Abstract
Example embodiments provide apparatus, systems and methods to optimise a multicasting operation used to transmit data packets in a communication network.
Claims20
An apparatus comprising:
- a data store to store at least one variable parameter associated with a multicasting operation;
- a communication module to:
- multicast a data packet to a plurality of nodes in a communication network using the stored variable parameter;
- and
- receive, from a node of the plurality of nodes, a retransmitted version of the multicast data packet, the retransmitted data packet comprising feedback data;
- and
- at least one processor coupled to the data store and the communication module to:
- determine, using the feedback data, that the variable parameter requires modification to optimise the multicasting operation for the network;
- modify the variable parameter in response to the feedback data;
- and
- store the modified variable parameter in the data store.

An apparatus for retransmitting data packets, the apparatus comprising:
- at least one processor;
- and
- a communication module, coupled to the at least one processor, to:
- receive a first multicast data packet from a source apparatus in a communication network;
- modify the first multicast data packet by adding feedback data to the first multicast data packet, the feedback data specifying that at least one variable parameter associated with a multicasting operation used to send the first multicast data packet requires modification to optimise the multicasting operation for the network;
- and
- retransmit the modified first multicast data packet.
4 more elements
The apparatus as claimed in 17 wherein if the further multicast data packet comprises identification data, the communication module retransmits the further multicast data packet.
A method of optimising a multicasting operation, the method comprising:
- multicasting a data packet to a plurality of nodes in a communication network using a multicasting operation and at least one variable parameter associated with the multicasting operation;
- receiving, from a node of the plurality of nodes, a retransmitted version of the multicast data packet, the retransmitted data packet comprising feedback data;
- determining, using the feedback data, that the variable parameter requires modification to optimise the multicasting operation for the network;
- modifying the variable parameter in response to the feedback data;
- and
- storing the modified variable parameter.
