Abstract
Some embodiments provide a method for a gateway datapath that executes on a gateway device to implement logical routers for a set of logical networks and process traffic between the logical networks and an external network. The method receives a data message at the gateway device. To process the data message, the method executes a set of processing stages that includes a processing stage for a particular logical router. As part of the processing stage for the particular logical router, the method (i) uses an access control list (ACL) table to determine whether the data message is subject to rate limiting controls defined for the particular logical router and (ii) only when the data message is subject to rate limiting controls, determines whether to allow the data message according to a rate limiting mechanism for the particular logical router.
