    Abstract: In general, techniques are described for enhancing operations of virtual networks. In some examples, a network system includes a network interface card of a server configured to receive a tunnel packet associated with a virtual network. The tunnel packet comprises an outer header associated with the physical network, the outer header encapsulating an inner packet comprising an inner header associated with the virtual network and a payload. A first processing core of the server is configured to perform, based at least on one of the outer header and inner header of the tunnel packet, a first packet steering operation to identify the second processing core. The second processing core is configured to forward the inner packet to a virtual machine of the virtual machines.

    Abstract: In some embodiments, an apparatus includes a first controller configured to be operatively coupled within a network having a set of network nodes, a forwarding gateway and a configuration entity. The first controller is configured to manage session state and node state associated with the set of network nodes independent of the forwarding gateway. The first controller is configured to fail over to a second controller when the first controller fails, without the forwarding gateway failing over and without the configuration entity failing over.

    Abstract: Techniques are disclosed for performing an In-Service Software Upgrade (“ISSU”) of a first packet forwarding component (PFC) of a virtual router configured to forward traffic flows for a plurality of session instances within a cloud-based data center. The techniques described herein may retain flow state information throughout the ISSU process without interrupting network traffic flow. In one example, a processor of a plurality of compute nodes within the data center receives a request to perform an ISSU of the first PFC. The processor spawns a second virtual routing agent and a second PFC. The second virtual routing agent synchronizes flow state information with a first virtual routing agent for the virtual router. After synchronizing the flow state information, the virtual router switches from forwarding traffic flows by the first PFC to forwarding traffic flows by the second PFC. The ISSU process deactivates the first virtual router and the first PFC.
