Emulating circuit switching in Ethernet using an Ethernet circuit header

摘要

A device for emulating circuit switching in Ethernet using an Ethernet circuit header (ECH) includes a node of a network that is configured to receive a packet. A control module may be configured to determine that a destination address portion of a data frame associated with the packet matches a predefined format. A parser module may be configured to parse an ECH portion of the destination address to identify a circuit-identification (ID). A look-up module may be configured to look up the circuit ID in a circuit-ID table using at least one of a plurality of key options to generate a look-up-result data. The control module may be configured to use the look-up-result data to direct the packet to a destination interface of a destination node.

1. A method for emulating circuit switching, the method comprising:
receiving, at a node of a network, an Ethernet packet; determining that a destination address portion of a data frame associated with the Ethernet packet matches a predefined format; parsing an Ethernet circuit header (ECH) portion of the destination address to identify a circuit identification (ID), wherein the ECH portion of the destination address further includes a multicast bit and ECH priority bits; looking up the circuit ID in a circuit-ID table using at least one of a plurality of key options to generate a look-up-result data; and using the look-up-result data to direct the packet to a destination interface of a destination node.
