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: In general, techniques are described for deploying virtualized cell site routers (vCSRs). 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 identifying, based on a received indication, at least a first network device that is to be placed in the maintenance mode, determining device information for the first network device, sending, to the first network device, first configuration information included in the 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 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.
