Claim 0:
1. A digital network communication method comprises:
receiving from at least one passive optical network (PON) interface router out of a plurality of PON interface routers at a PON optical line terminal (OLT), at least one private data stream out of a plurality of data streams, wherein said at least one private data stream has been virtually separated using Virtual Routing and Forwarding (VRF) to form at least one virtually separated private data stream comprised of Internet Protocol (IP) data packages, and wherein said at least one virtually separated private data stream including said IP data packages is intended for at least one of a plurality of Optical Network Units (ONUs), and wherein said at least one of a plurality of ONUs serves at least one network device of a plurality of network devices;
aggregating within said PON OLT said plurality of data streams and said at least one virtually separated private data stream into a common data feed;
distributing said common data feed to said plurality of ONUs; wherein said distributing comprises:
replicating said common data feed using at least one optical splitter connected to said plurality of ONUs; and,
delivering said common data feed to said plurality of ONUs;
extracting within said at least one of said plurality of ONUs, said at least one virtually separated private data stream including said IP data packages from said common data feed;
sending said at least one virtually separated private data stream including said IP data packages from said at least one of said plurality of ONUs to said at least one network device of a plurality of network devices;
generating returning IP data packages at said at least one network device;
delivering to said at least one of said plurality of ONUs, at least one virtually separated data stream including said returning IP data packages generated by said at least one network device;
receiving at said at least one of said plurality of ONUs, said at least one virtually separated data stream including said returning IP data packages;
sending said at least one virtually separated private data stream including said returning IP data packages, from said at least one of said plurality of ONU's to said OLT, where said sending comprises:
feeding said at least one virtually separated private data stream including said returning IP data packages to said at least one optical splitter connected to said plurality of ONUs;
converging at said at least one optical splitter said at least one virtually separated private data stream including said returning IP data packages, with returning IP data streams from said plurality of ONUs into a returning common data feed;
delivering said returning common data feed from said at least one optical splitter to said PON OLT;
extracting at said PON OLT said at least one virtually separated private data stream including said returning IP data packages; and,
sending said at least one virtually separated private data stream including said returning IP data packages to a next network equipment destination.
