Converged Edge Services Access Router (CESAR)

March 07, 2011 |

CESAR is a project led by Time Warner Cable Inc. that shares many similarities with the aims of the Comcast Corp.-led Converged Multiservice Access Platform (CMAP) effort.

CESAR, like CMAP, targets the creation of dense edge products that support traditional RF-based cable services with newer IP-based offerings, including IP video. Both look to combine cable modem termination system (CMTS) and edge QAM functions in the same device.

Among possible differences, TW Cable may ask vendors to produce smaller chassis than Comcast is specifying in its CMAP products. Also, TW Cable claims it has yet to form a bias regarding fully integrated or modular versions of CESAR, though most industry observers see the MSO leaning toward integrated products. However, TW Cable says it's open to multi-vendor, modular designs so long as the suppliers handle the integration headaches that come along with them.

TW Cable has not revealed when CESAR will enter the request for proposal (RFP) phase. CMAP product field trials, however, are expected to start in late 2011 and early 2012.
