Abstract
A method comprising receiving a media signal from a media source at one of one or more media signal receivers, determining an association between the media source and the one of the one or more media signal receivers, sending the association to a state control memory structure, determining one of one or more media signal transmitters associated with a media destination, and sending the first media signal to the media destination utilizing the one of the one or more media signal transmitters associated with the media destination. As a media source may be further utilized as a media destination, the association is utilized to determine the one of the one or more media signal transmitters.
Claims6
A virtual border controller comprising:
- a first interface comprising a plurality of first points of presence to a data communication network;
- a second interface comprising a plurality of second points of presence to the data communication network;
- an anycast address provisioner operable to:
- configure an assignment of a first anycast IP address for data communication between a media source device and the data communication network;
- configure an assignment of a second anycast IP address for data communication between a media destination device and the data communication network;
- configure an assignment of a first one of the first points of presence to communicate with the media source device using the first anycast IP address;
- and
- configure an assignment of a first one of the second points of presence to communicate with the media destination device using the second anycast IP address;
- a state controller;
- and
- logic configured to respond to a misdirection of the data communication by the media source device to a second one of the first points of presence by:
- signaling an indication of the misdirection from the second one of the first points of presence to the state controller;
- changing the assignment of the first one of the first points of presence for the data communication between the media source device and the data communication network using the first anycast IP address to an assignment of the second one of the first points of presence for the data communication between the media source device and the data communication network using the first anycast IP address;
- and
- signaling from the state controller to each one of the first points of presence of the assignment of the second one of the first points of presence for the data communication between the media source device and the data communication network using the first anycast IP address.
