A hybrid passive optical network (“PON”) includes a time-division multiplexing (“TDM”) optical line terminal (“OLT”) and a wavelength-division multiplexing (“WDM”) OLT. The TDM OLT communicates with a first group of customer premises (“CPs”) via TDM signals while the WDM OLT communicates with a second group of CPs via WDM signals. A remote node power splitter is coupled to receive the TDM and WDM signals and broadcast both the TDM signals and the WDM signals on all of its ports facing towards the CPs. Optical filters are disposed between the remote node power splitter and the second group of CPs. Each optical filter is configured to pass a sub-group of the WDM signals while blocking other WDM signals such that each of the second group of CPs receives its own allocation of WDM signals but does not receive WDM signals allocated to other CPs of the second group of CPs.

Various multi-lane ADCs are disclosed that substantially compensate for impairments present within various signals that result from various impairments, such as phase offset, amplitude offset, and/or DC offset to provide some examples, such that their respective digital output samples accurately represent their respective analog inputs. Generally, the various multi-lane ADCs determine various statistical relationships, such as various correlations to provide an example, between these various signals and various known calibration signals to quantify the phase offset, amplitude offset, and/or DC offset that may be present within the various signals. The various multi-lane ADCs adjust the various signals to substantially compensate for the phase offset, amplitude offset, and/or DC offset based upon these various statistical relationships such that their respective digital output samples accurately represent their respective analog inputs.
摘要:
Energy proportional solutions are provided for computer networks such as datacenters. Congestion sensing heuristics are used to adaptively route traffic across links. Traffic intensity is sensed and links are dynamically activated as they are needed. As the offered load is decreased, the lower channel utilization is sensed and the link speed is reduced to save power. Flattened butterfly topologies can be used in a further power saving approach. Switch mechanisms are exploit the topology's capabilities by reconfiguring link speeds on-the-fly to match bandwidth and power with the traffic demand. For instance, the system may estimate the future bandwidth needs of each link and reconfigure its data rate to meet those requirements while consuming less power. In one configuration, a mechanism is provided where the switch tracks the utilization of each of its links over an epoch, and then makes an adjustment at the end of the epoch.
摘要:
A system obtains assurance by a content provider that a content control key is securely stored in a remote security module for further secure communications between the content provider and the security module. A security module manufacturer, which has a pre-established trustful relation with the security module, imports a symmetric transport key into the security module. The symmetric transport key is unique to the security module. The content provider shares the symmetric transport key with the security module manufacturer. The content provider exchanging messages with the security module through a security module communication manager in order to get the proof that the security module stores the content control key. At least a portion of the messages exchanged between the content provider and the security module are protected using the symmetric transport key. The symmetric transport key is independent of said content control key.

A protocol for operation of wireless devices enables a wireless device to remotely and securely invoke a service on a target wireless device without requiring the user of the target wireless device to take any action and without requiring the target wireless device to use power unnecessarily. Mutual authentication is executed while the target wireless device remains in a low power discoverable mode. The discoverable mode includes discovery windows separated by inactive windows when the radio of the target wireless device is powered down.
