摘要： In one embodiment, a security device receives one or more first unique identifications of packets sent by a first device to a second device for which a corresponding acknowledgment was purportedly returned by the second device to the first device. The security device also receives one or more second unique identifications of packets received by the second device from the first device and acknowledged by the second device to the first device. By comparing the first and second unique identifications, the security device may then determine whether acknowledgments received by the first device were truly returned from the second device based on whether the first and second unique identifications exactly match.

摘要： In one embodiment, a node may determine a trigger for establishing transmission priority on a path through a shared-media communication network for priority traffic to a particular node. As such, the node may generate a path clear message (PCM) that would instruct one or more receiving nodes along the path to suspend transmission for traffic other than the priority traffic for a specified duration, and also to transmit a local non-repeated distributed message to one or more neighbor nodes of each respective receiving node, the local non-repeated distributed message to instruct the neighbor nodes to suspend transmission for the specified duration. After transmitting the PCM along the path to the particular node to establish the transmission priority for the priority traffic along the path through the shared-media network, the priority traffic may be transmitted to the particular node along the path during the transmission priority.
摘要翻译：在一个实施例中，节点可以确定用于在通过共享媒体通信网络的路径上建立传输优先级的触发，以用于到特定节点的优先流量。因此，节点可以生成路径清除消息（PCM），其将指示沿着该路径的一个或多个接收节点在指定的持续时间内暂停除优先级业务之外的业务的传输，并且还发送本地非重复分布式消息到每个相应接收节点的一个或多个邻居节点，该本地非重复分布式消息指示相邻节点在指定持续时间内暂停传输。在沿着路径发送PCM到特定节点以建立沿着通过共享媒体网络的路径的优先业务的传输优先级的情况下，优先业务可以在传输优先级期间沿着路径发送到特定节点。

摘要： In one embodiment, a particular node in a computer network, that is, one receiving electrical power from a grid source, may determine routing metrics to a plurality of neighbor nodes of the particular node in the computer network. In addition, the node also determines power grid connectivity of the plurality of neighbor nodes. Traffic may be routed from the particular node to one or more select neighbor nodes having preferred routing metrics, until a power outage condition at the particular node is detected, at which time the traffic (e.g., last gasp messages) may be routed from the particular node to one or more select neighbor nodes having diverse power grid connectivity from the particular node. In this manner, traffic may be routed via a device that is not also experiencing the power outage condition.

摘要： In one embodiment, a device in a computer network receives a particular packet associated with a transmission attempts value, the associated transmission attempts value indicative of a first number of times a transmitter has attempted to transmit the particular packet. In response, the device increases by one a stored successful attempts value stored at the device, the stored successful attempts value indicative of a second number of times the device has received the same particular packet. As such, a reachability rate of a link from the transmitter to the device may be determined based on comparing the associated transmission attempts value to the stored successful attempts value.
摘要翻译：在一个实施例中，计算机网络中的设备接收与传输尝试值相关联的特定分组，相关联的传输尝试值指示发射机尝试发送特定分组的第一次数。作为响应，设备增加存储在设备中的一个存储的成功尝试值，所存储的成功尝试值指示设备已经接收到相同特定分组的第二次数。因此，可以基于将相关联的传输尝试值与存储的成功尝试值进行比较来确定从发射机到设备的链路的可达性速率。

摘要： In one embodiment, a router maintains a communication session between a local terminal unit and a remote terminal unit, the local terminal unit interconnected to the router over a local serial data link, and the remote terminal unit interconnected to the router over an Internet Protocol (IP) session via a remote router and a corresponding remote serial data link. The router may then monitor a state of the local serial data link, and communicates this state with the remote router over the IP session, as well as a remote state of the remote serial data link. The router may then correspondingly control the state of the local serial data link to match the remote state of the remote serial data link.

摘要： A multicast message may be distributed by receiving, at a first node in a multicast network, a multicast message from a parent node of the first node. The multicast message is transmitted to child nodes of the first node in the multicast network. A population of the child nodes to which the multicast message was transmitted is accessed and acknowledgement messages which reveal child nodes that are among an acknowledging subset of less than all of the child nodes of the first node are received. Child nodes revealed by the received acknowledgement messages are compared with child nodes determined to be among the population of child nodes to which the multicast message is expected to be received. Based on results of the comparison, a compressed non-acknowledging subset is identified and transmitted to the parent node.

摘要： In one embodiment, a quality of one or more links of a particular node in a communication network may be determined, and then whether the quality of the one or more links is below a threshold may also be determined. In response to determining that the quality of at least one of the one or more links is above the threshold, a select one of the at least one of the one or more links with quality above the threshold may be utilized for communication with the particular node. Conversely, in response to determining that the quality of each of the one or more links is below the threshold, multi-path forwarding over a plurality of links of the particular node may be utilized for communication with the particular node.
