UNLOCKING INNOVATION AND VALUE IN THE RADIO ACCESS NETWORK

whitePaper | January 15, 2020

Synchronization in carrier networks has been in use forever, but because of its elevated role in 5G, it is now getting more attention. Mobile cellular networks must be synchronized so that towers (base stations) with overlapping coverage do not interfere with each other causing dropped calls or service degradation. The NodeBs used in Third Generation (3G) cellular communications rely on satellite communications for synchronization, as do the Baseband Units (BBUs) used in Fourth Generation (4G) cellular communications.

At the end of 2019, Heavy Reading surveyed 77 communications service providers (CSPs) on their plans for virtualization overall, and virtualized radio access networks (vRANs) specifically. A lot has happened since then that could throw the carriers off course – like data centers and central offices going zero-touch and lights-out virtually overnight. Heavy Reading checked in with the carriers in Q2 2021 to see how their plans have changed. This report highlights the results of our 2021 survey, comparing and contrasting them with the results from our 2019 survey.

Switch stacking is a technology that connects multiple physical switches into a single logical switch. Network administrators can add or remove switches to increase or decrease port count without getting a multi-card chassis switch and dealing with the configuration of multiple switches. The network can evolve over a period with a pay as you grow model and therefore benefit from both the switch vendors and their customers.

Enterprise and residential market dynamics, 5G, and the cloud are driving new applications—and creating new revenue opportunities for Communications Service Providers (CSPs). But these emerging use cases are also creating challenges: new traffic patterns, the move to virtualized and distributed applications, and the need for higher bandwidth and lower latency connectivity to end-users. IP/Optical convergence can play a key role in helping CSPs address these, but where does the path to architecture evolution begin? For every CSP, the journey is unique. With Ciena’s solutions, CSPs can start—and build—from their existing networks to evolve to a more streamlined, programmatic infrastructure that can serve as the foundation for innovation in the distributed services and content era.

Organizations today require immediate and uninterrupted access to critical network and cloud-based resources in order to support the swift pace of digital business transformation. Spurred by the boom in remote work and the ongoing migration to cloud-based applications and services, consumption patterns are transforming traditional private and public networks into a single network of many end-users and devices scattered across the organization’s footprint. As a result, there are growing security concerns with this rapidly changing environment many traditional security solutions no longer provide the protection needed along with the flexibility to support businesses anywhere, anytime, via any device

Increasingly, broadband service providers (BSPs) are upgrading to next-generation XGS-PON fiber networks. Why? These advanced networks are necessary to support the new era we live in—one of high-bandwidth services and rich subscriber experiences backed by popular cloud-based applications and services. Next-generation XGS-PON fiber networks can deliver those high-speed 10G offerings and enable broadband businesses to provide popular subscriber services to both homes and businesses. In this world of increased demand for more bandwidth, BSPs also need networks that enable service provisioning in minutes—not days or hours. Networks must be seamlessly optimized and scaled to meet changing subscriber demands.
