A method includes executing operations to generate a first enhancement function based on a parent-child link in a content hierarchy including a link between a parent node in a first level of the content hierarchy to a child node in a second level of the content hierarchy below the first level. A second enhancement function is generated based on a sibling link in the content hierarchy including a link between a sibling node in a third level of the content hierarchy and a sibling node in the third level of the content hierarchy sharing a common parent node with the first sibling node in a fourth level of the content hierarchy above the third level. A user content consumption metric is generated based on the first and second enhancement functions. A content list including a set of candidate content items ranked based on the user content consumption metric is generated.

A control device may be configured to form a network at a unique coordinated startup time. The control device may identify a role assigned to the control device in a previously-formed network that the control device was attached to. The control device may determine a unique coordinated startup time for the control device based on the role assigned to the control device in the previously-formed network. The control device may initiate a network formation procedure at the unique coordinated startup time for the device. For example, the network formation procedure may cause the control device to attach to another control device in the network. The network formation procedure is configured to enable the control device to assume the role assigned to the control device in the previously-formed network in the new network.

A network device includes a transmitter and a receiver to establish a secure connection with one or more network nodes as part of a Autonomic Control Plane (ACP) network. The network device also includes a processor coupled to the transmitter and receiver. The processor receives a request from an application to initiate a connection with a destination network node. The processor also receives packets from the application for transmission toward the destination network node. When the packets from the application are unencrypted, the processor end-to-end encrypts the unencrypted packets without notifying the application. The transmitter then transmits the encrypted packets towards the destination network node across the ACP network.

Some embodiments provide a hierarchical data service (HDS) that manages many resource clusters that are in a resource cluster hierarchy. In some embodiments, each resource cluster has its own cluster manager, and the cluster managers are in a cluster manager hierarchy that mimics the hierarchy of the resource clusters. In some embodiments, both the resource cluster hierarchy and the cluster manager hierarchy are tree structures, e.g., a directed acyclic graph (DAG) structure that has one root node with multiple other nodes in a hierarchy, with each other node having only one parent node and one or more possible child nodes.

In an embodiment of the present disclosure, a processor selects first and second policies of a plurality of policies enabled for enforcement in a cluster, each of the first and second policies comprising a set of rules and corresponding to a different set of operations performed in the cluster, wherein first and second sets of operations correspond to the first and second policies, respectively, and define, respectively, differing first and second policy types and, in response to determining that the first and second policies correspond to differing first and second policy types, merges the first and second policies into an aggregate policy to be enforced at a selected hierarchical level.

The present disclosure provides systems, methods, and computer readable storage devices for software distribution across a hierarchical network. A method includes sending, by a first node device, a registration request message to a second node device of a first distribution group of the hierarchical network. The registration request message indicates a request for the first node device to join the hierarchical network. The method further includes receiving, by the first node device, a registration response message from the second node device. The registration response message indicates an assignment of the first node device to a second distribution group corresponding to a tier that is below a tier that includes the first distribution group. The first node device may be authorized to perform peer-to-peer (P2P) communications to receive at least a portion of one or more files from node devices in the second distribution group or the second node device.

Some embodiments of the invention provide a method for processing requests for performing operations on resources in a software defined datacenter (SDDC). The resources are software-defined (SD) resources in some embodiments. The method initially receives a request to perform an operation with respect to a first resource in the SDDC. The method identifies a policy that matches (i.e., is applicable to) the received request for the first resource by comparing a set of attributes of the request with sets of attributes of a set of policies that place constraints on operations specified for resources. In some embodiments, several sets of attributes for several policies can be expressed for resources at different hierarchal resource levels of the SDDC. The method rejects the received request when the identified policy specifies that the requested operation violates a constraint on operations specified for the first resource.

Some embodiments provide a hierarchical data service (HDS) that manages many resource clusters that are in a resource cluster hierarchy. In some embodiments, each resource cluster has its own cluster manager, and the cluster managers are in a cluster manager hierarchy that mimics the hierarchy of the resource clusters. In some embodiments, both the resource cluster hierarchy and the cluster manager hierarchy are tree structures, e.g., a directed acyclic graph (DAG) structure that has one root node with multiple other nodes in a hierarchy, with each other node having only one parent node and one or more possible child nodes.

A technology is described for operating a multi-tiered data processing service. An example method may include receiving a data rule set used to process data generated by a network addressable device included in a multi-tiered data processing service having computing nodes that are connected using one or more networks, where the computing nodes may have computing capacities to execute a portion of the data rule set using a rules engine. A computing node included in the multi-tiered processing service may be selected to host a portion of the data rule set on the computing node and a portion of the data rule set may be deployed to the computing node, where the data rule set may be registered with the rules engine that executes on the computing node and data generated by the network addressable device may be processed using the rules engine and the data rule set.

Providing selective peer-to-peer monitoring using MBeans by providing a federation of peer-to-peer network servers based on the MBeans, and enabling each of the peer-to-peer networks servers to selectively monitor data associated with at least a subset of the peer-to-peer network servers using at least one of the MBeans.
