Abstract: The present invention provides common protocol architecture and methods for transmitting data between different network protocols and a common protocol packet. The common protocol architecture comprises an application layer; a common protocol layer positioned under the application layer, the common protocol layer enabling data communications between the different protocols; a presentation layer positioned under the common protocol layer; a session layer positioned under the presentation layer; a transport layer positioned under the session layer; a network layer positioned under the transport layer; a data link layer positioned under the network layer; and a physical layer positioned under the data link layer. The common protocol packet comprises a common protocol header with information about a packet and a payload with the contents of data. By designing the common protocol layer and the common protocol packet accepting various.

Abstract: The present invention relates to a communication system architecture which can perform integrated processing of different network protocols and multimedia traffics. The communication system for integrated processing of different network protocols and multimedia traffics comprises a common packet; a common packet switch; a plurality of channels; a common bus; a common protocol platform; an external network protocol converter; and an internal network protocol converter. Thus, the present invention can process traffics rapidly embodied by mean of hardware, and easily perform various QoS, traffic control, and so on by designing a unified common platform with an open architecture. In addition, the present invention can be used for digital consumer devices in building networks and home networks or various digital appliances classified as Internet information appliances, and for control systems such as a home gateway, a home server, an STB, a home station and so on.
