Allocating additional bandwidth to resources in a datacenter through deployment of dedicated gateways

Abstract

Some embodiments provide a method for deploying edge forwarding elements in a public or private software defined datacenter (SDDC). For an entity, the method deploys a default first edge forwarding element to process data message flows between machines of the entity in a first network of the SDDC and machines external to the first network of the SDDC. The method subsequently receives a request to allocate more bandwidth to a first set of the data message flows entering or exiting the first network of the SDDC. In response, the method deploys a second edge forwarding element to process the first set of data message flows of the entity in order to allocate more bandwidth to the first set of the data message flows, while continuing to process a second set of data message flows of the entity through the default first edge node. The method in some embodiments receives the request for more bandwidth by first receiving a request to create a traffic group and then receiving a list of network addresses that are associated with the traffic group. In some embodiments, the method receives the list of network addresses associated with the traffic group by receiving a prefix of network addresses and receiving a request to associate the prefix of network addresses with the traffic group. Based on this request, the method then creates an association between the traffic group and the received prefix of network addresses.
