    Abstract: A slave resource router may receive a client request. The slave resource router may be the nearest representation of an Anycast IP address in a network to a client sending the client request in the network. The slave resource router may then determine that the slave resource router has been authorized to cache content for a delivery service corresponding to the client request. Next, the slave resource router may determine that content corresponding to the client request is cached locally in a blind cache. Then the slave resource router may provide the client with the content from the blind cache.

    Abstract translation: 从属资源路由器可以接收客户端请求。 从属资源路由器可以是在网络中向在网络中发送客户端请求的客户端的任播IP地址的最近表示。 从属资源路由器然后可以确定从属资源路由器已被授权缓存对应于客户机请求的传送服务的内容。 接下来，从属资源路由器可以确定与客户端请求对应的内容在本地缓存在盲缓存中。 然后从属资源路由器可以向客户端提供来自盲缓存的内容。

    Abstract: Techniques are presented for optimizing secure communications in a network. As disclosed herein, a key server is configured to provision a plurality of routers that are part of a virtual private network. The key server selects a counter value that is part of a security association and calculates a key value. The key server sends the key value, together with the security association, to the plurality of routers that are part of the virtual private network to enable them to exchange encrypted packets with each other in the virtual private network using the key value and the security association. The key server then increments the counter value to a value within a range of counter values capable of being predicted by the plurality of routers that received the key value.

    Abstract: Various techniques that allow group members to detect the use of stale encryption policy by other group members are disclosed. One method involves receiving a message from a first group member via a network. The message is received by a second group member. The method then detects that the first group member is not using a most recent policy update supplied by a key server, in response to information in the message. In response, a notification message can be sent from the second group member. The notification message indicates that at least one group member is not using the most recently policy update. The notification message can be sent to the key server or towards the first group member.

    Abstract: 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.

    Abstract translation: 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内的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。
