    摘要： In one example, an Access Point (AP) configures a first mapping of a first cellular network connection to a first local access network group, and further configures a second mapping of a second cellular network connection to a second local access network group. The AP determines whether a user device is authorized to use the first cellular network connection or the second cellular network connection. If the user device is authorized to use the first cellular network connection, the AP associates, for the user device, a first user device identifier with the first local access network group. If the user device is authorized to use the second cellular network connection, the AP associates, for the user device, a second user device identifier with the second local access network group.

    摘要： A first customer edge network device receives an encapsulated packet that includes inner headers comprising source address information for a first service running on a first computing apparatus in a first home cloud and destination address information for a second service running on a second computing apparatus in a second home cloud. The customer edge network device inserts a predetermined portion of bits of a virtual domain identifier of the encapsulated packet into a label to form a virtual domain label for label-based routing. The virtual domain label is appended to the encapsulated packet. The encapsulated packet is sent to a first provider edge network device of a provider network. The first provider edge network device appends an virtual private network label to the encapsulated packet, and sends the encapsulated packet to a provider network device for label-based routing in the provider network.

    摘要： 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.

    摘要： 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.

    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。

    摘要： A source virtual private network (VPN) gateway supports a local source subnet and communicates over a wide area network (WAN) with a destination VPN gateway that supports a local destination subnet. The source VPN gateway receives from the local source subnet an Internet Protocol (IP) packet destined for the local destination subnet, determines a security association (SA) based on a source IP address and a destination IP address of the IP packet, and encapsulates the IP packet with tunnel encapsulation including a tunnel protocol header and a tunnel outer IP header, to produce a clear-text tunnel packet. The source VPN gateway encrypts the IP packet and the tunnel protocol header but not the tunnel outer IP header using an encryption key and a security parameter index for the SA, to produce an encrypted tunnel packet, and tunnels it to the destination VPN gateway over the WAN.
