Snappi Open Traffic Generator Python 包
项目描述
使用自动生成的 python SDK编写的测试脚本snappi可以针对任何符合Open Traffic Generator API的流量生成器执行。
Ixia-c就是这样一种开放流量生成器 API 的参考实现。
该存储库正在积极开发中，并会随时更新。将尽一切努力保持更新向后兼容。
在客户端上安装
python -m pip install --upgrade snappi
开始编写脚本
import snappi
# create a new API instance where location points to controller.
# this will use HTTP transport by default; in order to use gRPC instead,
# one can pass additional kwarg `transport=snappi.Transport.GRPC`
api = snappi.api(location='https://localhost')
# create a config object to be pushed to controller
config = api.config()
# add a port with location pointing to traffic engine
prt = config.ports.port(name='prt', location='localhost:5555')[-1]
# add a flow and assign endpoints
flw = config.flows.flow(name='flw')[-1]
flw.tx_rx.port.tx_name = prt.name
# configure 100 packets to be sent, each having a size of 128 bytes
flw.size.fixed = 128
flw.duration.fixed_packets.packets = 100
# add Ethernet, IP and TCP protocol headers with defaults
flw.packet.ethernet().ipv4().tcp()
# push configuration
api.set_config(config)
# start transmitting configured flows
ts = api.transmit_state()
ts.state = ts.START
api.set_transmit_state(ts)
# fetch & print port metrics
req = api.metrics_request()
req.port.port_names = [prt.name]
print(api.get_metrics(req))
