    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: Techniques are presented for optimizing secure communications in a network. A first router receives from a second router an encrypted packet with an unknown security association. The first router examines the packet to determine whether the counter value is in a range of predicted counter values. Additionally, a key server is configured to provision 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 enable routers to exchange encrypted packets with each other in the virtual private network using the key value and the security association. The key server increments the counter value to a value within a range of counter values capable of being predicted by the routers.

    Abstract: A system and methods for providing dynamic transcoder rate adaption for an adaptive bit streaming function is described. In a first embodiment, a client may select from all available bit rates during the encoding session, wherein the bit rates are provided to the client via a manifest file from a media gateway. In a second embodiment, a subset of the bit rates are provided to the client, from which a client chooses a selected bit rate. The encoding session continues until a request for a new bit rate is received from the client, at which time a new subset of bit rates are generated. This new subset of bit rates is presented to the client, and this loop continues until the termination of the encoding session.

    Abstract: A method is provided in one example embodiment and includes receiving at a node of a transitive IP network a data packet including a Network Services Header (“NSH”); accessing by the transitive IP network node context contained in the NSH, wherein the context may be used by the transitive IP network node to perform an enhanced network service in connection with the received data packet; performing by the transitive IP network node the enhanced network service in connection with the received data packet using the accessed context; and, subsequent to the performing, forwarding the received packet to a next node.

    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。
