P4-NetFPGA-Split-and-Merge

Hardware implementation of Split-and-Merge metrics computation on the NetFPGA

How to build the NetFPGA-Split-and-Merge design

1. Install the P4->NetFPGA development environment following the information available at https://github.com/NetFPGA/P4-NetFPGA-public/wiki/Getting-Started
2. Create the p4 projects related to the simple and full implementation of the NetFPGA-Split-and-Merge design.

$ $SUME_SDNET/bin/make_new_p4_proj.py split_and_merge_simple
$ $SUME_SDNET/bin/make_new_p4_proj.py split_and_merge_full

3. Modify $SUME_FOLDER/tools/settings.sh to ensure that the P4_PROJECT_NAME environment variable is set to either split_and_merge_simple or split_and_merge_full, depending on which version you want to build. Run $ source settings.sh.
4. Clone this repo and move to the main folder.
5. Run either bash patch_simple.sh or bash patch_full.sh to copy the source files of the respective design in the proper directories of the original repo.
   Note: The patch must be applied everytime to switch between the simple and full versions, as some external modules must be updated accordingly.
6. Run bash run.sh to run the P4->NetFPGA workflow, generating the bitstream in $NF_DESIGN_DIR/bitfiles.
7. Control plane primitives to send control plane messages, process received ones and replay traffic traces are available for the Simple version in ${P4_PROJECT_DIR}/sw/hw_test
