Abstract: An apparatus includes a memory and one or more processors. The one or more processors are configured to receive a first computing task for execution, and, during execution of the first computing task (i) to monitor Operating System (OS) calls issued by the first computing task, (ii) to identify, based on the monitored OS calls, one or more outputs produced by the first computing task, and (iii) and to store the one or more outputs of the first computing task in the memory. The one or more processors are further configured to receive a second computing task for execution, and, upon ascertaining that the second computing task will produce at least one output that is identical to a stored output of the first computing task, to reuse the stored output of the first computing task as an output or the second computing task.

Abstract: A method for communication includes accepting in an Access Point (AP) data items for transmission over a wireless channel to multiple terminals served by the AP. Aggregate airtimes, which were previously allocated to the respective terminals on the wireless channel, are assessed. Transmission of the data items is scheduled depending on the aggregate airtimes.

Abstract: A method for communication includes receiving Transport Control Protocol (TCP) data packets from a first TCP endpoint, for forwarding over a Wireless Local-Area Network (WLAN) to a second TCP endpoint. The received TCP data packets are cached in a cache memory. The TCP data packets cached in the cache memory are forwarded over the WLAN to the second TCP endpoint, including retrying to forward one or more of the cached TCP data packets independently of the first TCP endpoint.
