    摘要： Methods and apparatus to communicatively couple virtual private networks to virtual machines within distributive computing networks are disclosed. A disclosed example method includes receiving a request to provision a virtual machine from a virtual private network, determining a host for the virtual machine within a distributive computing network, creating the virtual machine within the host, communicatively coupling the virtual machine to a virtual local area network switch within the distributive computing network, configuring a portion of a router to be communicatively coupled to the virtual machine via the virtual local area network switch by specifying an address space within the router associated with at least one of the virtual machine or the virtual private network communicatively coupled to the router, and communicatively coupling the portion of the router to the virtual private network.

    摘要： Distribution of content between publishers and consumers is accomplished using an overlay network that may make use of XML language to facilitate content identification. The overlay network includes a plurality of routers that may be in communication with each other and the publishers and consumers on the Internet. Content and queries are identified by content descriptors that are routed from the originator to a nearest router in the overlay network. The nearest router, for each unique content descriptor, generates a hash identification of the content descriptor which is used by remaining routers in the overlay network to provide the appropriate functions with respect to the content descriptor. In particular, this allows all routers in the overlay network except the nearest router to properly route content without processing every content descriptor.

    摘要： A method and system are described to multicast with an adaptive dual state. The system receives multicast traffic over a membership tree including a first plurality of nodes connected in a first topology destined for a plurality of multicast members of a first multicast group. Next, the system determines a rate of multicast traffic that exceeds a predetermined threshold based on the receiving the multicast traffic. Next, the system generates a dissemination tree including a second plurality of nodes connected in a second topology to reduce a number of hops to communicate the multicast traffic to the plurality of multicast members of the first multicast group. Finally, the system forwards the multicast traffic to the plurality of multicast members of the first multicast group over the dissemination tree.

    摘要： A method for processing media content requests includes receiving, at a multimedia distribution computing device, a request for a media stream to be provided to a media device. The method includes determining, at the multimedia distribution computing device, whether media content of the media stream is for time-shifted viewing. The method includes sending a unicast transmission including at least a portion of the media content to the media device when the media content is not determined to be for time-shifted viewing. The method includes joining the media device to a multicast group associated with the media stream without sending the unicast transmission to the media device when the media content is determined to be for time-shifted viewing.

    摘要： Systems and methods of multicast configuration are provided. A particular method includes detecting a failure in the data network at a first node of a data network. The method also includes determining an alternate route from the first node to a data source of the data network. The alternate route includes a second node as an upstream node. The method further includes determining whether the alternate route would create a loop in the data network. The method includes setting a state of the first node to a waiting-to-join the second node state when the alternate route would create a loop.
