Oregano Systems‘ syn1588® PTP Stack offers a complete implementation of the protocol stack for the IEEE1588-2008 standard. The syn1588® PTP Stack is a well proven, reliable and portable software. Its outstanding functionality is verified regularly on ISPCS plugfests and SMPTE Interops.
Oregano Systems offers a protocol stack - the syn1588® PTP Stack - which is fully compatible to the IEEE1588 Standard for the Precision Clock Synchronization Protocol. The syn1588® PTP Stack is tested for compatibility in environments with stacks of other proveniences on several IEEE1588 plugfests.
syn1588® PTP Stack – The Big Picture
Every IEEE1588 implementation requires two parts:
- hardware real-time task
- software complex protocol task
The hardware performs in real-time the follwing basic functions:
- packet matching
- accurate clock
The software performs without any real-time constraints the follwing basic functions:
- protocol handling
- user interface
- configuration of modes
The syn1588® PTP Stack is such an implementation.
The syn1588® PTP Stack’s software architecture is partitioned into the PTP library and the PTP application. The library executes a protocol engine which processes PTP messages and drives a control loop to synchronize a (hardware) clock. The engine is designed as a state machine according to the full master/slave state protocol of the IEEE1588-2008 standard.
The PTP application incorporates all parts outside the IEEE1588-2008 standard as well as all platform/operating system dependent functions (logging, network access, configuration, user interaction). The complete syn1588® PTP Stack is implemented in native C/C++ with a focus on using almost only platform independent functions and libraries (Portable Operating System Interface- POSIX, Adaptive Communication Environment – ACE). Thus, reusing the library or porting it to new platforms is easy and straightforward.
