Abstract
A method of transmitting packets of data in a communication network comprising at least first to third stations, the method comprising the steps of sending a first number of the data packets from the first station to a second station; identifying which of the first number of packets are correctly received by the second station from the first station; and sending a second number of data packets from the third station to said second station commencing with the packet identified as being required after the last correctly received packet received form the first station.
Claims47
A method comprising:
- transmitting data packets from a common node to first and third stations;
- receiving at said common node an acknowledgement forwarded to the common node by one of first and second nodes;
- and
- advising the other of the first and second nodes that said acknowledgment has been received,
- wherein said first station is in communication with said first node, said third station is in communication with said second node, said first and second nodes are in communication with said common node, and said third station is configured to send data packets to a second station commencing with a packet identified as being required after a last correctly received packet received at the second station from the first station.
A system, comprising:
- first, second and third stations, wherein said first station is configured to send a first number of data packets to the second station, the second station is configured to identify which of the first number of packets it receives from the first station, and the third station is configured to send a second number of data packets to the second station commencing with a data packet identified as being required after a last correctly received packet from the first station;
- a first node in communication with said first station;
- a second node in communication with said third station;
- and
- a common node in communication with said first and second nodes, wherein an acknowledgement is forwarded to the common node by one of said first and second nodes, and the common node is configured to advise the other of the first and second nodes that said acknowledgement has been received.
An apparatus, comprising:
- a transmitter configured to transmit data packets from the apparatus to first and third stations;
- a receiver configured to receive at the apparatus an acknowledgement forwarded from one of first and second nodes;
- and
- a controller configured to advise the other of the first and second nodes that said acknowledgment has been received,
- wherein said first node is in communication with said first station, said second node is in communication with said third station, said first and second nodes are in communication with said apparatus, and said third station is configured to send data packets to a second station commencing with a packet identified as being required after a last correctly received packet received at the second station from the first station.
