Hot to set traffic class of IPv6 socket?

鲲鹏贺 1

I'm trying to modify the traffic class of the IPv6 socket just like the tos of IPv4. But it seems there is no IPv6_TCLASS like IP_TOS to use in the docs (ipproto-ipv6-socket-options)

The doc of IP_TOS mentions that it is recommended to use the QoS API. But I'm looking forward to using nearly the same code as on Linux, which uses IP_TOS/IPV6_TCLASS directly.

Hello,

Welcome to Microsoft Q&A!

According to the Doc: IPPROTO_IPV6 socket options

The IPV6_TCLASS socket option isn't available in Windows with IPPROTO_IPV6.

You could refer to the Github:https://github.com/microsoft/WSL/issues/1869

Thank you.

Oh, thanks for your answer.

I opened this question because I was trying to wrap the getter and setter of the traffic class. But, after reading the doc and your answer, I decided to focus on Unix-like OS and ignore windows for now.

I want to leave this open for some more straightforward way to modify a socket's traffic class. Maybe using the QoS API (Seems quite complicated compared to the getsockopt/setsockopt to me).
