[WG chair hat: on]

Hi Jie,

That implementation experience was based on their implementation for the Tofino architecture, which has subsequently been discontinued by the manufacturer.
(https://www.intel.com/content/www/us/en/content-details/827577/intel-tofino-products-pcn-827577-00-product-discontinuance-tofino-end-of-life.html)

I’m unaware of any other publicly documented implementations, but more importantly the MPLS WG does not have an implementation requirement. As you know, MPLS is a highly competitive area and vendors are unlikely to disclose implementations before going public with them, and silicon lifecycles are typically quite long.

Regards,
Tony

As part of the WG LC, it would be important to check whether the issues raised at that time have be addressed by the latest version. It would be helpful if some feedback on the latest version can be provided by those implementors.
