Reducing size of multicast retry transactions

摘要

Disclosed are methods in which a source device that may multicast a message to a plurality of destination devices. The source device may receive an acknowledgement from less than all of the plurality of destination devices. Each acknowledgement may include an indication of the destination device from which the acknowledgement is received. A destination device may process the multicast message and generate an acknowledgement in response. In response to a time period subsequent to transmission of the multicast message, the source device may generate an updated message that indicates an acknowledgement status of each destination device associated with the group identifier from which an acknowledgement has been received.

主权项

1. A method comprising:
assigning a bit location in a bit field to each of a plurality of destination devices; multicasting, by a source device, a message to the plurality of destination devices, the message comprising a group identifier that identifies the plurality of destination devices; receiving acknowledgements from less than all of the plurality of destination devices, each acknowledgement including a bit value in the assigned bit location in the bit field for the destination device from which the acknowledgement is received; and after multicasting the message, generating, by the source device, an updated message that indicates an acknowledgement status of each of the plurality of destination devices, the updated message including the group identifier.
