Abstract
A particular overall architecture for transmission over a bonded channel system consisting of two interconnected MoCA (Multimedia over Coax Alliance) 2.0 SoCs (Systems on a Chip) and a method and apparatus for the case of a “bonded” channel network. With a bonded channel network, the data is divided into two segments, the first of which is transported over a primary channel and the second of which is transported over a secondary channel.
Claims20
A method for bonded channels, the method comprising:
- determining the number of symbols needed to carry data over two bonded channels according to:
- a number of bits per Orthogonal Frequency Division Multiplexing (OFDM) symbol for the two channels;
- a number of parity bits per Low Density Parity Check (LDPC) codeword;
- a respective maximum LDPC codeword payload size from Error Vector Magnitude (EVM) reports for each channel;
- and
- a bonded channel frame splitting overhead.
A network node for utilization in a communication network, the network node operable to determine a number of symbols needed to carry data to be transmitted over at least two bonded channel, the network node comprising:
- at least one module operable to at least:
- determine the number of symbols needed to carry data to be transmitted over the two bonded channels based, at least in part, on:
- a number of bits per Orthogonal Frequency Division Multiplexing (OFDM) symbol for the at least two channels;
- a number of parity bits per Low Density Parity Check (LDPC) codeword;
- a respective maximum LDPC codeword payload sizes from Error Vector Magnitude (EVM) reports for each channel;
- and
- a bonded channel frame splitting overhead.
