Abstract
Some embodiments provide an ARP-offload service node for several managed hardware forwarding elements (MHFEs) in a datacenter in order to offload ARP query processing by the MHFEs. The MHFEs are managed elements because one or more network controllers (e.g., one or more management servers) send configuration data to the MHFEs to configure their operations. In some of these embodiments, the network controllers configure the MHFEs to create logical forwarding elements (e.g., logical switches, logical routers, etc.) each of which can span two or more managed forwarding elements.
