[bit.listserv.policy-l] A new LISTSERV

ROBINSON@BITNIC.BITNET (Andrew T. Robinson) (02/12/90)

My primary gripe with the current LISTSERV concept is that it requires
"smart" file distribution--routing over routing.  You have a topology
of LISTSERVs which is constrained by the topology of the real network.

If the LISTSERV "network" could better approximate the real topology of
the network (meaning it would have to run on other than IBM VM systems),
the "smart routing" could be eliminated and each node's routing tables
could be used instead.  Unfortunately, the only way to a non-VM
implementation of LISTSERV is by a line-by-line analysis of the code.

Andy:  *all* network services are constrained by the topology of the real
network.  You can't send bits over a non-existent link.

If enough people were running RSCS V2.2+ or 2.3, you could use the
built in list processor feature.  Then, all LISTSERV-like software would
have to do is send out a single copy of the file with a distribution
list, and RSCS, the guy who already KNOWS the topology of the network,
would send the minimum number of files.  Voila, no more duplication of
topology information.  This is how things work in VNET, and we do quite
a bit of mailing list traffic here, too.  Does JNET support this
feature?  All you really need is the ability to handle multiple dataset
headers, which is how MVS manages to be compatible, even though it
cannot process the initial distribution list.  Note also, that the
initial list processor doesn't even have to be on the same machine as
the mailing list generator, it can send it to a different node for list
processing.
