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.

Facilitating multicast traffic collision reduction

Aspects of the subject disclosure may include, for example, a method that includes presenting a media content item at a communication device coupled to a network, and analyzing the media content item to determine a current desired cache size and to predict a future desired cache size for presentation of the media content item; the desired cache size varies during the presentation in accordance with properties of the media content item. The method further includes adjusting a cache of the communication device in accordance with the analyzing. Other embodiments are disclosed.

Predictive cached buffer for communication devices

A distance between a host communication device and a mobile target communication device at multiple times over a time period based on a received signal emitted by the mobile target communication device. An amount of time that the distance between the host communication device and the mobile target communication device is within a distance threshold is also determined. A determination is further made whether the amount of time the distance between the host communication device and the mobile target communication device is within the distance threshold is less than a predetermined amount of time. If the amount of time that the distance between the host communication device and the mobile target communication device is within the distance threshold is less than the predetermined amount of time, transmission of a notification to a third party is initiated via a gateway.
