Methods of synchronizing sequence numbers of a number of devices of a network are disclosed. A method may include incrementing, at each of a first device and a second device of a network, a sequence number, wherein the sequence number is indicative of a number of frames generated at the associated device since the timing event. The method may also include inserting, at each of the first device and the second device, the sequence number into an associated frame. Related networks and devices are also disclosed.

A method of a service enabler architecture layer (SEAL) can include receiving a monitoring event subscription request for network connection status information at a network resource management server in the SEAL from a vertical application layer (VAL) server. The monitoring event subscription request can indicate a target VAL user equipment (UE), a type of the network connection status information, and a timeout period indicating an amount of time lapsed after the monitoring event subscription request was transmitted. The requested network connection status information is not transmitted after the timeout period. The network connection status information of the target VAL UE can be obtained from a wireless network system. A network connection status information response message can be transmitted from the network resource management server in the SEAL to the VAL server. The network connection status information response message can include the network connection status information of the target VAL UE.

A content reproduction system for reproducing content on a display device installed at a predetermined location in accordance with a predetermined reproduction schedule includes a user information acquiring circuit that acquires user information from a user terminal, a content acquiring circuit that acquires first content corresponding to the user information acquired by the user information acquiring circuit and a first reproduction schedule for reproducing the first content, and a display circuit that causes the user terminal to display the first content acquired by the content acquiring circuit, in accordance with the first reproduction schedule.

A method, computer program, and computer system are provided for asynchronous media request processing. Based on receiving a first function call requesting performance of a first function corresponding to a resource, a status code is returned, and the first function is performed. Then, after performance of the first function, based on receiving a second function call requesting updating of the resource corresponding to the first function, results of performing the first function are returned. In this manner, a response to the first function call is provided asynchronously based on receiving the second function call.

A method and apparatus for a first service processing system receiving and responding to a service request using a time context of a service time protocol is described. The method may include receiving a network based message associated with a service. The method may also include determining whether a service time context has been passed to the first service processing system from a second service processing system in the request. Furthermore, the method can include when no service time context is determined to have been passed to the first service processing system in the request, generating a current service time from a combination of a current physical time of the first service processing system and an initial counter time, performing a task associated with the service, and transmitting a second network based message that comprises the current service time as time context metadata associated with the performance of the task to a second service processing system.

A system and method for real-time discovery and monitoring of multidimensional topology models describing structural aspects of applications and of computing infrastructure used to execute those applications is disclosed. Different types of agents are deployed to the monitored application execution infrastructure dedicated to capture specific topological aspects of the monitored system. Virtualization agents detect and monitor the virtualization structure of virtualized hardware used in the execution infrastructure, operating system agents deployed to individual operating systems monitor resource utilization, performance and communication of processes executed by the operating system and transaction agents deployed to processes participating in the execution of transactions, providing end-to-end transaction trace and monitoring data describing individual transaction executions. The monitoring and tracing data of the deployed agents contains correlation data that allows to create a topology model of the monitored system that integrates transaction execution, process execution and communication and virtualization related aspects.
