Optimizing Performance in DOCSIS 3.0 Networks

Through mounting pressure from competitors and customers, most cable and multiple system operators (MSOs) have a dual challenge: they must both increase the bandwidth of data services and improve the quality of service (QoS) for voice. And with the heightened demand for IPTV services, MSOs are under additional pressure to improve their network infrastructure.

To meet these goals, the key technology in the Data Over Cable Service Interface Specification (DOCSIS) 3.0 is high-order channel bonding (also known as wideband technology). By aggregating up to 4 channels in the upstream (US) and 8 channels in the downstream (DS), operators can deliver the bandwidth required to better compete with fibreto- the-home (FTTh/FTTx) technology. In addition, increasing channel count within a bonding group is the key to better QoS for voice services when network loads increase through statistical multiplexing.
