A network node in a resource reservation network includes a data receiver, a transmitter and a timing adjustment requester. The data receiver receives fixed size application protocol data units (APDUs) from an application at fixed intervals. The transmitter transmits data from the network node to the network within transmission opportunities (TXOPs) associated with a constant data service flow for the application specified associated with the application and the network node in a media access plan (MAP) generated by a network scheduler. The timing adjustment requester requests adjustments of the network scheduler to the timing of TXOPs associated with the constant data service flow in order to minimize a delay between the arrival of the APDUs and their transmittal to the network.

A method, system and apparatus for server failure diagnosis and self-healing in a server farm. An autonomic server farm which has been configured in accordance with the inventive arrangements can include a multiplicity of servers enabled to respond to requests received from clients which are external to the server farm. A resource director such as an IP sprayer or a network dispatcher can be configured to route requests to selected ones of the servers, in accordance with resource allocation algorithms such as random, round-robin and least recently used. Significantly, unlike conventional server farms whose management of failure diagnosis and self-healing relies exclusively upon the capabilities of the resource director, in the present invention, client-assisted failure detection logic can be coupled to the resource director so as to provide client-assisted management of failure diagnosis and self-healing.

Techniques for network state-aware and network scheduling policy-aware task scheduling are provided. In one aspect, a method for scheduling tasks in a distributed computing network includes the steps of: collecting a pool of candidate resources in the distributed computing network for performing a given one of the tasks; predicting a performance of each of the candidate resources in performing the given task based on both i) a state and ii) a scheduling policy of the distributed computing network; and selecting a best candidate resource for the given task based on the performance. A system for scheduling tasks in a distributed computing network is also provided which includes a task scheduler; and a network scheduler, wherein the task scheduler is configured to schedule the tasks in the distributed computing network based on both i) the state and ii) the scheduling policy of the distributed computing network.

A media content packaging and distribution system that generates a plurality of disparate live media output streams to be viewed on a plurality of consumer devices, receives a programming schedule for a channel from a network scheduler. The programming schedule corresponds to at least a first manifest associated with a first pre-encoded media asset. Information related to a plurality of first media segments and one or more events from the first pre-encoded media asset indicated in the first manifest is inserted into a live output stream manifest at defined intervals. A disparate live media output stream, to be viewed by a consumer device for a channel via a media player, is generated based on the insertion of the information related to the plurality of first media segments from the first pre-encoded media asset indicated in the first manifest into the live output stream manifest.
