The cable network infrastructure is a shared medium that has been well-suited to support random, 'bursty' bandwidth demand from end users, thanks to its use of statistical multiplexing. As a result, the service quality on cable networks has generally been good.
However, the scope for bandwidth sharing between end users on the same statistical basis will diminish as the use of services that require sustained high bandwidth, such as Real-Time Entertainment streaming, grows. The measure of sustained bandwidth per end user, will become increasingly important for all Cable or MSO operators when dimensioning their network to maintain quality of service. It is obvious, due to the large number of subscribers behind DOCSIS Head-End, that Cable networks are already at their tipping point and need to find a way ahead.
The tenant association BRF Nejlikan has 37 apartments located in Stockholm. It is a single building, built in 1930 and the cable TV operator is providing Docsis 3.0 services. Among its tenants, young people demand sustainable Internet for gaming which cable operator can’t provide on high traffic hours.
BRF Nejlikan decided to have InCoax IP over Coax to provide higher sustained capacity. The building has municipal dark fiber from STOKAB and Internet is provided through ISP. From central fiber switch was a local Cat6 installed from basement to loft. One Head-End unit, Coax Link Controller is installed in the loft to provide IP connectivity to 37 apartments offering 100/100Mbps traffic.
