Abstract:
Provided is a method of delivering, by a device, packets to an application installed on the device the method including: obtaining information regarding a delivery mode determination condition, the information being used to determine a delivery mode of delivering the packets to the application; determining a delivery mode of delivering the packets based on the obtained information regarding the delivery mode determination condition; receiving packets to be delivered to the application through a network interface of the device; and delivering, to the application, the packets to be delivered according to the determined delivery mode.
Abstract:
A method of distributing data includes: determining a core and a queue of a network interface card for processing data transmitted from the device, from among a number of cores in a server; determining a source port of the device for transmitting data to the determined core or the determined queue of the network interface card, by using an inverse-hash function of a hash function that is used by the server; and transmitting the data to the server, via the determined source port.
Abstract:
A method of managing data includes controlling to form packed bucket data by packing user data and a pointing map indicating a storage location of the user data; controlling to extract a specific key value that is to be browsed by a user from the packed bucket data; and exchanging the specific key value through a smart interface.
