摘要： Disclosed are techniques for dynamic allocation of multimedia server resources among multimedia transmission services of a service provider based on predicted resource usage by each multimedia transmission service. A predictive usage model of the utilization of server resources by one or more multimedia transmission services is generated for various combinations of operating characteristics, such as time of day, day of week, programming event or content, network status, and the like. The predictive usage model can be generated using past resource utilization characteristics of the multimedia transmission services from prior time periods having the same or similar characteristics. The service provider then can use the predictive usage model to more efficiently allocate multimedia server resources among the multimedia transmission services for upcoming time periods, which may be of fixed or variable duration.

摘要： A multicast test of an Internet Protocol (IP) network is performed with an initial multicast probing frequency. The multicast probing frequency of the multicast test is increased, and an impairment of the IP network based on the multicast test is detected based on the multicast test. Based on detecting the impairment, a unicast test is performed at one or more segments of the IP network. Based on the unicast test, an impaired segment of the IP network is identified.

摘要： A computer-implemented method includes receiving, at a monitoring center of a media distribution network, from a set top box device associated with a customer account, first error data indicating occurrence of a first error at the set top box device at a first time. The set top box device is at least partially functional after occurrence of the first error. The computer-implemented method includes receiving, at the monitoring center, second error data indicating occurrence of a second error at the set top box device at a second time. The set top box device is at least partially functional after occurrence of the second error. The computer-implemented method includes determining an elapsed time between the first time and the second time. The computer-implemented method includes automatically generating a trouble ticket indicating failure of the set top box device when the elapsed time satisfies a first threshold.

摘要： A system and method is disclosed for detecting distribution of multimedia content. The volume level of data traffic is monitored for a plurality of users to select any users with high-bandwidth usage. The time of day and the day of the week may be considered when determining whether a user is a high-bandwidth user. Upon selecting a user as one with high-bandwidth usage, such user may be subject to packet inspections of data traffic streams. In some embodiments, content identification parameters or watermarks are added to one or more packets in a data traffic stream carrying multimedia content.
