Facilitating multicast traffic collision reduction

摘要

The reduction of multicast traffic collisions is facilitated. A device that is associated with a multicast group receives a multicast message requesting re-transmission of an acknowledgment message from the device. The multicast message includes information identifying the device within the multicast group of devices. In response to the device being determined to be identified by the information, the acknowledgement message can be re-transmitted after a defined transmit delay period after receipt of the multicast message. The defined transmit delay period can be based on the number of devices in the multicast group, based on the number of previous re-transmissions by the device and/or based on the number of devices for which re-transmission is requested.

主权项

1. An apparatus, comprising:
a processor; and a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
receiving, by the apparatus, a multicast message that comprises information:
identifying the apparatus within a multicast group of apparatuses; andrepresenting a request for re-transmission of an acknowledgement message; andin response to a determination that the apparatus is identified by the information, transmitting the acknowledgement message after a defined transmit delay period from the receiving, wherein the defined transmit delay period is a function of a defined back off period, wherein a back off index value of the defined back off period is incremented by a first defined value based on a number of re-transmissions by the apparatus and is decremented by a second defined value for every acknowledgement message received from the apparatus, and wherein the defined back off period is determined as a function of a back off adjustment value and an initial back off period computed based on a randomly-generated number.
