A Provider Network Controller (PNC) addresses the challenges in building services across Next Generation Network (NGN) architectures and creates an abstraction layer as a bridge, or glue, between the network transport and applications running over it. The PNC is a multi-layer, multi-vendor dynamic control plane that implements service activation and Layer 0-2 management tools for multiple transport technologies including Carrier Ethernet, Provider Backbone Transport (PBT), Multi-protocol Label Switching (MPLS), Transport MPLS (T-MPLS), optical and integrated networking platforms. Decoupling transport controls and services from the network equipment simplifies service creation and provides options for carriers to choose best-in-class equipment that leverages the PNC to enable rapid creation and management of transports and services. The PNC provides Service-Oriented Architecture (SOA) interfaces to abstract transport objects expressly designed to support both wholesale and retail services, and supports service offerings with varied bandwidth and Quality of Service (QoS) requirements, thus achieving enterprise Ethernet economics.

A network management system is provided that allows a user to configure multiple devices according to a consistent set of policies. The system includes a device learning module that can read configuration data from a network device and automatically match that configuration data to existing policies and components of policies within the system. The device learning module also identifies unknown configuration data, which does not match any existing policy. The system further includes a grammar builder that can parse the unknown configuration data and construct a component or policy from the unknown data, by matching the unknown data to a grammar of configuration commands for the network device. The system also provided auditing capabilities, where policies are compared to running network configurations, and differences are identified.

A data storage caching architecture supports using native local memory such as host-based RAM, and if available, Solid State Disk (SSD) memory for storing pre-cache delta-compression based delta, reference, and independent data by exploiting content locality, temporal locality, and spatial locality of data accesses to primary (e.g. disk-based) storage. The architecture makes excellent use of the physical properties of the different types of memory available (fast r/w RAM, low cost fast read SSD, etc) by applying algorithms to determine what types of data to store in each type of memory. Algorithms include similarity detection, delta compression, least popularly used cache management, conservative insertion and promotion cache replacement, and the like.

Embodiments of the invention provide a framework for traffic classification that bridges the gap between the packet content inspection and the flow-based behavioral analysis techniques. In particular, IP packets and/or IP flows are used as an input, network nodes are associated to specific network applications by leveraging information gathered from the web, and packet-level and/or flow-level signatures are extracted in an off-line fashion using clustering and signature extraction algorithms. The signatures learned are systematically exported to a traffic classifier that uses the newly available signatures to classify applications on-the-fly.

For a host that executes one or more guest virtual machines (GVMs), some embodiments provide a novel encryption method for encrypting the data messages sent by the GVMs. The method initially receives a data message to send for a GVM executing on the host. The method then determines whether it should encrypt the data message based on a set of one or more encryption rules. When the process determines that it should encrypt the received data message, it encrypts the data message and forwards the encrypted data message to its destination; otherwise, the method just forwards the received data message unencrypted to its destination. In some embodiments, the host encrypts differently the data messages for different GVMs that execute on the host. When two different GVMs are part of two different logical overlay networks that are implemented on common network fabric, the method in some embodiments encrypts the data messages exchanged between the GVMs of one logical network differently than the data messages exchanged between the GVMs of another logical network. In some embodiments, the method can also encrypt different types of data messages from the same GVM differently. Also, in some embodiments, the method can dynamically enforce encryption rules in response to dynamically detected events, such as malware infections.

The invention provides a method for extracting an image region of interest by combining bottom-up and top-down ways. In the method, an interactive way is adopted, a user converts top-down information of observation tasks carried by the user into different weight values which are used for inputting the image bottom-layer features, an Itti-Koch model and a Stentiford model are combined, and the advantages of the two models are absorbed, thus the method for extracting region of interest combined with a user task and image visual stimulation is realized. Inquiry intention of the user and understanding on the image are converted into weights of a saliency map, namely the bottom-layer features are added corresponding weights to influence the solution of the saliency map, thus a gap between the inquiry intention of the user and the bottom-layer features of an image is reduced and the extracted region of interest is more consistent with the requirement of the user. The processing results of multiple images show that better result can be obtained by adopting the method to extract the region of interest for the user.

The spatial locations of each object deemed important is output to the user by varying output to the haptic transducers accordingly. The system is configured to identify and report objects as generic objects, identified objects, and potential obstacle objects. The system can also optionally provide audio information pertaining to these objects as well.

An RFID bridge antenna is positioned between a tag antenna associated with a tag and a reader antenna associated with a reader. The bridge includes at least two RF antenna elements spaced apart from one another and coupled together by an electrical conductor. The first RF antenna element is located proximate to the tag antenna and the second RF antenna element is located proximate to the reader antenna. An electromagnetic carrier signal transmitted by the reader antenna is received by one of the RF antenna element and retransmitted to the tag antenna by the other RF antenna element, increasing the distance over which the tag can communicate with the reader. Where the tag is attached to a packaged object, the RFID bridge antenna may be included in the package to allow wireless data communication between the tag and a reader. The reader may also be located external to the package. For example, one of the RF antenna elements may be attached to a label on the package, allowing data stored in the tag to be extracted by the external reader. The object may be a module, also known as a customer replaceable unit (CRU), and the tag may be configured as a customer replaceable unit monitor (CRUM).
