Timing over Ethernet
The service providers are increasingly turning to Ethernet technologies to provide simple cost effective backhaul solutions to meet their growing data requirements. The asynchronous nature of Ethernet poses some serious problems for service providers migrating from legacy SDH/SONET technologies. Propagation of timing information from a precision reference source is a critical requirement for mobile networks and several technologies are emerging to meet this critical requirement, the two most prominent ones are: Precision Time Protocol (IEEE 1588) and Synchronous Ethernet (SyncE, ITU-T G.8261/2/4).
Licensable Protocol Stacks
The Precision Time Protocol (PTP) is a high precision time protocol for synchronization and is used for multiple applications such as mobile IP backhaul, and for measurement and control systems residing on a local area network. Our Precision Time Protocol (PTP) is a portable implementation of the Precision Time Protocol specified in the IEEE 1588 specification, version 2. Learn More
The SyncE specification defined by the ITU-T G.8264 publication provides the means to use Ethernet to transfer timing (frequency) via the Ethernet PHY layer. Our SyncE is a portable software implementation of the specification. Learn More
