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

Project Task Page: Multicast Proxy Tools


Status: Stasis
Current active developer:
Current dev locations: /Sketches/MPS/Systems/MulticastProxying
Start Date: 9 June 2006
Expected date: n/a
end date: n/a

Estimated effort so far: 1/2 man day

This task aims to produce tools to make it simpler to join multicast islands together - in essence tools for proxying multicast over non-multicast enabled networks.

A direct end result of this is that it would enable someone to take a multicast stream, send it to a proxying hub, allow clients to connect to this multicast hub, and those clients would then remulticast that stream within a local (eg corporate intranet) network for local availability.
This task was created because it was deemed to be hopefully useful to a particular internal client at the BBC.
Some specific benefits of working on this include:

Interested Third Parties


The expected scenario for these components is that there are situations as follows:

This is a non-exhaustive set of input states.

Relevant Influencing factors:




Code Produced:
These tools already exist in the subversion repository in /Sketches/MPS/Systems/MulticastProxying. Files in that directory and purpose:

Defines the following config options

mcast_group, mcast_port - The multicast group/port to be proxied
mcast_tcp_splitter_ip, mcast_tcp_splitter_port - IP/port of a simple TCP Splitter that serves the contents of a given multicast group to people who connect
tcp_tcp_splitter_ip, tcp_tcp_splitter_port - IP/port of a TCP Splitter that accepts a data source from a single TCP client
tcp_splitter_client_ip, tcp_splitter_client_port - IP/port of the TCP Splitter where clients can connect to recieve that data source





****Realistic possibilities arising as a result of activity on this task ****

The creation of tools that allow for automated mesh setup building on this allow for the realistic possibility of merging application layer multicast with IP level multicast.
