帶寬保障和流量控制
通過(guò)CBS（Credit-Based Shaper）等機(jī)制，確定性網(wǎng)絡(luò)技術(shù)提供對(duì)流量的有效控制，確保實(shí)時(shí)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(jī)制，通過(guò)分配信用額度給每個(gè)實(shí)時(shí)流，以確保它們?cè)谝?guī)定的時(shí)間窗口內(nèi)能夠獲得足夠的帶寬。這種機(jī)制允許實(shí)時(shí)流按照其特定的服務(wù)質(zhì)量需求進(jìn)行傳輸，避免了由于擁塞而導(dǎo)致的通信延遲和不確定性。
通過(guò)CBS等機(jī)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(jí)。這確保了實(shí)時(shí)流在網(wǎng)絡(luò)中的傳輸過(guò)程中不會(huì)受到非實(shí)時(shí)流的干擾，從而提高了實(shí)時(shí)通信的穩(wěn)定性和可靠性。
通過(guò)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(dǎo)致通信延遲的增加和數(shù)據(jù)包的丟失，對(duì)于實(shí)時(shí)應(yīng)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(yù)定的時(shí)序得以傳輸，從而降低了擁塞的風(fēng)險(xiǎn)。
數(shù)據(jù)包復(fù)制與排除
數(shù)據(jù)包復(fù)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(qiáng)機(jī)制，通過(guò)在多路徑上復(fù)制和排除數(shù)據(jù)幀的方式來(lái)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(jī)制，特別適用于面對(duì)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(duì)某些不可預(yù)測(cè)的問(wèn)題時(shí)，仍能保持通信的穩(wěn)定性。FRER機(jī)制采用了兩個(gè)主要步驟：復(fù)制（Replication）和排除（Elimination）。
復(fù)制：在數(shù)據(jù)包傳輸時(shí)，F(xiàn)RER機(jī)制通過(guò)多個(gè)路徑同時(shí)發(fā)送相同的數(shù)據(jù)幀，創(chuàng)建了幀的多個(gè)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.
