Scalability
The TTEthernet product family supports bandwidths of 10, 100 Mbit/s, 1 Gbit/s, and higher, which guarantees that one technology is capable to support different speeds. The scalable network topology offers the opportunity to select star, line or tree as the topology that best fits user requirements. Besides, TTEthernet delivers scalable fault tolerance by allowing single-, dual-, and triple-redundancy for different levels of system integrity and criticality.
Scalable synchronization and implementation helps to decide on the most cost-effective solution:
- Software-based end systems for low-cost TTEthernet switch
- Dedicated TTEthernet controller and switch for highest performance (ASIC or FPGA-based)
Synchronization & determinism
TTEthernet solutions provide distributed, fault-tolerant, multi-master clock synchronization better than 1µs for guaranteed quality of service even in case of faults. IEEE 1588 synchronization will also be supported.
Compatibility
TTEthernet is compatible with Ethernet standards (IEEE 802.3) and available off-the-shelf components. In addition, it provides compatibility with IEEE 1588 and a variety of established real-time Ethernet standards. TTEthernet enables parallel traffic classes with different levels of quality of service.
Safety & availability
TTEthernet solutions maintain safety and redundancy at the network level without application involvement. Supporting functions at the network level ease application design and enable faster time to market. Replicated communication guarantees transmission of messages without any additional switch-over delays even if one channel or switch becomes faulty. This ensures higher availability and easier failure management.
Security
As synchronization, partitioning and real-time operation are secure against malicious access, TTEthernet supports safe operation in critical networks.
