Abstract: Techniques described herein can perform per-queue network performance measurement mapping, in which per-queue network performance measurements are determined and then mapped back to service level agreement (SLA) classes assigned to use the queues. Network traffic associated with an SLA class can be processed through an assigned router queue. Wide area network (WAN) as well as local performance measurements from the assigned queue can be combined to determine a combined performance measurement associated with the assigned queue. The combined performance measurement can then be mapped or otherwise associated with the SLA class. Similarly, combined performance measurements can be determined for other router queues and mapped or otherwise associated with other SLA classes.

Abstract: A method includes determining a number of drops of a plurality of messages sent to a first node of a plurality of nodes within a mesh network. Based at least in part on the number of drops of the plurality of messages exceeding a threshold number of drops for a time period, decrementing a first rating assigned to the first node to a second rating assigned to the first node. Based at least in part on the second rating being below a rating threshold, determining that the first node is a potentially malicious node. Based at least in part on a first distance to the first node being larger than a distance threshold, identifying that the first node is a malicious node. The method may further include ending communications with the first node.

Abstract: In one embodiment, a technique comprises monitoring data transfer over a radio frequency (RF) link between a first device and a second device in a mesh network where the second device is a descendent node and the first device is a parent node. The technique further transfers the data over a power link communication (PLC) when the RF link is inactive. The method also includes broadcasting, by the second device, RF link availability to at least a third device in the mesh network when the RF link with the first device is inactive where the third device has an active link with the second device and the third device is a descendent node of the second device. The method then includes communicating, between the second device and the third device, through the active RF link.

Abstract: A method includes identifying a potentially malicious node using a rating assigned to nodes within the network and decrementing the rating based on detected dropped messages to identify a potentially malicious node. The malicious node is identified based on location information obtained from the nodes within the network and comparable distances from the potentially malicious node. The method further includes ending communications with the malicious node and selecting a new parent node based on a presumption that any of the plurality of nodes other than the malicious node are non-malicious.
