An intermediate node synchronizer in the intermediate node facilitates time synchronization with its parent node and with the child node. A child node synchronizer in the child node to facilitates time synchronization with the intermediate node. The intermediate node synchronizer exchanges synchronization data with the child node synchronizer to enable the child node to be time synchronized to the intermediate node before the intermediate node is synchronized to its parent node if the intermediate node has not synchronized to its parent node within a predetermined guard time period established for the child node.

Abstract: Techniques for detecting path failures and reducing packet loss as a result of such failures are described for use within a data center or other environment. For example, a source and/or destination access node may create and/or maintain information about health and/or connectivity for a plurality of ports or paths between the source and destination device and core switches. The source access node may spray packets over a number of paths between the source access node and the destination access node. The source access node may use the information about connectivity for the paths between the source or destination access nodes and the core switches to limit the paths over which packets are sprayed. The source access node may spray packets over paths between the source access node and the destination access node that are identified as healthy, while avoiding paths that have been identified as failed.

Abstract: A traffic shifting system is described to shift traffic away from one or more network devices or interfaces. The system ensures that traffic can be safely shifted off of a network device before the shifting occurs. The method is described as broken into several phases, such as a discovery phase, a pre-check phase, a shifting phase, and a post-shift phase. Before shifting occurs, the discovery phase is used to obtain network topology and configuration information. In the pre-check phase, that information is interrogated so that a shifting can be performed without negatively impacting the network. If the pre-check phase is passed, then the network shifting can occur through adjustment of configuration parameters, such as a cost parameter associated with an interface on any devices for which traffic is being shifted. Finally, in the post-shift phase, checks are performed to ensure traffic is shifting away from the network device.

Abstract: Methods and techniques are described for initiating a periodic and triggered location in a target UE. After an LCS Client requests initiation of periodic and triggered location reporting from the UE, two intermediate responses are returned by a network. A first response indicates that the periodic and triggered location request has been received and accepted by the network. A second response indicates that periodic and triggered location has been activated in the UE. Additionally, a periodic and triggered location request may include a maximum event sampling interval and a maximum reporting interval and one or more location triggers. The maximum event sampling interval can limit UE power consumption and the maximum reporting interval can detect when periodic and triggered location is no longer active in a UE. The location triggers may include periodic reporting, reporting using area events or reporting based on UE motion.
