ostinato.protocols.ip4_pb2 module¶
To add and configure Ip4 in a stream, add a protocol to the stream, set the protocol id to ost_pb.Protocol.kIp4FieldNumber and access the Ip4 object from the Protocol object's Extensions dictionary using the key ip4_pb2.ip4
from ostinato.protocols import ip4_pb2
...
# stream is an object of type ost_pb.Stream
proto = stream.protocol.add()
proto.protocol_id.id = ost_pb.Protocol.kIp4FieldNumber
my_ip4 = proto.Extensions[ip4_pb2.ip4]
You can then set Ip4 attributes using my_ip4.<attribute>
