Abstract: Various embodiments for implementing a multimedia conference session utilizing a software defined networking (SDN) architecture are described. Various embodiments include an SDN media controller (SDNMC) that initially receives a request to establish a multimedia conferencing session between a plurality of endpoints. Based on the request, the SDNMC allocates at least one virtual media address for the multimedia conferencing session and creates a stream table based on the at least one virtual media address. After processing the request, the SDNMC transmits one or more SDN commands that includes the stream table to the SDN controller. The SDN controller receives the SDN commands at a northbound interface and sends one or more SDN instructions to one or more SDN devices at a southbound interface. The SDN devices update their routing information in order to relay media traffic corresponding to the virtual media address directly between the endpoints.

Abstract translation: 描述了利用软件定义的网络（SDN）架构实现多媒体会议会话的各种实施例。 各种实施例包括最初接收在多个端点之间建立多媒体会议会话的请求的SDN媒体控制器（SDNMC）。 基于该请求，SDNMC为多媒体会议会话分配至少一个虚拟媒体地址，并基于该至少一个虚拟媒体地址创建一个流表。 在处理该请求之后，SDNMC将包含流表的一个或多个SDN命令发送到SDN控制器。 SDN控制器在北向接口接收SDN命令，并向南向接口的一个或多个SDN设备发送一个或多个SDN指令。 SDN设备更新其路由信息，以便直接在端点之间中继对应于虚拟介质地址的媒体流量。
