Abstract:
1. A method for learning a Medium Access Control (MAC) address, applied in an edge device in an interconnection network of data centers, said method comprising: based on a receipt of a request message from a first node to a second node, creating by the edge device a session cache item, wherein the session cache item includes: an Internet Protocol (IP) address of the second node, an IP address of the first node, and a first relationship between a MAC address of the first node and a first port of the edge device through which the request message was received; based on a receipt of a response message from the second node to the first node, updating, by the edge device, the session cache item having the IP address of the first node and the IP address of the second node, wherein the updated session cache item further includes a second relationship between a MAC address of the second node and a second port of the edge device through which the response message was received; and providing the first relationship and the second relationship to a data plane of the edge device to facilitate data packet forwarding between the first node and the second node.
