Exclusion: The receiving end uses an exclusion mechanism to eliminate duplicate data after receiving multiple copies. This can be achieved by comparing the received copies, selecting the unique data, and providing it to the upper level application.
Through replication and exclusion, the FRER mechanism effectively prevents data incompleteness caused by communication link failures or packet loss. Even if a packet is lost on one path, replication on other paths can still ensure the integrity and availability of the data.
The core goal of the FRER mechanism is to improve the reliability of the entire network. When facing uncertainty factors and network failures, this mechanism ensures redundant transmission and recovery of data. This is very important for application scenarios that require extremely high communication quality and data integrity, such as industrial automation and real-time control systems.
Fault detection and recovery mechanism
Fault detection and recovery mechanisms are important components in ensuring reliable communication in deterministic networks. Intended to improve network reliability through real-time monitoring and automatic recovery.
Real time fault detection:
By monitoring the status of nodes and links in the network in real-time, deterministic networks can detect faults in a timely manner and take corresponding measures. This fault detection mechanism allows the network to quickly detect node failures or link interruptions that may cause communication problems. Timely fault detection is the first step in improving network reliability, which helps prevent serious impacts of faults on communication.
Quick response to faults:
Real time fault detection helps network systems respond quickly to fault conditions. Once a fault is detected, the system can take immediate measures, such as switching to a backup path or backup node, to minimize the impact of the fault on real-time communication. This fast response mechanism ensures that the network can adapt and respond to fault events in the shortest possible time, improving the stability of the entire system.
