Summary

Internet access networks in general and wireless mesh access networks (WMNs) in particular, are the bottleneck of today's communication networks and consequently most strongly responsible for determining the user satisfaction. The limited bandwidth and the fact that access network are most often used as mere bit pipes are however unfavorable for the users' quality of experience (QoE). The lack of application-specific service guarantees is especially inadequate in the face of an increasing degree of heterogeneity of Internet applications like YouTube, Skype, Cloud Storage, or IPTV, and their individual service requirements. Application and quality of experience resource management, Aquarema for short, addresses this challenge by enabling application specific network resource management and thereby improves the user QoE. This is achieved by the interaction of application comfort (AC) monitoring tools, running at the clients, and a network advisor which may trigger different resource management tools. AC quantifies how well an application is running and in particular, enables a prediction of the user experience, thereby allowing the network advisor to act upon an imminent QoE degradation. The software-suite AquareYoum realizes this concept for the application YouTube in a WMN which is connected to the Internet via several Internet gateways. AquareYoum enables a disturbance-free playback of a YouTube video by predicting an imminent video stalling and consequently moving the YouTube flow to a less congested Internet gateway.

YoMo

YoMo 3.4 is available for download from the G-Lab website.

Screencast

The following two screencasts capture the AuareYoum demonstration given at EuroView 2010 and KiVS 2011. They demonstrate the AquareYoum functionality which allows a successful YouTube video playback in a congested wireless mesh network.

Attention: Screencast 1 has a file size of 92 MB in high quality, Screencast 2 is above 100 MB.
The screencasts will not start before 30% of the content are prebuffered and will probably not work for slow Internet connections. Please choose the appropriate quality according to your Internet connection.
