摘要: A system and method are provided for encoding and decoding multiplexed video signals to de-jitter the content. A first de-jitter operation is performed on incoming signals and a second de-jitter operation is performed on PCR modified outbound packetized signals after sequencing of the packetized signals has been determined. In one case the second de-jitter operation can be performed using a PLL that is based, at least in part, on the output hardware limitations.

摘要: Systems, methods, and computer-readable media for annotating process and user information for network flows. In some embodiments, a capturing agent, executing on a first device in a network, can monitor a network flow associated with the first device. The first device can be, for example, a virtual machine, a hypervisor, a server, or a network device. Next, the capturing agent can generate a control flow based on the network flow. The control flow may include metadata that describes the network flow. The capturing agent can then determine which process executing on the first device is associated with the network flow and label the control flow with this information. Finally, the capturing agent can transmit the labeled control flow to a second device, such as a collector, in the network.

摘要: Techniques are described for analyzing data regarding activity in an IT environment to determine information regarding the entities associated with the activity and using the information to detect anomalous activity that may be indicative of malicious activity. In an embodiment, a plurality of events reflecting activity by a plurality of entities in an IT environment are processed to resolve the identities of the entities, discover how the entities fit within a topology of the IT environment, and determine what the entities are. This information is then used to generate an entity relationship graph that includes nodes representing the entities in the IT environment and edges connecting the nodes representing interaction relationships between the entities. In some embodiments, baselines are established by monitoring the activity between entities. This baseline information can be represented in the entity relationship graph in the form of directionality applied to the edges. The entity relationship graph can then be monitored to detect anomalous activity.

摘要: Methods, apparatus, systems and articles of manufacture are disclosed to facilitate proximity detection and location tracking. An example method includes receiving messages collected by a badge in an environment, the messages including signal strength and a timestamp. The example method also includes assigning a location in the environment to the badge based on a first subset of the messages. The example method also includes identifying an asset in a second subset of the messages. The example method also includes updating a current location associated with the asset based on a relative proximity of the asset to the badge, wherein the current location corresponds to a first time and the updated location corresponds to a second time, and wherein a change in location between the current location and the updated location indicates movement of the asset in the environment.

摘要: A process for authenticating a communication device may include receiving a request from a communication device to synchronize time with a server, and providing an authorization network time to the communication device. An authentication request including an access credential having a timestamp generated by the communication device may be received by the server. A determination can be made as to whether the communication device had successfully executed a predetermined shutdown sequence by determining whether the access credential has reliable timestamp information. The communication device can be authenticated when the timestamp has a non-reset value indicating that the communication device had successfully executed the predetermined shutdown sequence, and that the access credential has not expired. Step-up authentication for the communication device can be requested when the access credential has unreliable timestamp information indicating that the communication device did not successfully execute the predetermined shutdown sequence.

摘要: Networked devices are arranged to play content such as audio and video content in synchronization. A synching device receives a packet from an initiating device over a network. The packet may include an identifier of content to play, such as a URI, and an indication of when to play the content. A local clock time to play the content is determined based on a time of a local clock of the first device and the indication of when to play the content. The synching device obtains from a server the content based on the received identifier, and plays the content in synchronization with the initiating device based on a time on the local clock and the local clock time to play the content. In some embodiments, the synching device also adjusts a clock speed of the local clock reference to control rate of playback of the content.

摘要: A system, computer readable medium, and method are provided for a resource management in a cloud architecture. The method includes the steps of collecting a first time stamped data (TSD), and a second TSD, and generating a prediction model based on the first TSD and the second TSD. The method further includes collecting a third TSD, and predicting a fourth TSD based on the prediction model and the third TSD. With more data are obtained via the prediction, the resource management is more efficient and accurate.

摘要: A method for monitoring a network includes generating a first receiving sequence number representing a first location within a first ordered sequence of a number of data packets as received by a receiving device, and extracting a first transmission sequence number representing a second location within a second ordered sequence of the number of data packets as transmitted by a transmitting device. The method further includes generating a second receiving sequence number representing a third location within the first ordered sequence of the number of data packets, extracting a second transmission sequence number representing a fourth location within the second ordered sequence of the number of data packets. The method further includes generating a measurement of network transmission based at least on the first receiving sequence number, the first transmission sequence number, the second receiving sequence number, and the second transmission sequence number.
