A method includes dividing, at a cable modem termination system, a transmit stream into multiple data streams. The multiple data streams include a first data stream and a second data stream. Each of the multiple data streams has a lower bit rate than a bit rate of the transmit stream. The method includes transmitting, via the cable modem termination system, the first data stream over at least a first channel of a group of channels. The method also includes transmitting, via the cable modem termination system, the second data stream over at least a second channel of the group of channels. The group of channels supports traffic to a plurality of destinations. The first channel and the second channel are frequency-division multiplexed channels.

Data service including channel group

A domain name server request is received from a local domain name server. Operational performance parameters of a web host and a first content distribution network are received. Aggregate operational performance parameters of a second content distribution network are received. A first record is sent to the local domain name server that indicates the domain name server request is to be handled by the web host on a condition that a performance value is below a predetermined operational performance level threshold. A second record is sent to the local domain name server that indicates the domain name server request is to be handled by the first or the second content distribution network on a condition that the performance value is equal to or above the predetermined operational performance level threshold.

Unified web hosting and content distribution

A method at a cable modem termination system includes dividing a transmit stream into multiple data streams and transmitting the multiple data streams over multiple radio frequency channels of a group of channels. The group of channels supports traffic to a plurality of destinations. Each channel in the group of channels is a downstream channel.

Operational performance parameters of a web host and a first content distribution network are monitored. Capacity and health statistics of a second content distribution network are received. A determination is made whether a customer request is to be served by the first content distribution network or the second content distribution network based on a performance threshold. Usage of a primary service provider, the web host, the first content distribution network, and the second content distribution network are tracked.

A system and method are disclosed for the repair of IP multicast sessions. A repair server polls multiple transmit servers to accumulate as many of the packets missing from the multicast session as possible. A network includes a source of multicast packets in a multicast session and a plurality of multicast recipients in that session. A repair server in the network provides the packets it receives to the recipients. The repair server includes a missing packet detector. There is a plurality of retransmit servers in the network buffering portions of the packets they respectively receive during the session. The repair server maintains an ordered list of the retransmit servers that are most likely to have buffered copies of packets missing from the session. When the repair server detects that there are packets missing from the session it has received, it uses the ordered list to sequentially request the missing packets from respective ones of the plurality of retransmit servers.

Network-based service for the repair of IP multicast sessions

A service model, integrated system, and method for enabling a service provider to deliver an integrated web hosting and content distribution service offering, which affords assured operational performance service levels, regardless of whether the customer's web site is served by the service provider's hosting center, the service provider's content distribution network (CDN), by a third party web host, or by a third party CDN. A monitoring system of the primary service provider receives detailed capacity and health statistics from any CDN under the operational control of the primary service provider, receives aggregate capacity and health statistics from other CDNs not under the operational control of the primary service provider. A redirection system then decides to which web host, content distribution network, or combination thereof, user requests for content are directed in order that operational performance service levels are maintained.

Unified web hosting and content distribution system and method for assuring predetermined performance levels

A method includes receiving, at a transmit site, a first stream of packets addressed to an end user device in a first address space. The first stream of packets is encapsulated to form a second stream of packets addressed in a second address space. A first packet of the second stream of packets is assigned to a first radio frequency channel of a plurality of radio frequency channels. A second packet of the second stream of packets is assigned to a second radio frequency channel of the plurality of radio frequency channels. The first packet is transmitted via the first radio frequency channel and, in parallel, the second packet is transmitted via the second radio frequency channel.

Devices and methods to communicate data streams

A system for monitoring quality of calls in a network. A server receives information concerning calls which begin or end in a network and at the same time receives measurements of a quality parameter such as bandwidth. This measurement data is provided by a probe, so that the server is able to correlate calls which are placed through the network with the quality of service in the network at that time. When the quality falls below a desired level, the server notifies the customer or the network operator so that appropriate action may be taken.

Call tracking using voice quality measurement probe

The present invention is directed to mechanisms for content-aware redirection and content exchange/content discovery that permit a request for content to be redirected to a particular advantageous server that can serve the content.

Method for content-aware redirection and content renaming

A receive device includes a plurality of demodulators and a tunnel destination. The demodulators are configured to receive multiple data streams, each of the multiple data streams having a bit rate that is lower than a bit rate of a transmit data stream. The tunnel destination is configured to recombine the multiple data streams to provide a receive data stream having a bit rate equal to the bit rate of the transmit data stream. At least one of multiple radio frequency channels is connected to a legacy user between a transmit site and the receive device.

Receive device for a cable data service

A method of sending data from a transmit site to a receive device includes dividing a first transmit data stream having a first bit rate into multiple data streams with each of the multiple data streams having a bit rate that is lower than the first bit rate. Each of the multiple data streams is transmitted over a cable network having multiple radio frequency channels. The multiple data streams are recombined at the receive device to provide a receive data stream having a bit rate equal to the first bit rate. A second transmit data stream is transmitted over one of the radio frequency channels to a legacy user connected to the one radio frequency channel between the transmit site and the receive device.
