Changelog¶
3.4.1¶
- Updated test environment to Focal linux (from Xenial) to allow
dash
anddash-cytoscape
package import in CI/CD for visualization- Allows for moving WeatherMap from beta to production in future
- It’s no longer necessary to explicitly install the visualization requirements separately
- Heavy updates for docs
- Implemented black code formatting for local commits and in Travis CI/CD pipeline
- Implemented standard column name for RSVP LSP attribute to describe a manually assigned metric:
- FlexModel had
lsp_metric
column name in docstrings and examples - PerformanceModel had
manual_metric
column name in docstrings and examples - Standardized column name to
manual_metric
- This was a purely cosmetic change as the actual
manual_metric
is based on the column’s order in the table, not the specific column name
- FlexModel had
3.4.0¶
- This build, while functional, was yanked from pypi for reasons related to troubleshooting a new CI/CD pipeline. Let’s just say there was some drama around that, and the migration to travis-ci.com. These things happen.
- 3.4.0 features moved to 3.4.1 build
3.3.1¶
- Fixed bug in FlexModel to account for complex topology scenario involving ECMP demand paths with multipe IGP shortcut LSPs and parallel links
- Added spacing_factor as a WeatherMap configurable parameter
- Added another test to functional tests within test_parallel_link_model for complex topology
3.3¶
- Import of the WeatherMap class must be done from pyNTM.weathermap instead of directly from pyNTM. This prevents a warning message that is otherwise superficial unless you are using the WeatherMap class
3.2¶
- Fixed bug in WeatherMap class that caused scripts with WeatherMap to run 2x and to not be able to run a WeatherMap class live from the python3 CLI
3.1¶
- Removed automatic call of load_model_file class methods performing update_simulation() call automatically.
3.0¶
- WeatherMap class added as beta feature to provide interactive visualization of network topology. This is a beta feature and is not undergoing unit testing. This feature is supported in the python3 interpreter, but not in the pypy3 interpreter. This feature gives a very interactive and informative visualization of the topology
- path_detail Demand property support in all Model classes; provides clarity on how much traffic is passing on a given Demand’s path and how much of that traffic transits each component in the path
- Python 3.5 no longer supported
- Python 3.8 support added to unit/functional testing
- load_model_file class methods now perform update_simulation() call automatically. The update_simulation() call is only necessary to run after making a change to the topology after the model file has been loaded
2.1¶
- Enforcing tab-separated data in model data files (used to allow spaces or tabs between data entries)
- FlexModel class allows IGP RSVP shortcuts
- FlexModel and PerformanceModel classes allow/honor RSVP LSP manual metrics
- Made load_model_file for FlexModel and PerformanceModel classes more forgiving for number of lines allowed between tables
2.0¶
- Made version 1.7 into major version 2.0 to account for possible backwards compatibilty
1.7¶
- Renamed Model class to PerformanceModel
- Renamed Parallel_Link_Model class to FlexModel
- Optimization: general 18-25% performance improvement when measured by time to converge
- Moved common code from PerformanceModel and FlexModel to _MasterModel parent class
- Maintained unit testing coverage at 95%
- Cleaned up documentation/docstrings
1.6¶
- Added support for multiple links between nodes (Parallel_Link_Model)
- Cached parallel_lsp_groups in Model and Parallel_Link_Model objects (performance optimization)
- Added check for multiple links between nodes in Model object (not allowed)
- Added Parent Class _MasterModel to hold common defs for Model and Parallel_Link_Model subclasses
- Added simulation_diagnostics def in _MasterModel that gives potentially useful diagnostic info about the simulation results
- Simple user interface (beta feature) supports RSVP LSPs
1.5¶
- Updated code to account for networkx
- Improved some docstrings
1.4¶
- updated requirements.txt to allow use of beta features
1.3¶
- improved docstring for Model load_model_file class method
- updated requirements
- fixed bugs in beta features: visualization and simple UI
- updated unit testing
1.2¶
- added shared-risk link group (SRLG) support for Nodes and Interfaces
- added performance optimizations
- simplified sections of code
1.1¶
- added configured, fixed setup bandwidth capability on RSVP LSPs
- made small performance optimizations
1.0¶
- first release including pypi inetgration
