Abstract: A method and apparatus for dynamically transcoding and delivering variable bit rate media files delivers media files to client systems. The media server dynamically transcodes a content file to a bit rate requested by a client using an original content file or other transcoded content files. The media server can dynamically select a segment of a content file to transcode. The file format required by the client is determined and the transcoded segment is formatted to the file format. The formatted segment is delivered to the client.

Abstract: A method and apparatus for delivering variable bit rate media files delivers media files to client systems. The media server can dynamically detect when a client can accept a different bit rate version of a media content. The media server can smoothly switch between different bit rate versions of the media content as it delivers the media content to client systems. A client system can also request different bit rate versions of a media content while it is playing the media content.

Abstract: In one exemplary aspect, an edge-gateway multipath method includes the step of providing an edge device in a local network communicatively coupled with a cloud-computing service in a cloud-computing network. A set of wide area network (WAN) links connected to the edge device are automatically detected. The WAN links are automatically measured without the need for an external router. The edge device is communicatively coupled with a central configuration point in the cloud-computing network. The method further includes the step of downloading, from the central configuration point, an enterprise-specific configuration data into the edge device. The enterprise-specific configuration data includes the gateway information. The edge device is communicatively coupled with a gateway in the cloud-computing network. The communicatively coupling of the edge device with the gateway includes a multipath (MP) protocol.

Abstract: In one aspect, a computerized system useful for implementing a virtual private network (VPN) including an edge device that automatically establishes an Internet Protocol Security (IPsec) tunnel alongside an unsecure Multipath Protocol (MP) tunnel with a gateway device in preparation for a transmission of a secure traffic communication. The edge device has a list of local subnets. The edge device sends the list of local subnets to the gateway during an initial MP tunnel establishment handshake message exchange between the edge device and the gateway device. Each subnet includes an indication of whether the subnet is reachable over the VPN. A gateway device that automatically establishes the IPsec tunnel alongside the unsecure MP tunnel with the edge device. An enterprise datacenter server that comprises an orchestrator module that receives a toggle the VPN command and enables the VPN on the orchestrator. The orchestrator informs the edge device the list of subnets is accessible over the VPN causing the edge device to update the gateway device with a new list of subnets of the edge device that accessible over the VPN.
