+Overview:
+=========
+
+
+This project aims to create an Open Source catalog for reference and
+classification of Virtual Network Functions (VNFs)s available on
+Internet. The classification method proposed will be in sync with the
+requirements of Telcos active in NFV landscape. The project aims to have
+running web platform similar to [1] by the mid of internship (2nd week
+of March). By the penultimate month of internship I aim to have fully
+functional implementation of an Open Source VNF in functest.
+
+
+Problem Statement:
+------------------
+
+OPNFV aims to be the reference platform for development,
+standardization and integration of Open Source NFV components across
+various Open Source Platforms. It mainly deals with the infrastructure
+through the Network Function Virtualization Infrastructure (NFVI) and
+Virtual Infrastructure manager (VIM). The MANO (Management and
+orchestration) stacks have been introduced recently. VNFs are not
+directly in OPNFV scope, however VNFs are needed to test and qualify the
+infrastructure. In this regard having a common curated Open Source
+Reference VNF catalog would be of immense importance to community.
+
+Since major focus of OPNFV is Telcos, a curated platform targeted from
+industry point of view would be very useful. We plan to divide the
+entire project into three major phases(with some iterative improvements
+and overlaps)
+
+
+Curation Phase
+--------------
+This phase pertains to studying various Open Source VNFs available and
+classification of them based on certain parameters. The parameters that
+I currently have in mind are:
+ * Developer Metrics: These pertain to repo characteristics of VNF under
+ study
+  * Usage Statistics - Activity, Number of Commits, stars
+  * Maturity Statistics - For instance if an NFV community decides code
+  coverage is important for them, it shows the NFV community is serious
+  about taking the project forward
+ * Technical Tagging: These are the tags that pertain to technical
+ characteristics of a VNF
+  * Broad Use Cases - Whether the VNF fits strictly in IaaS, PaaS or
+  SaaS layer or is an hybrid of two/all.
+  * Generic Use Cases - This in my opinion is the broadest
+  classification category. For instance a VNF could be built with a
+  broad idea of powering IOT devices at home or from usage perspective
+  of Telco Operators (vFW, vEPC, vIMS, vCDN, vAAA, vCPE,...).`[2]`_
+  * Fields of Application
+  * Library Status - Whether APIs are standardized, support RESTful
+  services.
+  * Dependency Forwarding Graph - This is pretty complex tagging
+  mechanism. It essentially tries to establish a graph relationship
+  between the VNFs (elementary VNFs are used in Service Function
+  Chaining chains such as Firewall, DPI, content enrichment,..). In my
+  opinion this is useful immensely. This will allow users to go to
+  platform and ask a question like - “I have this X tech stack to
+  support, Y and Z are my use cases, which NFVs should I use to support
+  this.
+  * Visitor Score - Based on `[1]`_ I plan to evolve a visitor score for
+  the platform. This will allow users to score an NFV on certain
+  parameters, may be post comments.
+
+**I plan to use the above three scores and evolve cumulative score which
+will be displayed next to each of the NFV on the platform.**
+
+ * Platform building phase - This will involve erecting a Web Platform
+ which will be similar to this  `[1]`_. I am decently familiar with
+ Django and hence I will write the platform in Django. There are two
+ action plans that I have in mind right now. Either I can start writing
+ the platform simultaneously which will help keep track of my progress
+ or I can write the platform after 1.5 - 2 months into the internship.
+ Either way I aim to have the Web Platform ready by March 12.
+
+ * Functest VNF implementation phase - This is the last phase that will
+ involve writing a fully functional implementation of an Open Source VNF
+ into Functest. I will undertake this after I am 3 months into the
+ internship. I have a decent familiarity with python and hence I think
+ it shouldn’t be too difficult. I need to decide how complex the VNFI
+ should undertake this exercise for (e.g. AAA such as free radius sounds
+ relatively easy, vCDN is much more challenging).
+ This will be decided in consent with my mentors.
+
+
+
+
+Schedule:
+=========
+I plan to take this project in 6 months time frame as I want to use it
+as a chance to read more about NFVs in particular and SDN in general

+| December 12 - January 12 | Study the above mentioned metrics        |
+|                          | Decide which of them are important for   |
+|                          | community (and which are not).           |
++--------------------------+------------------------------------------+
+| January 12 - January 27  | Make a database for the above studied    |
+|                          | metrics and evolve it further based on   |
+|                          | Mentors’ input. + associated API         |
++--------------------------+------------------------------------------+
+| January 27 - February 5  | Compile the data collected above and make|
+|                          | it public. Although I can keep everything|
+|                          | public from the beginning too. My        |
+|                          | rationale of not making the entire data  |
+|                          | public in initial stage as the errors    |
+|                          | caused by me could be misleading for     |
+|                          | developers.                              |
++--------------------------+------------------------------------------+
+| February 5 - March 5     | Erect the Web Platform and release it    |
+|                          | for restricted group for alpha testing.  |
++--------------------------+------------------------------------------+
+| March 5 - March 12       | Make it public. Release it to public for |
+|                          | beta testing. Fix Bugs.                  |
++--------------------------+------------------------------------------+
+| March 12 - April 12      | Start working on implementation of an    |
+|                          | Open Source VNF in Functest.             |
++--------------------------+------------------------------------------+
+| April 12 - May 12        | I will decided what to do here based on  |
+|                          | discussion with mentors.                 |
