Abstract: Provided are apparatus and method for slicing resources in passive optical network systems. The method includes identifying network elements included in a plurality of physical passive optical networks (pPONs), abstracting the identified network elements so that the identified network elements are recognized as the same software (SW) block, generating a plurality of PON slices by performing PON slicing on the abstracted network elements in accordance with a predetermined reference, and generating a plurality of virtual PONs (vPONs) by mapping the plurality of PON slices to at least one network element. The predetermined reference is determined on the basis of an attribute of at least one of ports and transmission containers (T-CONTs) corresponding to the identified network elements, and the at least one network element includes an optical network unit (ONU).

Abstract: A protection switching method and apparatus based on a memory control in a packet transport system are provided. The protection switching method may perform hardware-based protection switching based on a type of path failures that occur. The protection switching method may perform protection switching for each of an Automatic Protection Switching (APS) frame or a Loss of Continuity (LoC)/Clear Loss of Continuity (CLoC) message received via an interface unit from a packet processor, a LoC/CLoC message received via a local bus interface from a host processor, an APS frame generation command input via the local bus interface from protection software (SW) of the host processor, and an APS frame generation command input via another interface unit from the protection SW.
