In one embodiment, a method includes accessing time series data of a wireless communication link between a first node and a second node on a millimeter-wave communications network; determining that an anomaly exists in the time series data; determining an anomaly type for the anomaly by inputting one or more features derived from the time series data into a machine learning module; generating a report comprising an indication that the anomaly exists and a description of the anomaly type, and determining one or more treatments for the determined anomaly.

Apparatuses, methods, and systems for synchronizing nodes of a wireless network are disclosed. One method includes identifying synchronization paths between synchronization reference nodes of the wireless network and each non-reference node of the wireless network, wherein each synchronization path includes one or more wireless hops between the synchronization reference nodes and the non-reference node, determining a number of timing slots needed for supporting each of the identified synchronization paths, and selecting at least one of the synchronization paths between each non-reference node and at least one of the synchronization reference nodes based on a number of wireless hops of each of the identified synchronization paths and the determined number of timing slots needed to support each of the identified synchronization paths.

Apparatuses, methods, and systems for monitoring performance of a wireless network and assigning sectors of nodes of the wireless network are disclosed. A method includes monitoring a performance of links between sectors of wireless nodes of the wireless network, assigning or reassigning sectors of the wireless nodes to operate in a first mode based on the monitored performance of the links, wherein all of the sectors operating in the first mode are configured to transmit signals or simultaneously receive signals, and assigning or reassigning sectors of the plurality of wireless nodes to operate in a second mode based on the monitored performance of the links, wherein all of the sectors operating in the second mode are configured to transmit signals when all of the sectors operating in the first mode are receiving signals, or receive signals when all of the sectors operating in the first mode are transmitting signals.

Wireless network performance monitoring and sector assignment

Disclosed are, inter alia, methods, apparatus, computer-readable media, mechanisms used in one embodiment configured for, and means for, determining packet forwarding information for packets sent from a protocol offload engine in a packet switching device. The protocol offload engine performs the protocol processing for a protocol application (e.g., BGP) running on a separate control plane processing system, and generates packets to be sent to external devices. The protocol offload engine sends these packets to one of the line cards without using the routing information lookup facility of the control plane processing system, thereby, freeing the control plane processing system to use those processing cycles to perform other tasks.

Determining packet forwarding information for packets sent from a protocol offload engine in a packet switching device

A filtered Forwarding Information Base (FIB) (the 'complete local FIB') is used to determine how to forward packets, typically on line cards. The complete local FIB is generated by filtering (i.e., dropping or removing) extraneous entries in the standard global FIB of a router. This smaller FIB is then installed within the memory of a forwarding engine, possibly implemented as a single application-specific integrated circuit (ASIC), for use in determining how to forward packets, with the router forwarding packets accordingly.
