1. A method comprising:
in a first computing node, generating a multicast communication, wherein the multicast communication uses a multicast internet protocol (IP) address as a destination IP address;
in the first computing node, associating the multicast communication with a flow;
in the first computing node, communicating the multicast communication to a second computing node;
in the first computing node, receiving a second communication from the second computing node, wherein the second communication uses a second IP address associated with the second computing node as a source IP address;
in the first computing node, determining whether the second communication is received within a timeout period associated with the multicast communication;
in the first computing node and when the second communication is received within the timeout period associated with the multicast communication, associating the second communication with the flow; and
in the first computing node and when the second communication is not received within the timeout period associated with the multicast communication, associating the second communication with a second flow.
