ostinato.protocols.tcp_pb2 module¶

To add and configure Tcp in a stream, add a protocol to the stream, set the protocol id to ost_pb.Protocol.kTcpFieldNumber and access the Tcp object from the Protocol object's Extensions dictionary using the key tcp_pb2.tcp

from ostinato.protocols import tcp_pb2
...
# stream is an object of type ost_pb.Stream
proto = stream.protocol.add()
proto.protocol_id.id = ost_pb.Protocol.kTcpFieldNumber
my_tcp = proto.Extensions[tcp_pb2.tcp]

You can then set Tcp attributes using my_tcp.<attribute>
