Abstract: The present invention discloses an overlay switch (OSW) and a method used by the same. A received unicast packet needs to pass a waypoint chain including a number of waypoints. A network address of a first waypoint of the waypoint chain and an underlay network address of a second OSW connected to the first waypoint are obtained. In response to a determination that the second OSW is not the first OSW the unicast packet is encapsulated into a first underlay network packet according to a specification of an overlay network. A field of a destination header of the first underlay network packet includes the underlay network address of the second OSW. The first underlay network packet is sent to the second OSW.

A field of a destination header of the first underlay network packet includes the underlay network address of the second OSW. A source port field of a user datagram protocol (UDP) header is set to indicate a waypoint index included in a corresponding waypoint chain. The first underlay network packet is sent to the second OSW.

Abstract: Methods, computer program products, and systems are presented. The methods include, for instance: locating, by one or more processor, at least one virtual machine within a virtual network, wherein gratuitous address resolution functionality of the at least one virtual machine is inactive; and providing, by the one or more processor, location information of the at least one virtual machine. In one embodiment, the locating comprises: receiving an IP address of the at least one virtual machine; and selecting a virtual machine hosting network device from a computing network node table, where the computing network node table comprises at least one network connection record of the silent virtual machine network device hosting a silent virtual machine having a known MAC address and an unknown IP address; and querying the silent virtual machine network device for a MAC address corresponding to the IP address of the at least one virtual machine.
