-------------------------
First NOTE that this is a BETA version, the first REAL NOT BETA -
Release will be 3.30!
Also notice that there are some extra changes in ZyRion, that are NOT
Documented yet.
We decided to release this version so soon as it was ready for the -
public, Since there are so many ZyRion Versions, and to keep the Sysop
Version and Beta Version compatible with the user Version, we released
this one!
In compare with ZMODEM, ZYRION uses another way to send his packets also
the CRC method has been taken out of the loop, since DFC was a better -
method to support the Bit Matrix Shift BMS[HI] and BMS[LO] sequences.
Matrix Lock at X
-----------------
MLock has been added, if you SET the MLOCK environment you can change the
ZyRion BMS[HI] and BMS[LO] Switch frames, IF you set "SET MLOCK=4" then -
ZyRion will try to send the first 4 subpackets in FAST High mode instead
of LOW & HI Mode.
This will give a fast start, 20480 bytes in 8 seconds at 14400 baud.
Set MLOCK to 8 will give 40516 bytes in less then 18 seconds at the same
speed, however IF you set this to high, ZyRion will lockup.
MLOCK has one purpose, and that is to get the first X subpackets out so
fast as your Modem can handle it, a Safe margin would be 2!
Some tests of ZYRION protocol error recovery performance have been
made. A PC-AT with SCO SYS V Xenix or DOS 6.0 was connected to a PC
with DOS 3.1 either directly at 9600 bps or with unbuffered dial-up
1200 bps modems. The ZYRION software was configured to use 2048
byte data subpacket lengths above 2400 bps, 1024 otherwise.
Because no time delays are necessary in normal file transfers, per
file negotiations are much faster than with ZMODEM, the only
observed delay being the time required by the program(s) to update
matrix coded buffers.
During a file transfer, a short line hit seen by the receiver
usually induces a DFC error. The interrupt sequence is usually seen
by the sender before the next data subpacket is completely sent, and
the resultant loss of data throughput averages about half a data
subpacket per line hit. At 1200 bps this is would be about .75
second lost per hit. At 10-5 error rate, this would degrade
throughput by about 9 per cent.
The throughput degradation increases with increasing channel delay,
as more data subpackets in transit through the channel are discarded
when an error is detected.
A longer noise burst that affects both the receiver and the sender's
reception of the interrupt sequence usually causes the sender to
remain silent until the receiver times out in 6 seconds. If the
round trip channel delay exceeds the receiver's 6 second timeout,
recovery from this type of error may become difficult.
Noise affecting only the sender is usually ignored, with one common
exception.
In summation, ZYRION performance in the presence of errors resembles
that of ZMODEM or TMODEM, ZMAX e.c Short bursts cause minimal data
retransmission.
Long bursts (such as pulse dialing noises) often require a timeout error
to restore the flow of data.
Unlike traditional and many recently introduced protocols, ZYRION
Signature Pulse safeguards all data and supervisory information with
effective error detection.
ZYRION rapidly transfers files, particularly with buffered (error
correcting) modems, timesharing systems, satellite relays, and wide area
packet switched networks.
User Friendliness is an important ZYRION feature. ZYRION AutoDownload
(Automatic file Download initiated without user intervention) greatly
simplifies file transfers compared to the traditional protocols.
ZMODEM also has this feature (it was the first one), and ZYRION folows
this step.
ZYRION provides advanced file management features including Crash
Recovery, flexible control of selective file transfers, and security
USER "coded in the key" verified sequence.
ZYRION protocol features allow implementation on a wide variety of systems
operating in a wide variety of environments. A choice of buffering and
windowing modes allows ZYRION to operate on systems that cannot support
other streaming protocols. Finely tuned control character escaping allows
operation with real world networks without Kermit's high overhead.
ZYRION and ZMODEM are the only high performance high reliability public
protocols that does not require large buffer allocations for normal file
transfers.
This feature makes ZYRION one of the best protocols on the marked today.
