Abstract

According to an embodiment, there is provided a communication apparatus including: a first acquiring unit, a determining unit and a second acquiring unit. The first acquiring unit acquires first data from a first acquisition destination upon receiving an acquisition request of the first data from a requester. The determining unit determines second data required for the requester by analyzing the first data acquired by the first acquiring unit and then determines whether the second data exists in a data storage accessible from the requester, the data storage being arranged inside or outside the communication apparatus. The second acquiring unit acquires the second data from a second acquisition destination when it is determined the second data does not exist in the data storage.

Claims

1. A communication apparatus comprising:

a first acquiring unit to acquire first data from a first acquisition destination upon receiving an acquisition request of the first data from a requester;

a determining unit to determine second data required for the requester by analyzing the first data acquired by the first acquiring unit and then determine whether the second data exists in a data storage accessible from the requester, the data storage being arranged inside or outside the communication apparatus; and

a second acquiring unit to acquire the second data from a second acquisition destination when it is determined the second data does not exist in the data storage.

2. The communication apparatus according to claim 1, wherein the determining unit detects data specified within the first data and determines the data as the second data.

3. The communication apparatus according to claim 1, wherein identification information of data is specified within the first data,

the determining unit detects the identification information in the first data and determines data identified by the identification information as the second data,

the determining unit determines, if the data identified by the identification information is stored in the data storage, whether there is such possibility that the data identified by the identification information in the data storage is different from data held by the second acquisition destination and identified by the identification information, and

the second acquiring unit acquires the second data from the second acquisition destination when it is determined there is such possibility by the determining unit.

4. The communication apparatus according to claim 1, wherein the first acquiring unit transmits the first data acquired from the first acquisition destination to the requester, and

the second acquiring unit transmits the second data acquired from the second acquisition destination to the requester upon receiving a request given from the requester.

5. The communication apparatus according to claim 4, wherein the first acquiring unit transmits the first data acquired from the first acquisition destination to the requester after the second acquiring unit has acquired the second data.

6. The communication apparatus according to claim 1, wherein the second acquiring unit stores the second data acquired from the second acquisition destination in the data storage.

7. The communication apparatus according to claim 1, wherein the determining unit reads information related to data held in the data storage from an information storage arranged inside or outside the communication apparatus and determines, based on the information read from the information storage, whether the second data exits in the data storage or not.

8. The communication apparatus according to claim 7, wherein the determining unit reads the information via an internal bus from the information storage.

9. The communication apparatus according to claim 7, wherein the information storage is provided inside the communication apparatus.

10. The communication apparatus according to claim 9, wherein the data storage is provided inside the communication apparatus.

11. The communication apparatus according to claim 1, wherein the determining unit, after the first acquiring unit has acquired the first data, queries the requester to determine whether the second data exists in the data storage.

12. The communication apparatus according to claim 1, further comprising a receiving unit to receive an acquisition request of the first data from the requester via an internal bus, and the first acquiring unit carries out acquiring the first data when the receiving unit receives the acquisition request of the first data.

13. The communication apparatus according to claim 1, wherein the communication apparatus is a network interface card or a memory card.

14. The communication apparatus according to claim 1, wherein the requester, the first acquiring unit, the determining unit and the second acquiring unit are configured on a semiconductor integrated circuit.

15. The communication apparatus according to claim 1, further comprising the requester,

wherein the requester is configured to transition to a low power consumption status during at least a part of period during which the second acquiring unit performs an operation of acquiring the second data.

16. The communication apparatus according to claim 1, further comprising a receiving unit to receive an acquisition request of the first data from the requester via a wireless network or a wired network.

17. A communication method performed in a communication apparatus, comprising:

acquiring first data from a first acquisition destination upon receiving an acquisition request of the first data from a requester;

determining second data required for the requester by analyzing the first data acquired and then determining whether the second data exists in a data storage accessible from the requester, the data storage being arranged inside or outside the communication apparatus; and

acquiring the second data from a second acquisition destination when it is determined the second data does not exist in the data storage.

18. A non-transitory computer readable medium having instructions stored therein which causes, when executed by a processor, the processor to execute processing of steps comprising:

acquiring first data from a first acquisition destination upon receiving an acquisition request of the first data from a requester;

determining second data required for the requester by analyzing the first data acquired and then determining whether the second data exists in a data storage accessible from the requester, the data storage being arranged inside or outside the communication apparatus; and

acquiring the second data from a second acquisition destination when it is determined the second data does not exist in the data storage.
