Design and Implementation of IEC 61162-4 based TLI Protocol for e-Navigation on Ship

In this paper, we propose a transmission algorithm of the TLI protocol of the IEC 61162-4 standard to perform the e-Navigation on ship, and we design and implement the TLI protocol according to the proposed algorithm. The implemented protocol is a TCP/IP based protocol, and is a network protocol with the MAU and LNA components proposed in the IEC 61162-4 standard. In addition, it makes a data transmission over the network architecture based on client/server network model. In the implemented protocol, there are a communication between the MAU and the LNA in one host, and also a communication between the LNA and the LNA in each other hosts. In order to provide a variety of service in a host, every client host has a LNA and multiple MAUs. According to the standard specification and the proposed transmission algorithm, we designed and implemented the TLI protocol using object-oriented mechanism. We carried out the experiment under a simple network model similar to real ship environment, and confirmed that it successfully transmits and receives data between the hosts.
