SYSTEM AND METHOD FOR TRANSFERRING DIFFERENT TYPES OF STREAMING AND PACKETIZED DATA ACROSS AN ETHERNET TRANSMISSION LINE USING A FRAME AND PACKET STRUCTURE DEMARCATED WITH ETHERNET CODING VIOLATIONS

摘要

A communication system, network, interface, and port architecture are provided for transporting different types of data across a network. The network can be arranged by connecting the ports in a daisy-chain fashion to achieve a ring architecture or topology. The network forwards data according to a specific network protocol, and nodes among the network can use a recovered clock from the bitstream to drive the transmitter and create a synchronous network even thought the network can receive Ethernet packets which are typically targeted for an asynchronous network. Non-compliant data, such as Ethernet data, can be sent as packets within a frame structure. The frame is synchronized to Ethernet coding violations used to signal the beginning of each frame, and each packet can be immediately followed by a packet coding violation. The frame and packet coding violations are represented as a sequence of 4B/5B codes that are not valid codes and, therefore, not present as Ethernet encoded data.
