Replacing libc functions with DPDK functions #201

Closed dennisafa closed 3 years ago

dennisafa commented 4 years ago

Optimization

Describe the solution you'd like We use libc functions in some parts of our NF's and manager code. This includes calls like malloc or memcpy or strcpy. DPDK recommends using their own functions, as they are optimized for the data plane environment. We'd like to identify points in the critical datapath where these calls occur and replace them.

Documentation, Integration Strategy I recommend looking at our example NF's, particularly the pkt_handler function as that will be called the most. Replace the libc function calls with DPDK function calls if possible, referring to the API and note any performance benefits. It would also be worth looking at where these calls are used in the manager.

I've been working with @kevindweb on #200 . I think I could switch the libc functions as well.
