Multicastify

Multicastify is a multicast proxy that allows the use of multicast in environments that don't generally support it (namely AWS). It works by listening to the multicast loopback, and sending datagrams to a [Redis] pub/sub. Messages received from the Redis pub/sub are replayed on the local loopback. The application is written in node.js and deployed through NPM.

Dependencies

• Node.js > 0.10.0
• Python >2.5 and <3.0

Installation

To use the release version, simply run npm install multicastify -g.

To install from source:

• npm install git://github.com/liveops/multicastify.git

Usage

Multicastify has helpful documentation built in to the command line. You will need to specify at least one Redis server IP and port and a multicast IP and port.

Multicastify has two primary arguments, the redis node(s) and the multicast address to proxy.

Options:
  -v, --version                            Print version and exit.
  -S IP:PORT, --redisNode IP:PORT          Redis to use as pub/sub. Use option more than once for HA operation.
  -a IP:PORT, --multicastAddress IP:PORT   Multicast IP address and port to bind (eg. 224.0.0.1:5100). Can be used more than once.

Example

Single redis on localhost: multicastify --redisNode localhost:6379 --multicastAddress 225.0.0.1:48812

Clustered Redis: multicastify -S 172.17.8.101:6379 -S 172.17.8.102:6379 -a 225.13.13.1:48812

TODO

• IPv6 support
• Change log level as a command line parameter
• Port for use with AMQ/ZMQ topics
• Allow override of the pub/sub channel name from the command line
