APRICOT 2025: IP Measurements
At APRICOT 2025, Bart Van de Velde of Cisco Systems presented “IP Measurements.”
Customers detect the network problem then we troubleshoot. Operators repeatedly encounter this issue over time. Why legacy network performance monitoring solutions cannot detect the application experience?
The network fabric is built on top of IP. The nature of IP is ECMP (i.e., there are many ECMP Path between the edge nodes that connect our customers). Legacy network performance monitoring solutions cannot measure the customer experience due to the lack of scale to measure all ECMP Paths and relying on metric such as min/max/average which doesn’t reflect the experience of all customers.
In this talk we explain the various challenges to measure IP networks and explain the proposed solution to overcome these challenges.
