Re: Adding a new OSI layer

Hi Josef,

But telnet/(t)ftp/[rs]sh are implemented in user land.
ISO/OSI Layer 5 is the Session Layer, not the Transport Layer!
Good point, I agree.

Only put into the kernel what must absolutely belong into the kernel! I
see no reason why the Session Layer should be implemented in kernel space.
But if you do not want to change existing applications (which use
interfaces like socket()...) then it would be necessary to change
something either in the kernel or in a system library.

So it depends on whether you have to consider migration or not...

Thanks
Christian
