Abstract
Systems and methods are provided to enable packets of network traffic to be hashed to available network gateway. Each packet can include a route table with a pool of network gateways as a next-hop of the packet. A network device may intercept the packet and hash the packet to a network gateway of the pool of network gateways. The network gateway can correspond to a stateful network router and the stateful network router can transmit the packet to a network appliance. The network device can monitor and perform health-checks on the network gateways, the stateful network routers, and the network appliances. The network device can remove components that are no longer healthy or available and can add components that subsequently become healthy.
