摘要： In one embodiment, a wireless transmitting node in a frequency hopping wireless network may determine whether a packet can be transmitted within a particular timeslot of a frequency hopping sequence based on a length of the packet. If unable to transmit the packet within the particular timeslot, the transmitting node extends the particular timeslot into a subsequent timeslot to allow transmission of the packet within the extended timeslot at a frequency associated with the particular timeslot. Once the extended timeslot ends, the transmitting node and receiving node hop frequencies into the subsequent timeslot to synchronize with the rest of the network that already hopped at the conventional rate. In another embodiment, a wireless receiving node may also extend the particular timeslot into a subsequent timeslot to allow reception of a packet that would extend beyond the particular timeslot, and may hop frequencies upon expiration of the extended timeslot.
摘要翻译：在一个实施例中，跳频无线网络中的无线发射节点可以基于分组的长度来确定是否可以在跳频序列的特定时隙内发送分组。如果不能在特定时隙内发送分组，则发送节点将特定时隙扩展到随后的时隙中，以允许以与特定时隙相关联的频率在扩展时隙内传输分组。一旦扩展时隙结束，发射节点和接收节点将频率跳到随后的时隙中，以与以常规速率跳过的网络的其余部分同步。在另一个实施例中，无线接收节点还可以将特定时隙扩展到随后的时隙中，以允许接收超出特定时隙的分组，并且可以在扩展时隙到期时跳频。

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.
摘要翻译：在一个实施例中，安全设备接收由第一设备发送到第二设备的分组发送的分组的一个或多个第一唯一标识，由第二设备将第二设备的相应确认声称地返回给第二设备。安全设备还从第一设备接收由第二设备接收的分组并由第二设备确认的分组的一个或多个第二唯一标识符给第一设备。通过比较第一和第二唯一标识，安全设备然后可以基于第一和第二唯一标识是否完全匹配来确定由第一设备接收到的确认是否真的从第二设备返回。

摘要： In one embodiment, a node in a computer network detects a misbehaving node in the computer network based on the misbehaving node acting in violation of one or more rules. As such, the node communicates information regarding the misbehaving node to a network management system (NMS), and then may receive isolation instructions from the NMS regarding how to isolate the misbehaving node from the computer network. Accordingly, the node may perform the isolation instructions. In another embodiment, the NMS receives the communicated information regarding the misbehaving node, and determines whether the misbehaving node should be isolated based on the communicated information. If so, then the NMS determines isolation instructions regarding how to isolate the misbehaving node from the computer network, and transmits them to one or more nodes in the computer network, accordingly.
摘要翻译：在一个实施例中，计算机网络中的节点基于违反一个或多个规则而行为不正当行为节点检测计算机网络中的行为不正的节点。因此，节点将关于不良行为节点的信息传送到网络管理系统（NMS），然后可以从NMS接收关于如何将不良行为节点与计算机网络隔离的隔离指令。因此，节点可以执行隔离指令。在另一个实施例中，NMS接收关于不良行为节点的所传送的信息，并且基于所传送的信息来确定是否应该隔离不良行为节点。如果是这样，则NMS确定关于如何将不良行为节点与计算机网络隔离的隔离指令，并相应地将它们发送到计算机网络中的一个或多个节点。

摘要： In one embodiment, a particular field area router (FAR), in a local computer network (e.g., a mesh network) having a plurality of FARs, advertises a common subnet prefix assigned to the local computer network into a global computer network. Each of the plurality of FARs of the local computer network is configured to accept any traffic destined to the local computer network, and a tunnel overlay is built among the plurality of FARs. Upon receiving a packet at the particular FAR destined to a particular device in the local computer network, and in response to the particular FAR not having a host route to the particular device, it forwards the packet on the tunnel overlay to another of the plurality of FARs of the local computer network.
摘要翻译：在一个实施例中，具有多个FAR的本地计算机网络（例如，网状网络）中的特定场区域路由器（FAR）将分配给本地计算机网络的公共子网前缀通告给全局计算机网络。本地计算机网络的多个FAR中的每一个被配置为接受去往本地计算机网络的任何流量，并且在多个FAR之间建立隧道覆盖。一旦在特定的FAR上收到一个目的地是本地计算机网络中的特定设备的分组，并且响应于特定的FAR没有到该特定设备的主机路由，它将隧道覆盖上的分组转发到多个本地计算机网络的FAR。

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.
