Auto tuning of hybrid WAN links by adaptive duplication of packets on alternate links
Embodiments of the present disclosure describe a system and method for dynamically duplicating network packets onto a reliable link. Network devices can be connected by a primary link and by a secondary link.

Time aware path computation
A path computation method involves receiving (200) a request for computation of a new path in the network, the request indicating a future time interval when the path is desired. Subsequently a future network status is generated (210, 212, 214), having a representation of availability of path resources at the future time interval, based on selected paths already reserved at that future time interval. Then there is a step of computing (220) which of the path resources to select for the new path according to the future network status. By generating this future network status when the future time interval is known, it can be generated in respect of a limited time interval rather than covering all possible future reservable times. Thus the benefits of time aware path computation can be achieved without the need for maintaining a huge database of availability at all future times, of all the path resources. |

Cell voltage accumulation discharge
Methods, systems, and devices for cell voltage accumulation discharge are described. One or more sections of a bank of ferroelectric memory cells may be coupled with one or more access lines. By activating one or more switching components, one or more sections (that may include a memory array and/or a driver) of memory cells may be isolated. When isolated, a voltage may be applied across an access line associated with the section to activate an access device of each memory cell. By activating a switching component of a respective memory cell, a capacitor of the memory cell may be discharged and then the isolated section may be coupled with the plurality of access lines. |

Parallel access for memory subarrays
Techniques herein may allow a row of a subarray in a bank of a memory device to be activated before a precharge operation has been completed for a previously opened row of memory cells in the same bank. Each subarray within the bank may be associated with a respective local latching circuit, which may be used to maintain phases at the subarray independent of subsequent commands to the same bank. For example, the latching circuit may internalize timing signals triggered by a precharge command for a first row such that if an activation command is received for a different subarray in the same bank at a time before the precharge operation of the first row is complete, the precharge operation may continue until the first row is closed, as the timing signals triggered by the precharge command may be maintained locally at the subarray using the latching circuit. |
