Abstract

Disclosed is a method for determining a traffic priority order on a network, which is suitable for efficient data transmission by determining priority order depending on multimedia data characteristics and normal data characteristics. The method for determining a traffic priority order on a network includes the steps of detecting the traffic generating frequency and/or the size of data being transmitted between respective stations, identifying data between respective stations as multimedia data if a traffic generating frequency and/or a data size is greater than a reference value, identifying data between respective stations as normal data if a traffic generating frequency and/or data size is lower than a reference value, granting the most significant priority order to multimedia data having traffic generating frequency and/or data size greater than corresponding reference values, determining whether a destination station can receive data or not, and reading data from a memory depending on priority order and transferring data to a destination station when that station is able to receive data.

Claims

1. A method for determining a traffic priority order for data to be transmitted over a network, comprising:

detecting traffic generating frequency between respective stations; and

granting priority order to data based on the detected traffic generating frequency, a higher priority order being granted when a higher traffic generating frequency is detected.

2. The method recited by claim 1, further comprising:

determining whether multiple data have been granted a same priority order.

3. The method recited by claim 2, further comprising:

changing a priority order among data determined to have been granted the same priority order, the priority order being changed based on an order that the data is received for transmission.

4. The method recited by claim 1, wherein the granting step comprises:

comparing the detected traffic generating frequency to a threshold, and

granting a most significant priority order to data when the detected traffic generating frequency exceeds the threshold.

5. The method recited by claim 4, further comprising:

determining that data for transmission between respective stations is multimedia data if the detected traffic generating frequency is greater than the threshold; and

determining that data for transmission between respective stations is normal data if the detected traffic generating frequency is lower than the threshold.

6. The method recited by claim 1, further comprising:

determining whether a destination station is ready to receive data;

reading data from a memory based on an associated priority order; and

transferring the read data to the destination station when the destination station is ready to receive data.

19. The method recited by claim 1, wherein the detecting step includes:

determining the traffic generating frequency over periods of time.

7. A method for determining a traffic priority order for data to be transmitted over a network, comprising:

detecting a size of data to be transmitted between respective stations; and

granting priority order to the data based on the detected data size, a higher priority order being granted when a greater data size is detected.

8. The method recited by claim 7, further comprising:

determining whether multiple data have been granted a same priority order.

9. The method recited by claim 8, further comprising:

changing a priority order among data determined to have been granted the same priority order, the priority order being changed based on an order that the data is received for transmission.

10. The method recited by claim 7, wherein the granting step comprises:

comparing the detected data size to a threshold, and

granting a most significant priority order to data when the detected data size exceeds the threshold.

11. The method recited by claim 10, further comprising:

determining that data for transmission between respective stations is multimedia data if the detected data size is greater than the threshold; and

determining that data for transmission between respective stations is normal data if the detected data size is lower than the threshold.

12. The method recited by claim 7, further comprising:

determining whether a destination station is ready to receive data;

reading data from a memory based on an associated priority order; and

transferring the read data to the destination station when the destination station is ready to receive data.

13. An apparatus for determining a traffic priority order for data to be transmitted over a network, comprising:

means for detecting information including at least one of a traffic generating frequency and a size of data to be transferred between respective stations; and

means for granting priority order to data based on the detected information, a higher priority order being granted when a higher information is detected.

14. The apparatus recited by claim 13, further comprising:

means for determining whether multiple data have been granted a same priority order.

15. The apparatus recited by claim 14, further comprising:

means for changing a priority order among data determined to have been granted the same priority order, the priority order being changed based on an order that the data is received for transmission.

16. The means recited by claim 13, wherein the granting means comprises:

means for comparing the detected information to a threshold, and

means for granting a most significant priority order to data when the detected information exceeds the threshold.

17. The apparatus recited by claim 16, further comprising:

means for determining that data for transmission between respective stations is multimedia data if the detected information is greater than the threshold; and

means for determining that data for transmission between respective stations is normal data if the detected information is lower than the threshold.

18. The apparatus recited by claim 13, further comprising:

means for determining whether a destination station is ready to receive data;

means for reading data from a memory based on an associated priority order; and

means for transferring the read data to the destination station when the destination station is ready to receive data.

20. The apparatus recited by claim 13, wherein when the detected information includes traffic generating frequency, the means for detecting detects the traffic generating frequency over periods of time.
