Testing LAN clients with Public IP addresses in CDRouter

In a typical home network, the ISP assigns a single Public IPv4 address to the CPE device that can be reached from the global Internet. The device assigns Private IPv4 addresses to CDRouter’s LAN clients and acts as an Internet gateway to them by mapping all of the Private addresses to the one Public address using Network Address Translation (NAT). (Private IPv4 addresses are described in RFC 1918, eg. 192. Read more...

Testing devices with wireless WAN connections

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 let you preserve network settings that your devices need, let you set up default connections to VPNs or other secure networks, and act as an additional level of firewall security when connecting to public networks.

Testing a Wifi Range Extender or Wifi Mesh System

Devices that enhance consumer Wifi are becoming more and more prevalent, both off the shelf and deployed by service providers. A Wifi booster or Wifi range extender is sometimes a simple repeater, but more often they act as layer 2 bridges, and can still be tested for performance and management via TR-069 or SNMP. Isolating a node in a Wifi mesh When there are multiple repeaters forming a mesh, as is the case with a lot of consumer Wifi systems , it’s best to isolate the DUT that you want by telling CDRouter which BSSID in the mesh to connect to.

What should you test in Wifi mesh enabled routers?

Of all of the things about broadband service that is most keenly felt by the end user, it’s the quality of their Wifi networks. Wifi is unique in that it is a complex networking system that users are aware of, and make purchasing decisions for consumer electronics and for broadband service around it. Realizing this, many companies are building Wifi products that specifically target the consumer rather than relying on the provider to deploy Wifi service, using Wifi mesh technology to deploy quality, reliable Wifi throughout the user’s home or business.

Exploring scaling tests - Is your home gateway IoT ready?

By now we’ve all heard of the coming flood of network aware devices collectively referred to as the “Internet of Things”. While the term encompasses a wide variety of use cases that are not all clearly defined, we can come up with some rudimentary expectations on how this influx of connections will affect networks. For the home gateway, the most significant impact is how to handle an order of magnitude more connections than most are traditionally designed for - how well does it scale? Read more...

IP Multicast Testing with CDRouter

This guide describes the IP multicast testing features in CDRouter and the role of IGMP (Internet Group Management Protocol) in CPE networks. CDRouter supports multicast testing using IGMP version 3. Although many CPE devices have support for IP multicast and IGMP, new functional requirements for set-top boxes and other IPTV multicast applications are pushing the adoption of IGMPv3 into the CPE networking space. IGMPv3 in CPE Networks Several different industry technology bodies including the Broadband Forum and CableLabs (DOCSIS) have defined the use of IGMPv3 for CPE devices. Read more...

Testing TR-069 LAN side CPE with CDRouter

The CDRouter TR-069 add-on module for CDRouter has the ability to test LAN-side devices, as defined in TR-181i1. TR-069 LAN-side devices are typically set-top boxes or VoIP endpoints that reside on the LAN side of the customer’s Internet Gateway Device (IGD) which may or may not support TR-069. The CDRouter TR-069 add-on supports automated testing for LAN-side devices. You can use this test setup to: Easily test TR-069 enabled LAN-side devices such as set-top boxes (STB) or voice-over-IP (VoIP) endpoints Can be used to test devices that are operating in both load-balancing mode or failover mode Automated PD-128 and data model profile testing for LAN-side devices CDRouter can test LAN devices that support Broadband Forum TR-104 (VoIPService data model), TR-135 (STBService data model), TR-196 (FAPService data model), TR-140 (StoargeService data model), and TR-181i1/i2 (Device root data models).
