LEADER DEVICE SELECTION IN CONTROL CLUSTERS USING SHARED VLAN

摘要

A method for leader device selection in a control cluster using a shared virtual local area network (VLAN) is provided in the illustrative embodiments. A broadcast Hello packet is received from a sender virtual device over the VLAN at a first virtual device. When the first virtual device satisfies a partnership criterion specified in the Hello packet, a first ranking of the first virtual device is evaluated to be higher than a ranking of a sender virtual device. A first Live packet is unicast over the VLAN to the sender virtual device and a leadership role in the control cluster is taken by the first virtual device. The sender virtual device is caused to stop a broadcasting operation at the sender virtual device. A second Hello packet is broadcasted from the first virtual device over the VLAN.

主权项

1. A method for leader device selection in a control cluster using a shared virtual local area network (VLAN), the method comprising:
receiving over the VLAN, at a first virtual device executing in a data processing system, a broadcast Hello packet; evaluating, at the first virtual device, and responsive to the first virtual device satisfying a partnership criterion specified in the Hello packet, that a first ranking of the first virtual device is higher than a ranking of a sender virtual device, the sender virtual device broadcasting the Hello packet; unicasting over the VLAN a first Live packet to the sender virtual device; taking, by the first virtual device, a leadership role in the control cluster, the first virtual device and the sender virtual device being partners in the control cluster; causing the sender virtual device to stop a broadcasting operation at the sender virtual device; and broadcasting, from the first virtual device, a second Hello packet over the VLAN.
