	var list = [];
	for (var j in ipList) 
		list.push({'ip': ipList[j], 'mac': macList[j], 'srtt': srttList[j] });

	list.sort(function(a, b) {
		return ((a.srtt < b.srtt) ? -1 : ((a.srtt == b.srtt) ? 0 : 1));
	});

	for (var k = 0; k < list.length; k++) {
		ipList[k] = list[k].ip;
		macList[k] = list[k].mac;
	    srttList[k] = list[k].srtt;
	}
