			    PCBMRK and PCBCHK

     These routines are used to manage the transfer of PCB's to and from
Front End Kontrollers in a Multi-Cpu, or Cached environment.  The protocol
for using these two routines is as follows.

   PCBMRK	This routine should be called after the PCB is altered by
		the -10.  In a cached environment, it stores the Cache Sweep
		Serial number so that PCBCHK can tell if cache needs to be
		swept at a later date.  On a non-cached, or multi-cpu machine
		(free core is not cached on a SMP system) this routine is a
		no-op.

   PCBCHK	This routine should be called with J := FEK address, and
		U := PCB address.  It should be immediatly before either
		"FEKRDD" or "FEKWRT" is executed.  If it skips, then that
		implies that the FEK may access the data.  If it does not
		skip, then either the FEK is on the wrong CPU, or the data
		is still in cache, and may not be accessed by the FEK.

COMMENT	~

This novel is intended in guiding network managers who want to fine tune
their networks for performance. A word of caution before we start: The
parameters as currently defaulted, were what we had set during field
test. We know that in the majority of cases, these parameters work to
most DEC systems even though not with optimal performance. Modifying these
parameters can cause disaster, so understand what you are attempting
beforehand, and be conservative in modifying them. Be aware that DEC may
not agree with your settings, and will request them be set back to standard
values before debugging any problems in your network.

The critical timer in this case is the AVERAGE DELAY to a node. This is
kept by LLINKS by timestamping each data message it sends, and waiting
for the ACK to come back. When it has the ack, it has the delay for that
particular message, and it averages that delay into the average delay.

This delay time is used as a base in computing when to retransmit, and
when to decide that a link has gone sour, and as such is the single most
important timer as far as performance is concerned. Below is a description
of some parameters controlling how this delay is calculated.

%NSFLR - Changing this will probably only affect nodes which are relatively
	close to this node. The desirable effect of lowering this is to
	speed up recovery after a lost message, since the lost message will
	be re-trasmitted much sooner. The undesirable effect is that links
	will break if the delay changes much.

%NSRUF - Changing this will probably only affect problems involving congestion.
	Lowering this will decrease the effect that congestion has on a link,
	but will increase the number of messages sent, which can aggravate
	the congestion. If congestion gets too bad, not enough messages get
	through to keep the link alive, and it breaks.

%NSWGT - This affects how much a single delay will affect the average delay.
	Increasing this causes the delay to change more slowly, lowering it
	causes the delay to track reality more closely. Tremble before you
	change this one - Lowering it can cause positive feedback in your
	network with delay and retransmissions oscillating out of control,
	while increasing it can cause links to be unable to adapt to changing
	conditions.

%NSRTH - Retransmission threshold. This controls the number of times we
	re-send a message before giving up. Increasing this will give the
	other side a better chance of keeping your link alive, but can
	aggravate congestion problems.

%NSDLY - Delay factor. This multiplied by the average delay to a node is
	used as the retransmission  timer. Note that this factor is kept in
	1/16ths, so the default is 3 even though network management says
	48.

The main theme throughout this novel is congestion. If congestion did not
exist, we would recommend lowering %NSFLR and %NSWGT, and increasing %NSRTH.
The term congestion, as used in this novel, indicates the situation where
some node, possibly an intermediate, possibly a destination, does not have
buffers for all the messages that he is receiving, and must discard some.
The destination does not receive these messages, the source does not receive
an ack for them, so must eventually retransmit them.

The reasons congestion can occurr are numerous; Some of the more common ones
are:
1) A node with a high speed line and a low speed line; Messages are coming
   in the high speed line to be retransmitted on the low speed line faster
   than the low speed line can handle. The messages pile up, and eventually
   some of them are dropped.

2) A node with cross-traffic. Messages going from node A to node B through
   node C have no trouble, until messages from node D going to node E also
   through node C eat up buffers.

3) Many links to same node. Since flow control is managed on a per-link basis,
   there is nothing to keep many links from transmitting their limit all at
   the same time. If the source and destination are the same type of system,
   often this isn't a problem since they both have the same limit on the number
   of buffers. When they are of different type, and the source has more
   buffers available than the destination, the destination cannot process them
   all in time.

