A method and apparatus to monitor quality of service (QoS) of wireless mobile devices is described. In one embodiment, the present invention provides a method to monitor QoS performance of one or more services provided to a mobile user. The method includes comparing the performance of at least one service provided to the mobile user against at least one QoS threshold value. In one aspect, the present invention detects and determines responses to services having performance levels that cross at least one associated QoS threshold value. In one aspect, QoS thresholds may be associated with QoS between a mobile device and network. In another aspect, QoS thresholds may be associated with the performance level of mobile device operation services such as hardware and software operations. In one embodiment, when a performance level of a service associated with a mobile device crosses at least one QoS threshold, the affected mobile device process data associated with such service performance. Such processed data may then be provided to a user, network personnel, and third parties, etc. for processing thereof.

A customer premises device is provided for monitoring quality of service (QOS) metrics between a network edge and a customer. The device includes a memory which stores at least one user profile, and, information regarding active sessions of traffic flow through the customer premises device. A hardware and/or software/firmware based controller monitors traffic flow between the customer and the network edge and receives requests for new active sessions. The processor accesses the at least one user profile stored in memory to identify a policy hierarchy with respect to active sessions of traffic flow upon receipt of a request to establish a new active session. The processor selects a candidate active session to be terminated based upon the policy hierarchy and terminates the selected session in accordance with information stored in memory regarding the selected session. In this manner, the processor enforces quality of service, for both upstream and downstream sessions, based upon the policy hierarchy of the user profile.

A method of audio (as defined herein) transmission over a network where audio frames are sent in UDP packets, wherein the audio frames are overlapped by at least one for each UDP packet. A method of monitoring quality of service information, and a packet for this, are also disclosed.

A packet switch identifies a communication flow carried across an IP network, observes the communication flow, and acquires statistics data thereof, such as the number of packets that passed through the switch, the number of discarded packets, time at which the packets arrived at the switch, and time at which the packets were sent out from the switch. The packet switch continues to acquire the statistics data on the communication flow while the communication flow continues. If the packet switch performs a relay function, it sends the locally obtained statistics data to the adjoining packet switch placed downstream. If the packet switch is a node placed on either end edge of the network, it gathers the statistics data obtained by and delivered from other switches in the network and sends the gathered statistics data to the network management system.

A system and method for providing end-to-end security of content over a heterogeneous distribution chain is provided. A content owner provides content to an aggregator that receives the content and processes the content. The processing may involve decrypting the content and associating at least one of a unique fingerprint and a watermark to the decrypted content. The unique fingerprint and a watermark to the decrypted content provide identifying characteristics to the content. Additional content-based fingerprints may be used to monitor quality of consumer experience for Video and Audio. The content may be sent in a decrypted state to a client or in an encrypted state. When the content is encrypted the aggregator wraps and encrypts the content with a signature such that an end-to-end flow of the content may be determined. Application Level encryption is used to provide network/distribution medium transparency as well as persistent encryption. When the content is transmitted from a consumer to another consumer the transmitting consumer loses rights to the content.

An optical signal quality monitoring system is provided, by which the quality of optical signals can be examined using a single monitoring system, not depending on the bit rate of each signal. In the system, an optical signal having a bit rate N.f0, that is, N times as much as basic clock frequency f0, is sampled by using a pulse repetition frequency f0/n1-DELTAf or f0/n1+DELTAf where n1 is a predetermined natural number and the pulse repetition frequency slightly differs from f0/n1 by DELTAf, and an amplitude histogram of the optical signal is determined based on results of the sampling. Regarding the sampling points which constitute the histogram, a set of higher-level points and a set of lower-level points are extracted and a ratio of a difference between an average level of the set of higher-level points within a predetermined period and an average level of the set of lower-level points within a predetermined period, to the sum of standard deviations of both sets within each predetermined period is calculated as a coefficient of the S/N, and the quality of the optical signal is examined based on the coefficient. By performing optical sampling, quality of optical signals having bit rates of a few dozen Gbit/s or more can be monitored.

The present disclosure describes a method for monitoring the quality of service of H.264 multimedia communications. The present disclosure achieves the in-band QoS monitoring of the H.264 multimedia communications, thereby reducing extra overhead introduced by the QoS monitoring. The present disclosure makes direct use of the extension message mechanism of the high level media protocol H.264 per se to bear QoS report information without use of any extra channel, so as to achieve an “in-band” QoS report mechanism. The H.264 message extended mechanism, e.g., an SEI message, is used to self-define user data for transmission of the QoS report to monitor a transmission quality of the H.264 multimedia communications, without influence upon communications of any existing device in the H.264 protocol while reducing extra bandwidth overhead. Various protection measures are also provided based upon the use of the H.264 in-band report to improve the reliability of the RTCP/UDP.
