CERN-GPN2

Overview

CERN-GPN2, which stands for CERN General Purpose Network 2, is a critical component of the networking infrastructure at the European Organization for Nuclear Research (CERN). It is a high-performance, high-availability network service designed to meet the stringent demands of modern scientific research, particularly in fields like particle physics that generate and process massive amounts of data. GPN2 provides the underlying connectivity that enables researchers, computing centers, and collaborating institutions worldwide to access CERN's resources, share data, and participate in distributed computing projects. The service is built upon robust, state-of-the-art networking technologies to ensure reliability, scalability, and speed.

Key Features

• High Bandwidth and Throughput: GPN2 is engineered to deliver substantial network bandwidth, capable of supporting terabytes of data transfer daily. This is crucial for experiments like the Large Hadron Collider (LHC) which produce petabytes of data.
• Global Reach and Connectivity: It connects CERN to a vast network of research institutions and data centers across the globe through dedicated links and peering arrangements with other high-performance networks.
• Reliability and Availability: Designed with redundancy and fault tolerance in mind, GPN2 aims for high availability to ensure continuous operation of critical research services.
• Scalability: The infrastructure is designed to scale to accommodate growing data volumes and increasing numbers of connected users and institutions.
• Advanced Network Services: Beyond basic connectivity, GPN2 may offer specialized network services tailored for scientific applications, such as Quality of Service (QoS) guarantees or optimized routing.
• Security: Robust security measures are implemented to protect the network infrastructure and the data traversing it.

Typical Use Cases

• Data Transfer: Facilitating the transfer of massive datasets from CERN to distributed computing centers for analysis and storage.
• Remote Access: Enabling researchers at collaborating institutions to remotely access computing resources and data archives at CERN.
• Distributed Computing: Supporting grid computing and cloud computing initiatives where computational tasks are distributed across multiple sites.
• Collaboration: Enhancing collaboration among scientists by providing seamless and high-speed communication channels.
• Experiment Operations: Ensuring reliable network connectivity for real-time data acquisition and control systems for experiments.

Pricing & Hosting Model

CERN-GPN2 is an internal service provided by CERN to its users and affiliated research organizations. As such, it does not operate on a traditional commercial pricing model. The costs associated with building, maintaining, and operating GPN2 are borne by CERN, funded through its member states and specific project budgets. Access to GPN2 is typically granted based on research needs and collaboration agreements. For external institutions, connectivity to GPN2 is usually established through their national research and education networks (NRENs) or other international high-performance network providers, often involving cost-sharing agreements or reciprocal service arrangements.

Alternatives

While CERN-GPN2 is a specialized service tailored for the unique needs of CERN and its research community, other high-performance network providers and services exist for different contexts:

• National Research and Education Networks (NRENs): Organizations like Internet2 (USA), GÉANT (Europe), and CANARIE (Canada) provide high-speed networking for academic and research institutions within their respective countries or regions.
• Commercial Cloud Providers: Services like Amazon Web Services (AWS), Google Cloud Platform (GCP), and Microsoft Azure offer robust global network infrastructure and high-bandwidth connectivity options, though typically geared towards commercial applications and may not offer the same level of specialized scientific networking features.
• Internet Exchange Points (IXPs) and Transit Providers: Commercial entities that facilitate internet traffic exchange and provide global internet connectivity, often used by enterprises and ISPs.
• Other Large-Scale Research Networks: Similar to CERN, other large scientific organizations or collaborations may operate their own dedicated high-performance networks to support their specific research endeavors.
