A network interface for highly accurate clock synchronization
This paper describes a novel network interface hardware, which enables clock synchronization with sub-μs-range accuracy in network-coupled distributed systems. The basic idea, which works for any packet-oriented data network, is to timestamp data packets at the interface between physical layer transceiver and network controller upon packet arrival and departure. Our particular implementation ta...
متن کاملPhysical Layer Ethernet Clock Synchronization
Clock synchronization is a service widely used in distributed networks to coordinate data acquisition and actions. As the requirement to achieve tighter synchronization accuracy arose, protocols like the Precision Time Protocol introduced hardware timestamping, shifting the point where the timestamp is drawn from the application layer twards the physical layer. However, the spread of the synchr...
متن کاملIntegration of high accurate Clock Synchronization into Ethernet-based Distributed Systems
Emerging networks destined to handle voice, data and Internet Protocol (IP) traffic benefit from a reliable, high accurate distributed time service. In most cases, the end-to-end communication path requires tuning and continuous maintenance to achieve acceptable quality for service integration. Several sources of latency, as they are protocol processing, system transfer rates and frame forwardi...
متن کاملAccurate Clock Synchronization for IEEE 802.11-Based Wireless Networks
Clock synchronization is an essential building block for many control mechanisms used in wireless networks, for example, frequency hopping, power management, and packet scheduling. Although the IEEE 802.11 standard [1, 2, 3, 4] provides a clock synchronization mechanism, it was never designed to support higher-layer network services or mechanisms, and has well-documented problems [5] especially...
متن کاملEmbedded SynUTC and IEEE 1588 clock synchronization for industrial Ethernet
This article deals with two mechanisms for time synchronization over Ethernet networks, the “IEEE 1588 standard for a precision clock synchronization protocol for networked measurement and control systems” and the “synchronized universal time coordinated” technology. It presents a prototype system, which supports both synchronization mechanisms by offering dedicated hardware support on Ethernet...
