Services mobility in storage systems
While providing a storage service to a client system, a storage system maintains a complete set of storage service metadata for the service on the same storage device that stores the user data received from the client system. When an event is detected that requires the storage service to be moved to a new storage system, the storage service can be moved to a new storage system by moving the storage device containing both the user data and the storage service metadata to the new storage system. The new storage system detects the storage device that has been moved, and detects the storage service metadata and user data. The new storage system then uses the storage service metadata and user data from the storage device to immediately reestablish the storage service with the client system, without having to perform a separate step of copying the storage service metadata from the previous storage system.

Random next iteration for data update management
Host machines and other devices performing synchronized operations can be dispersed across multiple racks in a data center to provide additional buffer capacity and to reduce the likelihood of congestion. The level of dispersion can depend on factors such as the level of oversubscription, as it can be undesirable in a highly connected network to push excessive host traffic into the aggregation fabric. As oversubscription levels increase, the amount of dispersion can be reduced and two or more host machines can be clustered on a given rack, or otherwise connected through the same edge switch. By clustering a portion of the machines, some of the host traffic can be redirected by the respective edge switch without entering the aggregation fabric. When provisioning hosts for a customer, application, or synchronized operation, for example, the levels of clustering and dispersion can be balanced to minimize the likelihood for congestion throughout the network.

Network folder synchronization
Synchronization of folders shared among multiple clients over a network is provided. A first user of a first client instantiates a folder to be shared, and the folder and its contents are synchronized with a host system. As the user makes changes to the folder and its contents on the first client, those changes are propagated to the synchronized version on the host server. Other clients who will be sharing the synchronized folder register with the host system and obtain a current version of the synchronized folder and contents. As the contents of the synchronized folder are changed by any of the clients, the changes are propagated to the host system, which in turn delivers the changes to each of the clients registered as sharing that folder. In this way, each client participating in the share has a current version of the folder and its contents.

What this does is to allow someone (e.g., content provider, network operator, etc.) to impose a strategy over those networks. Rather than having to construct solutions that deliver a particular kind of content, a particular security requirement, a particular latency requirement, etc., one can simply provision particular types of nodes as needed when needed.

Video stream network coding in information centric networks
The disclosure relates to technology for network coding a video stream in an information centric network. A network node breaks a media segment (e.g., a video segment) into chunks. The chunks for one media segment are then encoded into network encoded chunks, each of which may be a linear combination of the chunks for that media segment. Thus, a number of network encoded chunks for a media segment are generated. These network encoded chunks may be provided to a client in response to a request for content in an information centric network (ICN). When the client receives enough network encoded chunks, the client decodes them to produce the original chunks for that media segment. The client may perform bit-rate adaptation based on the time it takes to receive a media segment. The client may view the communication interfaces as a logical communication link upon which to perform rate adaptation.

Responsive to a determination that the element includes the predefined multi-bit element value, the encoding of the lead byte comprises setting the value indicator to a preconfigured indicator of the predefined multi-bit element value, the preconfigured indicator requiring fewer bits to represent than the predefined multi-bit element value. Responsive to a determination that the element does not include the predefined multi-bit element value, the encoding of the lead byte comprises setting the value indicator to a preconfigured value-follows indicator. The serializing additionally includes encoding an element-value bit stream when the value indicator is set to the preconfigured value-follows indicator.

The streams manager then interacts with the public cloud manager to move the selected portion(s) of the streaming application to the public cloud. By taking sensitive data into account, the streams manager protects the integrity of sensitive data while still taking advantage of the additional resources available in a public cloud.
