Abstract:
1. In a passive optical network (PON) implementing shared access between at least one central unit and a plurality of end-stations, a dynamic bandwidth allocation (DBA) processor comprising: a. a DBA co-processor, for performing and accelerating DBA functions, that includes: b. a central processing unit (CPU) core is logically coupled to the DBA co-processor through a CPU bus and operative to configure and dynamically control all DBA co-processor units and to run sections of algorithms that cannot be accelerated on the DBA co-processor; wherein the PON data-path receive bus and the PON data-path transmit bus bypass the CPU core; and whereby the DBA processor provides both the flexibility of a CPU and the strength of dedicated hardware acceleration in dynamic allocation of bandwidth in the communications network.
