Abstract
A method for cooperative active-standby failover between service routers based on health of services configured on the service routers is presented. In an embodiment, a method comprises determining, by a first service router ('SR') of a SR cluster, a plurality of aggregate score values for a plurality of SRs of the SR clusters. The SR cluster comprises the first SR which is active, and a second SR. An aggregate score value, of the plurality of aggregate score values, indicates health of one or more services configured on a SR. The method further comprises determining, based on the plurality of aggregate score values, whether the first SR, of the SR cluster, is healthier than the second SR. In response to determining that the first SR is healthier than the second SR, the first SR continues to operate in the active mode; otherwise, the first SR switches to a standby mode.
