Constructing a network enabling layer-2 interconnection of data centers
First Claim
1. An edge device to connect a first data center to at least one other data center, the edge device comprising:
- an interface; and
a processor to;
send, via the interface, information of the first data center to a neighbor server to register the first data center;
obtain, via the interface, information of a registered data center from the neighbor server, wherein the information of the registered data center comprises a Media Access Control (MAC) address of the registered data center;
determine whether the MAC address of the registered data center is identical to the MAC address of the first data center;
if the MAC address of the registered data center is different from the MAC address of the first data center, generate a virtual bridge port for the registered data center to communicate with the first data center.

Abstract
A method for constructing a network enabling layer-2 interconnection of data centers includes: a current data center registers at a neighbor server when the current data center gets online, obtains information of all registered data centers, generates a virtual bridge port for each registered data center; after the current data center comes online, the current data center obtains information of all newly registered data centers according to a pre-set rule, generates a virtual bridge port for each newly registered data center; establishes a tunnel to each registered data center by using the virtual bridge port corresponding to the registered data center, and transmit data via the tunnel.

5. A non-transitory computer readable medium storing machine readable instructions executable by a processor to:
-
register information of a first data center with a neighbor server; obtain information of a second data center from the neighbor server, wherein the second data center is registered with the neighbor server; generate a virtual bridge port for the second data center to communicate with the first data center via a layer-2 interconnection; send a resolution request to the second data center; set a state of the virtual bridge port to be UP if a resolution response is received from the second data center; and set the state of the virtual bridge port to be DOWN if the resolution request is not received after a predetermined number of resolution requests are sent to the second data center. - View Dependent Claims (6, 7, 8, 9, 10)

11. A non-transitory computer readable medium storing machine readable instructions executable by a processor to:
-
register information of a first data center with a neighbor server; obtain information of a second data center from the neighbor server, wherein the second data center is registered with the neighbor server; generate, on an edge device of the first data center, a virtual bridge port for the second data center to communicate with the first data center via a layer-2 interconnection in a core network; and in response to receiving a broadcast Ethernet packet on an internal Ethernet port of the edge device, cause the edge device to flood the broadcast Ethernet packet to all ports of the edge device including the virtual bridge port, and perform tunnel encapsulation on the Ethernet packet flooded to the virtual bridge port before transmitting the encapsulated packet into the core network by unicasting. - View Dependent Claims (12)

13. An edge device to connect a first data center to at least one other data center via a core network, the edge device comprising:
-
an interface; and a processor to determine an address of a second edge device of a second data center and establish a layer-2 interconnection with the second edge device via the interface without relying on multicasting in the core network. - View Dependent Claims (14, 15)
