Hi,
I need to "quantify" the performance of three different network synchronization algorithms I've implemented:
- PTP (& -ish)
- PTP (& -ish) without special MAC
- a proprietary implementation
I figure I can use a degenerate network configuration to give me absolute "best case" values (two devices w/ XOVER cable and careful control over the activities in each node).
I can also come up with some numbers for "typical" performance as well as quantifying that traffic.
The problem is figuring out what "worst case" values I'll see in a deployed configuration (i.e., where I have little or no control over the other network devices). To be more specific, how to inject traffic onto the wire with deliberate intent to degrade my control (short of the pedantic case of effectively "shorting" cables for indefinite periods of time)
Do they make boxes that deliberately do this (i.e., precise control over the sizes and content of packets as well as precisely *WHEN* they are placed on the wire)? Some pointers to products -- or suitable search terms -- would be appreciated!
Thanks!
