Migrating Fixed Access to 5G Core

whitePaper | July 8, 2021

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.

Layer 1 transport services are a highly profitable offering that service providers can sell to enterprises. These services, which include ethernet, fiber channel, and legacy SDH/SONET, provide connection to data centers and other corporate locations. However, it has always been a challenge to provision these services fast enough, due to the rigid, low-cost nature of optical access networks. This paper highlights how an innovative and economical access-to-core Optical Transport Networking (OTN) switching solution can enable service providers to provision these lucrative services rapidly, speeding up time to revenues, maintaining customer satisfaction, while also guaranteeing service availability.

Traditional methods of building wide area networks (WANs) have always had limitations, but fell even further behind with the adoption of the cloud and remote work. Software-defined WANs (SD-WANs) have simplified many aspects of WAN management, but are unable to fully break away from the hub-and-spoke model due to security requirements. Modern WAN-as-a-Service offerings address these shortcomings while providing organizations cost savings and improving network performance.

For each VPN tunnel, both AH and ESP tunnel sessions are installed on Services Processing Units (SPUs) and the control plane. Tunnel sessions are updated with the 7 protocol on is completed. For SRX5400, SRX5600, and SRX5800 devices, tunnel sessions on anchor SPUs are updated with the protocol while non-anchor SPUs retain ESP and AH tunnel sessions. ESP and AH tunnel sessions are displayed in the outputs.

The landscape of telecommunications options available to support utilities’ Operational Technology (OT) solutions is rapidly evolving - at a pace compared only by the changing needs of the OT requirements themselves. As utilities replace first generation Advanced Metering Infrastructure (AMI) solutions with current more feature-rich systems and expand the reach of traditional Distribution Automation (DA), Field Mobility (FM) and other existing solutions; new options are required for device connectivity and backhaul. The potential explosion of ubiquitous Internet of Things (IoT) devices will further change the utilities’ needs.
