Distribution of Time Services Over Networks in a Multi-Network Environment

George A. Shaton

Abstract:	This paper explores reasons for clock synchronization, risks if not performed, and proposes a design for providing clock synchronization in a typical network. In an inter-network environment, it is important to synchronize the clocks in each network device and terminal to a consistent time scale. Moreover, the larger the network, the more important clock synchronization becomes. When dealing with several independent networks, which must exchange data, synchronization is mandatory for efficient transfer of data. The design will present the physical implementation (what hardware is needed), the logical design (selection and use of certain protocols), performance requirements (accuracy, resolution, and measurement), management of the resulting design, security issues, and Domain Name Service (DNS) considerations.
