Resource allocation request, method and system of allocation, optical network terminal and optical line terminal

Abstract

The embodiment of the invention provides a resource allocation request, a method and a system of allocation, an optical network terminal and an optical line terminal. In the method, the optical network terminal reports periodical information on performing inquiry of transmission unit queue use information to the optical line terminal; and the optical line terminal adjusts the period for sending request information on reporting an uplink dynamic bandwidth report to the optical network terminal, sends the request information on the uplink dynamic bandwidth report according to the adjusted period, and transmits dynamic bandwidth resources allocated to the optical network terminal according to a set mode. Through the resource allocation request, the resource allocation method, the resource allocation system, the optical network terminal and the optical line terminal, the accuracy for dynamic resources allocation in a passive optical network system is improved, the maintainability of the system is improved, and the abutting compatibility of the optical network terminal and the optical line terminal is increased.
