Abstract:
1. A method comprising: selecting, at a source node, destination nodes to each receive a request message; setting an unresolved indicator for each of the selected destination nodes in a request message descriptor, wherein the unresolved indicator indicates which destination nodes to send a request message to; sending a number of request messages to the selected destination nodes indicated as unresolved; clearing the unresolved indicator for each selected destination node in the request message descriptor when a response message indicating acceptance of the request message is received from each selected destination node; setting a stop indicator associated with a selected destination node that refuses to receive the request message sent to the selected destination node, wherein the stop indicator causes the destination node to refuse subsequent request messages received until the destination node receives a restart indicator; in response to a destination node of the selected destination nodes refusing the request message and receiving a number of response messages equal to the number of request messages sent, resending the request message with the restart indicator to the destination node, wherein the restart indicator indicates to the destination node to unset the stop indicator and restart a stream associated with the request message.
