Abstract: Systems and methods are disclosed for network event grouping. For example, methods may include generating a graph including vertices and edges, wherein at least one of the vertices is associated with an event type from a set of event types and wherein at least one of the edges is associated with a weight; removing, based on an associated weight and a first threshold, one or more edges from the graph; determining, after removing the one or more edges from the graph, whether the graph is chordal; responsive to determining that the graph is chordal, identifying a connected subgraph within the graph; determining a group of event types to include event types that are associated with vertices in the identified connected subgraph; and transmitting, storing, or displaying data specifying the group of event types.

Abstract: Disclosed herein is a system and method to synchronize files from a hosted file system where the client endpoint devices have direct access to the files stored on a hosted file store. When the client desires to synchronize with the files stored on the hosted file store the process identifies a sync role that can process the request. The particular sync role does not need to maintain state with the client device or the file store. The state necessary for the processing of the synchronization process is maintained separate from the sync role such that any sync role in the system can pick up the requests and process the requests. Once the role has been selected the synchronization process proceeds as normal. As state is not maintained by the sync role multiple roles can process the request or two roles can handle different portions of the process.

Abstract: A computer implemented system and method for pro-active application monitoring and alerting using affinity band. To enable pro-active monitoring, the present invention may derive affinity band. The invention accesses performance data generated from monitoring an application associated with one or more transaction and configuring iteration period to derive affinity band. The method provides configuring an interval within iteration period whereby all performance metric values may be aggregated and deriving affinity band for each of the performance metrics. The affinity band may then be used as benchmark or threshold to monitor current values for each of the performance metrics. Alerts may be raised through pro-active monitoring mechanism when the current values of the performance metric go beyond the threshold set, displaying a tendency to rise or go beyond normal values with extent of deviation.

The method also includes receiving a confirmation from a first registered provider of the one or more registered providers that the first registered provider will provide the requested item. The method further includes transmitting payment information for the item request to a payment processor. The method also includes transmitting a notification to the first registered provider to provide the requested item.

Abstract: Systems and methods for automated commissioning of virtualized distributed control systems are disclosed. An example method includes accessing a data structure including a list of configuration names for network cards associated with first and second host servers of a virtual process control environment. The first and second host servers implement virtual machines corresponding to workstations for a process control system. The example method also includes when configuring the first host server, assigning a first name to a first one of the network cards associated with the first host server. The example method further includes when configuring the second host server, assigning the first name to a second one of the network cards associated with the second host server based on a user selection of the first name from the list of configuration names. The second host server is configured after the first host server.

Abstract: A computer system receives digital content for communication to a user. Digital fingerprints are calculated from the digital content. The fingerprints are compared to identify redundant digital content. Digital identifications associated with the digital fingerprints are communicated to a user device to determine whether the digital content exists in local storage.

Abstract: A method comprises receiving content from a source, and generating multiple content streams each comprising the received content. Each content stream includes segments comprising respective portions of the received content. Different segmenting is utilized in generating respective ones of the content streams such that the segments in each of the content streams are offset in time relative to corresponding segments in the other ones of the streams. For example, generating the multiple content streams may comprise segmenting n content streams such that each content stream comprises segments of length Ts with corresponding segments in adjacent ones of the content streams being offset from one another by an offset Tg. Such an arrangement ensures that latency shift upon switching between one of the content streams and another content stream in a different set of multiple content streams at a client device can be limited to a value approximated by Tg.

Abstract: Accessing data stored on a remote server includes determining a first address of a first server where a block of data identified by a key has been moved from a second server to the first server, the second server having a second address. A first entry of a switch flow table of a datacenter network is updated to indicate that received packets with a destination address including the second address are to be overwritten with the first address. The data center network includes a plurality of physical network switches. A second entry in the switch flow table may be configured to forward packets with the first address to a first port associated with the first server and a first set of the switches. If the second entry is not already present in the table, the second entry may be inserted into the switch flow table.

Abstract: Techniques are disclosed for notifying network control software of new and moved source MAC addresses. In one embodiment, a switch detects packets sent by a new or migrated virtual machine, and sends a copy of a detected packet to the network control software as a notification. The switch further learns the source MAC address, thereby permitting the entry to be used for normal forwarding prior to validation of the entry and the VM associated therewith by the network control software. Until the network control software has validated the VM, the switch may periodically retry the notification to the network control software. “No_Redirect” and “Not_Validated” flags may be used to indicate whether a notification has already been attempted and thus no retry is necessary, and that the VM associated with the VM has not yet been validated, respectively.

Abstract: Various embodiments manage the migration of servers. In one embodiment, a set of server-level dependency information is obtained for servers to be migrated from a source computing environment to a target computing environment. A set of network configuration data is obtained for a plurality of network devices associated with the servers. The set of server-level dependency information is updated to include one or more additional dependencies of at least one of the servers based on the set of network configuration data. Updating the set of server-level dependency information generates an updated set of dependency information. The servers are assigned to multiple migration groups based on the updated set of dependency information. The migration groups optimize cross-group dependencies among the migration groups.

