Abstract:
1. A system for the accelerated re-provisioning of data over cable service interface specification (DOCSIS) configuration files between a DOCSIS provisioning server and a plurality of optical network units (ONUs), comprising: a memory; a DOCSIS proxy configured to emulate DOCSIS provisioning for the ONUs according to the DOCSIS configuration files such that each ONU emulates a corresponding cable modem, wherein the DOCSIS proxy is configured to respond to an initial registration request sent from a given one of the ONUs to an optical line terminal by requesting a DOCSIS configuration file from the provisioning server and to decode the DOCSIS configuration file into an ONU configuration file; and a caching entity configured to monitor transmissions from the provisioning server of to the ONUs so as to store the ONU configurations files in the memory and to pass-through the ONU configuration files to the ONUs; the caching entity being further configured to monitor requests to the provisioning server for respective ones of the ONU configuration files from the ONUs, the caching entity being further configured to determine for each of the requests whether the requested ONU configuration file has been previously requested such that upon determining by the caching entity that the requested ONU configuration file has been previously requested by a given one of the ONUs, the caching entity retrieves the previously requested ONU configuration file from the memory and returns the retrieved-from-memory ONU configuration file to the given ONU.
