Abstract: A computerized method of delivering popular content of a service delivery apparatus (SDA) in an asymmetrical network topology. The method comprises receiving a first acquisition request for content from a user node (UN) over an upstream data link, the request comprising at least a content identification (CID). An instruction is sent to the UN to redirect content requests to the SDA. A second acquisition request is sent from the SDA to a content source (CS) for the content requested by the first acquisition request, upon determination that the downstream data link between the UN and the CS is inaccessible to the SDA, the request including at least the CID. The content is received by the SDA from the CS. The received content from the SDA is sent to the UN.

Finally, the content provider provides a local address of the local caching server to the electronic device, wherein the local address is used by the electronic device to obtain the content from the local caching server and the LAN without accessing a content delivery network (CDN) outside the LAN.

Abstract: Upstream burst transmit times are dynamically communicated to the transmit unit in grants issued over time and in any order. A critical parameter is when to trigger the operation to order the buffered data stream for transmission. If the ordering operation is triggered too soon, a later grant of an earlier burst transmit time may not be accounted for and the subsequent transmission could violate the transmission order rule. If the ordering operation is triggered too late, the decision to transmit a burst at an earlier burst transmit time may violate the margin rule. To address these concerns, a fetch offset time in advance of each granted burst transmit time is assigned. As each fetch offset time is sequentially reached, a next partial data portion of the buffered data stream is prepared for burst communication.

Abstract: A system and method for improved upstream data transmission. In an embodiment, a cable modem includes a transceiver configured for transmitting data upstream once permission is granted. In between times when permission to transmit is granted, however, the cable modem is configured to prepare as much data as possible for immediate upstream transmission once that very permission is granted. Thus, prior to permission being granted, the cable modem assembles (pre-processes) the data into transmit frames such that the data frames may be stored in a local memory coupled to the transceiver in a “ready-to-go” format. In this manner, the entire amount of time/bandwidth allocated to the cable modem in response to its request for upstream data transmission may be dedicated to actually transmitting data upstream as opposed to consuming time and bandwidth processing the data into data frames after upstream data transmission has been granted.
