DPDK-ANS基于 DPDK 的 TCP/IP 協(xié)議棧

ANS(Acceleted Network Stack) 是一個(gè)基于 DPDK 的 TCP/IP stack，可以運(yùn)行在 linux userspace。用戶可以自由添加、刪除ether 接口和IP地址，添加、刪除靜態(tài)路由。

支持的環(huán)境

• EAL is based on dpdk-1.7.0

• Development enviroment is based on x86_64-native-linuxapp-gcc

• TCP/IP stack is based on FreeBSD 10.0-RELEASE

支持的特性

• Netdp initialize

• Ether layer

• ARP

• IP layer

• Routing

• ICMP

• TCP

• UDP

• Commands for adding, deleting, showing IP address

• Commands for adding, deleting, showing static route

Testing

• TCP 連接建立釋放性能
