Dynamic content distribution protocol for an enterprise environment
Embodiments described herein provide a system for facilitating dynamic content distribution in an enterprise environment. During operation, the system receives, from a controller of the enterprise environment, an instruction for downloading a piece of content from one or more peers of a peer-to-peer protocol. The instruction can include a file descriptor that indicates a set of blocks the piece of content is divided into. The system can receive an offer for a first block of the set of blocks from a first peer of the one or more peers and determine whether the system is in a full peer relationship with a second peer of the one or more peers. The full peer relationship indicates that the second peer and the system are clients and servers of each other. If the system is in a full peer relationship, the system elects, between the second peer and the system, a sender for a first request that responds to the first offer.
1. A method for facilitating dynamic content distribution in an enterprise environment, comprising:
receiving, by a computing device from a controller of the enterprise environment, an instruction for downloading a piece of content from one or more peers of a peer-to-peer protocol, wherein the instruction comprises a file descriptor that indicates a set of blocks the piece of content is divided into;
receiving an offer for a first block of the set of blocks from a first peer of the one or more peers;
determining whether the computing device is in a full peer relationship with a second peer of the one or more peers, wherein the full peer relationship indicates that the second peer and the computing device are clients and servers of each other; and
in response to determining that the computing device is in a full peer relationship, electing, between the second peer and the computing device, a sender for a first request that responds to the first offer.
2. The method of claim 1 , further comprising sending a subscription request for the piece of content to the one or more peers based on the instruction.
3. The method of claim 1 , wherein in response to determining that the computing device is not in a full peer relationship, the method further comprises:
determining a first priority value associated with a peer relationship with the first peer; and
in response to the first priority value being lower than a threshold, backing off from sending the first request for a predetermined period of time.
4. The method of claim 3 , further comprising:
determining whether a second offer for the first block from a third peer has been received within the predetermined period of time;
determining whether a second priority value of the second offer is greater than the first priority value; and
in response to the second priority value being greater than the first priority value, sending a second request that responds to the second offer.
5. The method of claim 4 , wherein in response to not receiving the second offer or the second priority value not being greater than the first priority value, the method further comprises sending the first request.
6. The method of claim 1 , wherein in response to the computing device being elected as the sender, the method further comprises:
sending the first request to the first peer and sending a download notification message to the second peer; and
receiving the first block from the first peer.
7. The method of claim 6 , further comprising:
sending a third offer for the first block to the second peer; and
sending the first block to the second peer in response to receiving a third request that responds to the third offer.
8. The method of claim 1 , wherein in response to the second peer being elected as the sender, the method further comprises waiting for a predetermined period of time for a download notification message from the second peer.
9. The method of claim 8 , further comprising:
receiving a fourth offer for the first block from the second peer; and
sending a fourth request that responds to the fourth offer.
10. The method of claim 1 , further comprising determining whether the first peer is authorized to send an offer for the first block based on the file descriptor and an authorizations table, wherein the authorizations table maintains permissions for operations and resources of the enterprise environment.
11. A non-transitory computer-readable storage medium storing instructions that when executed by a computer cause the computer to perform a method for facilitating dynamic content distribution in an enterprise environment, the method comprising:
receiving, by a computing device from a controller of the enterprise environment, an instruction for downloading a piece of content from one or more peers of a peer-to-peer protocol, wherein the instruction comprises a file descriptor that indicates a set of blocks the piece of content is divided into;
receiving an offer for a first block of the set of blocks from a first peer of the one or more peers;
determining whether the computing device is in a full peer relationship with a second peer of the one or more peers, wherein the full peer relationship indicates that the second peer and the computing device are clients and servers of each other; and
in response to determining that the computing device is in a full peer relationship, electing, between the second peer and the computing device, a sender for a first request that responds to the first offer.
12. The computer-readable storage medium of claim 11 , wherein the method further comprises sending a subscription request for the piece of content to the one or more peers based on the instruction.
13. The computer-readable storage medium of claim 11 , wherein in response to determining that the computing device is not in a full peer relationship, the method further comprises:
determining a first priority value associated with a peer relationship with the first peer; and
in response to the first priority value being lower than a threshold, backing off from sending the first request for a predetermined period of time.
14. The computer-readable storage medium of claim 13 , wherein the method further comprises:
determining whether a second offer for the first block from a third peer has been received within the predetermined period of time;
determining whether a second priority value of the second offer is greater than the first priority value; and
in response to the second priority value being greater than the first priority value, sending a second request that responds to the second offer.
15. The computer-readable storage medium of claim 14 , wherein in response to not receiving the second offer or the second priority value not being greater than the first priority value, the method further comprises sending the first request.
16. The computer-readable storage medium of claim 11 , wherein in response to the computing device being elected as the sender, the method further comprises:
sending the first request to the first peer and sending a download notification message to the second peer; and
receiving the first block from the first peer.
17. The computer-readable storage medium of claim 16 , wherein the method further comprises:
sending a third offer for the first block to the second peer; and
sending the first block to the second peer in response to receiving a third request that responds to the third offer.
18. The computer-readable storage medium of claim 11 , wherein in response to the second peer being elected as the sender, the method further comprises waiting for a predetermined period of time for a download notification message from the second peer.
19. The computer-readable storage medium of claim 18 , wherein the method further comprises:
receiving a fourth offer for the first block from the second peer; and
sending a fourth request that responds to the fourth offer.
20. The computer-readable storage medium of claim 11 , wherein the method further comprises determining whether the first peer is authorized to send an offer for the first block based on the file descriptor and an authorizations table, wherein the authorizations table maintains permissions for operations and resources of the enterprise environment.
