A cable modem that supports stateless requesting and/or limited contention-based requesting is provided herein. In an example, a physical layer (PHY) configured to communicate over a plurality of upstream channels is provided. A bandwidth requester is provided to request bandwidth using contention-based requesting over a first subset of the upstream channels for contention-based flows and request bandwidth using stateless requesting over a second subset of the upstream channels for stateless flows.

Solutions for upstream channel bonding

A cable modem termination system (CMTS) is disclosed that allocates one or more minislots of a super-frame arrangement to cable modems for upstream transmission. The super-frame arrangement includes multiple minislots that correspond to multiple communication channels of one or more super-frames. The CMTS receives requests for upstream bandwidth from the cable modems. The CMTS continuously allocates the minislots of the super-frame to provide upstream bandwidth grants to accommodate these requests. The CMTS communicates the upstream bandwidth grants as a single upstream bandwidth allocation map (MAP) to the cable modems.

Convergence layer bonding over multiple carriers

A system and method is provided for interleaving data in a communication device. The system includes a memory that stores blocks of data to be interleaved. In addition to the memory, the system includes a write module and a read module, each of which is coupled to the memory. The write module is configured to receive a burst of data and write blocks of data from the burst into the memory. The write module is also configured to provide control information to the read logic. The control information includes a rolling burst counter and a burst profile bank identifier for each block. If interleaving is activated, the control information also includes information pertaining to how the read module should interleave the block. If interleaving is not activated, the control information also includes the byte length size of the burst. The read module reads blocks of data from memory in either an interleaved fashion or a non-interleaved fashion in accordance with the control information. A block available signal and a block out signal is also provided to determine when a block of data is available to be read from the memory.

System and method for interleaving data in a communication device

Requests are processed to transmit data packets upstream from a cable modem to a cable headend in a manner that minimizes the use of CPU operations and/or memory capacity. Data packets to be transmitted upstream are stored at the cable modem. The data packets each have a given transmission data byte length value. Burst profiles are received successively at the cable modem. Each time a new bust profile is received, a set of physical data length values corresponding to respective transmission data byte length values is calculated from the parameters of the received burst profile. The calculated set of physical data length values is stored in memory so the individual values can be retrieved from the transmission data byte length values again and again, rather than being re-calculated each time a conversion is made from transmission data byte length values to physical data length values. The same set of physical data length values is used until a new burst profile is received by the cable modem.
