Abstract

Systems, methods, and devices are disclosed for re-routing network traffic directed to a pod device. Traffic is routed from an ingress device towards a first node in communication with multiple pods. In response to the detection of a failure event associated with the first pod, a network device address of the first pod is removed from a routing table. If a packet is received from the ingress device that is destined for a service, the routing table is used to look up a pod for handling a service request associated with the service. A network device address of a second pod is determined based on not finding the network device address of the first pod in the routing table. The packet is then forwarded to the second pod using the second device address before the ingress device knows that the first pod has failed.
