Abstract: Techniques are provided to move the services performed on one device to another device in a cloud computing system for a variety of reasons including failure, maintenance or upgrade of the device. A notification is received that services performed by an impacted device in a domain of a plurality of hierarchical domains need to be moved. A determination is made as to whether there are replacement resources available in the domain to perform the services, and if so, the replacement resources are automatically rendered to perform the services. The process continues to higher level domains that have a view into the capabilities of subordinate domains in order to determine where to move the services within the cloud computing system.

Abstract: A system and method are described that enable policy-implementing modules in a mobile wireless network to identify the location of a user and render policy-based (e.g., quality of service, accounting, throttling, etc.) decisions based upon a variety of additional information such as: home network availability in a market, user class, time of day, network congestion, application type, etc. The system renders policy decisions, based upon geo-spatial location information, by receiving a mobile wireless data message including a geospatial identifier. Thereafter, a policy engine renders a data service policy decision by applying a policy to the geospatial identifier. The potential classifications identified by the data service policy decision include an in-market roaming mode wherein a data usage is treated as non-roaming, even though associated with a roaming data session, based upon an in-market location specified by the geospatial location information.

Abstract: A way for managing use of a mobile wireless device in a tethering configuration is described. The disclosed mobile wireless system is configured to receive a message packet issued from a device tethered to the mobile wireless device. The system determines whether the mobile wireless device is permitted to pass messages on behalf of tethered devices by referencing a profile with which the mobile device is associated. The mobile wireless system discards the received message packet in response to determining from the profile that the mobile wireless device is not permitted to pass messages on behalf of tethered devices. Moreover, a number of ways for monetizing the supported tethering mode are described such that a service provider is adequately compensated for the increased demand on the mobile wireless network resources arising from support for the tethering mode of operation for a mobile wireless device.

Abstract: Managing data resource utilization in a wireless network environment comprising a first data network and a second data network is described herein. The described management infrastructure and method incorporates monitoring data usage of a wireless network subscriber over the first data network, determining that the data usage over the first data network meets a specified threshold, and, in response to the determination that usage has reached the specified threshold, administratively disconnecting the wireless network subscriber from the first data network so as to cause a data session of the wireless network subscriber to be reassigned to the second data network.

Abstract: This disclosure relates to techniques for performing display mode based video encoding to reduce power consumption in a source device of a Wireless Display (WD) system. More specifically, the techniques enable the source device to select an encoding process based on whether the video data to be encoded is in a static display mode or a dynamic display mode. For example, when the video data is in the static display mode, the source device selects a static encoding process that reduces an amount of video data processing and compression, which in turn reduces power consumption at the source device. When the video data is in the dynamic mode, the source device may select a conventional dynamic encoding process. The source device encodes the video data according to the selected encoding process, and transmits the encoded video data to one or more sink devices in the WD system for display.

Abstract: Techniques are provided herein for detecting that virtual data center services provided to one of at least two customers are being subjected to an attack, wherein the virtual data center services are provided to the least two customers using a same first set of physical servers via a first network element such as a physical access switch, and responsive to detecting that virtual data center services provided to the one of the at least two customers are being subjected to an attack (e.g., a virus or denial of service attack), the technique causes the virtual data center services provided to the one of the at least two customers to be migrated to, e.g., instantiated on, a second set of physical servers that is not accessible via the first network element.

Abstract: Graph-based virtual data center requests are described. In some implementations, a method includes displaying a graph having graphical elements representing network resources. A user can select one of the graphical elements and provide input specifying requirements for a network resource corresponding to the selected graphical element. A virtual data center request can be generated based on the graph and the specified requirements. The virtual data center request can be transmitted to a data center device for processing. In some implementations, the virtual data center request can be an extensible markup language (XML) representation of the graph that includes the specified service requirements. In some implementations, a data center server can receive a graph-based virtual data center request and allocate data center resources based on the virtual data center request.

Abstract: At a data switching device in a data center, it is detected whether a host has connected to a cloud computing network of which the data switching device and the data center are components. The detection is performed without directly communicating with the host. The data switching device determines properties of the host and generates a message comprising data representative of the properties of the host. The message is sent from the data switching device to a node in the cloud computing network that is configured to manage components of the cloud computing network associated with the host.

Abstract: Network worms or viruses are a growing threat to the security of public and private networks and the individual computers that make up those networks. A content sifting method if provided that automatically generates a precise signature for a worm or virus that can then be used to significantly reduce the propagation of the worm elsewhere in the network or eradicate the worm altogether. The content sifting method is complemented by a value sampling method that increases the throughput of network traffic that can be monitored. Together, the methods track the number of times invariant strings appear in packets and the network address dispersion of those packets including variant strings. When an invariant string reaches a particular threshold of appearances and address dispersion, the string is reported as a signature for suspected worm.

Multiple such messages may be received at an aggregation node that then summarizes the attributes according to respective functions, and sends or publishes a summarized version of the attributes to a still next higher node in the network hierarchy.
