A method and system for network capacity planning are provided. The method includes: collecting utilization data related to a plurality of network resources on the network; determining a peak period for each of the network resources based on the utilization data; determining at least one key performance indicator (KPI) over the peak period for each of the network resources; aggregating each of the KPIs for each of the plurality of network resources; and outputting the aggregated KPIs. The system includes a data source module configured to collect utilization data related to a plurality of network resources; a peak period module configured to determine a peak period for each of the network resources based on the utilization data; a peak KPI module configured to determine at least one KPI over the peak period for each of the plurality of network resources; a KPI aggregation module configured to aggregate the KPIs for each of the network resources; and a processor module configured to output the aggregated KPIs.

A method and system for analyzing devices on a network are provided. The method includes: receiving at least one packet from a Customer Premises Equipment (CPE); determining identity metadata associated with the at least one packet; and analyzing the at least one packet to determine a device associated with the at least one packet. The system for analyzing devices on a network includes: a packet processor configured to receive at least one packet from a CPE; a subscriber/session identity module configured to determine identity metadata with the at least one packet; and a device tracker module configured to analyze the at least one packet to determine a device associated with the at least one packet.

A method and system for managing bitrate of network traffic are provided. The method for managing bitrate of network traffic includes: receiving a packet; retrieving metadata from the packet and associating the packet with at least one traffic aggregate; determining a drop rate for the at least one traffic aggregate based on network flow data; and determining, based on the drop rate and the metadata, to forward or drop the packet. The system includes a packet processing module configured to receive a packet; a deep packet inspection module configured to retrieve metadata from the packet and associate at least on traffic aggregate with the packet; a control module configured to determine a drop rate for the at least one traffic aggregate based on network flow data; and a policy decision module configure to determine whether to forward or drop the packet based on the drop rate and the metadata of the packet.

A method for measuring quality of experience for media streaming in a network is provided, the method includes: identifying a media stream; detecting an event related to the media stream indicative of a quality of experience (QoE) as perceived by a subscriber; measuring a metric relating to the detected event; and determining a quality of experience measurement based on the metric. A system for measuring quality of experience for media streaming as perceived by subscribers in a network is provided, the system having: a media flow recognition module configured to identify a media stream; a QoE event handler operatively connected to the media flow recognition module and configured to detect an event related to the media stream indicative of a quality of experience as perceived by a subscriber; a metric measurement module operatively connected to the QoE event handler and configured to measure a metric relating to the detected event; and a quality of experience calculation module operatively connected to the metric measurement module and configured to determine a quality of experience measurement based on the metric.

A network data flow management device including: a working packet module configured to store data related to a data flow; at least one network interface connected to the working packet module for receiving and sending data related to data flows; and a processor configured to: receive data from the working packet module and determine if the data flow matches a predetermined protocol; and if the data flow matches the predetermined protocol, send predictive acknowledgments based on the data flow via the network interface. A method for network data flow management including: monitoring a data flow for a predetermined protocol; if the data flow matches the predetermined protocol, saving data relating to the data flow; and creating and sending a predictive acknowledgement packet related to the data flow.

The present invention is directed to a system and method for administering Peer to Peer (P2P) query messages within a P2P network. The present invention collects a plurality of metrics for each host that it is aware of in a P2P network, most often by a host information or query hit message. The metrics collected aid in determining a set of P2P hosts best able to fulfill a query message, without having knowledge of specific content. The metrics collected also aid in managing query messages in that they determine when to drop query messages or when to resend query messages.
