Abstract

A system for package pre-fetching for a remote program installation includes a service node having a processor, a computing node type database, and a cache, the service node being configured to receive at least one package request for a package required for an installation of an operating system and at least one peripheral application thereof from a computing node, and determine a package request sequence by which the computing node issues the at least one package request according to a type of the computing node. In another embodiment, a method includes receiving a package request from a computing node, and determining a package request sequence by which the computing node issues at least one package request according to a type of the computing node, so as to pre-read a subsequent package into a cache before the computing node issues a request for the subsequent package.

Claims

1. A system for package pre-fetching for remote program installation, the system comprising:

a service node comprising a processor, a computing node type database, and a cache, the service node being configured to;

receive at least one package request for a package required for an installation of an operating system and at least one peripheral application thereof from a computing node; and

determine a package request sequence by which the computing node issues the at least one package request according to a type of the computing node.

2. The system as recited in claim 1, wherein the service node is further configured to pre-read a subsequent package from an external storage device into the cache prior to the computing node issuing a request for the subsequent package.

3. The system as recited in claim 1, wherein the service node is further configured to store identification information of each computing node in a computing node type database in an association with a computing node type.

4. The system as recited in claim 3, wherein the identification information is an address.

5. The system as recited in claim 3, wherein the service node is further configured to search for a corresponding computing node type in the computing node type database in order to determine the package request sequence.

6. The system as recited in claim 5, wherein the corresponding computing node type is determined by the identification information stored in the computing node type database.

7. The system as recited in claim 1, wherein the service node is further configured to construct a request sequence database based on one or more previous package requests from a computing node, the request sequence database being configured to store a plurality of package request sequences corresponding to each type of computing node.

8. The system as recited in claim 1, wherein the service node further comprises a request sequence database for storing a package request sequence corresponding to each type of computing node.

9. The system as recited in claim 1, further comprising the computing node, wherein the computing node is configured to issue the package request for installing the operating system and the at least one peripheral application associated with the operating system, based on an internal installation configuration file.

10. The system as recited in claim 1, further comprising an external storage device coupled to the cache, wherein the service node is further configured to read a subsequent package, following a requested package from the external storage device, into the cache while returning the requested package to the computing node.

11. The system as recited in claim 10, wherein the service node is further configured to read all of the request packages other than a first package in the package request sequence from the external storage device into the cache at one time after receiving a first package request from the computing node and acquiring the package request sequence corresponding to the computing node type.

12. The system as recited in claim 1, wherein the service node is further configured to:

search the cache to determine whether the requested package is in the cache after receiving a package request from the computing node;

read the requested package from an external storage device into the cache; and

read the requested package from the cache.

13. A method for implementing package pre-fetching for remote program installation, the method comprising:

receiving a package request for a package required for an installation of an operating system and at least one peripheral application thereof from a computing node; and

determining a package request sequence by which the computing node issues at least one package request according to a type of the computing node, so as to pre-read a subsequent package into a cache before the computing node issues a request for the subsequent package.

14. The method as recited in claim 13, further comprising:

storing identification information of each computing node in a computing node type database in an association with a computing node type;

determining identification information of the computing node issuing the package request; and

searching for a corresponding computing node type in the computing node type database, determined by the identification information stored in the computing node type database.

15. The method as recited in claim 13, further comprising pre-reading a subsequent package from an external storage device into the cache prior to the computing node issuing a request for the subsequent package.

16. The method as recited in claim 13, further comprising:

storing identification information of each computing node in a computing node type database in an association with a computing node type, wherein the identification information comprises an address; and

searching for a corresponding computing node type in the computing node type database in order to determine the package request sequence,

wherein the corresponding computing node type is determined by the identification information stored in the computing node type database.

17. The method as recited in claim 13, further comprising constructing a request sequence database based on one or more previous package requests from a computing node, the request sequence database being configured to store a plurality of package request sequences corresponding to each type of computing node.

18. The method as recited in claim 13, further comprising reading a subsequent package into the cache, following a requested package from an external storage device coupled to the cache, while returning the requested package to the computing node.

19. The method as recited in claim 18, further comprising reading all of the request packages other than a first package in the package request sequence from the external storage device into the cache at one time after receiving a first package request from the computing node and acquiring the package request sequence corresponding to the computing node type.

20. The method as recited in claim 13, further comprising:

searching the cache to determine whether the requested package is in the cache after receiving a package request from the computing node;

reading the requested package from the external storage device into the cache; and

reading the requested package from the cache.
