Abstract
A Multicast-Broadcast over a Single Frequency Network (MBSFN) message may be multicasted to a cluster of network elements. Using multicasting or unicasting based on a number of unacknowledged network elements of the cluster of network elements, the MBSFN message may be retransmitted to unacknowledged network elements in the cluster of network elements, subsequent to a time period to receive an acknowledgement message from a first and a second network element.
Claims10
A networking device comprising:
- a processor, of the networking device, configured to:
- multicast, over an interface to a group of network elements, a Multicast-Broadcast over a Single Frequency Network (MBSFN) message;
- receive at least two acknowledgement messages from the group of network elements;
- and
- retransmit, by multicasting or unicasting based on a number of network elements of the group of network elements, the MBSFN message to network elements in the group of network elements from which no acknowledgment is received, wherein the retransmission is after a time period to receive an acknowledgement message from a first and a second network element.

A method performed by a networking device, the method comprising:
- multicasting, by the networking device over an interface to a group of network elements, a Multicast-Broadcast over a Single Frequency Network (MBSFN) message;
- receiving, by the networking device, at least two acknowledgement messages from the group of network elements;
- and
- retransmitting, by the networking device by multicasting or unicasting based on a number of unacknowledged network elements of the group of network elements, the MBSFN message to network elements in the group of network elements from which no acknowledgment is received, wherein the retransmitting is after a time period to receive an acknowledgement message from a first and a second network element.
