Abstract: A load balancing algorithm and cluster configuration details are stored at each of a set of namespace nodes of a cluster hosting a deduplicated file system. Upon a client connecting to a namespace node, a server-initiated communication channel is established between the namespace node and the client over which updates to the load balancing algorithm, cluster configuration details, or both are sent. The load balancing algorithm and cluster configuration details are sent to the client, thereby allowing the client to determine according to the load balancing algorithm and cluster configuration details, which particular namespace node should handle a particular file system operation. Thereafter, each connected client is immediately notified of changes to the cluster such as node or service additions or deletions or software upgrades to the cluster so that each client can use the updated information to conduct load balancing.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a user equipment (UE) may transmit, to a network entity, a capability message indicating a capability of the UE to report a cyclic shift for a reference signal. The UE may receive an indication of a reporting configuration from the network entity indicating uplink resources for reporting the cyclic shift by the UE, and the UE may receive one or more reference signals from the network entity. In some examples, the UE may transmit, to the network entity and using the uplink resources, an uplink message indicating the cyclic shift. The UE may estimate the cyclic shift based on measuring a channel delay spread of the one or more reference signals, a phase noise mask of the one or more reference signals, or both.

Abstract: In example embodiments, techniques are described for using workspace databases to provide workspace resources to customize sessions of applications. File-based workspace databases are maintained in workspace files in a local file system. Cloud-based workspace databases are maintained in a cloud-based blob storage container of a storage account of a cloud storage system. Each cloud-based blob storage container may hold multiple cloud-based workspace databases, including multiple versions of the same database. To use a cloud-based workspace database, a backend module of an application may create an in-memory cloud container object that represents a connection to the cloud-based blob storage container. It may be attached to an in-memory object configured to manage a local cache of blocks of workspace databases. Access to the cloud-based blob storage container may be managed by access tokens provided by a container authority.

It may execute one or more database commands to modify the block in the cloud cache, and change an identifier of the block in a local copy of a manifest that includes a list of the blocks of the cloud-based blob storage container. It may further upload the modified block and the local copy of the manifest to the cloud-based blob storage container, wherein the uploaded local copy of the manifest replaces the manifest in the cloud-based blob storage container.

Abstract: Embodiments of the invention relate to methods and systems for efficiently sharing assets such as files and folders between a host computer system and a client computer system while minimizing the amount of work the client must perform to efficiently transfer an asset. In one or more embodiments, assets such as files and folders that are to be shared or transferred are placed in appropriate network slice queues by the hosts rather than the clients. These network slice queues allow the files and folders to be placed in slices without utilizing the resources of the clients as well as much of the available network resources. This ensures efficient use of network resources, while minimizing the amount of work the hosts and/or clients must perform in order to perform a backup.

Abstract: Examples herein describe systems and methods for self-healing in a Telco network function virtualization cloud. KPI attributes for virtual network functions can be mapped to physical fault notifications to create synthesized alerts. The synthesized alerts can include information from both a virtual and physical layer, allowing a self-healing action framework to determine root causes of problems in the Telco cloud. Remedial actions can then be performed in either the virtual or physical layer of the Telco cloud. Remedial actions in one layer can be based on root causes identified in the other, which can allow for remediation before network downtime occurs.
