raddec-balancer

Balance raddec traffic

Balance raddec traffic across an arbitrary number of targets based on a given strategy. The balancer ensures that any given transmitter is always mapped to the same target. Currently only a modulo strategy (based on transmitterId) is available, although the design supports any number of strategies in future. Typically used as part of a raddec-relay.

Installation

npm install raddec-balancer

Hello raddec-balancer!

The following code will run a single raddec through the balancer to determine to which of four targets it will be mapped (possible outputs are 0, 1, 2 or 3).

const RaddecBalancer = require('raddec-balancer');
const Raddec = require('raddec');
 
const NUMBER_OF_TARGETS = 4;
 
let balancer = new RaddecBalancer({ numberOfTargets: NUMBER_OF_TARGETS });
 
let raddec = new Raddec({
    transmitterId: "aa:bb:cc:dd:ee:ff",
    transmitterIdType: Raddec.identifiers.TYPE_EUI48
});
 
balancer.balanceRaddec(raddec, function(raddec, targetIndex) {
  console.log(targetIndex); // targetIndex = 3
});
