		+	The Internet is not naturally suitable for real-time traffic since the shared datagram property. Moreover, Internet Protocol (IP) has some fundamental problems in transmitting real-time data. Therefore, some more protocols are developed to support the quality of service(Qos) for streaming media applications.[3]

	=== RTP ===		=== RTP ===
		+
		+	'''The Real-time Transport Protocol(RTP)''' is a transport protocol for delivering audio, video and other real-time applications over the internet. RTP use timestamping, sequence numbering, and other mechanisms to provide end to end transport for real-time applications over the datagram network.[3] The information is stored in the header of a RTP packet.
		+
		+	The RTP header size is 96 bits.
		+
		+	'''0-1''' indicate the version of the protocol.
		+
		+	'''2''' indicates if there are extra padding bytes at the end of the RTP packet.
		+
		+	'''3''' indicates if the externsion header is used.
		+
		+	'''4-7 '''indicate the number of source identifiers.
		+
		+	'''8''' is used as the application level to indicate if the data carrying have relevance with the application.
		+
		+	'''9-15 '''indicate the payload format as well as encoding method.
		+
		+	'''16-31''' are used to determine the correct order of packets(Sequence numbering).
		+
		+	'''32-63''' are timestamping which will be used by the receiver to reconstruct the original timing(Timestamping).
		+
		+	'''64-95''' indicate the synchronization source.

	=== RTCP ===		=== RTCP ===
		+
		+	'''Real-time Transport Control Protocol(RTCP)''' is the control protocol designed to work with RTP because RTP doesn't have error correction or flow control functionality.
		+
		+	There are several types of RTCP packets:
		+
		+	''Receiver report packet'' contains quality feedback about the data delivery.
		+
		+	''Sender report packet'' contains a sender information section.
		+
		+	''Source description packet'' contains the information of sources.
		+
		+	''Application specific packet'' contains the experiment of new applications and new features.
