Snap: When Click Meets GPU
A heterogeneous parallel packet processing engine with GPU computing. Aiming
at 10Gbps line rate complex packet processing. Now can reach ~30Gbps SDN
forwarding, IDS router at 64B packets and 40Gbps starting from 128B on an
overclocked Core i7 930 machine with GTX 480 or Tesla C2075.
Snap is still under development, master branch doesn't contain the latest
unstable change, checkout other topic branches such as "mrg" for new
functionality and elements.
Some notes:
- All batched elements are in elements/local/
- I/O related and Netmap Snap elements are in elements/userlevel/
- PacketBatch is in lib/
- No stable rule parser available. I used to modify classifier or lookup
elements directly to get binary format rules/routing table.
- userlevel/click.cc has been modified for RSS pin.
- lib/packet.cc modified for per-thread pool.
