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.
