5G promises transformational economics for service providers and new experiences for their customers. But 5G New Radio technologies alone won’t allow operators to realize the full potential of 5G.
5G is the sum of many building blocks that span radio access, transport, and core networks. 5G also relies on automation for new levels of orchestration, security, and service assurance.
Delivering the differentiated customer experiences that allow operators to maximize 5G value requires integrating these components end-to-end. That’s why Juniper believes it takes an ecosystem to build a 5G network.
Open RAN is a shift in mobile network architecture from a closed vendor environment to an open, intelligent, and programmable one. Open RAN enables vendors, service providers, and developers to deploy innovative services as radio access network (RAN) applications that take advantage of artificial intelligence and machine learning. Juniper has a history of leading cloud and networking shifts that include disaggregation, virtualization, containerization, and openness in our WAN, data center, and AI-driven enterprise solutions. A similar change is now happening in the RAN.
Juniper offers O-RAN-compliant products and solutions across the entire network.
Juniper’s open and interoperable RAN Intelligent Controller (RIC) platform facilitates integration among partners in the O-RAN ecosystem. It onboards both Juniper and third-party rApps/xApps to enable new business models, personalize service experiences, and help optimize CapEx and OpEx.
Juniper Service Management and Orchestration (SMO) delivers end-to-end network slicing with support for prescribed SLAs across RAN, transport, and core networks. The solution supports multicloud, multidomain, and multitenant deployment models, meets O-RAN SMO requirements, and supports O-RAN interfaces and 3GPP Network Slicing Management Functions.
O-RAN fronthaul connections require very low end-to-end latency and jitter. Juniper ACX 7100 routers support IEEE 802.1 Time-Sensitive Networking Profile A for prioritized enhanced Common Public Radio Interface (eCPRI) or Precision Time Protocol (PTP) packets, Class D timing, and transport features such as segment routing and Ethernet VPN (EVPN).
The Open RAN ecosystem requires industry collaboration. Juniper, Rakuten, and Intel are offering integrated routing and Open RAN in a single platform that delivers cost and operational benefits. Juniper and Intel are also collaborating on RIC apps to improve customer experience, maximize ROI, and drive rapid ecosystem innovation.
Juniper is an active proponent of Open RAN in several industry and standards organizations. We contribute to six of the 10 working groups in the O-RAN Alliance. Juniper also chairs the Network Slicing Task Group, co-chairs the Use Case Task Group, and serves as editor and contributor to several specification documents.
In the cloud era, the highest quality experiences are provided through disaggregated solutions with open networking.
Open Automation
Automation requires the underlying software to be open and programmable. Juniper’s open networking solutions provide rich telemetry and are highly programmable through standard APIs. They enable full and open automation using Juniper’s tools or third-party offerings.
Flexible Operations
Disaggregation enables deployment flexibility by allowing cloud providers to mix and match hardware under a single operating system. Juniper’s industry-leading routing stack streamlines operational efficiency across the infrastructure, whether on Junos Evolved, SONiC, whitebox, or a Linux server.
Reliable Infrastructure
By default, a microservices architecture is designed to provide high reliability. It allows fault isolation between components and the ability to restart them with the last state if problems occur. A microservices-based architecture also enables hitless upgrades for individual components without impacting services.
Junos Evolved: Cloud-optimized network OS and microservices architecture delivering resiliency, feature velocity, and programmability.
Junos Evolved Network OS extends traditional disaggregation by creating a flexible consumption model for network operations. A cloud-optimized, microservices-based operating system with a deployment-hardened routing stack, Junos Evolved reduces the time and effort you need to plan, deploy, and operate your cloud infrastructure.Junos Evolved improves openness, scalability, reliability, and simplicity on Juniper and whitebox switches and routers. Juniper’s fully featured routing stack can be implemented on any Linux platform, acting as a forwarding plane, including servers and whitebox switches and routers.
Sonic: Juniper SONiC implementations enable high-performance, end-to-end deployments at scale, including spine and WAN core.
Juniper’s support for SONiC is another step on our path to fuel the disaggregation movement. The disaggregated SONiC operating system offers cloud providers the ability to implement best-of-breed technology with a single OS for reduced operational costs, automated resiliency, and greater flexibility.
cRPD: Enables cloud providers to leverage cloud economics with containerized, deployment-hardened routing functions.
Additionally, cloud providers can take advantage of our routing stack by using Junos containerized routing protocol daemon (cRPD), which is agnostic toward the underlying network operating system, whether Linux or SONiC.
At Juniper Networks, disaggregation is both the strategic thrust behind a lot of our efforts and an engineering principle that underscores virtually every architectural decision we make. It is at once an explicit part of our roadmap and an implicit directive to our engineering teams.
And, as a core part of what we build and how we build it, disaggregation plays a key role in our broader corporate strategies around cloud, multicloud, and distributed and edge cloud.
The development of Junos has been a 20+ year journey for Juniper, and we're continuing to iterate and modernize how we build systems.This demonstration shows the implementation of a 3rd party application on Junos Evolved, specifically running OpenR in a container on a Junos Evolved system.
