Abstract: In general, this disclosure describes techniques for provisioning virtual private network (VPN) services for cloud native routers using a multi-stage process. In an example, a method comprises deploying, in a first computing device, using a layer 2 bridge domain that includes the first computing device, a containerized routing protocol process; deploying, in the first computing device, using the layer 2 bridge domain, a containerized application; configuring, in the containerized routing protocol process executing on the first computing device, a virtual private network (VPN); and exchanging, by the containerized routing protocol process executing on the first computing device, routing protocol messages with another router to provide virtual connectivity between the containerized application and another application that is external to the first computing device.

Abstract: In general, techniques are described for deploying virtualized cell site routers (vCSRs) capable of layer 2 (L2) forwarding to cell site servers to support management and orchestration of functional units for mobile networks executing on the cell site servers. In an example, a method comprises receiving, at a forwarding plane of a virtualized cell site router (vCSR) of a first Distributed Unit (DU) of a plurality of DU servers of a cell site for a 5G radio access network, the vCSR having a containerized routing protocol process and a forwarding plane configured to perform Layer 2 (L2) switching, L2 packets on a second interface for a second physical link connecting the first DU server to an L2 switch; and switching, by the forwarding plane of the vCSR of the first DU, the L2 packets on a first interface for a first physical link connecting the first DU server to a second DU server of the plurality of DU servers.

Abstract: An example method includes determining, by a network controller, based on a high-level data model, vendor-agnostic device information for a first network device, translating the vendor-agnostic device information into vendor-specific device information, sending, to the first network device, first configuration information included in the vendor-specific device information to cause the first network device to switch into a maintenance mode and enable diversion of network traffic from the first network device to a second network device, responsive to verifying that the first network device has diverted the traffic, initiating maintenance procedures on the first network device while the first network device is in the maintenance mode, and sending, to the first network device, second configuration information included in the vendor-specific device information to cause the first network device to switch out of the maintenance mode and enable reversion of network traffic from the second device to the first network device.

Abstract: In general, this disclosure describes techniques for providing a hybrid data plane that can include a kernel-based data plane and a Data Plane Development Kit (DPDK)-based data plane. An example system includes a DPDK-based virtual router configured to send and receive packets via a physical network interface, and a kernel network stack configured to perform tunneling processing for packets destined to a containerized application and received by the DPDK-based virtual router via the physical interface.

Abstract: Example techniques and computing devices are disclosed. An example computing device includes a first non-uniform memory access (NUMA) node and a second NUMA nod. The first NUMA node includes a first network interface card, a first virtual router for one or more virtual networks, the first virtual router comprising first processing circuitry and configured with a first virtual host interface having a first Internet Protocol (IP) address, and a first workload executing on the first NUMA node. The second NUMA node includes a second network interface card, a second virtual router for the one or more virtual networks, the second virtual router comprising second processing circuitry and configured with a second virtual host interface having a second IP address, and a second workload executing on the second NUMA node.

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.