We cannot predict all situations in the field, but here are some suggested
scenarios, and suggestions as to ways of improving performance:

Scenario A: TOPS10 - DTE - DN20/MCB - DMR(56kb) - VAX
	Continual file transfer activity, spurts of NRT (terminal)
	activity. Occasional congestion loss caused by the spurts of
	NRT activity (reason 3).

	In this case, it could be possible to act as if congestion didn't
	exist, and lower %NSFLR, %NSWGT, and %NSDLY. Since congestion is
	fleeting, the retransmissions will occurr after the congestion
	has gone away (the user has stopped banging away at his terminal)
	and should not cause problems.

Scenario B: KL - DTE - DN20/MCB - DMR(56kb) - VAX
				\ KDP(9600) - RSX
	File transfer activity from KL to RSX and VAX. NRT activity, but
	irrelevant. High congestion loss to RSX due to low speed line from
	DN20 to RSX.

	In this case, congestion is the dominant theme. The DN20's buffer
	space is always going to be busy, since every time the RSX system
	sends data requests (credits, permissions) the KL will be able to
	fill the MCB before the MCB will have a chance to finish transmitting
	a single message. Depending on the number of buffers in the MCB,
	this will probably work fine until other network activity occurs.
	When other network activity occurrs (such as file transfer to the
	vax, or terminal activity), congestion loss will start up. In this
	case, since the actual delay of messages isn't increasing, you want
	to increase %NSWGT to avoid changing wildly every time a message is
	retransmitted. You also want to set %NSRUF to provide an upper limit
	on how high the delay can get. The danger here is setting it so low
	that congestion hasn't been relieved by the time we retransmit, or
	setting it so high that performance goes to zero.

Scenario C: TOPS10 - DTE - DN20/MCB - DMR(56kb) - DN20/MCB - TOPS20
	File transfer activity from TOPS10 to TOPS20. Performance varies
	wildly depending on load on TOPS20 system, including broken links
	if the load gets too high on the TOPS20 system.

	The dominant theme here is the fact that TOPS20 (5.1 and 6.0) will
	vary the delay for message response. If the load is light, and the
	job receiving messages is runnable, the turnaround will be fast. If
	the job gets blocked or pages out, the acks will not be forthcoming
	until the job unblocks and receives the messages, which can be a
	long time. We have observed cases where the delay to a TOPS20 system
	was less that 200 milliseconds, and suddenly a message didn't receive
	an ack for over 20 seconds - Apparantley the job was paged out, and
	there were other processes with higher priority running.

	In this case, the only thing you can do is to protect yourself against
	the delay changing drastically. We would suggest that you should limit
	yourself to attempting to keep the link open and not worry about speed.
	In this case, increase %NSFLR to something large, which will cause
	retransmissions to take a long time, but will allow the link to survive
	long periods with no activity. ALso increase %NSRTH, to increase even
	further the odds of living through a drought of messages.

These scenarios provide idealized situations. Customers are likely to have
a combination of the above situations, or something else entirely, and
possibly the above mentioned controls are not enough. A situation where a
customer needs different controls over different nodes might occur, for
example. The routine in LLINKS is UPDELAY, and the location of interest
to anyone wanting to patch this is UPDLY1, where we have in T1 the new delay
to the node. At this point we are about to range check against NSPFLR and
NSPRUF, and then store it away. If you are attempting to insert some extra
site-dependant knowledge into this algorithm, this would be the place to
do it.

There are two tools supplied which should help you understand what is
happening in your network - DNSNUP/DNTATL and DCNSPY. DNSNUP will write out
to disk EVERY message that passes through ROUTER. This output can be later
be converted to readable form with DNTATL, so you can analyze where messages
got lost and possibly why. DCNSPY is a DPY tool which allows you to watch
links in real time. The fields displayed are defined in D36PAR, where the
convention is: Five character name, first two characters are the name of
the structure, last three characters are the name of the field. The structure
is found as "BEGSTR xx", and the field within is found as either "WORD xxx"
or "FIELD xxx", depending on its size.

There are a limited number of comments/detailed descriptions for the fields
available within DCNSPY with the COMMENT switch. Since these descriptions
are at least two years old, it may be possible to find a more up-to-date
or complete description in D36PAR itself.
