eCPRI Protocol Analysis

Key Features

• Monitor and decode eCPRI traffic to identify packet impairments, such as Missed Packets, Out of Order Packets, Duplicate Packets, and One-Way Delay
• Provides the message statistics for Sequence Analysis, One-Way Delay Measurement, Event Indication, Remote Reset, and Remote Memory Access
• Supports eCPRI analysis for each IPv4 and IPv6 pair address
• The All Links statistics enable sequence analysis for all available eCPRI links
• Supports One-Way Delay calculation in microseconds
• Supports identification of hardware faults, software faults, or vendor-specific faults for a selected Element ID
• Provides graphical representation of Remote reset statistics
• Supports Remote Memory Access statistics for each Element ID and also total statistics for all the elements

Protocol Stack

eCPRI Protocol Stack

GL’s eCPRI Analysis application provides the following message statistics.

• Sequence Analysis
• One-Way Delay Measurement
• Event Indication
• Remote Reset
• Remote Memory Access

One-Way delay measurement is used to estimate the delay between two eCPRI nodes. The One-Way Delay window displays the number of delay attempts, the average delay, and the minimum and maximum delay in microseconds. The delay values are plotted on a Point graph, which calculates the values at different intervals. The same values are also added to a table for each link.

Faults

The Faults tab displays the total number of faults, as well as the number of raises and ceases. Additionally, the tab shows these statistics for each element represented by the Element ID in a tabular column. The Faults tab also displays any hardware, software, or vendor-specific faults for the selected Element ID.

Notifications

The Notification tab shows the total number of notifications, as well as notifications for each Element ID displayed in a tabular column.

In addition, the Notification tab displays User Plane Data issues for the selected Element ID, such as Data arriving too late, Data Buffer Overflow, Data Buffer Underflow, and Data arriving too early.

Remote Reset is a feature used to reset one eCPRI node from another. An eREC can trigger a Remote Reset request to reset an eRE.

The Remote Reset feature displays statistics for each Reset ID, including the total number of successful and failed resets, as well as the total number of resets with successful and failed outcomes. The statistics are shown both in a PIE graph and in a tabular column.

Remote Memory Access allows the user to read from or write to a specific memory address on another eCPRI node. Any interface node, whether it's an eRE or eREC, can use this feature by sending a Read or Write Request. Then, the node waits for a Response to confirm that the operation was successful.

The Remote Memory Access feature displays statistics for each Element ID, as well as the total number of successful and failed read and write operations. The statistics include the total Read Count, Read Success, Read Failure, Write Count, Write Success, and Write Failure for each Element ID, as well as the total statistics for all the elements.
