dcterms:description
Node synchronization can be implemented in an Ethernet network using time protocols; e.g. IEEE 1588. Active network components like switches and routers influence a precision of the synchronization because they affect the packet delay in the network. Therefore, the delay is not constant and also the delay in one direction is not equal to the delay in the opposite direction. This paper presents a low-cost device that can precisely measure the packet delay in both communication directions and, at the same time, calculate network parameters; e.g. the packet delay variation, the path asymmetry and dependency of the delay in opposite directions. Measured values can be used to determine the usability of the network for the IEEE 1588 implementation and to predict the quality of the synchronization in a network. These measurements are important to achieve a precise synchronization in a low-cost network infrastructure.
