Abstract: Disclosed are a disaggregated data center resource management method and apparatus. A resource management method in a disaggregated data center includes receiving a resource allocation request from a client; generating allocated resource information about a computing resource and a memory resource which configure a virtual server in one rack of the data center according to the resource allocation request and optical path setting information for optical path connection of the computing resource and the memory resource; updating a resource management table for the computing resource and the memory resource; and transmitting a resource connection setting message including the allocated resource information and the optical path setting information to the computing resource and the memory resource.

Abstract: A passive optical network (PON) method and device using network sharing are disclosed. The PON slicing method includes identifying network elements included in a plurality of physical PONs (pPONs), abstracting the identified network elements to be recognized as a same software block, generating a plurality of virtual PONs (vPONs) according to a user requirement using the plurality of pPONs, and mapping the generated plurality of vPONs by performing PON slicing on the abstracted network elements.

Abstract: Disclosed is a communication method, a zone scheduler performing thereof, and an inter-zone scheduling coordinator (IZSC). A communication method performed by a zone scheduler may include transmitting an inter-zone scheduling request to an IZSC in response to an occurrence of an inter-zone traffic with respect to another zone scheduler, receiving an inter-zone matching pattern and information on a time slot from the IZSC, and transmitting the inter-zone traffic to the other zone scheduler by performing scheduling based on the inter-zone matching pattern in the time slot.

Abstract: An optical switching control method and apparatus. The method includes generating an optical switching path corresponding to a destination node of service traffic flowing from an external service network, generating an optical frame corresponding to the generated optical switching path, transmitting, to a control server, a request message for requesting an allocation of a time slot to transmit the generated optical frame, generating an optical signal having a predetermined wavelength to transmit the optical frame in response to an admission message being received as a result of admission with respect to the request message, and transferring the optical frame to the destination node based on the optical switching path using the generated optical signal.

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 scheduling method for switching including receiving an allocation request for a time slot from input nodes to which the time slot is not allocated, receiving property information of at least one of virtual output queues (VOQs) in which data received by the input nodes is stored, determining a transmission priority of the VOQs for transmission of the data stored in the VOQs based on the received property information of the VOQs, determining input nodes to which the time slot is to be allocated using outputter arbiters for output nodes corresponding to the VOQs, allocating the time slot to the determined input nodes, and updating elements used to allocate the time slot with respect to input nodes for which the allocating of the time slot is completed and output nodes for which the allocating of the time slot is completed.
