1G MRS – 網管冗余交換機IP核

Product Overview

網管冗余交換機IP核(MRS)是SoC-e HSR-PRP交換機(HPS)和網管以太網交換機(MES)IP核的組合,具有冗余的以太網交換功能。MES模塊是一個無阻塞交叉開關矩陣,允許在所有端口之間進行連續傳輸。它實施存儲與轉發的交換方法,以完全滿足以太網標準策略關於轉發每個幀之前校驗幀的完整性。另一方面,HPS模塊在所需的端口中引入了HSR和PRP冗余功能。因此,MES和HPS的組合提供了最高的性能和與標準的最大兼容性。

    如何將CPU發起的流量發送到特定端口

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.
