    Abstract: In general, techniques are described for enhancing operations of virtual networks. In some examples, a network system includes a plurality of servers interconnected by a switch fabric comprising a plurality of switches interconnected to form a physical network. Each of the servers comprises an operating environment executing one or more virtual machines in communication via one or more virtual networks. The servers comprise a set of virtual routers configured to extend the virtual networks to the operating environments of the virtual machines. A virtual router of the set of virtual routers is configured to aggregate a plurality of inbound tunnel packets according to a same virtual network identifier in order to generate an aggregate tunnel packet. The virtual router is further configured to route the aggregate tunnel packet to a host associated with a virtual network identified by the same virtual network identifier.

    Abstract: In general, techniques are described for performing a controlled non-stop software upgrade (NSSU) of a network device. In some examples, a method includes receiving, by a first network device included in a virtual network device, a non-stop software upgrade (NSSU) request. The first network device is communicatively coupled to each of a computing device and a second network device. The method includes, in response to receiving the NSSU request, forwarding to the second network device, network packets that are received at the first network device and destined to the computing device. The method also includes sending a message to the computing device that instructs the computing device to stop sending network packets to the first network device. The method includes updating one or more software components within the first network device, after sending the message to the computing device and based at least in part on the NSSU request.

    Abstract: In general, techniques are described for enhancing operations of virtual networks. In some examples, a network system includes a server that executes a virtual router configured to receive, from a switch fabric, a tunnel packet for a virtual network of the virtual networks, wherein the tunnel packet comprises an outer header and an inner packet that defines a packet flow. The virtual router is also configured to determine, based at least on the outer header, that the packet is associated with a virtual network of the one or more virtual networks, determine a packet flow defined by the inner packet does not match any flow table entry of a flow table that identifies active flows only for virtual network and, in response, add a flow table entry for a reverse packet flow of the packet flow to the flow table.
