April 2024 - This site, and Kamaelia are being updated. There is significant work needed, and PRs are welcome.


Simple multicast sender

A simple component for sending data to a multicast group.

Remember that multicast is an unreliable connection - packets may be lost, duplicated or reordered.

Example Usage

Multicasting a file to group address on port 1000 (local address port 0):

Pipeline( RateControlledFileReader("myfile", rate=100000),
          Multicast_sender("", 0, "", 1000),

More detail

Data sent to the component's "inbox" inbox is sent to the multicast group.

This component ignores anything received on its "control" inbox. It is not yet possible to ask it to shut down. It does not terminate.

This component never emits any signals on its "signal" outbox.


class Multicast_sender(Axon.Component.component)

Multicast_sender(local_addr, local_port, remote_addr, remote_port) -> component that sends to a multicast group.

Creates a component that sends data received on its "inbox" inbox to the specified multicast group.

Keyword arguments:

  • local_addr -- local address (interface) to send from (string)
  • local_port -- local port number
  • remote_addr -- address of multicast group to send to (string)
  • remote_port -- port number


  • control : NOT USED
  • inbox : Data to be sent to the multicast group


  • outbox : NOT USED
  • signal : NOT USED

Methods defined here


You should be using the inbox/outbox interface, not these methods (except construction). This documentation is designed as a roadmap as to their functionalilty for maintainers and new component developers.

__init__(self, local_addr, local_port, remote_addr, remote_port)

x.__init__(...) initializes x; see x.__class__.__doc__ for signature


Main loop
