This seems to be an instance of this problem:

but I haven't tracked it exactly yet-- am working on it.

I think that supporting both attributes has the problem that the user can break
the synchronization between the values by changing only one default value with
Config::SetDefault or from the command line.
To avoid this problem, my proposal is to support the Frequency attribute, which
is more user-friendly, and drop the Lambda attribute.

This has been around for over a month, and I've been poking at it while I get
time-- the fix has not been obvious. I will keep at it.

I believe that order of attribute initialization is not guaranteed. I would
opt for Nicola's suggestion as well.

--- Comment #1 from Tom Henderson 2012-05-04 16:55:53 EDT ---
The problem here is that the combination of the position allocator and mobility
model configuration does not permit arbitrarily large numbers of wifi stations.
mobility.SetPositionAllocator ("ns3::GridPositionAllocator",
"MinX", DoubleValue (0.0),
"MinY", DoubleValue (0.0),
"DeltaX", DoubleValue (5.0),
"DeltaY", DoubleValue (10.0),
"GridWidth", UintegerValue (3),
"LayoutType", StringValue ("RowFirst"));
mobility.SetMobilityModel ("ns3::RandomWalk2dMobilityModel",
"Bounds", RectangleValue (Rectangle (-50, 50, -50,
50)));
This starts to segfault at --nWifi > 18 when the initial layout of nodes goes
beyond the bounding box.
Will fix in a minimal way that doesn't require too much touching of the
tutorial text; specifically, to enforce that --nWifi <= 18.

I'm neutral with this change. Meaning the pros and cons are balanced.
Pros: you're right, it's a nice piece of code and *could* be useful.
Cons: the original algorithm was proposed for TCP and (to my best knowledge) is
not used in any other protocol.
If you can provide a practical example of where it could be reused, I'm more
than keen to give a +1

Subject: [Ns-bugs] [Bug 1413] Proposed modification and extensions of
TopologyRead module
In-Reply-To: 2012-05-06 09:55:32 EDT ---
Hi,
I have a general comment about the patches: I can't figure out exactly what is
the intended purpose. I'm not against changes, but I am a bit concerned when
the changes are not meant to address a specific case.
Now, the changes you're proposing are not "bad", but it's not clear to me where
the code will be reused. The Link class was meant to be an internal
implementation for the TopologyRead modules, thus is private. As an internal
implementation class, everything is done so to a future TopologyRead
implementation change can't affect any other code.
Now, if your changes are so to extend the TopologyRead module itself, the Link
class can be left private. If, on the other hand, the changes are so to use the
Link class in a completely different module, then the right approach is to
design *from scratch* a new class to be put (for example) in the network/utils
directory, and have both modules relying on it. The whole point of modules is
to avoid changes in one module breaking other modules (as much as possible).
Those are, basically, my concerns. I think we can find a suitable way to fix
this point.
T.

I would support moving it to network/utils/ just based on Alex's stated need.

There is a small copy/paste error in the IPv6 version of doxygen (referencing

I'm recommending (from the code review comments) to:
- delete TestMap2 test attribute (unused and not understood)
- keep bug 1352 open for handling strings and also for resolving the question
on attribute tests in the code review
- otherwise merge the latest patch so LENA merge can proceed

Those were supposed to have been removed from the ns-3.13 release with this
changeset, due to a GPLv2 license incompatiblity:
http://code.nsnam.org/ns-3.13/rev/e6eee72c544b
However, perhaps I did not remember to "hg forget" the files and they crept
back in.
In any case, this license issue is resolved and the files will be part of
ns-3.14.

As a final comment, work pending to be done:
- String support
- Test getter and setter for vector and maps
I am sorry but was not able to work on this lately. I will try my best for the
next release.

I can't reach the accessor "PacketDrop" from my NS3 code patched in attachment
1015 in comment 3. I try something like this:
Config::Connect("/WifiMacQueue/PacketDrop",
MakeCallback(&DequeueFirstAvailable));
What is the correct way of reaching this callback function for different sender
nodes / access categories?

