Weekly Progress

Week 1 (July 27 - August 3, 2018)

• Discussion with guide about SDN and P4.

Week 2 (August 4 - 10, 2018)

• Literature survey on SDN and P4.

Week 3 (August 11 - 17, 2018)

• Literature survey on NS4.
• Completed setting up the GitHub repository for the project.

Week 4 (August 18 - 24, 2018)

• Completed the set-up of NS4 environment.
• Ran few example programs successfully.

Week 5 (August 25 - 31, 2018)

• Facing issues in environment set up for P4.

Week 6 (September 1 - 7, 2018)

• Tried contacting the authors of NS4 paper for contribution ideas, but didn't get any reply.

Week 7 (September 8 - 14, 2018)

• Successfully set-up the virtual machine for p4 in our laptop.
• Facing issues in running tutorial examples given in p4 repository.
• Logged in to the 'gian' account in a system in lab and tried using the p4 environment set up during the GiAN course last December. It worked fine, and we plan to use the same for future development.
• Contacted Khursheed Ali regarding the issues faced.
