to the multi-node fabric. Also, one or more individual Ethernet gateways coupled with respective individual physical switch ports of the fabric switch may be arranged to provide one or more respective downlinks between the virtual Ethernet switch and one or more Ethernet nodes external to the multi-node fabric via respective second Ethernet links coupled with the one or more individual Ethernet gateways.
