Open Interface Orchestration: The New Beat of Telco Network Cloud Platforms The primary objective of cloudification in telecom is to shift from hardware-centric network models to software- and data-driven architectures. This evolution allows telcos to capitalize on the benefits of softwarization and cloud computing – primarily cost reduction, improved service delivery, and enhanced ability to launch and scale new services swiftly. ◼ Reality Check - Diversified Cloud Platforms and VNFs/CNFs for Different Network Domains The current landscape of cloudification, however, presents its set of challenges. The telco environment is characterized by a range of diversified vendor-driven cloud platforms and VNFs/CNFs tailored to different network domains. This diversity leads to complexity in management and integration. Each network domain, from RAN to the core, demands specific performance metrics and operational capabilities. For example, RAN function workloads are very time-sensitive. RAN processing such as signal encoding, decoding, and radio frequency scheduling must occur in real-time or near-real-time to maintain the quality of service. Moreover, telcos often grapple with fragmented cloud implementation because of legacy systems, long-standing vendor relationships, and the specific technical requirements of telecom services. Vertical stacks from individual vendors may offer optimized performance and easier management for the vendor's services, leading to a situation where different stacks are used for different purposes. Transitioning to a horizontal stack requires significant integration work and can be challenging when ensuring the same level of reliability and performance across various services. ◼ Open Interface-Driven Multi-Vendor Cloud Platform Orchestration To tackle the complexity and fragmentation in telco network cloudification, the open RAN industry is moving towards open interface-driven multi-vendor cloud platform orchestration. This approach is exemplified by the O2 interface of the O-Cloud. O-Cloud refers to a specific part of the O-RAN ALLIANCE's architecture that focuses on the cloud infrastructure needed to support virtualized RAN functions in compliance with O-RAN standards. Open interface principles like O2 facilitate a multi-vendor environment where different network elements, irrespective of the provider, can communicate effectively and function cohesively. By adhering to common interface standards, telcos can mix and match components from various cloud platform vendors, encouraging competition, fostering innovation, and avoiding vendor lock-in. The open interface-based cloudification principle is a practical solution that provides a clear path for service providers to navigate the complexities of modern network cloud platforms, integrating disparate cloud resources into a unified, manageable system. #NetworkCloud #TelcoNetwork #SDN #NFV #OpenSourceCloud #k8s #Nephio #OpenInterfaceCloud #OCloud #O2interface

Open RAN breaks the Generational “G” cycle for mobile networks – mobile operators are deploying 6G architectures today. Open RAN is transforming traditional, monolithic radio access networks into more flexible and open architectures supporting generations of cellular technology 4G, 5G and including 6G in the future. Open RAN today, is a 6G network architecture that is based on a combination of virtualized and disaggregated components. It is designed to provide more flexibility and interoperability in the radio access network by allowing operators to mix and match components from different vendors. It does this by decoupling the hardware and software components of the network, allowing operators to select and deploy best-of-breed solutions from different vendors. While Open RAN is currently being deployed in 4G and 5G networks, it is also expected to play a role in future generations of cellular technology, including the anticipated 6G networks. Open RAN's open and flexible architecture is well-suited to support the evolving requirements and complexities of future wireless networks. In deploying an Open and Interoperable network today, operators are also free to deploy features, such as spectrum capacity upgrades, power saving, handoff improvements and functionality that differentiate their individual competitive offering whilst still taking advantage of the global 3GPP handset specifications. Open RAN offers the potential to enhance individual network performance, increase competition, and accelerate innovation in the telecommunications industry that support the next generation features and functionality – 6G features are a software upgrade. #OpenRAN #6G #telecommunications #innovation

In this article about Open RAN adoption, Mike Dano Mike Dano does a fine job explaining the state of global adoption, and also the political motivators behind the PR and the rates of adoption. Is Open RAN playing out the way it was hoped: as a set of lego where you can buy a piece from any vendor, and snap it into pieces from other vendors to build a working telecom network? Well, no. As probably should have been expected, it's easier to work with a single vendor, even if equipment is interoperable *on paper*. But most of all, we like Dano's conclusion, which sums it all up quite well using the lego metaphor: "...if you shop through enough yard sales, you could probably collect enough Lego pieces to build something that looks a lot like the Millenium Falcon. Or you could buy the Millenium Falcon set from Lego for $850.  Either way, you still have to actually assemble it." It's a bit early, but May the Fourth be with you, Mike. https://lnkd.in/g8YkMfi5

Multi-Vendor O-RAN RIC xApps/rApps Coordination O-RAN ALLIANCE O-RAN architecture includes the RAN Intelligent Controller (RIC). RIC comes in two flavors: the Non-Real-Time (>1sec) RIC rApps and the Near-Real-Time (10ms<Near RT<1sec) RIC xApps. These applications interact via the O-RAN A1, E2, O1 interfaces. ◼ Importance of Multi-Vendor xApps/rApps Coordination in RIC Operations A core objective of the O-RAN initiative is to facilitate a competitive, multi-vendor ecosystem. With standardized interfaces like O1, O2, A1, E2, xApps and rApps from different vendors can coexist on the same RIC platform, providing Telcos with the flexibility to select the best applications for their unique needs. However, effective coordination between multi-vendor xApps and rApps is vital for smooth RIC operations. These applications work at different layers and speeds to optimize network performance. Without clear coordination, they risk conflicting or redundant actions, ultimately degrading network performance. ◼ Coordination Example: A practical illustration of the importance of coordination involves an energy-saving rApp from Vendor A and a traffic-steering xApp from Vendor B. - Energy-Saving rApp: This application aims to conserve power by intelligently switching off unused or underused cells while maintaining adequate coverage. It monitors long-term traffic patterns to predict low-demand periods. - Traffic-Steering xApp: This application balances traffic loads between different cells and layers in near real-time. It ensures users are always connected to the best-performing cell, reducing congestion and improving user experience. ◼ Coordination in Practice - Initial Setup: Both applications initialize their data collection and configuration processes. The traffic-steering xApp begins adjusting cell traffic loads based on near-real-time metrics, while the energy-saving rApp assesses long-term usage patterns. - Monitoring: The energy-saving rApp notices a consistent low-traffic period and plans to deactivate a specific capacity cell for energy savings. Meanwhile, the traffic-steering xApp ensures that active cells can absorb the additional load. - Notification and Adjustment: The energy-saving rApp informs the traffic-steering xApp through the RIC framework of its intention to deactivate the capacity cell. The traffic-steering xApp then directs the remaining UEs connected to this cell to alternative coverage cells before deactivation. - Action Execution: Once the load balancing is complete and the capacity cell is safely offloaded, the energy-saving rApp executes the shutdown, ensuring no UE is impacted. This was a joint demo by Juniper Networks, AirHop Communications, Rimedo Labs, Keysight Technologies, and Vodafone at the RIC Forum hosted by NITA in March, showing energy savings of up to 25% at the capacity layer. #ORAN #OpenRAN #xApps #rApps #RIC #EnergySaving #TrafficSteering #RICAppsCoordination #RICForum
