Abstract: Techniques are disclosed for deploying software upgrades to a mixed network of In-Service Software Upgrade (ISSU)-capable and ISSU-incapable network devices without interrupting network traffic serviced by the mixed network. In one example, a centralized controller for a network determines that first network devices of a plurality of network devices for the network are In-Service Software Upgrade (ISSU)-capable and second network devices of the plurality of network devices are not ISSU-capable. The centralized controller transmits messages instructing the first network devices to perform an ISSU operation. Further, the centralized controller transmits messages instructing each network device of the second network devices to transmit a message to peer network devices of the network device, the message indicating that the network device is not ISSU-capable. In response to receiving the message indicating that the network device is not ISSU-capable, the peer network devices redirect traffic to avoid the network device.

Abstract: Techniques are described in which a centralized controller constructs a service chain between a bare metal server (BMS) and a virtual execution element (e.g., virtual machine or container), or in some instances a remote BMS, across a plurality of networks. In some examples, the controller may construct a service chain between a BMS and a virtual execution element or remote BMS using Ethernet Virtual Private Network (EVPN)-Virtual Extensible Local Area Network (VXLAN) and Internet Protocol Virtual Private Networks (IP VPNs) such as BGP/Multiprotocol Label Switching (BGP/MPLS) IP VPNs.

Abstract: Virtual network controllers are described that automatically generate policies and configuration data for routing traffic through physical network function (PNF) service chains in a multi-tenant data center. An example network controller includes a memory and processing circuitry configured to: automatically generate, for one or more integrated routing and bridging (IRB) units of corresponding virtual network forwarding tables of a switch of a switch fabric of a data center network, configuration information that, when deployed, causes the IRB units to direct data traffic conforming to multiple communication protocols and flowing over a plurality of virtual networks between a first set of server devices and a second set of server devices positioned outside of the switch fabric (i) toward a service device logically positioned outside of the switch fabric and coupled to the switch, and (ii) back from the service device into the switch fabric via the switch.

Abstract: In general, techniques are described for defining and executing device-independent commands on a network having a plurality of network devices. In some examples, a controller includes a graphical user interface. The controller displays, via the graphical user interface, network devices that support a device-independent command selected from one or more device-independent commands, wherein each device-independent command performs one or more operations on supported network devices. The controller receives, via the graphical user interface, user input selecting two or more of the displayed network devices and performs the one or more operations of the selected device-independent command on the selected network devices. In some examples, performing includes executing tasks associated with each network device, wherein the tasks, when executed, perform the one or more operations on each respective network device.

Abstract: In general, techniques are described for managing, with a network controller for a computer network, the configuration of network devices within the computer network using one or more message buses. In some examples, a controller includes processing circuitry coupled to memory. The processing circuitry is configured to generate data for implementing a configuration change for a network device and store, to a configuration database, the data for implementing the configuration change for the network device. The processing circuitry is further configured to add, to a message queue of a message bus executed by one or more or more computing devices separate from the controller, an indication of the configuration change for the network device to cause the network device to obtain, from the configuration database, the data for implementing the configuration change for the network device.
