Abstract
A first protocol stack for communication on a first physical line is implemented. At least parts of a second protocol stack for communication on a second physical line are implemented. The first protocol stack and the second protocol stack are bonded at the Physical Medium Dependent layer of the first protocol stack and the Physical Medium Dependent layer of the second protocol stack (172). In some scenarios, the bonding may be at an upper edge of the Physical Medium Dependent layer, i.e., at the δ interface.
Claims19
A method of bonding physical lines at a modem, the method comprising:
- implementing a first protocol stack for communication on a first physical line,
- implementing at least parts of a second protocol stack for communication on a second physical line,
- bonding the first protocol stack and the second protocol stack at the Physical Medium Dependent layer of the first protocol stack and at the Physical Medium Dependent layer of the second protocol stack, wherein said bonding comprises:
- receiving messages from an upper layer of the first protocol stack above the Physical Medium Dependent layer, the messages comprising at least one of a payload section, a management section, and a combined payload and management section,
- distributing the messages between the first protocol stack and the second protocol stack,
- wherein said distributing comprises splitting at least some of the messages to distribute fractions of the messages between the first protocol stack and the second protocol stack.
