Layer 2 packet switching without look-up table for ethernet switches

摘要

In one embodiment, a method for assigning a media access control (MAC) address includes receiving a request from a device for a MAC address at a port of a switching device, determining a MAC address to assign to the device based at least partially on the port, and responding to the request with the MAC address. In another embodiment, a method for retrieving a media access control (MAC) address includes sending a request for a MAC address to a MAC allocation server (MAAS), waiting a predetermined amount of time to receive a response to the request, wherein the response comprises the MAC address, and using the MAC address when the response to the request is received within the predetermined amount of time. Other systems, methods, and computer program products are presented according to more embodiments.

主权项

1. A method for assigning a media access control (MAC) address, the method comprising:
applying a hashing algorithm to a plurality of MAC addresses that are available to be assigned to obtain a plurality of hash values; a hardware processor correlating one or more unique hash values to each port of a switching device; receiving a request from a device connected to the switching device for a MAC address at a first port of the switching device; the hardware processor determining a MAC address from the plurality of MAC addresses to assign to the device based at least partially on the first port on which the request was received from the device and the one or more hash values associated with the first port; and responding to the request with the determined MAC address.
