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 processing circuity; a containerized set of workloads; a containerized routing protocol process configured to execute on the processing circuitry and configured to receive routing information; a kernel network stack executing on the processing circuitry and configured to forward packets based on first routing information from the containerized routing protocol process; and a data plane development kit (DPDK)-based virtual router executing on processing circuitry and configured to forward traffic to and from the workloads based on second routing information from the containerized routing protocol process.

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: Techniques are disclosed for a computing system comprising processing circuitry having access to a storage device, the processing circuitry configured to encode, by a network controller executing in a software defined network (SDN), one or more attributes with information identifying a network service, wherein the one or more attributes conform to a routing protocol. The processing circuitry is also configured to generate, by the network controller, an advertisement in a first network cluster executing within a container orchestration platform of the SDN, wherein the advertisement conforms to the routing protocol and includes the one or more attributes. The processing circuitry is also configured to broadcast, by the network controller and to a second network cluster executing within the container orchestration platform of the SDN, the advertisement in accordance with the routing protocol.
