Abstract: A virtual provider edge server may include different modules that implement a hybrid provider edge. A flow detection module may sample received traffic through a server and adaptively detect flows to be offloaded. An offloading module may be an SDN controller that controls the flow tables of a switch that data traffic is offloaded to.

Abstract: Aspects of the subject disclosure may include, for example, a processing system of a communication node routing data packets for a first streaming session between a viewer node of a plurality of viewer nodes and a content streaming server through the communication node without interrupting delivery of content data to the viewer node, establishing a second streaming session with the content streaming server to receive the content data, creating a first and second replacement connections by imitating a connections with the content streaming server and the viewer node, receiving a control packet over the second streaming session from the content streaming server, and splitting the first streaming session responsive to receiving the control packet. Other embodiments are disclosed.

Abstract: Aspects of the subject disclosure may include, for example, a virtual processing system initiating a first streaming session with a content streaming server to receive content data, creating a first transport connection with a viewer streaming the content data in a second streaming session with the content streaming server by imitating a transport connection of the content streaming server with the viewer, creating a second transport connection with the content streaming server by imitating a transport connection of the viewer with the content streaming server, splitting the first streaming session between the content streaming server and the viewer, and streaming the content data to the viewer. Other embodiments are disclosed.

Abstract: A multimedia conferencing service uses accessible-forwarding-plane network elements such as OpenFlow® controllers and OpenFlow®-enabled switches. A conferencing server receives a conference subscription request including a network address of a L2/L3 signaling server, and connects to an accessible-forwarding-plane controller to control an accessible-forwarding-plane switch. Flow tables and group tables are managed to classify traffic with minimum table usage and update frequency. Media channels are established between clients through the OpenFlow®-enabled switches, relieving bottlenecks at the conferencing server.
