Apparatus and methods for managing the quality of experience of delivery of content to end-point or user devices. In one embodiment, metrics data pertaining to network conditions being experienced by consumer devices attached to a managed network are monitored by a network entity. The monitored metrics are analyzed to determine if a consumer device is experiencing poor network conditions, such as network congestion. A consumer device that is identified as experiencing poor network conditions is reported to a content delivery network (CDN) entity responsible for providing IP-based content. The CDN entity adjusts content delivery files used by the consumer device to request particular IP-based content and to select a version of the content suitable for delivery over consumer device's existing network condition. The adjustment may include for instance removing formats deemed unsupportable for delivery over the existing network condition or identify a default format for the consumer device to use.

Apparatus and methods for managing quality of experience during the delivery of content

A method including collecting, from a cable modem termination system (CMTS), counter data corresponding to usage of a network resource, wherein the counter data includes timestamp data, converting the counter data into timestamp normalized counter data by dividing the counter data among a plurality of buckets according to the timestamp data, and storing the timestamp normalized counter data.

Timestamp normalized counter data

A single measurement agent installed at an aggregation point in a network is cycled through multiple network segments (or service groups) using a switching device. Detailed broadband measurement tests are performed on each network segment.

Consumer devices that are identified as experiencing poor network conditions are reported to a content delivery network (CDN) entity responsible for providing IP-based content. The CDN entity adjusts content delivery files used by the consumer devices to request particular IP-based content to guide the consumer device to select a version of the content suitable for delivery over consumer device's existing network condition. The adjustment may include for instance removing formats deemed unsupportable for delivery over the existing network condition or identify a default format for the consumer device to use.

A system and method for detecting a transient outage of an Internet Protocol (IP) network. A probe sending device sends probe packets over the IP network. A probe packet includes a probe sequence number and a timestamp value issued by the probe sending device. A probe receiving device receives a current probe packet. The probe receiving device overwrites probe packet data obtained from a last received probe packet with the current probe packet when the current probe sequence number exceeds the sequence number of the last received probe packet by one. The probe receiving device stores the current probe packet data obtained from the current probe packet when the current probe sequence number exceeds the sequence number of the last received probe packet by more than one.
