Enhanced retry method
View Patent ↗A method of re-establishing communication between a control device and an unaddressed test device connected in a network is provided. The method includes: maintaining a plurality of network addresses of nodes within the network, at the control device; resending a lost message, comprising sending a plurality of command messages, each including a command sent in the lost message and having a destination address different from a destination address of the lost message, wherein the plurality of network addresses comprises the destination addresses of the plurality of command messages; and, receiving an acknowledgement message from the unaddressed test device at the control device.
1. A method comprising:
maintaining, by a device, a plurality of network addresses of nodes within a network;
determining, by the device, that a first message transmitted to a test device is lost;
sending, by the device and based on determining that the first message is lost, a plurality of second messages,
each second message of the plurality of second messages including a command sent in the first message and including a respective destination address of a plurality of destination addresses,
each respective destination address being different than a destination address of the first message, and
the plurality of network addresses including the plurality of destination addresses; and
receiving, by the device and based on sending the plurality of second messages, an acknowledgement message from the test device,
the acknowledgement message being used to identify a particular destination address, associated with the test device, used for transmitting a third message to the test device.
2. The method of claim 1 , further comprising:
updating, based on receiving information from the test device, the plurality of network addresses maintained by the device.
3. The method of claim 2 , where updating the plurality of network addresses includes:
removing information identifying a destination address of the first message from the plurality of network addresses.
4. The method of claim 1 , where determining that the first message is lost includes:
determining that the first message is lost based on not receiving a response from the test device within a predetermined time interval.
5. The method of claim 1 , further comprising:
configuring at least one test device, of a plurality of test devices, to send an acknowledgement when a command message directed to a particular test device, of the plurality of test devices, is received at another test device, of the plurality of test devices.
6. The method of claim 1 , where determining that the first message is lost includes:
receiving an acknowledgement from another test device connected within a same link aggregation group.
7. The method of claim 1 , where the plurality of second messages are sent multiple times.
8. The method of claim 1 , where each respective destination address is randomly chosen from a plurality of IP addresses.
9. The method of claim 1 , where the plurality of network addresses are stored by the device.
10. A non-transitory computer-readable medium storing instructions, the instructions comprising:
one or more instructions which, when executed by a processor of a device, cause the device to:
maintain a plurality of network addresses of nodes within a network;
determine that a first message transmitted to a test device is lost;
send, based on determining that the first message is lost, a plurality of second messages,
each second message of the plurality of second messages including a command sent in the first message and including a respective destination address of a plurality of destination addresses,
each respective destination address being different than a destination address of the first message, and
the plurality of network addresses including the plurality of destination addresses; and
receive, based on sending the plurality of second messages, an acknowledgement message from the test device,
the acknowledgement message being used to identify a particular destination address, associated with the test device, used for transmitting a third message to the test device.
11. The non-transitory computer-readable medium of claim 10 , where the instructions further include:
one or more instructions to update, based on receiving information from the test device, the plurality of network addresses maintained by the device.
12. The non-transitory computer-readable medium of claim 10 , where the one or more instructions to determine that the first message is lost include:
one or more instructions to determine that the first message is lost based on not receiving a response from the test device within a predetermined time interval.
13. The non-transitory computer-readable medium of claim 10 , where the plurality of second messages are sent multiple times.
14. The non-transitory computer-readable medium of claim 10 , where each respective destination address is randomly chosen from a plurality of IP addresses.
15. An apparatus comprising:
a memory to store instructions; and
one or more processors; configured to execute the instructions to:
maintain a plurality of network addresses of nodes within a network;
determine that a first message transmitted to a test device is lost;
send, based on determining that the first message is lost, a plurality of second messages,
each second message of the plurality of second messages including a command sent in the first message and including a respective destination address of a plurality of destination addresses,
each respective destination address being different than a destination address of the first message, and
the plurality of network addresses including the plurality of destination addresses; and
receive, based on sending the plurality of second messages, an acknowledgement message from the test device,
the acknowledgement message being used to identify a particular destination address, associated with the test device, used for transmitting a third message to the test device.
16. The apparatus of claim 15 , where the one or more processors are further configured to:
update, based on receiving information from the test device, the plurality of network addresses maintained by the apparatus.
17. The apparatus of claim 15 , where the one or more processors, when determining that the first message is lost, are configured to:
determine that the first message is lost based on not receiving a response from the test device within a predetermined time interval.
18. The apparatus of claim 15 , where the one or more processors are further configured to:
configure at least one test device, of a plurality of test devices, to send an acknowledgement when a command message directed to a particular test device, of the plurality of test devices, is received at another test device, of the plurality of test devices.
19. The apparatus of claim 15 , where the plurality of second messages are sent multiple times.
20. The apparatus of claim 15 , where each respective destination address is randomly chosen from a plurality of IP addresses.
