Overview

Mavenir's Virtual Cell Site Router (vCSR) is a cloud-native network function (CNF) designed to replace traditional physical cell site routers. By operating on common off-the-shelf (COTS) servers, vCSR reduces operational costs, minimizes power consumption, and enhances data throughput per watt. This transformation not only lowers total cost of ownership (TCO) but also frees up valuable rack space at cell sites, enabling the deployment of additional revenue-generating applications such as edge computing, content delivery networks (CDNs), and augmented reality (AR) services.

Features and Capabilities

• Full Integration and Energy Efficiency: Mavenir offers a unique solution by integrating vDU and vCSR CNFs on the same server, optimized for virtual RAN workloads. This integration reduces the number of devices to power and increases data throughput per watt.
• High Performance: The vCSR leverages a high-speed memory interface architecture, maximizing throughput and minimizing packet delay, ensuring efficient data handling.
• Automated Deployment and Swift Upgrades: With zero-touch provisioning, vCSR enables the deployment of thousands of cell sites without manual intervention. It also supports Continuous Integration and Continuous Delivery (CI/CD) architectures, allowing for rapid feature updates with minimal network downtime.
• Future-Proof Investment: Designed with a flexible software architecture, vCSR is hardware-agnostic and supports various network interface card options, ensuring adaptability to future technological advancements.
• Quality of Experience (QoE) for 5G Applications at Scale: vCSR supports end-to-end Quality of Service (QoS) slicing for applications, utilizing Segment Routing version 6 (SRv6) and programmable Segment ID (SID) binding to optimize network performance.
• Open and Programmable Solution: Built on open-source software with programmable interfaces (REST API & gNMI) and open configuration models (YANG), vCSR ensures compatibility with Cloud-native Network Functions (CNF) frameworks, facilitating seamless integration and network optimization.
