In this generality, this is not true at all. You're confusing handshakes with protocol layering. You can do the latter without the former. For example, DNS uses UDP without introducing additional round trips because there is no explicit handshake. Lack of handshake generally makes error recovery quite complex once there are multiple protocol versions you need to support, but handshaking is *not* a consequence of layering. -- Florian Weimer <[email protected]> BFK edv-consulting GmbH http://www.bfk.de/ Kriegsstraße 100 tel: +49-721-96201-1 D-76133 Karlsruhe fax: +49-721-96201-99 --------------------------------------------------------------------- The Cryptography Mailing List Unsubscribe by sending "unsubscribe cryptography" to [email protected]
