Hello Ivo, May i ask how you are planning on separating ICMP? Although ICMP sits on top of IP, it is an IPv4 specific control procotol. What i think would be interesting would be to define a set of standard error messages to propagate down the stack so IP would reply with an ICMP error to the source. For instance, "Port unreachable" to be used by UDP. Hugo On 6/27/07, Ivo Vachkov <ivo@xxxxxxxxxxx> wrote:
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello all, I have somewhat more generic question. Since the BeOS networking stack is using 'top-down approach' is it possible to call routines from one layer in another. For example calling ICMP code in IP module. If so, I'd appreciate the guidance, and if not, I'd appreciate a proposal for reorganization. Thank you very much in advance. /ipv -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (FreeBSD) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFGglVnLI0ttz7vDJ0RAqp4AKCL0FZG4ohLV3M0bFznq1BZBXJ7wwCglKmZ Zu6W2eZY8GnHtbeUYCRKU2g= =C/wG -----END PGP SIGNATURE-----
