Dear Working Group,

I would like to request a short timeslot to present a use case and explore how the pending draft, An Unreliable Oblivious HTTP Extension (https://datatracker.ietf.org/doc/draft-wood-ohai-unreliable-ohttp/), can enhance privacy protection for our use case.

We have been working on implementing the Distributed Aggregation Protocol for Privacy Preserving Measurement (https://datatracker.ietf.org/doc/draft-ietf-ppm-dap/). As part of our implementation, we have adopted the OHTTP protocol to improve the user's privacy by employing it on our data upload path. We believe the unreliable OHTTP extension draft can further benefit our implementation, by allowing the Relay to batch and reshuffle the requests. This mitigates potential timing attacks by decoupling the target resource from the client requests' timing and order.

Thank you for your consideration, we look forward to the possibility of contributing to the ongoing discussions.

Best Regards,

Linmao Song
