Testing DNS effects on subscriber experience
Tags: DNS, Live, Service Provider Networks

What do you do when bandwidth isn’t the problem? One of the biggest reasons for poor subscriber experience (and as a result, more support calls) is not due to actual network speeds, but the perception of network speeds. This means that, although you may be delivering a high-speed connection on paper (and when the customer more »

Using XMPP for TR-069 Connection Requests
Tags: Home Router, Service Provider Networks, TR-069, XMPP

Though one of the fundamental principles of CWMP (TR-069) is that the CPE endpoint is always the one to initiate a connection, Autoconfiguration Servers (ACS) can use the TR-069 Connection Request feature to stimulate a CPE to begin a session. This is often used when the ACS must contact the CPE immediately, such as when more »

Broadband ISP Network Testing Group on LinkedIn

Is your device using valid TR-069 data models?
Tags: Home Router, Service Provider Networks, TR-069

The CPE WAN Management Protocol described by Broadband Forum TR-069 is a remote procedure call (RPC) based protocol. That is, it consists of two applications that interact directly with each other through a set of defined methods – in the case of TR-069, this includes device functions like Reboot, Download, etc., as well as operations more »

Testing devices with wireless WAN connections
Tags:

At QA Cafe we continuously see new consumer broadband and home network devices come into the market and into our lab. One of the newest class of devices are “travel routers” – routers that are popular with people who frequently connect to public Wifi networks or those offered by hotels, restaurants, or hospitals. These devices more »

The Misfortune Cookie and Security in the Home Gateway
Tags: Home Router, security, TR-069

Several months ago we talked about the revelations at DEFCON22 concerning web server security of systems meant to deploy TR-069 in a subscriber network. Most of the investigation done surrounded vulnerable ACS – that is, malicious attackers gaining access to the auto-configuration server, allowing them to control many hundreds of thousands of home devices. Recently, more »
