摘要： In one embodiment, a particular node in a primary DAG receives a distributed message from distributing nodes, and from this, deterministically selects a distributing node as a distributing parent in a secondary DAG from which distributed messages are to be received. The particular node may then inform the deterministically selected distributing parent that it is being used by the particular node as its distributing parent, and if the selected distributing parent is not the particular node's primary DAG parent, then the primary DAG parent is informed that it need not send distributed messages for the particular node. In another embodiment, a distributing node continues to repeat distributed messages in response to receiving notification that it is being used as a distributing parent, and if a primary DAG parent, prevents the repeating in response to receiving a notification from all of its child nodes that it need not send distributed messages.

摘要： In one embodiment, one or more routing update parameters may be set for and propagated to nodes of a directed acyclic graph (DAG) in a computer network, the routing update parameters indicative of when to perform a corresponding routing update operation. A decision node (e.g., a root node of the DAG, application in a head-end, etc.) may gather network statistics of the DAG during operation based on the routing update parameters, and may accordingly determine at least one adjusted routing update parameter based on the gathered network statistics. This adjusted routing update parameter may then be propagated to the nodes of the DAG, such that the nodes operate according to the (adaptively) adjusted routing update parameter.

摘要： In one embodiment, a particular node (e.g., root node) in a directed acyclic graph (DAG) in a computer network may identify a low-contact (e.g., wireless) node in the DAG that is at risk of having an invalid path when attempts are made to reach the low-contact node. In response, the particular node may identify neighbors of the low-contact node, and may establish a multicast tree from the particular node to the low-contact node through a plurality of the neighbors to reach the low-contact node. When sending traffic to the low-contact node, the particular node sends the traffic on the multicast tree, wherein each of the plurality of neighbors attempts to forward the traffic to the low-contact node. In another embodiment, the low-contact node itself indicates its status to the particular/root node, along with its list of neighbors in order to receive the multicast traffic.

摘要： In one embodiment, a particular node joins a directed acyclic graph (DAG) in a computer network at a parent node, and determines its grade based on a topology of the DAG, the grade lower than the parent node and higher than any child nodes of the particular node. In response to detecting a trigger for a routing change in the DAG, the particular node delays the routing change based on the grade such that the delay is longer than a first associated delay of any of the child nodes and shorter than a second associated delay of the parent node. Upon expiration of the delay, the particular node may determine if the trigger for the routing change is still valid, and if valid, performs the routing change.

摘要： Techniques are provided to improve the performance of wireless devices that serve wireless client devices in a wireless network in the presence of narrowband interference. The wireless device that serves wireless client devices in the wireless network receives energy in a plurality of channels of a frequency band. The received energy is analyzed for occurrence and type of interference in each channel. A quality metric is generated for each channel incorporating the occurrence and type of interference detected in the channel. For each channel, a bias value against selection of the channel is assigned based on whether narrowband interference is present in the channel. The bias value for each channel is applied to the quality metric for the channel to produce an adjusted quality metric for each channel. A channel is selected based on the adjusted quality metric for each of the plurality of channels.

摘要： A method for evaluating number of additional admissible calls for use in call admission control includes tracking a percentage of channel busy time and transmission time of downlink and uplink voice packets, receiving a call admission request, and calculating the number of admissible calls. The number of admissible calls is calculated based on a channel bandwidth requirement determined from the percentage of channel busy time and a voice packet queuing requirement determined from the transmission time of downlink and uplink voice packets. The call admission request is approved if the number of admissible calls is greater than one and rejected if the number of admissible calls is less than one.

摘要： Techniques are provided to determine channel assignments for wireless access point (AP) devices in a wireless local area network (WLAN). From each of a plurality of AP devices operating at least one of a plurality of channels in the WLAN, wireless activity data is received that represents activity in each channel associated with signals of devices operating in the WLAN and associated with signals and energy from devices that are not operating in the WLAN as detected by the AP devices by receiving radio frequency energy in each of the plurality of channels. During a channel plan evaluation session, the wireless activity data is evaluated for multiple ones of the plurality of access point devices to determine whether the channel on which an access point device operates should be changed such that a decision to change the channel for at least one access point is limited to a localized region of the wireless network and does not necessarily affect a channel change decision for access points outside of the localized region of the wireless network. The channel on which the at least one access point device operates is changed or assigned based on the evaluation. In one form, the wireless activity data is a single metric that is derived from multiple pieces of data, each representing a different component of wireless activity determined by an AP device to be occurring in a channel.
