[Rift] Negative disaggregation implemented

[Bruno Rijsman <[e-mail]>]

Mariano Scazzariello and Tommaso Caiazzi informed me that they completed the implementation negative disaggregation in the open source RIFT-Python implementation (including new unit tests).

I want to extend a heart-felt “thank you very much!” to Mariano and Tommaso for their excellent work and their generous contribution of this important feature!  

I wish them good luck in using the newly implemented code in their further research on Kathará (https://www.youtube.com/watch?v=ionEpKjv3Vk <https://www.youtube.com/watch?v=ionEpKjv3Vk>) and Megalos (https://www.youtube.com/watch?v=XvInh-kujrA <https://www.youtube.com/watch?v=XvInh-kujrA>).

I have merged all of their code into my master branch: https://github.com/brunorijsman/rift-python <https://github.com/brunorijsman/rift-python>

My next steps are:

1) Do additional testing off negative disaggregation and polish up the code if needed.

2) Update the meta-topology generation tools to support east-west links in multi-plane topologies.

3) Write a feature guide for negative disaggregation, similar to the existing feature guide for positive disaggregation (https://github.com/brunorijsman/rift-python/blob/master/doc/positive-disaggregation-feature-guide.md <https://github.com/brunorijsman/rift-python/blob/master/doc/positive-disaggregation-feature-guide.md>).

4) Write an article on disaggregation (positive or negative) and submit for publication in the Internet Protocol Journal or similar.

5) Do interoperability testing with Juniper.
