Abstract
This disclosure describes techniques for provisioning a CMTS to re-direct customer traffic into virtualized network functions (NFVs) service chains. This disclosure describes, in one example, techniques for providing linkage between DOCSIS service flows and NFV service chains in the DOCSIS provisioning system by embedding information within cable modem boot files used to configured cable modems within the broadband system. In one example, the techniques facilitate the definition of an NFV service-chain in the DOCSIS cable modem boot file provisioning system. A supported CMTS, CCAP or Edge Router intercepts and interprets the configuration to install packet classifiers that steer specific subscriber flows, as detailed in the DOCSIS cable modem boot file, through the service-chain.
