Hi All,
The question was asked ....
"What system besides rose allows one to connect from east to west with
such a simple connect string besides tcp/ip???
Conditional answers. Conditional because Flexdigi is too new to VK for
networks to be established, and the TCP network which also carried Netrom
is in disarray because of changes to the telecommunications act which
caused many long established gateways (wormholes) to shut down.
Netrom (X1J) Connect command even simpler than Rose .... C <ALIAS>
Flexdigi from Flexnet. Connect sequence similar to Rose.
Connect sequence C <callsign> <input_digi> <output_digi> instead of ...
C <callsign> <input_digi> <output_Rose_number>
Of course, all protocols require that a 'decent' network exist or our traffic
goes nowhere.
Rose has been around for quite a while now and arguably its biggest failing
is the requirement to manually set up, or more correctly, failure
by node managers to maintain, accurate routing tables; this is where
the Rose protocol falls down the most, in my opinion.
Probably the the most valid complaints about Netrom (X1J) are the
overheads on each packet which keep a useable maximum paclen at 236 (Netrom
requires the other 20 to make 256) and wasted bandwidth with
nodes broadcasts. The other side of the coin for Netrom (X1J) is that the
routing tables are updated automatically, thus providing a reasonably
accurate indication of reachable nodes ... well it would if stations didn't
broadcast every node they know about, reachable or not!
Flexdigi, according to European reports, works very well with short turn
around times over hundreds of kilometres. Would it work any better under
local conditions than any other protocol? Probably not because we don't have
a backbone of dedicated high speed links like in Europe. Given the high speed
link network which exists in much (most?) of Europe, most protocols
would likely perform well.
As for AAPRA. The is no doubt that many networks across this country are a
direct reult of their involvement. AAPRA has provided much equipment to
ensure that a network was established and they are to be applauded for their
contribution.
Having said that, I believe AAPRA could make an even bigger contribution by
actively supporting the establishment of other protocols, if that's what the
amateurs of a particular area want. With Linux nodes on the increase (and
they can handle Rose, Netrom, TCP/IP and AX25, all in the one switch) there
exists the opportunity to maintain existing networks while fully supporting
other protocols and even splinter networks of other protocols. Again, this is
only my opinion.
In defence of AAPRA, they can't be held responsible for node managers or
clubs who fail to maintain the local node, sometimes at the expense of
network integrity. Maybe Harry has a point though about "out of service"
AAPRA supplied equipment being recalled if a node isn't
maintained or returned to service in a reasonable time ... and I'm not
going to define reasonable. Afterall, if these people obtain equipment with
the intention of providing a service, should there not be some
"contractual" requirement to maintain that service, particularly if it
is vital to network existance?
Maybe some of the established clubs have gone stale, maybe they or their
node manager no longer cares (in some cases). Some would argue that so few
members use packet so what's the point. The point is that we need reliable
nodes with good inter-node links to maintain users' interest and to encourage
newcomers to the mode. Remember all the hype about packet in the early 80's;
about how you could connect to any other station, anywhere on the network
with lightning speed and have keyboard chats in real-time ... ha! User
numbers grew, the nodes and networks didn't keep u with the pace, and users
dropped off because they knew they'd get the pension sooner than ***
connected to ...
What's already happening is that individuals and small groups are, as Karl
2DYX pointed out, privately funding installations in an attempt to bring
packet into the early 1990's ... sarcasm intended. I predict we'll see
even more small groups spring up over the next year or so and I further
predict that the protocol of choice will be TCP/IP (with Netrom) or Flexdigi.
Cheers ... Ray
