A parallel processing method for a traffic having an order, which supports virtual core automatic scaling in a virtual environment having at least one virtual machine (VM) and at least one virtual core queue for each VM, may comprise identifying a flow of the traffic according to attributes of the traffic; determining a virtual core queue to which the traffic is mapped according to the identified flow and queuing the traffic to the determined virtual core queue; and transferring the traffic from the determined virtual core queue to a VM corresponding to the determined virtual core queue through a virtual switch. Also, traffic belonging to a same flow may be queued to a same virtual core queue and processed by a same virtual core.

Parallel processing method supporting virtual core automatic scaling and apparatus therefor

Provided is a device and a method for providing network virtualization, in which a method of dynamically mapping a processor includes extracting tenant information on a tenant and information on a virtual machine (VM) generated by a Cloud OS or controller; classifying virtual machine queues (VMQs) and processors to process the VMQs by tenant, and dynamically mapping the VMQs onto the processors by tenant.

Device and method for dynamically mapping processor based on tenant

An apparatus and a method for mapping of a tenant based dynamic processor, which classify virtual machine multi queues and processors processing the corresponding multi queues for each tenant that one or more virtual machines are belonged to, dynamically map the virtual machine multi queues that belong to the corresponding tenant to multi processors that belong to the corresponding tenant based on total usages of a network and a processor for each tenant to provide network virtualization to assure network traffic processing of virtual machines that belong to the same tenant not to be influenced by congestion of network traffic that belongs to another tenant.

Apparatus and method for mapping of tenant based dynamic processor

This invention is directed to a TS(Transport Stream) multiplexing apparatus capable of accommodating plurality of PES(Packetized Elementary Stream). The present invention provides a transport stream multiplexing apparatus which is capable of multiplexing in only one transport stream multiplexing apparatus plurality of PES streams transmitted from the respective encoders by simplifying an interface between the encoders and the transport stream multiplexing apparatus by means of a PCI bus. A transport stream multiplexing apparatus of the present invention comprises a PCI interface processor for transmitting distinctly plurality of stream transmitted through a PCI bus; control signal processor for outputting a selection signal, an input signal and a transmission control signal; media buffer for outputing a transport stream packet and a transport stream payload; timing processor for outputting a timing signal required for outputting a packet; multiplexing controller for outputting a transport stream header output signal; header processing means for outputting header data in response to the transport stream header output signal; and multiplexor for multiplexing the transport stream packet and the transport stream payload input from the media buffer and outputting the transport stream packet.
