crossbow discuss - Aug 2006 - What protocolls?

It says on the information page for Crossbow that it suppors "any
protocol". This includes a protocol that I''ve developed myself as
well?

And can crossbow be easily ported for other type of NICs for example cards that
use signaling over SS7?

Yes. The choice of protocol is dependant on protocol field in IP header.
As long as you have a unique value there, it will work. BTW, the current
bit out in open Solaris only have support for TCP but we are adding
support for others as well.

Sure. You just need to make sure that the driver is based of GLDv3
which is already shipping. Formal documentation on how to write GLDv3
based driver will be out soon but if you want to start sooner, we
can help you out.

and just to avoid surprises,  today''s binary distro of CrossBow on 
OpenSolaris doesn''t have the fix
for 6453650 (VNICs should support any type of MAC, not just ethernet) yet.
Till then, the creation and use of a VNIC over a non ethernet MAC device 
may or may not work properly.

We''ll make sure to mention that fix in the announcement and the release
notes of the future snapshot
that includes it.

    Kais.

We''ll need to extend the netrcm(1x) syntax to support
"transport=number".
currently, it supports only "transport={TCP|UDP|SCTP} "


    Kais


P.S. netrcm is the CLI to manage the network policy resource controls, 
per protocol, per port, etc ...
netrcm is being worked on and will soon be included in the OpenSolaris 
CrossBow snapshot.

But if I have a signaling card that doesn''t support Tx/Rx rings, it can
be "emulated" with another abstraction layer (pseudo hardware layer)
if I understood correct? This would make a card that has no support what so
ever, and expects to have one address (IP/PC), to function properly with
virtualization?


Thanks for your answers.

You are correct. Once the emulation layer code comes in, even your
typical DLPI driver will be able to function properly.
