排除:接收端在收到多個副本后,使用排除機制來消除重復的數(shù)據。這可以通過比較接收到的各個副本,選擇一份數(shù)據,并將其提供給上層應用。
通過復制和排除的方式,F(xiàn)RER機制有效地防止了由于通信鏈路故障或數(shù)據包丟失而導致的數(shù)據不完整性。即使某個路徑上的數(shù)據包丟失,其他路徑上的復制仍能保證數(shù)據的完整性和可用性。
FRER機制的核心目標是提高整個網絡的可靠性。在面對不確定性因素和網絡故障時,這種機制確保了數(shù)據的冗余傳輸和恢復。這對于對通信質量和數(shù)據完整性有極高要求的應用場景非常重要,如工業(yè)自動化和實時控制系統(tǒng)。
故障檢測和恢復機制
故障檢測和恢復機制是確定性網絡中保障可靠通信的重要組成部分。旨在通過實時監(jiān)測和自動恢復來提高網絡的可靠性。
實時故障檢測:
通過實時監(jiān)測網絡中的節(jié)點和鏈路狀態(tài),確定性網絡能夠及時檢測故障并采取相應的措施。這種故障檢測機制允許網絡迅速察覺到可能導致通信問題的節(jié)點故障或鏈路中斷。及時的故障檢測是提高網絡可靠性的一步,有助于防止故障對通信造成嚴重影響。
快速響應故障:
實時故障檢測有助于網絡系統(tǒng)快速響應故障狀況。一旦檢測到故障,系統(tǒng)可以立即采取措施,如切換到備用路徑或備用節(jié)點,以小化故障對實時通信的影響。這種快速的響應機制確保了網絡能夠在短時間內適應和應對故障事件,提高了整個系統(tǒng)的穩(wěn)定性。

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.
