SERDES Path Handshake Verification for Stable Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing SERDES technologies face instability issues due to unpredictable external conditions, leading to unreliable data transmission, as there is no effective solution to guarantee the stability of the SERDES path and ensure reliable data communication.
Innovation Solution
A transmission checking method involving three synchronization frames with identification tags is implemented, where a SERDES transmitter and receiver exchange synchronization frames to determine the normal state of their respective paths, ensuring stable data transmission through handshaking processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If SERDES is used for high-speed serial communication, then communication speed and integration are improved, but stability and reliability deteriorate due to sensitivity to external conditions
Solution Approach 1:
The patent applies preliminary action by performing a three-frame handshake verification process before actual data transmission. The transmitter sends a first synchronization frame, the receiver responds with a second synchronization frame, and the transmitter sends a third synchronization frame to confirm bidirectional path normality. This pre-verification ensures both transmitting and receiving paths are stable before communication begins, addressing the reliability issue while maintaining high-speed capability.
2Device complexity
If no transmission checking mechanism is implemented, then device complexity is reduced, but transmission reliability deteriorates
Solution Approach 1:
The patent applies segmentation by dividing the transmission verification process into three distinct synchronization frames with specific functions. Each frame contains identification tags (first and second identification tags) that segment the verification tasks: the first frame initiates verification, the second frame confirms receiver functionality, and the third frame confirms transmitter functionality. This segmented approach provides comprehensive reliability checking while maintaining clear protocol structure.
3Reliability
If bidirectional path verification is performed, then transmission security is improved, but communication time increases
Solution Approach 1:
The patent applies periodic action by implementing a structured three-frame periodic handshake sequence. Rather than continuous verification, the system performs a concise periodic check consisting of three specifically timed synchronization frames exchanged before data transmission. This periodic approach provides necessary verification while minimizing time loss compared to continuous monitoring schemes.

AI summary
Disclosed in the embodiments of the disclosure are a transmission checking method, node, system and computer storage medium. The method comprises: transmitting, by a SERializer/DESerializer (SERDES) transmitter, a first synchronization frame to a SERDES receiver; after the SERDES receiver receives the first synchronization frame, transmitting a second synchronization frame to the SERDES transmitter; and after the SERDES transmitter receives the second synchronization frame, transmitting a third synchronization frame to the SERDES receiver, such that the SERDES transmitter and the SERDES receiver can determine that a transmitting path and a receiving path of the SERDES transmitter and the SERDES receiver are in a normal state respectively.
