In part one of this blog, we discussed the ways the Radio Access Network (RAN) is dramatically changing with the introduction of 5G networks and the growing importance of network visibility for mobile network operators. In part two of this blog, we’ll delve into resource monitoring and Open RAN monitoring, and further explain how Marvell’s Prestera® switches equipped with TrackIQ visibility tools can ensure the smooth operation of the network for operators.
Resource monitoring
The peak rate, which is close to 100%, can easily lead to egress queue congestion, resulting in buffer buildup and higher latencies.
图 1:
Note that slow monitoring techniques would not have detected the correct peak rate and would have created the false impression that peak rate is much lower.
图 2:
The vast amount of data points (continuous measurement of rates in the entire network) is dramatically reduced, allowing continuous monitoring of the entire network and providing extremely valuable information.

Open RAN Monitoring
As shown in Figure 4, such Cloud RAN solutions are expected to be deployed in Edge Data Centers, in proximity to the cell towers.
