Bypassing failed hub devices in hub-and-spoke telecommunication networks

A data processing method comprising:

• using a first hub device, establishing one or more secure connections with one or more spoke devices logically arranged as spokes with respect to a data processing system;
• using the first hub device, generating and sending via a high-speed link a hub probe to a second hub device wherein the hub probe is configured to determine whether the second hub device is responsive;
• using the first hub device, in response to determining that the second hub device is nonresponsive, transmitting, to the one or more spoke devices over the one or more secure connections, a first communication indicating that the second hub device is nonresponsive;
• using a spoke device, receiving the first communication indicating that the second hub device is nonresponsive;
• using the spoke device, determining whether the spoke device has established a secure connection with the second hub device;
• using the spoke device, in response to determining that the spoke device has established the secure connection with the second hub device, selecting a third hub device, establishing a secure connection with the third hub device, and communicating with the third hub device;
• wherein the method is performed using one or more computing devices.

A data processing system comprising:

• a first hub device comprising:
• one or more non-transitory computer-readable hub storage media storing sequences of instructions which, when executed, cause performance of:
• establishing one or more secure connections with one or more spoke devices logically arranged as spokes with respect to the data processing system;
• generating and sending via a high-speed link a hub probe to a second hub device wherein the hub probe is configured to determine whether the second hub device is responsive;
• in response to determining that the second hub device is nonresponsive, transmitting, to the one or more spoke devices over the one or more secure connections, a first communication indicating that the second hub device is nonresponsive.
