摘要： A system for resource provisioning for content delivery of multiple services is disclosed. The system may be configured to offer multiple services, wherein at least one first offered service is delivery of prerecorded content and at least one second offered service is content delivered according to a deadline. In at least one embodiment, the first offered service may be video content, and the second offered service may be broadcast television content. The system may also be configured to deliver at least a portion of the first offered service in advance of use of that portion of the first offered service such that resource demand in connection with delivery of service content of the second offered service at peak delivery may be reduced. As such, fewer resources are needed to provide uninterrupted service of the first and second offered services.

摘要： A system and method for full-duplex communications provided by modifying the Media Access Control sub-layer of communication node protocols. The modification allows communication nodes to communicate with one another in full-duplex, where each node transmits and receives data simultaneously with other nodes in a single frequency. A timing of the simultaneous data transmissions, acknowledgments, and short-interframe-space waiting periods can be determined based on network-allocation-vector data transmitted in association with request-to-send or clear-to-send signals.
