Disclosed herein a disaggregation computing system. The disaggregation computing system comprising: a local computing device that comprises a local processor, a local memory bus, a local memory and a local disaggregation controller; a remote computing device that comprises a remote processor, a remote memory bus, a remote memory and a remote disaggregation controller; and a disaggregation network that connects the local computing device and the remote computing device, wherein the local disaggregation controller and the remote disaggregation controller are configured to: check a response delay for access of the remote memory, and control the access of the remote memory based on the response delay.

Disaggregation computing system and method

A parallel scheduling apparatus includes an information managing unit generating a first request information for scheduling, a first scheduling unit performing first scheduling and then generating first matching information on the basis of the first request information, and a second scheduling unit performing second scheduling on the basis of the first request information and the first matching information. The parallel scheduling has an advantage of improving the scheduling performance and lowering the implementation complexity, ensuring low delay and transmission fairness among VOQs at low input traffic, being applied to all scheduling algorithms that perform existing multi-iterations, and providing efficient scheduling in a packet switch having a long RTT time or having a very short time slot or cell size, such as an optical switch.

Parallel scheduling method and parallel scheduling apparatus

A method and apparatus for providing a mobility in an Ethernet network. An Ethernet switch receives an Ethernet frame through a port of the Ethernet switch, and transmits the Ethernet frame to an upper Ethernet switch through a root port of the Ethernet switch based on whether a forwarding information for a destination address of the Ethernet frame exists in a forwarding table.

Methods and apparatus for providing mobility in ethernet network

Provided are a method for measuring an end-to-end delay, and asynchronous packet transmitter/receiver, capable of conveniently and exactly measuring a packet delay in an asynchronous packet transfer network in which a transfer priority is determined as in MPLS. The method includes the steps of continuously transmitting a higher priority packet and a lower priority packet at an ingress node, measuring a time when the higher priority packet arrives at an egress node, measuring a time when the lower priority packet arrives at the egress node, and calculating a delay time from the arrival time of the higher and lower priority packets. The higher and lower priority packets each include Coupled Label and Sequence Number fields for discriminating one of the packets that are repeatedly transmitted, the Coupled Label field of the higher priority packet is recorded with a label value of the lower priority packet, and the Coupled Label field of the lower priority packet is recorded with a label value of the higher priority packet.
