Abstract

Methods and systems are disclosed for providing approaches to enhanced task coordination in distributed systems. The methods and systems may include receiving, by a first computing device, a command for a client device and determining whether the first computing is connected to the client device. The methods and systems may include that if the first computing device is not connected to the client device, then transmitting, from the first computing device, a first message to a database associated with the cluster, the first message including the command and a device state of the first computing device, transmitting, from the database, a second message to a second computing device of the cluster, the second message including the command and the device state of the first computing device, and transmitting, from the second computing device and based on the device state of the second computing device, the command to the client device.

Claims

1. A method comprising:

receiving, by a first computing device of a cluster of computing devices, a command for a client device;

determining whether the first computing device of the cluster is connected to the client device;

if the first computing device is not connected to the client device;

transmitting, from the first computing device, a first message to a database associated with the cluster, the first message including the command and a device state of the first computing device;

transmitting, from the database, a second message to a second computing device of the cluster, the second message including the command and the device state of the first computing device; and

transmitting, from the second computing device and based on the device state of the second computing device, the command to the client device; and

if the first computing device is connected to the client device, then transmitting the command from the first computing device to the client device.

2. The method of claim 1, wherein the command comprises an instruction for one or more client devices and the first message comprises a broadcast message, the method further comprising:

transmitting, from the database, the second message to one or more computing devices of the cluster connected to the one or more client devices.

3. The method of claim 1, wherein the command comprises an instruction for one or more client devices and the first message comprises a multicast message, the method further comprising:

transmitting, from the database, the second message to all of the computing devices of the cluster.

4. The method of claim 1, wherein transmitting the second message to the second computing device of the cluster is responsive to the second computing device receiving a real-time notification from the first computing device.

5. The method of claim 1, wherein the first computing device or the second computing device comprises an oldest computing device of the cluster.

6. The method of claim 1, wherein the command comprises a security command.

7. The method of claim 1, wherein the first computing device and the second computing device are not connected to the client device, the method further comprises:

transmitting a broadcast message to the database, the broadcast message including the command for the client device and the device states of the first computing device and the second computing device; and

transmitting, from the database, a third message to a third computing device of the cluster connected to the client device, the third message including the command and the device states of the first computing device and the second computing device.

8. A system, comprising:

at least one processor; and

at least one memory storing computer-readable instructions that, when executed by the at least one processor, cause the system to perform;

receiving, by a first computing device of a cluster of computing devices, a command for a client device;

determining whether the first computing device of the cluster is connected to the client device;

if the first computing device is not connected to the client device;

transmitting, from the first computing device, a first message to a database associated with the cluster, the first message including the command and a device state of the first computing device;

transmitting, from the database, a second message to a second computing device of the cluster, the second message including the command and the device state of the first computing device; and

transmitting, from the second computing device and based on the device state of the second computing device, the command to the client device; and

if the first computing device is connected to the client device, then transmitting the command from the first computing device to the client device.

9. The system of claim 8, wherein the command comprises an instruction for one or more client devices and the first message comprises a broadcast message, wherein the computer-readable instructions further cause the system to perform transmitting, from the database, the second message to one or more computing devices of the cluster connected to the one or more client devices.

10. The system of claim 8, wherein the command comprises an instruction for one or more client devices and the first message comprises a multicast message, wherein the computer-readable instructions further cause the system to perform transmitting, from the database, the second message to all of the computing devices of the cluster.
