    Abstract: Some embodiments provide a network system. The network system includes a first set of host machines for hosting virtual machines that connect to each other through a logical network. The first set of host machines includes managed forwarding elements for forwarding data between the host machines. The network system includes a second set of host machines for hosting virtualized containers that operate as gateways for forwarding data between the virtual machines and an external network. At least one of the virtualized containers peers with at least one physical router in the external network in order to advertise addresses of the virtual machines to the physical router.

    Abstract: In order to enable dynamic scaling of network services at the edge, novel systems and methods are provided to enable addition of add new nodes or removal of existing nodes while retaining the affinity of the flows through the stateful services. The methods provide a cluster of network nodes that can be dynamically resized to handle and process network traffic that utilizes stateful network services. The existing traffic flows through the edge continue to function during and after the changes to membership of the cluster. All nodes in the cluster operate in active-active mode, i.e., they are receiving and processing traffic flows, thereby maximizing the utilization of the available processing power.

    Abstract: Some embodiments provide a method for handling failure at one of several peer centralized components of a logical router. At a first one of the peer centralized components of the logical router, the method detects that a second one of the peer centralized components has failed. In response to the detection, the method automatically identifies a network layer address of the failed second peer. The method assumes responsibility for data traffic to the failed peer by broadcasting a message on a logical switch that connects all of the peer centralized components and a distributed component of the logical router. The message instructs recipients to associate the identified network layer address with a data link layer address of the first peer centralized component.
