24e7f4a5a1 refactoring: OpenROADM: store the NF model of a premp/booster
All other noise models set the `nf_def` variable, so let's make the YANG
code simpler by remembering the amplifier NF model like that.

ce92d4e1b8 JSON: don't sleep when there are warnings in the input topology
Well, sleeping ain't fun. A red warning is plenty. In case of API
access, there's none, but that's just the APIs are.

e25e1fbe50 remove unused variable
It was only assigned to in `read_service_sheet`, and it's safe to remove
it also in `convert_service_sheet`.

fa834338ab Introduce OpenROADM preamp and booster models
The NF calculated by the preamp model is compliant with the MW-MW noise
mask in the OpenROADM MSA spec. The booster is noise-free, which is
modeled by setting the NF to zero (-inf in dB units). This is obviously
unphysical but it is the simplest way to model the total noise
contribution from a ROADM, including preamp and booster, that is
compliant with the the OpenROADM MSA.

This also introduces two new EDFA type varieties,
"openroadm_mw_mw_preamp" and "openroadm_mw_mw_booster" in the equipment
library. I would prefer to also change the names of the existing
"openroadm" type_def and "standard"/"low_noise" type_variety,
representing an OpenROADM inline-amplifier, for better consistency but
this probably needs to be discussed first.

01115f9852 Merge "Raise error when type_def for Edfa is not recognized" 2021-01-01 19:52:45 +00:00
Jonas Mårtensson
918c19b1bc Raise error when type_def for Edfa is not recognized
When loading the equipment file in json_io.py we should raise an error
if an Edfa type_variety specifies a NF type_def that is not
implemented. This should also allow to remove the assert statement in
the _nf method in the Edfa class.

27fd5cdad6 Error out on conflicting Fiber and RamanFiber definitions
The equipment library has, so far, used completely different namespaces
for `Fiber` and `RamanFiber` definitions. It was possible to define a
"SSMF" fiber whose properties, such as CD or PMD, would differ when used
as a Fiber vs. the RamanFiber object in the networking topology. That is
likely a bug of the equipment library, so this patch makes sure that a
configuration like that cannot be used.

I came across this when working on the YANG support where both fiber
types are defined in a common namespace, and the difference between them
is determined by lack or presence of a sub-container with the Raman
properties.

d3490ae30c Raise error if specified Edfa type_variety is missing in eqpt config
A recent patch introduced the possibility to define an Edfa in the
topology file without specifying its type_variety:

https://review.gerrithub.io/c/Telecominfraproject/oopt-gnpy/+/488967

But with the current implementation, if a user specifies a type_variety
that is missing from the equipment configuration file (e.g. because of
a spelling mistake) this is silently ignored and the type_variety is
instead selected by auto design. I think this is not desired since it
can lead to confusing results. This patch proposes to raise an error
when the specified type_variety is missing while still allowing the user
to not specify type_variety or set type_variety = '' for selection by
auto design.

A recently introduced test actually does exactly this, i.e. it defines
Edfas with type_variety = 'std_high_gain' even though this type variety
does not exist in the equipment config file used by the test. Therefore
this patch also modifies the topology file used by that test.

c56ea898a6 Add per degree channel power target out
- add the per degree info using the EXACT next node uid as identifier
  of the degree when a node is a roadm
- add the degree identifier on the propagate and on the call functions
- use the per degree target_pch_out_db defined in json entry for the
  target power in network build
- verifies existence of the per degree power target in order to support
  partial per degree target power definition
- correct test data files for expected auto design results that now
  should include the per degree information, even if it is the same
  for all degree.
- in order to enable per degree power definition on direction where
  booster is not defined, enable the declaration of edfas in json without
  specifying type variety

e6ee512001 Explicitly consider "system margins" instead of stashing them to transponder modes
Since 30234f913c, the code just added the
"system margins" to each transponder's minimal required OSNR. That's
simple and straightforward, but I think that mutating "equipment
library" in response to a "global simulation parameter" is not really
the right way to go.

Make this explicit; always check the resulting OSNR against the
transponder's minimum plus the margin.

I got into this when checking the fixups that are performed within the
JSON loader. I don't think that the JSON loader is an appropriate place
for this.

0efa0d310d Remove incomplete support for "fuzzy name matching"
This is something which got added in bc9eee32, but it never got
finalized to have a user-visible effect. To the best of my knowledge, it
only created a file which was never used.

I removed code which created that file in 0d542f22, so let's clean up
the rest.

I think this should also restore functionality of running convert.py in
a standalone mode. Looking at the ArgParser, the invocation never
considered the names_matching parameter.

754be7ca08 Do not create *_auto_design.json by default
It's a bad habit to write files into the source code repository. It will
also become impossible if gnpy is installed into a systemwide, possible
read-only location.

The old behavior can be reactivated by using an extra option to tell
GNPy where to put the generated file.

648039521e reorganization: move all JSON processing into an extra module
We agreed that `gnpy.core` should only contain stuff for propagating
wavelengths. Conceptually, JSON parsing and even instantiating these
network elements from data obtained through JSON is *not* something that
is on the same level -- and this will become more important when we move
into YANG format in future.

Also, instead of former `gnpy.core.equipment.common`, use
`gnpy.tools.json_io._JsonThing`. It is not really an awesome name :),
but I think it sucks less than a thing called "common" which would be no
really longer any "common" in that new file.
