摘要： In one embodiment, a QoS manager process that receives, at an EzVPN server device, connection speed data from an EzVPN client device. In addition, the QoS manager process processes, at the EzVPN server device, the connection speed data to determine a QoS policy for a communications session between the EzVPN client device and the EzVPN server device. Furthermore, the QoS manager process applies, at the EzVPN server device, the QoS policy to the communications session between the EzVPN client device and the EzVPN server device as determined by the processing of the connection speed data.

摘要： In one embodiment, a head-end node of a tunnel, relative to a tail-end node, receives a trace request, and in response, generates an out-of-tunnel trace request based on the trace-request. The trace request is transmitted in-tunnel to the tail-end node, while also transmitting the out-of-tunnel trace request to at least one subsequent node. The head-end node may then receive a trace response from the tail-end node based on the in-tunnel trace request, as well as a trace response from each of the subsequent nodes based on the out-of-tunnel trace request.

摘要： In one embodiment, a rekey distribution process transmits, from a key server, a multicast probe message intended to be received by at least one group member device. The rekey distribution process also receives, at the key server, an acknowledgement message from each group member device that received the multicast probe message. In turn, the rekey distribution process transmits, from the key server, a multicast rekey data message intended to be received by each group member device from which the key server received an acknowledgment message. Furthermore, the rekey distribution process transmits, from the key server, a unicast rekey data message to each group member device from which the key server did not receive an acknowledgment message.

摘要： A method, system, and computer program product for dynamically updating a routing table in a virtual private network including a concentrator with a routing table and one or more security associations is provided. A change is identified in the virtual private network, and related network information is also identified. A notification update message is created, including (i) a type of change to be made to the routing table based on to the identified change and (ii) the related network information. The notification update message is sent to the concentrator, which updates the routing table according to the notification update message. During the updating of the routing table of the concentrator, current security associations of the virtual private network tunnel are maintained.

摘要： A method is disclosed for transmitting system management requests to computer systems along a network path using a network control protocol, such as RSVP. For example, an originating node may send a single system management request along a path to a destination node using a network control protocol. Each computer system along the network path may analyze the network control protocol message to determine whether the message contains a system management request. If a system management request is found in the message, the computer system may perform the system management function identified in the request, and respond to it.

摘要： A method, apparatus and computer program product for providing scalability for channel change requests in a Switched Digital Video system is presented. A request for a channel change is received. A determination is made regarding whether a channel requested by the request for a channel change is currently being provided to the settop box. When the channel requested by the request for a channel change is being provided to the settop box then the request for a channel change is buffered for transmission at a later time. When the channel requested by the request for a channel change is not being provided to the settop box then the request for a channel change is immediately sent to an SDV server in communication with the settop box.
