Abstract: In general, this disclosure describes techniques for a containerized router operating within a cloud native orchestration framework. In an example, a computing device comprises a containerized routing protocol process executing on processing circuitry of the computing device and configured to receive routing information; a containerized set of workloads; a data plane development kit (DPDK)-based virtual router executing on the processing circuitry and configured to forward traffic to and from the workloads based on the routing information from the containerized routing protocol; and a virtual router agent for the virtual router, the virtual router agent executing on the processing circuitry and configured to expose a generic data plane interface.

Abstract: In an example, a method includes processing, by an application programming interface (API) server implemented by a configuration node of a network controller for a software-defined networking (SDN) architecture system, requests for operations on native resources of a container orchestration system; processing, by a custom API server implemented by the configuration node, requests for operations on custom resources for SDN architecture configuration, wherein each of the custom resources for SDN architecture configuration corresponds to a type of configuration object in the SDN architecture system; detecting, by a control node of the network controller, an event on an instance of a first custom resource of the custom resources; and by the control node, in response to detecting the event on the instance of the first custom resource, obtaining configuration data for the instance of the first custom resource and configuring a corresponding instance of a configuration object in the SDN architecture.

Abstract: Techniques are described in which a centralized controller, such as a software defined networking (SDN) controller, constructs a service chain that includes a physical network function (PNF) between a bare metal server (BMS) and a virtual execution element (e.g., virtual machine or container), or in some instances a remote BMS, or vice-versa. In accordance with the techniques disclosed herein, the controller may construct an inter-network service chain that includes PNFs, or a combination of PNFs and virtualized network functions (VNFs). The controller may construct an inter-network service chain to steer traffic between a BMS and a virtual execution element or remote BMS through an inter-network service chain using Virtual Extensible Local Area Network (VXLAN) as an underlying transport technology through the service chain.

Abstract: In general, this disclosure describes techniques for a containerized router operating within a cloud native orchestration framework. In an example, a virtualized cell site router comprises a computing device configured with a containerized router, the computing device comprising: a containerized virtual router configured to execute on the processing circuitry and configured to implement a data plane for the containerized router; a containerized routing protocol process configured to execute on the processing circuitry and configured to implement a control plane for the containerized router; and a pod comprising a containerized distributed unit, wherein the containerized routing protocol process is configured to advertise routing information comprising reachability information for the containerized distributed unit.

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.
