Systems and methods for seamless host migration
View Patent ↗Systems and methods of the present invention for maintaining network data distribution are provided. Network data may be distributed in such as manner as to allow a network session to weather interrupted communications between host and clients without significant loss of data. Embodiments of the present invention provide for one or more clients to serve as backup host(s) for the network session. When the other clients transmit data to the host, they may also transmit the data to one or more backup hosts if there are any indications of interrupted communication.
1. A method for migrating hosts in a network game environment, the method comprising:
evaluating network connections between a first computing device and a plurality of clients, wherein the first computing device hosts resources in the network game environment, and wherein evaluating the network connections comprises polling connectivity between the first computing device and the plurality of clients;
determining that migrating a responsibility for hosting the resources from the first computing device to a second computing device will increase network connectivity for the plurality of clients based on polling results that indicate a connectivity problem between the first computing device and the plurality of clients; and
instructing the first computing device to migrate the responsibility for hosting the resources to the second computing device determined not to have connectivity problems with the plurality of clients.
2. The method of claim 1 , wherein the determination is based on a network performance requirement.
3. The method of claim 2 , wherein the network performance requirement is a bandwidth level.
4. The method of claim 2 , wherein the network performance requirement is a quality of service level.
5. The method of claim 2 , wherein the network performance requirement is an ability to provide an acknowledgment of receipt in response to a received data transmission.
6. The method of claim 1 , wherein the determination is further based on network connectivity between the second computing device and the plurality of clients.
7. The method of claim 1 , wherein migration of responsibilities corresponds to migrating one or more tasks from a plurality of tasks associated with responsibilities for hosting the network game environment.
8. A host migration system, the system comprising:
a first computing device that hosts resources in a network game environment in accordance with an assigned responsibility for hosting the resources, the first computing device communicatively connected to a plurality of clients over the network;
a second computing device communicatively coupled to the network; and
a third computing device that stores executable instructions in memory, wherein execution of the instructions by a processor:
evaluates a network connectivity level associated with the plurality of clients, wherein evaluating the network connectivity comprises polling for connectivity between the first computing device and the plurality of clients,
determines that migrating the responsibility for hosting the resources from the first computing device to the second computing device will increase the network connectivity level of at least a portion of the plurality of clients based on polling results that indicate a connectivity problem between the first computing device and the plurality of clients, and
instructs the first computing device to migrate the responsibility for hosting the resources to the second computing device determined not to have connectivity problems with the plurality of clients.
9. The system of claim 8 , wherein the determination is based on a network performance requirement.
10. The system of claim 9 , wherein the network performance requirement is a bandwidth level.
11. The system of claim 9 , wherein the network performance requirement is a quality of service level.
12. The system of claim 9 , wherein the network performance requirement is an ability to provide an acknowledgment of receipt in response to a received data transmission.
13. A non-transitory computer-readable storage medium having a program embodied thereon, the program executable by a processor to perform a method for migrating hosts in a network game environment, the method comprising:
evaluating network connections between a first computing device and a plurality of clients, wherein the first computing device hosts resources in the network game environment, and wherein evaluating the network connections comprises polling for connectivity between the first computing device and the plurality of clients;
determining that migrating a responsibility for hosting the resources from the first computing device to a second computing device will increase network connectivity for the plurality of clients based on polling results that indicate a connectivity problem between the first computing device and the plurality of clients; and
instructing the first computing device to migrate the responsibility for hosting the resources to the second computing device determined not to have connectivity problems with the plurality of clients.
14. The non-transitory computer-readable storage medium of claim 13 , wherein the determination is based on a network performance requirement.
15. The non-transitory computer-readable storage medium of claim 14 , wherein the network performance requirement is a bandwidth level.
16. The non-transitory computer-readable storage medium of claim 14 , wherein the network performance requirement is a quality of service level.
17. The non-transitory computer-readable storage medium of claim 14 , wherein the network performance requirement is an ability to provide an acknowledgment of receipt in response to a received data transmission.
