RELY-RB

Time-Aware Redbox Switch

Critical systems require time-aware, high-availability networks. In addition, the complexity of modern network infrastructures in these venues overcomes the traditional concept of a "network management" appliance.RELY-RB is a new concept in intelligent appliances that integrates field-proven advanced technologies for packetless redundant Ethernet, sub-microsecond synchronization and network security. The device is capable of merging an entire LAN with a redundant network to interconnect PRP and HSR networks and extend HSR rings via QuadBox operation.

Keeping up with the times and innovating - Explore more potentials of TSN with Hongke

Time Sensitive Networking (TSN) is a new generation of network technology based on the evolution of the standard Ethernet architecture. It takes traditional Ethernet as the network foundation and provides a data link layer protocol specification for deterministic data transmission capability through mechanisms such as clock synchronization, data scheduling, and network configuration. Compared with traditional Ethernet, TSN can provide microsecond-level deterministic services, reduce the complexity of the entire communication network, and realize the convergence of information technology (IT) and operation technology (OT). With its precise clock synchronization, deterministic traffic scheduling, and intelligent and open operation and maintenance management framework, TSN can ensure the high-quality transmission of multiple business traffic in a common network, and it has both performance and cost advantages, and it is the development trend of the future network. This is the future trend of network development.

Currently, TSN technology has a high level of discussion in the automotive, industrial, rail transportation, and aerospace fields. As a non-vendor-bound real-time communication protocol, we believe that TSN technology has a good application prospect.

Welcome to contact us to explore and learn the integration of TSN technology with various industries, and actively promote more applications on the ground to jointly build a new world of intelligent interconnection.
