帶寬保障和流量控制
通過CBS（Credit-Based Shaper）等機制，確定性網(wǎng)絡(luò)技術(shù)提供對流量的有效控制，確保實時流得到帶寬保障。這有助于避免擁塞，提高網(wǎng)絡(luò)的可靠性。
CBS是一種流量控制機制，通過分配信用額度給每個實時流，以確保它們在規(guī)定的時間窗口內(nèi)能夠獲得足夠的帶寬。這種機制允許實時流按照其特定的服務(wù)質(zhì)量需求進行傳輸，避免了由于擁塞而導致的通信延遲和不確定性。
通過CBS等機制，確定性網(wǎng)絡(luò)技術(shù)能夠有效地控制流量的傳輸速率和優(yōu)先級。這確保了實時流在網(wǎng)絡(luò)中的傳輸過程中不會受到非實時流的干擾，從而提高了實時通信的穩(wěn)定性和可靠性。
通過有序的流量控制，確定性網(wǎng)絡(luò)可以有效地避免擁塞的發(fā)生。擁塞可能導致通信延遲的增加和數(shù)據(jù)包的丟失，對于實時應用而言，這是不可接受的。帶寬保障和流量控制確保了網(wǎng)絡(luò)中的數(shù)據(jù)流按照預定的時序得以傳輸，從而降低了擁塞的風險。
數(shù)據(jù)包復制與排除
數(shù)據(jù)包復制與排除（Frame Replication and Elimination for Reliability，F(xiàn)RER）是一種網(wǎng)絡(luò)可靠性增強機制，通過在多路徑上復制和排除數(shù)據(jù)幀的方式來防止數(shù)據(jù)包丟失。
FRER是一種用于提高網(wǎng)絡(luò)通信可靠性的機制，特別適用于面對通信鏈路故障或數(shù)據(jù)包丟失的情況。它旨在確保數(shù)據(jù)包能夠在網(wǎng)絡(luò)中可靠地傳輸，即使在面對某些不可預測的問題時，仍能保持通信的穩(wěn)定性。FRER機制采用了兩個主要步驟：復制（Replication）和排除（Elimination）。
復制：在數(shù)據(jù)包傳輸時，F(xiàn)RER機制通過多個路徑同時發(fā)送相同的數(shù)據(jù)幀，創(chuàng)建了幀的多個副本。這確保了即使其中一條路徑發(fā)生故障，其他路徑上的數(shù)據(jù)仍然可用。
Bandwidth guarantee and traffic control
Through mechanisms such as CBS (Credit Based Shaper), deterministic network technology provides effective control over traffic, ensuring real-time flow is bandwidth guaranteed. This helps to avoid congestion and improve network reliability.
CBS is a traffic control mechanism that allocates credit limits to each real-time stream to ensure that they can obtain sufficient bandwidth within a specified time window. This mechanism allows real-time flows to be transmitted according to their specific quality of service requirements, avoiding communication delays and uncertainties caused by congestion.
Through mechanisms such as CBS, deterministic network technology can effectively control the transmission rate and priority of traffic. This ensures that real-time streams are not disturbed by non real-time streams during transmission in the network, thereby improving the stability and reliability of real-time communication.
Through orderly flow control, deterministic networks can effectively avoid congestion. Congestion may lead to increased communication latency and packet loss, which is unacceptable for real-time applications. Bandwidth protection and traffic control ensure that data flows in the network are transmitted according to predetermined timing, thereby reducing the risk of congestion.
Packet replication and exclusion
Frame Copy and Elimination for Reliability (FRER) is a network reliability enhancement mechanism that prevents packet loss by replicating and excluding data frames on multiple paths.
FRER is a mechanism used to improve the reliability of network communication, particularly suitable for situations such as communication link failures or packet loss. It aims to ensure that data packets can be reliably transmitted in the network, maintaining communication stability even in the face of some unpredictable problems. The FRER mechanism adopts two main steps: replication and elimination.
Copy: During packet transmission, the FRER mechanism sends the same data frame through multiple paths simultaneously, creating multiple copies of the frame. This ensures that even if one path fails, data on the other paths remains available.