Abstract: A computer-implemented method, operable on a device in a content delivery network (CDN), wherein the CDN delivers content on behalf of at least one content provider, the device implementing a content delivery (CD) service, the method includes, by the service on the device: receiving a request for a particular resource from a client; determining whether the client includes an optimization support mechanism; when the client includes an optimization support mechanism, providing the client with a first version of the particular resource, optimized, at least in part, for the capabilities of the client in combination with the optimization support mechanism; otherwise providing the client with either (i) an un-optimized version of the particular resource, or (ii) a version of the particular resource optimized, at least in part, for the capabilities of the client without the capabilities of the optimization support mechanism.

Abstract: Stream-based data deduplication is provided in a multi-tenant shared infrastructure but without requiring “paired” endpoints having synchronized data dictionaries. Data objects processed by the dedupe functionality are treated as objects that can be fetched as needed. As such, a decoding peer does not need to maintain a symmetric library for the origin. Rather, if the peer does not have the chunks in cache that it needs, it follows a conventional content delivery network procedure to retrieve them. In this way, if dictionaries between pairs of sending and receiving peers are out-of-sync, relevant sections are then re-synchronized on-demand. The approach does not require that libraries maintained at a particular pair of sender and receiving peers are the same. Rather, the technique enables a peer, in effect, to “backfill” its dictionary on-the-fly. On-the-wire compression techniques are provided to reduce the amount of data transmitted between the peers.

Abstract: A podcast system and method are provided to select and deliver media ads over a network to a user device and to insert the media ads in media content subscribed to and delivered over the network to the user device.

Abstract: A messaging service is described that facilitates the efficient receipt of messages by a client from across a large number of messaging entities hosted by different messaging hosts within a distributed messaging system. A gateway in the distributed messaging system forwards a request for an available message or set of related messages from the client to each of the messaging hosts. Each messaging host provides a response to a request if a messaging entity hosted thereby includes at least one available message or set of related messages. The messaging host manages the order in which responses from different messaging entities are provided to ensure fairness. The gateway forwards a selected one of the responses to the consumer, while caching the other responses to service future requests from the consumer.

Abstract: Systems and methods are disclosed for speedily upgrading (e.g., via service packs) components of a storage management system, such as media agents and data agents, which may number in the thousands. The disclosed methods and systems provide a lightweight and flexible approach. Executable files such as service packs are deployed to a network-shared file system and are served on demand to each targeted host computing device to launch a data agent and/or media agent component. New service packs (e.g., upgrades) are installed on another shared drive and the connection thereto is refreshed by each targeted storage management component to begin executing the new version on demand. The resultant overall upgrade process across the storage management system may be substantially shortened, and the network burden greatly reduced.

Abstract: In one embodiment, an application server to achieve improved quality of service (QoS) for content delivery in a communication network is disclosed. The application server receives a request from a client device to deliver content to the client device. The application server determines a relative priority of each of a plurality of content delivery servers in the communication network based on at least one of one or more parameters and a configuration file. The application server identifies at least one content delivery server from the plurality of content delivery servers based on relative priority. The application server identifies a shortest path for the content delivery between the identified at least one content delivery server and the client device based on one or more pre-defined rules. The application server further transmits the content from the identified at least one content delivery server to the client device via the identified shortest path.

Abstract: In accordance with one or more embodiments, aspects of the disclosure may provide efficient, effective, and convenient ways of managing network devices. In particular, a client router may connect to an upstream virtual gateway. The virtual gateway may manage a large number of client devices. Each client router may be represented virtually within the gateway as a virtual router. The virtual gateways may be distributed regionally, in order to manage large numbers of client routers and/or to reduce transmission delays. The virtual gateways may be managed by a gateway controller. The gateway controller may be centralized, and perform various configuration functions, such as configurations for hardware, logical networking, or content access policies. In some instances, messages sent between the gateway controller using a first protocol and the client router using a second protocol may be translated by a protocol agent.

Abstract: In an approach to location based augmented reality broadcasting, one or more computer processors determine a location of the one or more computing devices. The one or more computer processors determine whether two or more of the one or more computing devices are in the same location. In response to determining whether two or more of the one or more computing devices are in the same location, the one or more computer processors upload a first synchronized augmented reality data stream to the two or more computing devices in the same location.

Abstract: Systems and methods for augmenting, inferring, extrapolating, deducing, reasoning, and storing logical networks of information represented in digest form are disclosed. The disclosed systems and methods enable the combined inclusion of both sensitive information and non-sensitive information into a compressed, universal, indiscernible format. Relationships can be derived or inferred between unintelligible digests of information by associating them with a common underlying entity. A universal digest format described herein may become comprehensible by further utilizing additional a priori or a posteriori knowledge of the information such that recognized digests can be utilized fully while unknown and potentially sensitive digests remain undecipherable.
