US Patent 7961739 Systems and methods for voice over multiprotocol label switching

A method, system, and computer-readable medium for transmitting voice over multiprotocol label switching is provided. A packet that includes layer 3 and layer 4 headers is received. A label that identifies a label switched path in the packet is inserted, and a stream identifier is generated. The stream identifier is associated with at least a portion of content of the layer 3 and layer 4 headers. The layer 3 and layer 4 headers are removed from the packet, and the stream identifier is inserted into the packet. Additionally, methods, systems, and a computer-readable medium for processing a voice over multiprotocol label switching frame that excludes layer 3 and layer 4 headers are provided.
