Abstract: A message may be too long to be sent all at once. For example, there may be a limit on the number of bits that can be transmitted by a device operating in a power-save mode. The disclosure relates in some aspects to sending a message over packet boundaries (e.g., several frames or sub-frames). The disclosure relates in some aspects to segmenting a Broadcast Information Block and sending the resulting segments over broadcast information window boundaries. In some aspects, this information may be sent via overhead channels. To facilitate this segmentation, information about the segmentation may be included in the information sent from the transmitter to the receiver. For example, a first segment may indicate the number of segments and subsequent segments may indicate the segment number.

Abstract: An apparatus in one embodiment comprises a first host device comprising a processor coupled to a memory. The first host device is configured to assign to additional host devices different portions of a source logical unit designated for migration to a target logical unit. In conjunction with migration of the assigned portions of the source logical unit to the target logical unit by the additional host devices, the first host device is configured to receive from the additional host devices respective sets of information each characterizing one or more writes directed to the corresponding assigned portion during the migration. The first host device is further configured to update the target logical unit based at least in part on the received sets of information. In some embodiments, the first host device is configured to assign to itself a portion of the source logical unit designated for migration to the target logical unit.

Abstract: Disclosed herein are methods, systems, and processes to provide coherency across disjoint caches in clustered environments. It is determined whether a data object is owned by an owner node, where the owner node is one of multiple nodes of a cluster. If the owner node for the data object is identified by the determining, a request is sent to the owner node for the data object. However, if the owner node for the data object is not identified by the determining, selects a node in the cluster is selected as the owner node, and the request for the data object is sent to the owner node.

Abstract: The disclosed computer-implemented method for maintaining cache coherency may include (1) receiving an indication of a revocation of a grant to an owner node of a shared lock for a data object owned by the owner node, (2) invalidating, in response to the indication, a copy of the object in a local cache of the owner node, (3) releasing, in response to the indication, the grant of the shared lock, (4) receiving, after the releasing of the grant, a request from the requesting node to update the object in the cache, (5) transmitting, in response to the request to update the object, a request for a shared lock for the object, (6) receiving an indication of a grant of the shared lock, and (7) updating, in response to the grant of the shared lock, the object in the cache. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: The disclosure relates in some aspects to location reporting and paging for satellite communication. In one aspect, the disclosure relates to a user terminal (UT) sending a message to report information about the UT's location. A threshold may be used to control whether (e.g., when) the UT reports its location. The location information may be used to enforce area (e.g., country) restrictions for the UT. In one aspect, the disclosure relates to forwarding paging messages between network access controllers. For example, a network access controller that is not able to page a UT may forward a paging message to another network access controller. In one aspect, the disclosure relates to a list of paging areas that indicates where a UT need not perform a paging area update.

Abstract: An apparatus comprises a host device configured to communicate over a network with a storage system. The host device comprises a plurality of nodes each comprising a plurality of processing devices and at least one communication adapter. The host device comprises a multi-path input-output (MPIO) driver that is configured to obtain an input-output (IO) operation that targets a given logical volume. The MPIO driver identifies a source node and a plurality of paths between the source node and the given logical volume. The MPIO driver determines a load factor and a distance for each identified path. The MPIO driver determines a weight associated with each identified path based at least in part on the determined load factor and distance and selects a target path based at least in part on the determined weight. The MPIO driver delivers the obtained IO operation to the given logical volume via the selected target path.

Abstract: An online system enables content providers to efficiently create and publish sponsored content in multiple phases. Each phase of the content creation is represented by a draft of the content. Multiple drafts of the content are stored in a repository of the online system for optimizing content delivery and publication, such as quick identification of conflicts in a draft based on analysis of draft fragments of the draft. Objects associated with the sponsored content are stored in an object model, including a key-value table. The connections amongst the various draft segments of a draft are stored in a hierarchy structure, e.g., a tree structure. Each user associated with a draft has a role, such as an owner or a collaborator, where all of the roles can contribute to the draft. The online system efficiently publishes the drafts of the sponsored content and presents the sponsored content to its target users.

Abstract: The disclosure relates in some aspects to enabling a user terminal (UT) to obtain information about nearby cells and any beams generated by nearby cells. For example, a network can send a neighbor cell list to UTs, where the list identifies the cells in that neighborhood and provides information about any beams generated by those cells. Thus, a UT can learn the neighboring beams/cells that the UT can reselect to if the current beam/cell becomes weak. In some aspects, the UE can learn the attitude (e.g., pitch, roll, yaw, or any combination thereof) profile of neighboring satellites as well as the pointing angles and the ON-OFF schedules of their beams. In some aspects, the UT can learn a start angle and a span for a satellite and use this information to identify a satellite the UT can reselect to if the current beam/cell becomes weak.
