1588V2 Packet Transmission via Payload Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of 1588V2 packet transmission in WAN interfaces is high due to the need for slicing and reassembling packets using an assisting module, which complicates the process.
Innovation Solution
The method involves inserting 1588V2 packets into the payload area of a data frame instead of the overhead segment, allowing the receiving end to perform time synchronization adjustments without the need for slicing and reassembling, thereby reducing complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If 1588V2 packet is inserted into OH overhead segment for transmission, then packet transmission can be achieved, but device complexity increases due to need for slicing and reassembling
Solution Approach 1:
The patent extracts the 1588V2 packet from the OH overhead segment and places it directly into the payload area of the data frame. This eliminates the need for slicing and reassembling operations, reducing device complexity while maintaining reliable packet transmission between IP and SDH networks.
2Reliability
If assisting module is used to slice and reassemble 1588V2 packet, then packet transmission is enabled, but transmission time increases
Solution Approach 1:
By extracting the 1588V2 packet from the OH overhead segment and placing it directly into the payload area, the patent eliminates the time-consuming slicing and reassembling operations performed by the assisting module, thereby reducing transmission time while ensuring reliable packet delivery.
3Device complexity
If 1588V2 packet is placed in payload area instead of overhead segment, then complexity is reduced, but packet transmission reliability may be affected
Solution Approach 1:
The patent extracts the 1588V2 packet from the OH overhead segment and places it in the payload area, simplifying the transmission process. The reliability is maintained through proper data frame structure and transmission protocols that ensure accurate delivery of the packet contents regardless of its location within the frame.