It's been a very long while since I've touched NS3 code. I recall I've always
just attached the traces the long way - first get a Ptr, then
call the TraceConnectWithoutContext function.
I can't remember using Config::Connect. In any case, this TraceSource will tell
you when a specific MAC queue drops a packet (not when any que drops a packet).
Therefore you actually need to connect to a specific WifiMacQueue (ie. the
queue that is attached to a specific MAC of a specific Node).
Unfortunately I can't give any more help than this other than referring you to
http://www.nsnam.org/docs/release/3.13/manual/singlehtml/index.html#overview

I solved the pybindgen generation error. However, when building the python
bindings another bug occurs. Pybindgen does not support containers whose
elements are of a type that has no default constructor. I need to commit this
patch to make the python bindings build again.
But I do not know who is the DSR maintainer. He needs to approve this patch.
Tom, do you know who he is?

I don't get this error. Maybe the recent upgrade to pybindgen trunk revno 809
solved it. Do reopen if the problem persists.

You're looking at the doxygen of ns-3-dev, in fact the file is present in
ns-3-dev:
http://code.nsnam.org/ns-3-dev/file/ce0699130fc4/src/lte/model/lte-rlc-tag.cc
and the doxygen of ns-3.13 does not mention the class, as expected.

With the LENA code merge the scheduler API and implementations have completely
changes, hence the bug does not affect any more the lte module.
I am reassigning this to the wimax module for the maintainer to check whether
the wimax code is still affected by the bug.

What I am simulating in this case is a network with two cells: the
former has a variable number of UEs specified by the user as a command
line argument; the latter has a fixed number of UEs, i.e. 40. They also
share a part of their spectrum (I modified the spectrum management).
I introduced a couple of uniform variables to generate some
randomness: I randomly exchange eNB0 and eNB1 to make them
statistically equivalent. In this way, after a certain number of runs (a few
hundreds)
their performance in terms of total cell capacity is the same.

I didn't test the code on my ns-3, but looking at the code (i.e., dry check)
I'm ok with it.
I assume that everything is working as intended, tho.

Is the rp_filter setting the same on both systems? For example, see
the output of:
sysctl -a 2> /dev/null | grep '\(all\|default\)\.rp_filter'
The described behavior seems consistent with rp_filter being enabled
on the 64-bit system and disabled on the 32-bit system.
It would also help to clarify what interface is assigned 10.0.0.3/24.
It seems that the tapOutput interface created by the test case has the
address 10.0.0.2/24.

Subject: [Ns-bugs] [Bug 1422] valgrind error in ipv6-fragmentation test suite
In-Reply-To: 2012-05-21 18:32:39 EDT ---
I found the problem. It's not wise to use a Ptr<> to a SimpleRefCount as an
argument to a Simulator::Schedule.
The solution is not that simple, tho, as it means to change how the fragment
lost timeout is handled. By luck the IPv4 code is better at this (the event is
handled by the fragments and not by the outer class. Sorry if all this is kinda
obscure but I'm almost sleeping.
Tomorrow morning I'll make a patch.
T.
PS: and that's why when I copied the IPv6 fragment handling to make IPv4 one I
used a different way to handle the timeout. The IPv6 one didn't felt "right".
And I was right at not liking it.

Fix the valgring error
As I tought. It's not wise to launch an event with a SimpleRefCount Ptr as an
argument (or an Object either).
Also in this patch:
1) remove two unused and obscure mutable member variables from Fragments (both
IPv4 and IPv6) and
2) changed the name of an inner member variable whose name was the same as an
outer one
Number 1 is a remnant of extremely old SimpleRefCount implementation
(probably),
Number 2 is cosmetic but it can save some brain cells to go fishin' while
browsing the code.
Tested on a private Fedora release 16 (Verne). Jenkins seems to have some VMs
down. Need a confirm.

--- Comment #1 from Tommaso Pecorella 2012-05-24 17:13:51 EDT ---
This seems quite a bug, possibly only showing on MacOS and not on other systems
by luck (or unluck).
The piece of code responsible for this is in lte-rlc-am.cc, line 706:
if ( m_rxonBuffer[ m_vrMs.GetValue () ].m_pduComplete )
{
while ( m_rxonBuffer[ m_vrMs.GetValue () ].m_pduComplete )
{
m_vrMs++;
NS_LOG_LOGIC ("Incr VR(MS) = " << m_vrMs);
}
NS_LOG_LOGIC ("New VR(MS) = " << m_vrMs);
}
For some reason the cycle never ends. Well, the reason is that m_vrMs++ is
actually a modulus-based increment (at 1023 it goes back to 0) and when *all*
the elements in m_rxonBuffer have the m_pduComplete flag... the cycle will
never end.
I see two problems in this piece of code:
1) m_pduComplete is a map. If an element in the map is not there (is this
possible?) simply referencing it will create it. The "safe" function for this
case is map.find(key). See http://www.sgi.com/tech/stl/Map.html
2) there is no check about a complete map scanning, i.e., if the cycle is
complete.
Note: I found the problem using a complex MonteCarlo run analysis (I ran the
debugger and stopped it randomly 'til I found it was stuck in the same point).
I can *not* exclude similar issues elsewhere in the code.
I'm raising the bug priority, as it seems more than a simple test failing on a
particular OS.

