Abstract
A method and a device are provided for managing, in a receiving entity, data packets received from a transport layer connection established with a transmitting entity. The connection includes at least one stream in connected mode and at least one stream in non-connected mode. The management method includes transmitting, by the receiving entity, a so-called return message, relating to at least one data packet from one of the two streams in connected mode or in non-connected mode of the connection, the return message being transmitted to the transmitting entity on the other stream of the connection.
Claims4
A method for managing data packets in a receiving entity, wherein the method comprises:
- receiving the data packets from a transport layer connection set up with a sending entity, wherein the connection comprises at least one transmission control protocol (TCP) stream and at least one stream in connectionless mode, the stream in connectionless mode being of unidirectional multicast Internet protocol (IP) type with an ECN capable transport (ECT) bit activated in IP headers of the packets of the stream,
- sending, by the receiving entity, a message, termed a return message, relating to at least one data packet from the stream in connectionless mode of the connection, the return message being sent to the sending entity on the TCP stream of the connection, the return message being related to the stream in connectionless mode and comprising an explicit congestion notification (ECN)-Echo flag.
A device for managing, in a receiving entity, data packets received from a connection set up with a sending entity, comprising:
- a processor;
- and
- a non-transitory computer-readable medium comprising instructions stored thereon, which when executed by the processor configure the device to implement:
- a first sending/receiving module configured to send and receive a transmission control protocol (TCP) stream;
- and
- a second sending/receiving module configured to send and receive a stream in connectionless mode,
- wherein the connection comprises at least one TCP stream and at least one stream in connectionless mode, the stream in connectionless mode being of unidirectional multicast Internet protocol (IP) type with an ECN capable transport (ECT) bit activated in IP headers of the packets of the stream, and
- wherein the first sending/receiving module sends a message, termed a return message, relating to at least one data packet received by the second sending/receiving module, the return message being related to the stream in connectionless mode and comprising an explicit congestion notification (ECN)-Echo flag.
A non-transitory computer-readable recording medium comprising instructions stored thereon, which when executed by a processor of a receiving entity configure the receiving entity to:
- receive data packets from a transport layer connection set up with a sending entity, wherein the connection comprises at least one transmission control protocol (TCP) stream and at least one stream in connectionless mode, the stream in connectionless mode being of unidirectional multicast Internet protocol (IP) type with an ECN capable transport (ECT) bit activated in IP headers of the packets of the stream, and
- sending, by the receiving entity, a message, termed a return message, relating to at least one data packet from the stream in connectionless mode of the connection, the return message being sent to the sending entity on the TCP stream of the connection, the return message being related to the stream in connectionless mode and comprising an explicit congestion notification (ECN)-Echo flag.
