Abstract: The present invention, in particular embodiments, is directed to methods, apparatuses and systems that provide an efficient compression technique for data streams transmitted to storage devices or over networks to remote hosts. Local storage as well as network transmission of streams is made more efficient by awareness and utilization of repeated sequences of data blocks. Such data blocks can be placed in a dictionary on persistent storage and shared across all streams. The dictionary is hierarchically indexed (two or more levels of indexing) to combine high efficiency search with efficient access to the stored data blocks. Additionally, data blocks, in particular implementations, are stored sequentially in order to improve overall performance.

Abstract: Methods, apparatuses, and systems directed to efficient compression processing in system architectures including a control plane and a data plane.

The power distribution manager provides one or more operating voltages and, in response to the processing demand, switches between a first set of voltages and a second set of voltages without halting the processing system.

Abstract: This document describes tools that enable data network equipment to use its permitted data rate or physical maximum rate even if one of its links fail or it transmits more data on some links than others. To do so, the tools may track how much of a permitted data rate is used by a group of physical links. If the group is using more than the permitted data rate, the tools may limit the group to that rate. If some of the physical links in the group fail, the tools enable the group to use either its permitted data rate or the physical maximum rate of the group. In addition, the tools allow unique permitted data rates in two directions by a group of physical links. The tools may be used at ingress or egress modules within equipment depending upon the application and implementation.

Further, the system and the method may use an event database to determine current interests of the user. Still further, the system and the method for generating a recommendation on a mobile device may use a transactional history of the user and/or behavior of other users to generate the recommendation. The system and the method may recommend, for example, digital media, news and event information, editorial content and/or physical or digital merchandise. As a result, the system and the method may generate a recommendation that corresponds to the current interests of the user.

Abstract: Systems and methods of establishing IP telephony sessions between enterprises are disclosed. A first enterprise requests an association with a second enterprise. Both enterprises and the second enterprise belong to the same federation. The association request is accepted, to establish an association between the first and second enterprises. In response to the acceptance, a direct routed path is established between the first enterprise and the second enterprise. One of the associated enterprises requests activation of an IP telephony service. If the request to activate references the association, an IP telephony session is established using the direct routed path.

Abstract: A system and a method create metadata for media files. The metadata may be information relating to, based on and/or associated with the media files. The metadata of the media files may be searched by one or more terminals. An event database connectable to a terminal may use a location, a date and/or a time of creation of the media files to associate specific events with the media files. Further, the specific events may be used by the database to create keywords associated with the media files. As a result, the system and the method may organize and/or may provide searching for media files. A web page may be generated for an event that accumulates the media files related to the event.

Abstract: A data and control plane architecture for network devices. An example system architecture includes a network processing unit implementing one or more data plane operations, and a network device operably coupled to the network processing unit that implements a control plane. In a particular implementation, the network processing unit is configured to process network traffic according to a data plane configuration, and sample selected packets to the network device. The network device processes the sampled packets and adjusts the data plane configuration responsive to the sampled packets. In particular implementations, the control plane and data plane implement a server-side triggered policy caching mechanism that allows for previous classification policy decisions made for previous data flows to be applied to subsequent new flows.

Write records are attached to the hierarchical index as leaf nodes with a possibility of being split into two or more leaf nodes if a write record traverses multiple data ranges. Additionally, the hierarchical index can conditionally grow based on a number of leaf nodes attached to a given stem node in the hierarchical index.

Abstract: Methods, apparatuses and systems directed to improving the efficiency of bandwidth allocation schemes by adapting to slow-start mechanisms associated with network communications protocols, such as the TCP/IP protocol suite. In one implementation, the present invention scales down the initial target rate assigned to a data flow to a fraction of an initial estimate of the effective rate capacity of the communications path between two hosts. As packets are received, the target rate is gradually increased, eventually up to the detected rate capacity of the communications path. Implementations of the present invention improve the efficiency of bandwidth allocation by reducing the over-allocation of bandwidth to data flows during the slow-start phase, leaving more bandwidth available to other data flows.

Abstract: This invention includes methods and packet switches that translate a packet between a switching format and a transport format. One packet switch receives a packet intended for a destination port of a packet switch from a switching fabric of the packet switch and determines, based on the destination port, a treatment to be applied to the packet. The packet switch then applies the treatment to the packet prior to forwarding the packet to the destination port. The treatment may include adding a transport identifier to the packet.

A microwave illuminator of the microwave control unit is applied to send a microwave signal. After receiving the microwave signal, the control card reflects a reflection signal to the microwave control unit, wakes up from a first sleep mode to enter a first awake mode, and sends a first control signal to the passive control unit. After the microwave control unit receives the reflection signal, the passive control unit wake up from a second sleep mode to enter a second awake mode, and the passive control unit transmits a second control signal in accordance with the first control signal to the working system, so as to control the working system to execute the predetermined assignment.
