摘要： In one embodiment, a client device queries a location server using a client-selected interface for content retrieval from a content distribution network (CDN), and receives a location attribute from the location server based on a location of the client device. The client device then presents the location attribute to a CDN selector within a first content retrieval request, and may receive a redirection from the CDN selector to a selected content source based on the location attribute. As such, the client device may then initiate a second content retrieval request to the selected content source. In another embodiment, a CDN selector receives a content retrieval request from a client device, and determines that the content retrieval request contains a location attribute indicating a location of the client device. Based on the location attribute, the CDN selector selects a content source, and redirects the client device to the selected content source.
摘要翻译：在一个实施例中，客户端设备使用客户端选择的接口从内容分发网络（CDN）查询内容检索的位置服务器，并且基于客户端设备的位置从位置服务器接收位置属性。然后，客户端设备将位置属性呈现给第一内容检索请求中的CDN选择器，并且可以基于位置属性从CDN选择器接收到所选内容源的重定向。这样，客户端设备然后可以向所选择的内容源发起第二内容检索请求。在另一个实施例中，CDN选择器从客户端设备接收内容检索请求，并确定内容检索请求包含指示客户端设备的位置的位置属性。基于location属性，CDN选择器选择内容源，并将客户端设备重定向到所选择的内容源。

摘要： In one embodiment, techniques are shown and described relating to attack mitigation using learning machines. A node may receive network traffic data for a computer network, and then predict a probability that one or more nodes are under attack based on the network traffic data. The node may then decide to mitigate a predicted attack by instructing nodes to forward network traffic on an alternative route without altering an existing routing topology of the computer network to reroute network communication around the one or more nodes under attack, and in response, the node may communicate an attack notification message to the one or more nodes under attack.
摘要翻译：在一个实施例中，与使用学习机器的攻击缓解有关的技术被示出和描述。节点可以接收计算机网络的网络流量数据，然后基于网络流量数据预测一个或多个节点受到攻击的概率。然后，节点可以通过指示节点在替代路由上转发网络流量而不改变计算机网络的现有路由拓扑以重新路由在被攻击的一个或多个节点周围的网络通信，并且响应于节点可以将攻击通知消息传送给被攻击的一个或多个节点。

摘要： In one embodiment, a node in a network receives communication channel data regarding one or more communication channels available between a particular device in the network and a neighboring device. Each communication channel corresponds to one or more electrical phases over which the particular device can communicate with the neighboring device. The node also receives crosstalk data regarding an amount of crosstalk between the electrical phases over which the particular device can communicate with the neighboring device. The node then generates a routing path for the network based on the received crosstalk and communication channel data.

摘要： In one embodiment, a source routing device (e.g., root device) pre-computes diverse source-routed paths to one or more nodes in a computer network. Upon receiving a particular packet, the device forwards the particular packet on a source-routed first path of the pre-computed diverse paths. In the event the device implicitly detects failure of the first path, then it forwards a copy of the particular packet on a source-routed second path of the pre-computed diverse paths in response. In one embodiment, implicit failure detection comprises seeing a second (repeated) packet with the same identification within a certain time since the first packet, and the second packet is forwarded on the second path. In another embodiment, implicit failure detection comprises not seeing a link-layer acknowledgment returned or receiving an error notification from a node along the broken path, and a stored copy of the particular packet is forwarded on the second path.
摘要翻译：在一个实施例中，源路由设备（例如，根设备）预先计算到计算机网络中的一个或多个节点的不同的源路由路径。在接收到特定分组时，设备在预先计算的不同路径的源路由第一路径上转发特定分组。在设备隐含地检测到第一路径的故障的情况下，其响应地在预先计算的不同路径的源路由第二路径上转发特定分组的副本。在一个实施例中，隐含故障检测包括在自第一分组之后的特定时间内看到具有相同标识的第二（重复）分组，并且第二分组在第二路径上转发。在另一个实施例中，隐含故障检测包括没有看到返回的链路层确认或从断开的路径接收到来自节点的错误通知，并且特定分组的存储副本在第二路径上转发。

摘要： In one embodiment, a device (e.g., path computation device) informs a network management device of a plurality of possible probing profiles, where nodes of a computer network receive the plurality of possible probing profiles from the network management device. Based on determining that particular information is desired from one or more particular nodes of the nodes of the computer network, the device may then select one or more particular probing profiles of the plurality of possible probing profiles based on the particular information, and instructs the one or more particular nodes to probe one or more particular destination nodes according to the one or more particular probing profiles.

摘要： In one embodiment, a Transit Information Bloom Filter (TIBF) signal component is generated for use with a routing protocol control message, the TIBF signal component identifying at least one parent node for a corresponding routing topology. The TIBF signal component is encoded in a generated Bloom filter. The parameters of the generated Bloom filter are based at least on one parent node to be encoded and a desired false positive rate for the Bloom filter. The address for each parent node is also encoded in the Bloom filter.

摘要： In one embodiment, a network device enforces entitlement rules based on call control traffic received. The call control traffic is received at the network device from an application associated with a first user for a second user. The network device determines identification information for the first user and/or the second user. The network device then determines an action to take based on an entitlement policy associated with the first user or the second user. The action is then performed. The network device enforces the entitlement policy without any modification to the application to cause the call control traffic to be routed through the network device. The network device is in the call control path but does not appear to be a participant in the call to the first application.

摘要： In one embodiment, a network device selectively operates according to a sparse multicast mode where the network device stores individual devices interested in one or more multicast groups and distributes corresponding multicast group traffic based on the individual devices. Alternatively, the network device selectively operates according to a dense multicast mode where the network device maintains a list of the one or more multicast groups in which at least one device is interested and distributes corresponding multicast group traffic through broadcasting. By determining one or more resource-related characteristics, the network device may then select between operation in the sparse multicast mode and the dense multicast mode based on the resource-related characteristics.

摘要： In one embodiment, a device in a frequency hopping communication network transmits responsive beacon messages based on adaptive types of responsive beacon message transmission based on a number of received beacon requests within a given time period: the number below a threshold results in synchronized unicast messages; the number above the threshold results in unsynchronized broadcast messages. In another embodiment, the device suppresses unsolicited beacon message transmission based on a density-aware redundancy count of other unsolicited beacon message transmissions from neighboring devices. In another embodiment, the device may transmit unsolicited beacon messages according to an adaptive interval based on stability of the network. In another embodiment, the device may suppress transmission of a beacon request to join the communication network based on a density-aware redundancy count of other beacon requests from neighboring devices, and transmits beacon requests at an adaptive interval that increases in response to each unanswered beacon request.
