Cloud-Native Routers: Transforming the Economics of Distributed Networks

Simplifying Operability & Manageability with Cloud-Native Routing.

The Juniper Cloud-Native Router (JCNR) is a performant, container-based software solution that combines Juniper's proven routing technology.This includes the Junos OS containerized routing protocol daemon (cPRD) and the Contrail vRouter DPDK forwarding plane for x86 processors. It integrates seamlessly with the Kubernetes Container Network Interface (CNI) framework, enhancing its efficiency and performance.

The JCNR vRouter is a high-performance datapath component. It is an alternative to the Linux bridge or the Open vSwitch (OVS) module in the Linux kernel. It runs as a user-space process. The vRouter functionality is implemented in two pods, one for the vrouter-agent and the vrouter-telemetry-exporter,and the other for the vrouter-agent-dpdk. This split gives you the flexibility to tailor CPU resources to
the different vRouter components as needed.

The Cloud-Native Router takes full advantage of container economics and the operational efficiencies inherent in cloud-native environments. Based on the same Junos operating system routing technology, these hybrid networks provide a single end-to-end experience.The software based router complements Juniper’s physical routers with advanced networking features for cloud-native environments where space, power, and cooling are limited. Based on the same Junos OS routing technology, hybrid physical and virtual networks provide a single experience end to end.

The challenges of 5G deployment have pushed the industry to rethink networks. To meet the scale, distribution, and cost requirements of 5G rollout and expansion, service providers are integrating cloud-native infrastructure in D-RAN sites where space, power, and cooling are limited.

Adding 5G requires significant network expansion by service providers as the distance requirements between radio tower and users are much shorter than previous-gen technologies. To reduce both CapEx and OpEx for the expansion, they are disaggregating the radio access network (RAN) and turning to hyperscalers for some of their 5G RAN data center needs. These changes require the use of a hybrid routing infrastructure with both physical and cloud-native routers. The Juniper Cloud-Native Router gives service providers the flexibility required to roll out 5G.

Use Cases

RAN-

A 5G RAN environment typically consists of a mix of C-RAN and D-RAN sites. The C-RAN sites use bandwidth-intensive fronthaul connections and will continue to take advantage of physical routers. Some larger D-RAN sites may also use physical routers. However, providers will often take advantage of smaller D-RAN sites, that can easily number in the tens of thousands, to access user populations. Juniper Cloud-Native Router is designed to work in the constraints of a D-RAN. It is integrated with the distributed unit (DU) and installable on an existing 1 U server.

Telco virtual private cloud (VPC)-

As infrastructure expands to support 5G, more radio sites are required, and data centers need to be expanded. One option is to build out data centers in hyperscaler public cloud environments; however, the current cloud-native routing within these environments does not support the full routing functionality required for telco VPCs such as MPLS, quality of service (QoS), L3 VPN, IP address management, and others. The Juniper Cloud-Native Router integrates directly into the cloud as a containerized network function (CNF), managed as a cloud-native Kubernetes component, while providing advanced routing capabilities.

Features and Benefits

· Advanced Service Integration-Easily integrate cloud-native, advanced Junos OS networking services into cloud applications, accelerating development and increasing reliability.

· Fast Packet Processing-The Contrail vRouter DPDK forwarding plane enables high packet throughput for enhanced router performance.

· Light Footprint-Deployable anywhere compute resources are available, the router takes advantage of fragmented resources, making it ideal for cloud-native deployments.

· Deployment Simplicity-The Cloud-Native Router works seamlessly in NetOps 2.0 environments and can also be managed using traditional network operations methods.
