Methods, apparatuses and systems allowing for dynamic bandwidth management schemes responsive to the state of a plurality of access links in redundant network topologies. In one embodiment, the present invention provides a bandwidth management device that periodically queries routing systems associated with access links, conceptually grouped into a virtual access link, to monitor that load of the access links and, depending on the detected load, adjust the configuration of the bandwidth management device to avoid overloading one or more of the access links. Embodiments of the present invention increases network efficiency and help network traffic to flow more smoothly with higher throughput. In one embodiment, the dynamic link control functionality is invoked when any given access link reaches a threshold capacity level. Assuming that network traffic will scale in the same ratio as presently observed, the present invention calculates the maximum traffic that can be let through so that no network interface or access link is overloaded.

The user is able to modify the playback speed of the multimedia content, allowing the playback to be either speeded up or slowed down.

Intrusion Prevention Systems (“IPSs”) are used to detect and / or prevent intrusion events from infiltrating a computer network. However, in large computer networks the IPSs cannot conduct their analysis on network data traffic quickly enough in the network core to meet the demand placed on them by the computer networks, thereby causing delays in the transmission of network data traffic from a source to a destination. To prevent this delay, the IPSs can be configured to intelligently communicate with a high-capacity network switch. The IPSs conduct the initial inspection of the network data traffic flows to determine if an intrusion event is present. However, after the initial inspection, the IPS can inform the switch of what actions to take for future traffic flows including determining which future traffic flows are inspected by the IPSs and which future traffic flows are allowed to be blocked or transmitted to their destination by the switch.

A workload scheduler supporting an efficient distribution and balancing of the workload is proposed. The scheduler maintains (383-386) a profile for each job; the profile (build using statistics of previous executions of the job) defines an estimated usage of different resources of the system by the job. The scheduler tends to select (318-342) the jobs with complementary resource requirements (according to a combination of their attributes); this process can be carried out using either a heuristic approach (318-334) or an optimization approach (335-342). As a result, the jobs that will be submitted are very likely to consume different resources of the system; in this way, any contention for the different resources is strongly reduced.

The previously uploaded data is subsequently downloaded from the remote system (1) to the mobile terminal (8) in the event that that data is required by the mobile terminal (8) or a determination is made that the risk of exceeding the data storage capacity of the mobile terminal (8) no longer exists.

Distributed CMTS device for a HFC CATV network serving multiple neighborhoods by multiple individual cables, in which the QAM modulators that provide data for the individual cables are divided between QAM modulators located at the cable plant, and remote QAM modulators ideally located at the fiber nodes. A basic set of CATV QAM data waveforms may be transmitted to the nodes using a first fiber, and a second set of IP / on-demand data may be transmitted to the nodes using an alternate fiber or alternate fiber frequency, and optionally other protocols such as Ethernet protocols. The nodes will extract the data specific to each neighborhood and inject this data into unused QAM channels, thus achieving improved data transmission rates through finer granularity. A computerized “virtual shelf” control system for this system is also disclosed. The system has high backward compatibility, and can be configured to mimic a conventional cable plant CMTS.

A method of limiting current in a DC motor acts on a full bridge circuit (137) through which the stator winding arrangement (102) of that motor is supplied with current. Upon response of the current limiter, energy supply to the stator winding arrangement (102) from the DC power network is interrupted. The stator winding arrangement is then operated substantially in short circuit via semiconductor switches of the full bridge circuit, and the decaying current flowing in that context serves substantially to continue driving the motor. When that current has reached a lower value, energy supply from the DC power network to the motor is once again activated. The effective value of the current flowing to the motor is preferably reduced when the current limiter responds. The time period during which that current flows, in the form of current blocks, is then increased in compensatory fashion.

A wind energy installation can include a generator which is driven by a rotor and generates electrical power in a multiphase manner for feeding into a network, a converter which is connected to the generator and to the network, and a control system which interacts with the converter and includes a negative sequence system regulation mechanism.

Accordingly, an available current can be provided according to the operating situation for active power or idle power in the negative sequence system regulation mechanism. The negative sequence system regulation mechanism can thus help stabilize the network in the event of asymmetrical network conditions. Also, this relates to a correspondingly equipped wind park and an operating method.

A refrigerant system includes a controller that enables the system to dehumidify the air in a room without relying on a humidistat and without having to operate the system's compressor and electric heater at the same time. To dehumidify the air, the system's compressor, supply air fan, and outside air damper are controlled in a manner similar to other systems operating in a cooling mode when the room temperature is above a certain setpoint temperature. When the room temperature falls below the setpoint, however, the operation changes significantly. The controller closes the outside air damper, decreases the speed of the fan, and continues operating in this manner until the room temperature decreases to a subcooling temperature limit. The subcooling temperature limit is less than a predetermined limit that is used during the system's normal cooling mode.

A network node in the communication network is a target network node, connected by a first communication path with at least one first and one second network node, connected to each other by means of a further communication path. A routing table is held in each network node. The direct communication path from the first network node to the target network node is entered in the routing table of the first network node as the primary routing path and the path leading from the first network node to the second network node and then to the target network node is entered as the reserve routing path. An analogous entry is made in the routing table of the second network node. The relevant reserve routing path is only used on disruption of the primary routing path. A disruption in the primary communication path, provided between the first network node and the target network node is reported by the first network node, by means of a message sent to the second network node. This controls the second network node such that, on a drop-out of the primary connection path thereof to the target network node, a transmission of data packets to the target network node by means of the reverse routing path, leading from the second network node to the target network node via the first network node, is prevented.
