Abstract

According to an aspect of present invention provides method of controlling a packet transmission interval, method comprising, comparing a preset delay ratio with number of packets transmitted, transmitting packets until number of packets transmitted becomes equal to or greater than delay ratio, calculating a delay request time when number of packets transmitted becomes equal to or greater than delay ratio, generating a signal for suspending packet transmission during calculated delay request time, suspending packet transmission according to generated signal and calculating a gap time based on a difference between a time when suspension of packet transmission was terminated and packet transmission was started and updating the delay ratio using the calculated gap time and initializing the number of packets transmitted.

First claim

What is claimed is:

1 . A method of controlling a packet transmission interval, the method comprising:
comparing a first delay ratio with a number of packets transmitted; transmitting packets until the number of packets transmitted becomes equal to or greater than the first delay ratio; calculating a delay request time when the number of packets transmitted becomes equal to or greater than the first delay ratio; generating a signal for suspending the packet transmission during the calculated delay request time; suspending the packet transmission according to the generated signal and calculating a gap time based on a time difference between when the suspension of the packet transmission was terminated and when the packet transmission was resumed; and updating the first delay ratio to a second delay ratio using the calculated gap time and initializing the number of packets transmitted.

2 . The method of claim 1 , further comprising transmitting packets until the initialized number of packets transmitted becomes equal to or greater than the second delay ratio.

3 . The method of claim 1 , wherein the second delay ratio is obtained by dividing the gap time by the first delay ratio.

4 . The method of claim 1 , wherein the calculating of the delay request time comprises calculating the delay request time by multiplying the first delay ratio by a preset delay time.

5 . The method of claim 4 , wherein the preset delay time is a time interval between transmissions of individual packets at a preset transmission speed.

6 . The method of claim 1 , wherein the first delay ratio can be changed according to at least one of network bandwidth, size of data to be transmitted, and central processing unit (CPU) resources allocated to an application.

7 . An apparatus for controlling a packet transmission interval, the apparatus comprising:
a comparison unit which compares a first delay ratio with a number of packets transmitted; a packet transmission unit which transmits packets until the number of packets transmitted becomes equal to or greater than the first delay ratio; a delay request time calculation unit which calculates a delay request time when the number of packets transmitted becomes equal to or greater than the first delay ratio; a delay processing unit which generates a signal for suspending packet transmission during the calculated delay request time; a gap time calculation unit which calculates a gap time based on a time difference between when the suspension of the packet transmission was terminated and when the packet transmission was resumed; and a transmission speed control unit which updates the first delay ratio to a second delay ratio based on the calculated gap time and initializes the number of packets transmitted.

8 . The apparatus of claim 7 , wherein after the first delay ratio is updated and the number of packets transmitted is initialized, the packet transmission unit transmits packets until the initialized number of packets transmitted becomes equal to or greater than the second delay ratio.

9 . The apparatus of claim 7 , wherein the second delay ratio is obtained by dividing the gap time by the first delay ratio.

10 . The apparatus of claim 7 , wherein the delay request time calculation unit calculates the delay request time by multiplying the first delay ratio by a preset delay time.

11 . The apparatus of claim 7 , wherein the preset delay time is a time interval between transmissions of individual packets at a preset transmission speed.

12 . The apparatus of claim 7 , wherein the first delay ratio can be changed according to at least one of network bandwidth, size of data to be transmitted, and CPU resources allocated to an application.

13 . A computer program which is coupled to a computing device and stored on a non-transitory medium to execute comparing a first delay ratio with a number of packets transmitted; transmitting packets until the number of packets transmitted becomes equal to or greater than the first delay ratio; calculating a delay request time when the number of packets transmitted becomes equal to or greater than the first delay ratio; generating a signal for suspending packet transmission during the calculated delay request time; suspending the packet transmission according to the generated signal and calculating a gap time based on a time difference between when the suspension of the packet transmission was terminated and when the packet transmission was resumed; and updating the first delay ratio to a second delay ratio using the calculated gap time and initializing the number of packets transmitted.
