Method of cooperative active-standby failover between logical routers based on health of attached services

One or more non-transitory computer-readable storage media storing one or more computer instructions which, when executed by one or more processors, cause the one or more processors to perform:

• receiving, by a first service router (“SR”) of a SR cluster, a plurality of aggregate score values for a plurality of SRs in the SR clusters;
• wherein the SR cluster comprises the first SR and a second SR;
• wherein the first SR is operating in an active mode;
• wherein an aggregate score value, of the plurality of aggregate score values, indicates health status of a plurality of services configured on a SR;
• determining, based on the plurality of aggregate score values, whether the first SR, of the SR cluster, is healthier than the second SR;
• and
• in response to determining that the first SR is healthier than the second SR, causing the first SR to continue to operate in the active mode.

A system comprising:

• one or more processors;
• one or more memory units;
• and
• one or more non-transitory computer-readable storage media storing one or more computer instructions which, when executed by the one or more processors, cause the one or more processors to perform:
• receiving, by a first service router (“SR”) of a SR cluster, a plurality of aggregate score values for a plurality of SRs in the SR clusters;
• wherein the SR cluster comprises the first SR and a second SR;
• wherein the first SR is operating in an active mode;
• wherein an aggregate score value, of the plurality of aggregate score values, indicates health status of a plurality of services configured on a SR;
• determining, based on the plurality of aggregate score values, whether the first SR, of the SR cluster, is healthier than the second SR;
• and
• in response to determining that the first SR is healthier than the second SR, causing the first SR to continue to operate in the active mode.
