Abstract: A method and apparatus for allocating a memory address in a resource-centric network are disclosed. The method of allocating a memory address may include receiving a request for a new service, determining whether the new service is able to be accommodated in a virtual memory that is pre-allocated in a resource-centric network, when the new service is able to be accommodated, allocating a memory area for accommodating the new service to the virtual memory, and when the new service is not able to be accommodated, allocating the memory area by using an additionally allocated area of a virtual memory of the resource-centric network.

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: A priority-based scheduling method and a scheduler configured to perform the method are disclosed. The priority-based scheduling method performed by a host of a memory separation network includes receiving a traffic load of queues divided according to priorities from a distributed memory configured to perform a load monitoring function, updating a throttle value of the queues divided according to the priorities at regular intervals, selecting a queue to transmit a request to the distributed memory from among all the queues divided according to the priorities, and adjusting a bandwidth of the selected queue by using the throttle value when the request of the selected queue is transmitted to the distributed memory.

Abstract: A system for cooperation of disaggregated computing resources interconnected through an optical circuit, and a method for cooperation of disaggregated resources are disclosed. Functional block devices such as a processor block, an accelerator block, and a memory fabric block exist at a remote location, and these three types of remote functional block devices are interconnected and interoperated in a specific program to perform a cooperative computation and processing process. Accordingly, the system shares data and information of a memory existing in each block through optical signal interconnection that provides low-latency, fast processing, and wide bandwidth, and maintains cooperation and memory coherency.
