Method, apparatus, and computer-readable storage medium for network optimization of cloud storage service

1. A method for improving data availability of cloud storage service, comprising:

receiving, by a switch, a packet;

determining, by the switch, whether a destination Internet Protocol (IP) address of the packet is a reserved IP address, wherein the reserved IP address is an indicator that one or more copies of the packet need to be generated;

creating, by the switch, one or more copies of the packet upon determining that the destination IP address of the packet is the reserved IP address;

selecting, by the switch, a plurality of servers; and

separately forwarding, by the switch, the packet and the one or more copies to the plurality of servers to save the packet and the one or more copies on the plurality of servers such that in case of a server failure, data of the packet can be recovered from at least one of the plurality of servers.

2. The method of claim 1 , wherein the plurality of servers includes a predetermined number of servers, the predetermined number being determined based on a particular policy.

3. The method of claim 2 , further comprising replacing, by the switch, destination IP addresses of the packet and the one or more copies of the packet by respective server IP addresses of the plurality of servers.

4. The method of claim 1 , wherein selecting by the switch the plurality of servers comprises selecting the plurality of servers randomly.

5. The method of claim 1 , further comprising receiving, by the switch, an acknowledgement message (ACK) from a first server of the plurality of servers.

6. The method of claim 1 , further comprising:

creating, by the switch, an additional copy of the packet if the switch does not receive an acknowledgement message (ACK) from a first server of the plurality of servers within a predetermined period;

selecting, by the switch, a new server; and

forwarding, by the switch, the additional copy to the new server.

7. An apparatus for improving data availability of cloud storage service, comprising:

one or more processors;

a memory coupled to the one or more processors, the memory storing computer-readable instructions executable by the one or more processors that when executed by the one or more processors, cause the one or more processors to perform acts comprising:

receiving, by a switch, a packet;

determining, by the switch, whether a destination Internet Protocol (IP) address of the packet is a reserved IP address, and wherein the reserved IP address is an indicator that one or more copies of the packet need to be generated;

creating, by the switch, one or more copies of the packet upon determining that the destination IP address of the packet is the reserved IP address;

selecting, by the switch, a plurality of servers; and

separately forwarding, by the switch, the packet and the one or more copies to the plurality of servers to save the packet and the one or more copies on the plurality of servers such that in case of a server failure, data of the packet can be recovered from at least one of the plurality of servers.

8. The apparatus of claim 7 , wherein a predetermined number of servers, the predetermined number being determined based on a particular policy.

9. The apparatus of claim 8 , wherein the acts further comprise replacing, by the switch, destination IP addresses of the packet and the one or more copies of the packet by respective server IP addresses of the plurality of servers.

10. The apparatus of claim 7 , wherein selecting by the switch the plurality of servers comprises selecting the plurality of servers randomly.

11. The apparatus of claim 7 , wherein the acts further comprise receiving, by the switch, an acknowledgement message (ACK) from a first server of the plurality of servers.

12. The apparatus of claim 7 , wherein the acts further comprise:

creating, by the switch, an additional copy of the packet if the switch does not receive an acknowledgement message (ACK) from a first server of the plurality of servers within a predetermined period;

selecting, by the switch, a new server; and

forwarding, by the switch, the additional copy to the new server.

13. A computer-readable storage medium storing computer-readable instructions executable by one or more processors, that when executed by the one or more processors, cause the one or more processors to perform acts comprising:

receiving, by a switch, a packet;

determining, by the switch, whether a destination Internet Protocol (IP) address of the packet is a reserved IP address, wherein the reserved IP address is an indicator that one or more copies of the packet need to be generated;

creating, by the switch, one or more copies of the packet upon determining that the destination IP address of the packet is the reserved IP address;

selecting, by the switch, a plurality of servers; and

separately forwarding, by the switch, the packet and the one or more copies to the plurality of servers to save the packet and the one or more copies on the plurality of servers such that in case of a server failure, data of the packet can be recovered from at least one of the plurality of servers.

14. The computer-readable storage medium of claim 13 , wherein a predetermined number of servers, the predetermined number being determined based on a particular policy.

15. The computer-readable storage medium of claim 14 wherein the acts further comprise replacing, by the switch, destination IP addresses of the packet and the one or more copies of the packet by respective server IP addresses of the plurality of servers.

16. The computer-readable storage medium of claim 13 , wherein selecting by the switch the plurality of servers comprises selecting the plurality of servers randomly.

17. The computer-readable storage medium of claim 13 , wherein the acts further comprise receiving, by the switch, an acknowledgement message (ACK) from a first server of the plurality of servers.
