A method of providing information regarding an ethernet frame, within the ethernet preamble of the ethernet frame, comprises inserting into the ethernet preamble an inter-line-card header that includes a start control character, a version number, a parity bit, a source port, a destination port, and a forwarding domain entry; and preserving said inter-line-card header, inside of said ethernet preamble, in a media access control (mac) sub-layer in said ethernet frame. The method may include a step of selecting the decoding format for the inter-line-card header corresponding to the version number and/or forwarding other ethernet frames according to additional forwarding information provided by the forwarding domain entry.

Low voltage feedforward current assist ethernet line driver
Described examples include ethernet physical layer (phy) interface integrated circuits with transmit interface circuitry for transmitting data to an ethernet network through a magnetic interface, which includes a voltage mode first amplifier with an output that generates a first voltage signal from a supply voltage according to a data input signal. The transmit interface circuit also includes a feedforward second amplifier circuit with an output stage that operates in a first mode to generate a current signal from the supply voltage according to the first voltage signal and to provide the current signal to the first amplifier output to boost a peak voltage at the output above the supply voltage to facilitate support for higher peak signal voltage swings for 10base-t applications while using 2.5 volt or other low voltage supply levels..

Scalable virutal networks in sdn-based ethernet networks using vlans
Various embodiments relate to a method, device, and machine-readable storage medium including: instructions for receiving a configuration request from an edge device, wherein the configuration request identifies a traffic flow between at least two end devices other than the edge device; instructions for assigning a virtual local area network (vlan) identifier to the traffic flow; instructions for configuring the edge device to add the assigned vlan identifier to outgoing frames associated with the traffic flow, wherein the outgoing frames are frames that will be transmitted by the edge device to a core network. Various embodiments additionally include instructions for configuring, in response to assigning the vlan identifier, at least one additional edge device to remove the vlan identifier from incoming frames associated with the traffic flow, wherein the incoming frames are frames that have traversed at least one core node of the core network..
