硬件：Intel® Atom™ CPU C3758 @ 2.20GHz， 4G内存， 4核，1G网卡
软件：ubuntu16.04， vpp18.10
TRex双向线速发64字节的小包。

测试二层报文

拓扑如下：

待测vpp设备配置：
startup.conf

cpu {
         main-core 1
         corelist-workers 0,2,3
}

vppctl set interface l2 bridge TenGigabitEthernet7/0/0 10
vppctl set interface l2 bridge TenGigabitEthernet7/0/1 10

TRex发包器配置：
vi /etc/trex_cfg.yaml

- port_limit      : 2
  version         : 2
#List of interfaces. Change to suit your setup. Use ./dpdk_setup_ports.py -s to see available options
  interfaces    : ["07:00.0","07:00.1"]
  port_info       :  # Port IPs. Change to suit your needs. In case of loopback, you can leave as is.

     - dest_mac  : "c4:00:ad:a2:02:fb"
       src_mac   : "c4:00:ad:a2:02:fa"
     - dest_mac  : "c4:00:ad:a2:02:fa"
       src_mac   : "c4:00:ad:a2:02:fb"

测试结果如下：

TRex 1G网卡线速发包1.5Mpps,VPP基本线速转发，不丢包

Debug版本测试结果如下：

可以看得出Debug版本性能会下降很多。

测试三层报文

拓扑如下：

TRex发包器配置

- port_limit      : 2
  version         : 2
#List of interfaces. Change to suit your setup. Use ./dpdk_setup_ports.py -s to see available options
  interfaces    : ["07:00.0","07:00.1"]
  port_info       :  # Port IPs. Change to suit your needs. In case of loopback, you can leave as is.
         - ip    : 10.10.10.100
           default_gw : 10.10.10.1
         - ip    : 90.10.10.100
           default_gw : 90.10.10.1

测试结果如下：

线速转发
