Adapted physical-layer transmission properties based on packet stream

A communication system comprising:

• a transmitting device coupled to a communications channel between the transmitting device and a receiving device, the transmitting device configured to:
• for at least a first packet of a packet stream to be transmitted from the transmitting device to the receiving device, determine physical layer transmission properties for the communications channel based at least in part upon an upper layer protocol field included in the first packet, and
• transmit the first packet of the packet stream to the receiving device using the determined physical layer transmission properties;
• and
• the receiving device coupled to the communications channel, the receiving device configured to receive the first packet of the packet stream using the determined physical layer transmission properties.

A method comprising:

• for at least a first packet of a packet stream to be transmitted from a first device to a second device via a hybrid network:
• determining, at the first device, a physical layer tone map for a communications channel of the hybrid network, the physical layer tone map based at least in part upon an upper layer protocol field included in the first packet;
• and
• transmitting at least the first packet of the packet stream to the second device using the determined physical layer tone map.

A method comprising:

• receiving, from a first device at a second device, first packets associated with a first portion of a packet stream, the first packets received using a first set of physical layer transmission properties;
• determining, at the second device, a second set of physical layer transmission properties for use with subsequent packets of the packet stream, the physical layer transmission properties based, at least in part, upon a type of data in the first packets;
• communicating the second set of physical layer transmission properties to the first device;
• and
• receiving second packets associated with a second portion the packet stream using the second set of physical layer transmission properties.

A non-transitory computer readable medium storing computer program code, the computer program code comprising instructions which when executed by a processor of a hybrid device cause the hybrid device to:

• for at least a first packet of a packet stream to be transmitted from a first device to a second device via a hybrid network:
• determine, at the first device, a physical layer tone map for a communications channel of the hybrid network, the physical layer tone map based at least in part upon an upper layer protocol field included in the first packet;
• and
• transmit at least the first packet of the packet stream to the second device using the determined physical layer tone map.
