Utility functions for drachtio-fsmrf
LoadBalancer
Class that allows you to select the least-loaded media server
const Srf = require('drachtio-srf');
const srf = new Srf();
const {LoadBalancer} = require('drachtio-fn-fsmrf-sugar');
const lb = new LoadBalancer();
/*
servers = [
{
address: '10.100.0.1',
port: 8021,
secret: 'ClueCon'
},
{
address: '10.100.0.2',
port: 8021,
secret: 'ClueCon'
}]
*/
// call this once to connect to the array of media servers
lb.start({servers, srf});
// then call this to get an array of available media server, with least loaded first
const mediaservers = lb.getLeastLoaded();
// mediaservers[0] is the least loaded
Methods are also provided to retrieve a specific media server by either its sip signaling IP address or the IP address that its event socket has bound to:
const ms = getMsBySipAddress(addr);
// or
const ms = getMsByEslAddress(addr);
The LoadBalancer emits a 'connect' event when at least one freeswitch is successfully connected.