According your description, it seems to be a bug in lte-rlc-am. I will take
care of it.

Luca, I wasn't able to run your test program against any LTE variants that I
had; it had a central-authority.h that I didn't know anything about.
Anyway, I created a subset of your program that I think results in a similar
nodal placement (initial node conditions). This new program runs against
ns-3-dev and I added it to this tracker.
I noticed that the program increments the x_bs value by 50 for each new eNB.
However, it seems that the ue are uniformly drawn from a range (-radius,
radius) in both X and Y dimensions. While eNB is at the origin, each
subsequent eNB is further away from the origin, and hence will be further away
from the population of UEs.
Do you think that this may account for what you observed?
Note that my version of the test program seems to be limited to two eNBs; if I
add a third eNB, all of the UEs assigned to it seem to be at the same place as
the eNB. What I wrote above is based on looking at the two eNB case.

Hi Vedran,
I agree that test headers should not be installed unless they are useful for
some other module. Also lte-simple-net-device.h and lte-simple-helper.h are not
meant to be used outside of the lte module, and if they really were meant to be
used, they should be moved to src/lte/model instead.
It seems however that it takes some effort to fix this, because of the many
interdependencies among files in src/lte/test, the need to add some forward
declarations, etc. I'll be able to work more on this issue tomorrow.

The attached path follows the recommendations of RFC 6298. Changes where made
on the calculation of the Retransmit Timeout estimation and on the process
followed on the retransmission, in case of a timeout. The AODV test, providing
as example, does not pass though :).

I'm wondering about splitting your patch for now, with the tcp-socket-base.cc
changes made now, and rtt-estimator.cc for further study (perhaps attached to
bug 1405).
The reason is that I'm wondering whether the rtt-estimator.cc changes are
aligned with the code in Measurement() and whether the code still conforms to
the algorithm advertised (mean deviation algorithm by Jacobson and Karels,
implemented with integer arithmetic), or is now a mashup of both algorithms.
For example,
- should smoothing be performed in RetransmitTimeout() if it is already done in
Measurement()?
- the new RetransmitTimeout() code doesn't use the variable "gain" but has
hardcoded values
- are the variables m_currentEstimatedRtt and m_srtt redundant?
Any thoughts on this proposal?

I'd split the issues as well (if possible).
It is even possible to have a different RTT estimator (the one we have is one
of the many possibilities), so a class name refactoring might be envisaged
(e.g.: RttEstimator -> JacobsonKarelsRttEstimator and the new one
RfcSomethingRttEstimator).

I moved Daniel's patch from bug 1399 here. It implements RFC 6298 behavior
(slightly different than the MeanDeviation algorithm currently implemented).
Another aspect that must be considered is whether the TCP or the RttEstimator
class maintains the state for the backoff. In the current design, RttEstimator
is managing all of this state, but in Daniel's patch, he moves the state for
managing backoff to the TcpSocketBase class.
I'm in favor of Daniel's proposal to make TCP manage the backoff state and just
have RttEstimator maintain actual estimates, but this would require removing
some state variables and the "multiplier" API from RttEstimator and should be
considered again once we are not close to a release deadline. The reason that
I am in favor of this is the separate proposal (bug 1412) that wants to reuse
RttEstimator for other protocols.

I made direct fix to the existing RttEstimator class for now (changeset
e3e89a0ccb7d) and moved your proposal to migrate the management of backoff
state to TcpSocketBase class (as well as create an RFC 6298 variant) to bug
1405, which can be worked post-release.

changing the title as it is reproducible on Linux also.
Would this be remedied by enabling bindings on the virtual-net-device module?
