[comp.protocols.iso] XTP Protocol for FDDI?

toppin@melpar.UUCP (Doug Toppin) (07/12/90)

I am beginning to hear something about a protocol
called 'XTP' in relation to FDDI. Does anyone
know if this is available or still being worked,
and if so where? I know zero about it and am interested
in knowing if it is:
	* similar in services to TCP
	* datagram or connection oriented
	* what does getting X windows to know about it involve

thanks

XTP 3.4 protocol spec is available to anyone who wants it
by sending the request to xtp-relay@pei.com You should provide
your postal address.

Tapes of the protocol implementations in Sun and SGI versions are 
available to members of the Technical Advisory Board. TAB is a
consortium of about 20 companies, universities and government bodies
which are interested in the development of XTP. For more information 
send your queries to xtp-relay@pei.com

Most of the TCP/IP services are provided as well as others, e.g.,
an acknowledged sequenced-stream multicast.

>	* datagram or connection oriented

both are supported.

>	* what does getting X windows to know about it involve

Both client and server systems must support the XTP protocol family, i.e.,
the XTP protocol support must be in the kernel. Given that, the changes to
the client and server code are very minimal.
