Description: When starting with protocols that work at the upper layers of the network models, each set of data is wrapped inside the next lower layer protocol, similar to wrapping letters inside an envelope. The application creates the data, then the transport layer wraps that data inside its format, then the network layer wraps the data, and finally the link (Ethernet) layer encapsulates the data and transmits it. Each network layer either encapsulates the data stream with additional information, or manages data handling or come part of the connection Platform: |

Description: Introduction to LAN Protocols
This chapter introduces the various media-access methods, transmission methods, topologies, and
devices used in a local-area network (LAN). Topics addressed focus on the methods and devices used in
Ethernet/IEEE 802.3, Token Ring/IEEE 802.5, and Fiber Distributed Data Interface (FDDI). Subsequent
chapters in Part II, “LAN Protocols,” address specific protocols in more detail. Figure 2-1 illustrates the
basic layout of these three implementations. Platform: |

Description: his example demonstrates usage of the mikroC's ethernet communications
library. 3 protocols that are useful for the users are implemented: ICMP
(ping), TCP/IP (VERY simple http) and UDP/IP. It also handles "helper"
protocols that are needed to obtain a proper Internet-like communication:
IP (the basis for TCP/IP and UDP/IP) and ARP (IP-to-MAC address mapping). Platform: |

Description: Within a subsea control system various industrial Ethernet protocols are implemented for process data exchange on the link between topside & subsea. Also, different types of instrumentation networks are used to collect data from sensors & intelligent devices at the seabed. In this
project different protocols & networks shall be evaluated based on criterion from OneSubsea
Processing. As a minimum the following protocols shall be evaluated: Modbus TCP, Ethernet/IP,
and OPC UA for topside - subsea communication. CAN bus (SIIS level II) and IWIS (API 17F)
shall be evaluated for collecting sensor & actuator data to the SCM. The project shall also consist of a practical implementation of industrial protocols. Platform: |
