byteblowerll.byteblower.ByteBlowerPort¶

class byteblowerll.byteblower.ByteBlowerPort(*args, **kwargs)¶

Logical representation of a network host docked somewhere in the NUT, which can transmit or schedule network traffic, process incoming traffic and run stateful network applications.

A ByteBlowerPort is physically connected (or ‘attached’) to the NUT through the physical ByteBlower interface on which it is created. See ByteBlowerServer.PortCreate() for more information.

Multiple ports may be created on the same physical interface. From a network view, they are just different (simulated) hosts within a shared (datalink or layer 2) subnet. This means traffic to one port created on an interface is seen by all ports on that interface.

Most test scenarios start with one or more ByteBlower ports that are configured to do the following things:

become part of the network (layer2, layer3, perform DHCP, join multicast groups, …)
schedule network traffic streams for transmission (TX objects)
configure incoming packet processors (RX objects) that look for matching packets and e.g. count them
start network applications such as HTTP servers
schedule network application actions (called ‘schedulable objects’) such an HTTP client application sending out an HTTP request

When such ports are subsequently activated, the scheduled streams and network actions are performed at the configured time.

From that moment, relevant result data may be pulled from those streams (TX statistics), incoming packet processors (RX statistics) and network applications (application and session statistics).

Destroying a port will clean up everything that is configured on that port in a clean way:

streams, incoming packet processors and network applications are teared down, their results are gone
the port leaves all multicast groups of which it is part (but doesn’t wait for confirmation)
the port releases its DHCP lease (but doesn’t wait for confirmation)

__init__(*args, **kwargs)¶: Initialize self. See help(type(self)) for accurate signature.
