This technology is titled as HANMOC (High-Accuracy Network Monitoring and Control) and employs the Segment Routing (SR) function, whose use as a next-generation forwarding technology has been in progress; it aims at the usage in the enhancement of the maintenance operation necessary for the 5G age and its quality assurance, in determining the routes for telecommunication service, etc. This technology aims at the usage in the enhancement of the maintenance operation necessary for the 5G age and its quality assurance
In new telecommunication services in coming years such as e-sports, Cloud gaming, and connected cars, an index called jitter that represents communication delays and the jitters in delays is going to be important, too, in addition to the conventional quality monitoring such as the quantity of data communication and packet losses.
As the existing means for monitoring delays, there are measurements with ping*1 and the ones that employ the function called TWAMP (Two-way Active Measurement Protocol) defined in RFC*2 4347 for network devices; however, as any of these monitoring means involves the behaviors made by software processing, monitoring with high accuracy used to be difficult because of the changes under influence of the load in software processing.
In this technology, the packets for the monitoring used for measurement are all embodied in hardware processing and the monitoring is performed in high accuracy to the unit at the level of µ second; thus, it aims at the usage of monitoring results in the network operation, in determining the routes of telecommunications, and so forth.
