Abstract

See full text

At a first virtual device executing in a data processing system, a determination is made whether a partner list associated with the first virtual device includes a threshold number of partner virtual devices, the first virtual device participating in the control cluster. A first Live packet is unicast over the VLAN to each partner virtual device identified in the partner list. A unicast of a second Live packet from a second virtual device to the first virtual device is received over the VLAN, the second virtual device being identified in the partner list. A Hello packet is broadcast over the VLAN to cause the Hello packet to reach a third virtual device, wherein the Hello packet is configured to discover a new partner virtual device to add to the partner list, discovering the new partner enlarging the control cluster.
