Table of Contentsatmtcp - set up ATM over TCP connections atmtcp -l [lclport]
atmtcp -c host [rmtport]
DESCRIPTIONatmtcp establishes TCP connections and configures them as virtual ATM devices. Such pairs of "ATM over TCP" devices are connected as if they were real ATM adapters linked by a cable or fiber, i.e. PDUs sent on a given VPI/VCI are received at the other end on the same VPI/VCI. The optional port arguments are used to run atmtcp on a different port than the default port (8401).
- -l
- listen for an incoming connection. Only one connection is accepted.
- -c host
- connect to an instance of atmtcp running on the specified host.
Only AAL PDUs are exchanged, no segmentation or reassembly is performed. That implies that using different AALs (e.g. AAL5 and AAL0) on either side will reveal limitations of this emulation. Classical IP can't be used over atmtcp connections. atmtcp doesn't detach from the TCP socket it creates, so it has to run during the whole lifetime of the connection. Forcibly terminating atmtcp may crash the system. Werner Almesberger, EPFL LRC <werner.almesberger@lrc.di.epfl.ch> atmdiag(8), clip(8), sonetdiag.8.html" >sonetdiag(8)
