Abstract: Novel techniques are described for performing hierarchical key management involving an end-to-end file storage replication between different cloud infrastructure regions. The novel hierarchical key management comprises three different keys, a first security key for the source region, a session key, valid only for a session, for the transfer of data between two different regions, and a second security key for the target region. Novel techniques are also described for using different file keys for different files of a file system in each region.

Abstract: Techniques are described for efficient replication and maintaining snapshot data consistency during file storage replication between file systems in different cloud infrastructure regions. In certain embodiments, snapshot creation and deletion requests that occur during cross-region replications may be temporarily withheld until appropriate times to execute such requests safely, depending on the timing relationship between such requests and cross-region replication cycles.

Abstract: Techniques are described for efficient replication and maintaining snapshot data consistency during file storage replication between file systems in different cloud infrastructure regions.

Abstract: Techniques are described for partitioning B-tree keys of file systems into key ranges for parallel processing in delta generation during file storage replications between file systems in different cloud infrastructure regions. In certain embodiments, a delta generation processing for cross-region replication may utilize a key-range splitting mechanism involving a recursive algorithm that partitions B-tree keys of a source file system into roughly equal-size key ranges. All the partitioned key ranges may be processed in parallel and concurrently by different processing threads, one thread per key range, to improve the performance of the delta generation and achieve scalability.

Abstract: Techniques are described for ensuring end-to-end fair-share resource utilization during cross-region replication. In certain embodiments, a fair-share architecture is used for communication among pipeline stages performing a cross-region replication between different cloud infrastructure regions. Cross-region replication-related jobs are distributed evenly from a pipeline stage into a temporary buffer in the fair-share architecture, and then further distributed evenly form the fair-share architecture to parallel running threads of next pipeline stage for execute. Techniques for static and dynamic resource allocations are also disclosed.

Abstract: Techniques are described herein to enhance capability of floating level translators. For example, increased headroom is accomplished by adaptively bypassing the protection elements of the voltage level translator. In an example, a floating level translator can translate an input signal from a low-voltage domain to a high-voltage domain. A bypass circuit is coupled across the protection elements. The bypass circuit selectively engages during low-voltage operation (e.g., thereby providing a lower loss path relative to loss caused by the high-voltage protection elements and thus increasing the headroom swing), and disengages responsive to the high-voltage reference rail of the high-voltage domain exceeding a threshold or otherwise being high enough (e.g., greater than the potential of the low-voltage domain power rail). The bypass circuit can be implemented in a relatively low-complexity manner (e.g., back-to-back high-voltage FETs) without additional signals to control low-voltage capability.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a base station may recover a UE from a Msg3 failure during an RA procedure. During the RA procedure, the base station may transmit a RAR message to the UE and in response to the RAR message the UE may transmit an uplink message (e.g., Msg3) to the base station over a first resource indicated in the RAR message. If the base station fails to decode or receive the uplink message over the first resource, the base station may transmit a grant to the UE indicating a second resource for retransmitting the uplink message and the UE may retransmit uplink message to the base station according to the grant.

Abstract: An open radio access network (O-RAN) may include a control unit that communicates with a core network, a distributed unit that communicates with the control unit, a radio unit that communicates with the distributed unit and a user equipment (UE). Currently, the O-RAN may lack support for static configuration for a physical uplink shared channel (PUSCH) communication of message-A in a third generation partnership project (3GPP) two-step random access procedure.

The distributed unit may further transmit, in response to receiving the static configuration support indication, static configuration information to the radio unit, the static configuration information for receiving the payload data communicated via the message.
