Simulating network errors for IPTV STB testing
2 posts · Closed
Hi,
I'm in charge of testing our new Videotron's IPTV Set-top-box and I need to simulate network errors and the impact of these errors on the video quality. Your Connection Emulator software seems to fulfill my needs and here is the way I think to use it:
TV--STB--Ethernet--PC with your software in bridge mode--WiFi interface--Internet gateway
and add errors to see the impact.
I tested the architecture without errors using Windows internal bridge and the STB is able to connect to video back-end and it takes up to a few minutes (DHCP, buffering, etc.).
I have an issue with activating the bridge mode on my laptop between my Ethernet interface connected to the STB and my Wi-Fi interface connected to the gateway. Searching in your forum, I found that Wi-Fi interfaces do not support promiscuous mode for monitoring (confirmed by Intel post for my particular laptop). Do you think I'll get more chance using a USB-Ethernet adapter connected to my laptop USB port to add another Eth interface?
Thanks
Yes, unfortunately bridging WiFi to Ethernet is not possible.
However, a USB Ethernet adapter should work fine, provided it supports promiscuous mode. Most adapters do, except the cheapest ones; please see this discussion USB to Ethernet Adapter and Promiscuous Mode.
