Design and analysis of real-time multimedia synchronization protocol on the high-speed transport layer

The emerging high-speed computer network makes it possible to communicate using several heterogeneous data types called multimedia. The multimedia transmission in the computer communication network can be performed on the same channel or on several separate channels. Several problems exist with high-speed data transmission using a single channel. To overcome the problems, multiple separate channels are suggested for each data type. The multiple separate channels can be fine-tuned for the characteristics of each data type, but they introduce the synchronization problem if any timing relation exists between channels. The timing relation among packets at the source must be maintained (synchronized) at the destination to deliver meaningful information. It is also believed that the synchronization is to be performed on the transport layer of the protocol stack because the transport layer is the minimal layer for reliable end-to-end communication.; A protocol that can handle the synchronization problem is designed. The protocol is implemented in a transport protocol and simulated using OPNET network simulation tool. The transport protocol is designed based on OSI-TP for future extensions of the high-speed implementation using multiprocessors.
