Dynamic control of authorization to access internet services
Programmable storage media including programmable software for managing authorization to access Internet services. A session object is created when a user logs onto a web site. The session object includes authorization-privilege information for N services. The user selects the service desired from the web site, at which point the server checks the session object. If the session object does not include authorization to access the selected service, the server consults a directory service. If the user is authorized according to the directory service, authorization-to-access information is incorporated into the session object. When authorization is conditional, a listener object is created within the session object. The listener object registers with a broadcast object and receives information germane to conditions of authorization. The listener object analyzes the information according to conditions of authorization, and terminates access to the selected service when conditions of authorization are not satisfied. |

Detecting polymorphic threats
A polymorphic threat manager monitors an incoming email stream, and identifies incoming email messages to which executable files are attached. The polymorphic threat manager characterizes incoming executable files according to at least one metric. For example, the polymorphic threat manager can decompose an executable file into fragments, hash some or all of these, and use the hashes as characterization metrics. The polymorphic threat manager subsequently de-obfuscates executable files, and creates corresponding characterization metrics for the de-obfuscated images. The characterizations of executable files before and after de-obfuscation are compared, and if they differ sufficiently, the polymorphic threat manager determines that the file in question is polymorphic. The characterization metrics of such an executable file after de-obfuscation can be used as a signature for that file. |

DRAM power management in a memory controller
A memory controller uses a power- and performance-aware scheduler which reorders memory commands based on power priorities. Selected memory ranks of the memory device are then powered down based on rank localities of the reordered commands. The highest power priority may be given to memory commands having the same rank as the last command sent to the memory device. Any memory commands having the same power priority can be further sorted based on one or more performance criteria such as an expected latency of the memory commands and an expected ratio of read and write memory commands. To optimize the power-down function, the power-down command is only sent when the selected memory rank is currently idle, the selected memory rank is not already powered down, none of the reordered memory commands correspond to the selected rank, and a currently pending memory command cannot be issued in the current clock cycle. |

Method and apparatus for supporting very large transactions
One embodiment of the present invention provides a system that executes a transaction on a multi-threaded processor. The system starts by executing the transaction in a “transaction-pending mode,” which involves placing load-marks or store-marks on cache lines loaded from or stored to during transaction-pending mode and also buffers store operations in a store queue. Upon encountering a store queue overflow, the system continues to execute the transaction in a “store-queue-overflow mode,” which involves placing load-marks or store-marks on cache lines loaded from or stored to during store-queue-overflow mode and discards store data which does not fit into the store queue during store operations. Upon completing the transaction in the store-queue-overflow mode, the system re-executes the transaction in a “repeating-transaction mode,” which involves executing the instructions in the transaction non-speculatively, which allows the store operations to commit to the memory hierarchy. |

Pattern discovery techniques for determining maximal irredundant and redundant motifs
Basis motifs are determined from an input sequence though an iterative technique that begins by creating small solid motifs and continues to create larger motifs that include “don't care” characters and that can include flexible portions. The small solid motifs, including don't care characters and flexible portions, are concatenated to create larger motifs. During each iteration, motifs are trimmed to remove redundant motifs and other motifs that do not meet certain criteria. The process is continued until no new motifs are determined. At this point, the basis set of motifs has been determined. The basis motifs are used to construct redundant motifs. The redundant motifs are formed by determining a number of sets for selected basis motifs. From these sets, unique intersection sets are determined. The redundant motifs are determined from the unique intersection sets and the basis motifs. This process continues, by selecting additional basis motifs. |

The NID or host receives the transferred TCP connection and the transferred clock value, and decides whether to update its own clock to equal the transferred clock value, the decision being guided by the requirement to never allow the timestamp clock to run backward. Acceleration of the timestamp clocks is prevented so that RTT measurements are accurate. Synchronization of the host and NID timestamp clocks improves performance and reduces erroneous connection drops. |

Method of determining a maximum transmission unit value of a network path using transport layer feedback
A network element implementing a method for determining an optimal maximum transmission unit (MTU) value on a path between two nodes in a network is described. A sending node interested in learning the optimal MTU path value allows fragmentation of datagrams sent on the path, selects an initial MTU, and sends one or more data packets to a receiving node. Upon receiving the data the receiver determines if fragmentation occurred. If no fragmentation occurred then the MTU path selected is the optimal MTU for the given path between the nodes. If fragmentation did occur then the sender is notified that the selected MTU was not the optimal MTU for the path. Either the receiver proposes a new MTU for the path, or the sender selects a new, smaller MTU. The process repeats until the receiver detects no fragmentation. |

Performing non-revertive failover with network devices
Techniques are described for performing non-revertive failover with network devices. A network device including a control unit and interface cards receives routing information protocol (RIP) updates each having a metric value. The control unit signals bidirectional forwarding detection (BFD) sessions based on the metric values of each of the RIP updates with, for example, a media gateway. The control unit also selectively installs a RIP route based on the metric values. The media gateway monitors the BFD sessions, and upon failure of an active BFD session, indicates the network device to perform non-revertive failover by sending a revised plurality of RIP updates. The network device performs non-revertive failover according to the revised plurality of RIP updates. Because of the flexibility of BFD, the network device need not revert back to a previous RIP route, therefore curtailing excessive failover. |

System, device, and method for managing alternate site switching in an optical communication system
A system, device, and method for managing alternate site switching in an optical communication system recovers from failures/degradations that are uncorrected by the core optical communication network. When an uncorrected failure/degradation is detected, communications for a protected end-system are switched from a primary end-system to a backup end-system. The backup end-system may be selected a priori, for example, during connection establishment, in order to reduce switching time once a decision has been made to switch communications from the primary end-system to the backup end-system. Provisions are made for completing the alternate site switching within a specified amount of time. Load balancing may be used to further reduce switching time from the primary end-system to the backup end-system. This alternate site switching augments the various protection mechanisms provided by the core optical communication network in order to provide end-to-end protection for the optical communication path. |

Optical information recording device, optical information recording method, and signal processing circuit
It is an object of certain inventive aspects to provide a recording condition closer to an optimum even for a medium unknown to a drive, and more particularly, to provide means for obtaining a preferable recording condition even for a high-speed recording in which conducting a test recording is difficult. In order to accomplish the object, a power and a phase of a recording pulse are simultaneously corrected at predetermined timing, depending on a recording speed or a recording position such as an inner or outer circumference. For instance, a phase shift ΔPhase generated due to a continuing recording from an inner circumference to an outer circumference at ×2 speed is corrected simultaneously with a correction of a power shift at the timing when a recording speed is changed from ×2 to ×4. For the other recording speed, in the same manner as above, a power and a phase shift are simultaneously corrected at every time when a recording speed is changed. |

Information recording method and apparatus, information reproducing method and apparatus, information recording medium, program storage medium and program
Congested rewriting in the same area is to be evaded to suppress the tendency towards occurrence of defective areas. When a stream 1 has been recorded, the last written address, representing the last written position, is stored. When recording a stream 2 next, recording is started directly following the position indicated by the last written address for the stream 1. The last written address, corresponding to the last address of the recording position, is stored. If the stream 2 is erased for recording a stream 3, recording is started not at a position directly following the last written address of the stream 1, but from a position directly following the last written address of the stream 2. When the stream 3 has reached the end of a recording area, the next following data is recorded as from a position directly following the stream 1. |
