摘要： A method and system for dynamic bandwidth re-allocation is provided. The method includes the steps of monitoring a video streams delivered by a server to a first client and a second client that have a same service level agreement and determining whether the first client is receiving a lower bitrate video stream compared to the second client. The method further includes the step of adjusting a parameter to allow the first client to receive a higher bitrate video stream. In an example, the monitoring, determining and adjusting steps are performed by a cable modem termination system (CMTS). In another example, the monitoring, determining and adjusting steps are performed by an optical line terminal (OLT).

摘要： 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.

摘要： A method, system and computer program product to schedule transmissions in a two-tier network are provided. In an example, the system includes a Data Over Cable Service Interface Specification (DOCSIS) scheduler configured to generate a MAP message to allocate bandwidth and a first instance in time to a cable modem to transmit data to a branch node. The system further includes a MAP message translator coupled to the DOCSIS scheduler and configured to determine a second instance in time at which data from the cable modem arrives at the branch node and generate a GATE message that grants the branch node bandwidth to transmit the data received from the cable modem at the second instance in time to a headend node.

摘要： A system and method for allowing flexible associations between PHY devices and MAC devices in a point-to-multipoint communications system, such that a given upstream channel is not deterministically bound to a particular MAC device. An upstream MAC device may connect to a varying number of PHY devices depending on configured PHY capacity. Upstream service flows are intact by noting Service identifiers (SIDs) of each burst received at a PHY device, A burst is then directed via a switching infrastructure to the appropriate MAC on the basis of the SID.

摘要： A method, system, and computer program product for receiving and resequencing a plurality of data segments received on a plurality of channels of a bonding channel set, comprising determining if a sequence number of a received segment matches an expected sequence number. If so, the process includes forwarding the segment for further processing, incrementing the expected sequence number; and forwarding any queued packets corresponding to the expected sequence number and immediately succeeding sequence numbers less than a sequence number of annexed missing segment. If the sequence number of the received segment does not match the expected sequence number, the received segment is queued at a memory location. The address of this location is converted to a segment index. The segment index is stored in a sparse array.
