Mobile backhaul networks today support Ethernet microwave transport for 3G and 4G wireless technology services alongside legacy 2G and 3G TDM-based microwave equipment. However, as late as 2009 these wireless network services were solely TDM transport. One of the primary benefits of moving to Ethernet microwave transport has been the inherent statistical multiplexing (stat mux) gains. Stat mux relies on the fact that not everyone is “talking” at the same time and when they do, their IP radio packet sizes are variable, whereas networks based on TDM have to be provisioned statically for peak rates to individual wireless microwave sites.
With the advent of Ethernet, the typical practice is to oversubscribe all the wireless network services (based on individual peak rates) knowing that there is a statistical improbability of hitting the peak rate across all your wireless communication towers at the same exact moment.
Now enter video streaming where data is “streamed” between two wireless communication points over a sustained period (e.g., 30-second YouTube video clips, Skype HD Video Conferencing, Netflix movies). The sustained aspect of these video streams begins to strain the overall stat mux paradigm. Not only does video remain sustained but also it uses large-size IP radio packets that do not vary greatly. VoIP does the same thing, but the effect is much less significant as the overall bandwidth utilization is much lower.
Oversubscription becomes more challenging the more active video streaming is at any given moment. Imagine a scenario where the latest cat-playing-a-piano video gets posted online and everyone starts viewing it at virtually the same time. For a large swath of bandwidth, stat mux will reach zero for approximately four minutes. The upside is that you can add more bandwidth and/or offer differentiated wireless network services levels that guarantee certain bandwidth or application performance. Even so, video streaming does not totally negate the benefits of an Ethernet microwave transport, it just needs to be properly understood and managed to ensure a consistent user experience across all applications and services for your global wireless solutions.
