20090248878 | AGGREGATING CONNECTION MAINTENANCE TO OPTIMIZE RESOURCE CONSUMPTION - Combining network connection maintenance operations that use a resource to extend battery life. Each of the network connections has a timer and a defined tolerance for early connection maintenance. After receiving notification of an event, the network connections are accessed to identify the connections for which a maintenance operation may be performed early based on the timer and the tolerance. In an embodiment, the maintenance operation includes sending a transmission control protocol (TCP) keep-alive packet on the connection. | 10-01-2009 |
20090260052 | Inter-Process Message Security - An inter-process messaging security management may be provided. A message comprising an operation to be performed may be sent from a process operating in a process chamber to a second process operating in another chamber. Before the message is allowed to be delivered, the validity of the operation contained in the message may be verified and a security policy may be examined to determine whether the message is permitted to be sent from the first process to the second process. If the security policy permits the second process to execute the operation requested by the first process, the message may be delivered to the second process. If the operation is not permitted, the message may not be delivered and an error message may be returned to the first process. | 10-15-2009 |

After receiving notification of an event, the network connections are accessed to identify the connections for which a maintenance operation may be performed early based on the timer and the tolerance. In an embodiment, the maintenance operation includes sending a transmission control protocol (TCP) keep-alive packet on the connection. | 04-12-2012 |
20130198435 | MEMORY PAGE EVICTION PRIORITY IN MOBILE COMPUTING DEVICES - Eviction priority technologies provide for the prioritized eviction of memory pages from a first memory, such as a DRAM, in a mobile computing device that have been copied from a second memory, such as flash memory. Eviction priority is based on eviction costs for the memory pages. The eviction cost for a page is based on page-in costs, page-out costs, the priority of a process associated with the page, page access probability and combinations thereof. Page-in costs include read costs, fixup costs and decompression costs, and page-out costs include write-back costs and compression costs. Page lists allow for the sorting of pages by page type (e.g., read only, read/write) and can be used to keep track of eviction costs. Pages are evicted from the first memory in order of increasing eviction cost. | 08-01-2013 |
