This project provides:

+ +
    +
  • A new driver (if_ptnet) for a paravirtualized network + device, modeled after the netmap API. The driver supports + multi-queue netmap ports, and it is able to work both in netmap + mode and in normal mode.
    • + +
  • The emulation of the ptnet device model as a module + of the bhyve hypervisor.
    • +
+ +

The ptnet device and driver has been introduced to + overcome the performance limitations of TCP/IP networking between + bhyve VMs. Prior to this work, the most performant solution for + VM-to-VM intra-host TCP communication provided less than 2 Gbps TCP + throughput. With ptnet, in the same VM-to-VM TCP + communication scenario, it is possible to obtain up to 20 Gbps.

+ + + + FreeBSD Foundation + + + + Share virtio-net header management code with the + if_vtnet driver. In the current code, about 100 lines of + code have been copied and pasted from if_vtnet.c. + +
