####TCP/IP stack for dpdk

Netdp is porting from FreeBSD TCP/IP stack, and provide a userspace TCP/IP stack for use with the Intel dpdk.

• librte_netdp: TCP/IP stack static library. netdp use dpdk mbuf, ring, memzone, mempool, timer, spinlock. so zero copy mbuf between dpdk and netdp.

• librte_netdpsock: Netdp socket lib for application, zero copy between netdp and application.

• netdp_cmd: Command for configure netdp tcp/ip stack.

• netdp_test: Example application with netdp for testing netdp tcp/ip stack

Support environment

• EAL is based on dpdk-1.7.1
• Development enviroment is based on x86_64-native-linuxapp-gcc
• TCP/IP stack is based on FreeBSD 10.0-RELEASE

Support feature:

• Netdp initialize
• Ether, zero copy between NIC and netdp TCP/IP stack.
• ARP, ARP timeout
• IP layer, IP fragmentation and reassemble
• Routing
• ICMP
• Commands for adding, deleting, showing IP address
• Commands for adding, deleting, showing static route
• Commands for showing ARP table
• UDP
• Socket layer
• No lock in UDP stack and socket layer.
• Running on multiple cores.

Next Planning

• Porting TCP from FreeBSD to netdp
• Porting socket from FreeBSD to netdp
• Open data plane.
• VxVLAN.
• Performance testing.
• IPFW
