Where do attemps to develop a proposal for a Reliable
Datagram Protocal for Internet stand? Have there been
any attemps to implement RDP/IP for 4.2? If
anyone has something they need tested (even if it involves
our man power) we would really like to hear about it.
Can the Internet proposals be had? Who should know?
Jon Postel or someone at BBN?
We need such a service for a project we are working on.
It is the distribution of system calls (remote file access
and process execution), is done in the kernel and already
does open,creat,read,write,lseek. We are using UDP for the
moment, but the inter-kernel communcations expects the network
to be reliable. This is a port of the NETIX system from Bell
Telepone Manufacturing, Antwerp, Belgium. BTM already has
NETIX for V7, SIII, and IS/3.
NETIX is a trademark of Bell Telephone Manufacturing, Antwerp, Belgium.

From: Bob Walsh <walsh@BBN-LABS-B.ARPA> There is an RFC out for the Reliable Datagram Protocol (RDP), and the RFC may be obtained from the Network Information Center at SRI. I've had an implementation for the VAX (4.2BSD) running since July 4th. We're still performing experiments with it to measure throughput and machine loading, but so far it compares very favourably with TCP. bob walsh ARPA: walsh@bbn-labs-b UUCP: decvax!genrad!wjh12!hscvax!walsh

Bob Walsh of BBN Labs has just implemented RDP for 4.2BSD.
Details on distribution, etc., aren't firm yet, though interested parties
should probably drop him a line. His address is bbncca!walsh.

I looked at RDP (RFC908) hoping it was the long awaited reliable datagram protocol, but alas it's something different. This RDP seems aimed at downloading programs, although it is also well suited to transferring digitized images over a network. It has less overhead than TCP, but far more than a datagram protocol. In particular, connection setup/teardown seem to be necessary for RDP.
