摘要： A method is provided in one example and includes determining that an access concentrator has lost customer premise equipment information. The method also includes obtaining the customer premise equipment information that is lost by evaluating Neighbor Discovery data and dynamic host configuration protocol version six (DHCPv6) query data. In more specific implementations, the method may include communicating a Bulk Leasequery message; receiving a response to the Bulk Leasequery message; and filtering out cable modem identifiers from the response to the Bulk Leasequery message.

摘要： In one example, a Cable Modem Termination System (CMTS) determines target Radio Frequency (RF) bandwidth amounts for Data Over Cable System Interface Specification (DOCSIS) bonding groups according to the DOCSIS priority of active flows within the bonding groups. The CMTS then tunes bandwidth allocation amongst the DOCSIS bonding groups according to the target bandwidth amounts. The target bandwidth amounts can be recalculated at intervals, and the bandwidth allocation re-tuned at the intervals, to account for changes in flow activity or DOCSIS priority assignment.

摘要： A system includes a forwarding engine to schedule when replicas of a received multicast packet are forwarded towards one or more multicast recipients. The system also includes an egress interface device to replicate the multicast packet and forward the multicast packet replica towards the one or more multicast recipients when prompted by the forwarding engine based on the scheduling.

摘要： In one example, a bandwidth allocation device allocates physical channel bandwidth between local interfaces. Thereafter, at a polling time, the bandwidth allocation device determines whether there is communication activity between each local interface and the physical channel. The bandwidth allocation device can then dynamically reallocate the physical channel bandwidth at the polling time according to the communication activity determinations.
