Hi Greg,

Sure, I did not say that.
The same, anyone can create and implement an ISD whatever.
I do not think the ISD solution should be standardized.

Best,
Tianran

Hi Tianran,
I agree that we can learn from an implementor's experience. But I don't think a solution must be standardized only because it is implemented.

Regards,
Greg

Looking at Zafar’s reply, I do not feel any uncomfortable.
Kireeti claimed hardware cannot do something. Zafar just showed an implementation example to justify.
I my opinion, the implementation practice should be encouraged.

The draft has been implemented for the exact (SLID) use-case on hardware platforms based on Broadcom Jericho2 family of ASIC
Please take a look at https://datatracker.ietf.org/doc/html/draft-decraene-mpls-slid-encoded-entropy-label-id-04#section-7
No such issue was noted


And Jericho2 is the only thing that counts in the entire world?
