20100150161 | METHODS AND SYSTEMS FOR AUTOMATIC TRANSPORT PATH SELECTION FOR MULTI-HOMED ENTITIES IN STREAM CONTROL TRANSMISSION PROTOCOL - The present disclosure provides methods and systems for automatic transport path selection for multi-home entities in Stream Control Transmission Protocol (SCTP). The present invention provides systems and methods for directing data transfer between applications and devices residing on different computers or devices using a dynamic path selection algorithm for multi-homed network entities (using SCTP). When an application or device requests to transfer data to another application or device, the dynamic path selection algorithm selects the most efficient path for data transfer. The decision to select the best network path is based upon the dynamic network conditions, such as, for example, congestion window (CWND), round trip time (RTT), and the like, and/or provisioning information. | 06-17-2010 |

20140071825 | LOAD BALANCING SYSTEMS AND METHODS OF MAC LEARNING IN MULTI-SLOT ARCHITECTURES - Line cards in a multi-slot network element utilize load balancing systems and methods for synchronizing learned Media Access Control (MAC) addresses therebetween. It is an objective of the load balancing systems and methods to enable high data rate scalability between line cards in a distributed system while preventing adverse effects on packet traffic. The load balancing systems and methods include inter alia MAC address updates between data path devices (e.g., network processors, application specific integrated circuits, etc.) using data frames and a hash-based time slot strategy ensuring MAC address updates are distributed over time as opposed to large scale, singular events. | 03-13-2014 |
20140247829 | SYSTEMS AND METHODS FOR SYNCHRONIZING FORWARDING DATABASES ACROSS MULTIPLE INTERCONNECTED LAYER-2 SWITCHES - A method and a multi-switch architecture include learning a media access control (MAC) address at a first switch in a multi-switch architecture; storing the MAC address in a forwarding database of the first switch; transmitting a data frame to one or more switches in the multi-switch architecture via inter-switch connectivity between the first switch and the one or more switches, wherein the data frame is created to enable the one or more switches to learn the MAC address therefrom; learning the MAC address from the data frame at the one or more switches; and storing the MAC address in a forwarding database for each of the one or more switches. This further includes transmitting the data frame via ports and queues in the inter-switch connectivity that are separate from ports and queues in a data path between the first switch and the one or more switches to avoid data path interference. | 09-04-2014 |

20140380474 | System and Method for Detecting Time-Bomb Malware - According to one embodiment, a system comprises one or more counters; comparison logic; and one or more hardware processors communicatively coupled to the one or more counters and the comparison logic. The one or more hardware processors are configured to instantiate one or more virtual machines that are adapted to analyze received content, where the one or more virtual machines are configured to monitor a delay caused by one or more events conducted during processing of the content and identify the content as including malware if the delay exceed a first time period. | 12-25-2014 |

20150096022 | DYNAMICALLY ADAPTIVE FRAMEWORK AND METHOD FOR CLASSIFYING MALWARE USING INTELLIGENT STATIC, EMULATION, AND DYNAMIC ANALYSES - Techniques for malware detection are described herein. According to one aspect, control logic determines an analysis plan for analyzing whether a specimen should be classified as malware, where the analysis plan identifies at least first and second analyses to be performed. Each of the first and second analyses identified in the analysis plan including one or both of a static analysis and a dynamic analysis. The first analysis is performed based on the analysis plan to identify suspicious indicators characteristics related to processing of the specimen. The second analysis is performed based on the analysis plan to identify unexpected behaviors having processing or communications anomalies. A classifier determines whether the specimen should be classified as malicious based on the static and dynamic analyses. The analysis plan, the indicators, the characteristics, and the anomalies are stored in a persistent memory. | 04-02-2015 |

20090175270 | TELEPHONE RECORDING AND STORING ARBITRARY KEYSTROKES SEQUENCE WITH REPLAY WITH A SINGLE STROKE - A telephone is described that allows any arbitrary combination of key strokes, including numerical keys, extension keys, as well as function keys such as TRANSFER, CONFERENCE, etc., to be programmed such that the entire sequence of key strokes can be recalled with the touch of a single button. The phone can be programmed directly by operation of the telephone user interface on the phone (i.e., the keys, phone display, and speaker prompting the user) and a program button dedicated to the feature of programming a separate programmable button to map to the specified key sequence. The feature can be implemented in advanced telephones capable of voice over Internet Protocol networks, and supporting the Session Initiation Protocol. In these more advanced phones, the programming can be done by a system administrator or by the user of the phone via a computer with internet access. | 07-09-2009 |
20090245239 | PERFORMING OPERATIONS ON IP TELEPHONY DEVICE FROM A REMOTE CLIENT - A method and system for remotely accessing an intelligent IP telephony device is provided. Information about at least one IP telephony device associated with a user is stored in a database. The database is accessible to a user through a secured environment. From a remote location, the user may logon to the database and select one or more actions to be performed on any of the IP telephony devices to which they have access. | 10-01-2009 |

20090037564 | System and Method for Multiple Address of Record Deregistration Using a Single SIP Request - One embodiment of the present invention is a method for deregistering multiple addresses of record. The method comprises receiving a session initiation protocol request to deregister addresses of record, the session initiation protocol request comprising a plurality of addresses of record to be deregistered and a contact address for a session initiation protocol endpoint. The method further comprises disassociating the contact address for the session initiation protocol endpoint from each of the plurality of addresses of record. | 02-05-2009 |
20090037590 | System and Method for Multiple Address of Record Registration Using a Single Implicit SIP Request - One embodiment of the present invention is a method for registering multiple addresses of record. The method comprises receiving a session initiation protocol register request, the session initiation protocol register request comprising a unique identifier of a session initiation protocol endpoint and a contact address for the session initiation protocol endpoint. The method proceeds by retrieving one or more addresses of record associated with the unique identifier of the session initiation protocol endpoint. The method further comprises associating each of the one or more addresses of record with the contact address for the session initiation protocol endpoint. | 02-05-2009 |
20090038000 | System and Method for Multiple Address of Record Registration Using a Single Explicit SIP Request - One embodiment of the present invention is a method for registering multiple addresses of record.
