Network & Security

The High-Performance Computing (HPC) system at Tribhuvan University is hosted at the Information Technology Innovation Center (ITIC), Tribhuvan University. The system ensures secure, reliable, and high-speed connectivity for researchers accessing computational resources remotely or within the university network.

Network Architecture

The TU HPC network infrastructure is built for efficient data communication and secure remote access. It consists of:

1. Hosting & Connectivity

  • The HPC system is physically hosted at TU ITIC.
  • Network Address Translation (NAT) is managed by TU ITIC and the TU Registrar Office.
  • Connectivity is based on a standard Ethernet network, not Infiniband.

2. External & Internal Access

  • Remote Access: Users connect to the HPC system via SSH (Secure Shell).
  • Internal Network: Compute nodes communicate over a local Ethernet network.

3. Data Transfer

  • Secure file transfer via SCP, SFTP, and Rsync.
  • Scratch storage for temporary data transfer optimization.

Security Measures

TU HPC implements multiple security policies to protect user data and system integrity:

1. User Authentication & Access Control

  • Centralized authentication system to manage user credentials.
  • SSH key-based authentication for secure remote access.
  • Role-based access control (RBAC) to restrict administrative privileges.

2. Firewall & Network Security

  • Firewall rules managed by TU ITIC to restrict unauthorized access.
  • Network traffic monitoring to detect and mitigate suspicious activity.
  • Isolation of compute nodes from direct external access for security.

3. Data Protection & Compliance

  • Regular system backups for critical user data only.
  • Data encryption for sensitive research projects.
  • User activity logging for compliance and audit purposes.

Future Enhancements

TU HPC aims to improve networking and security infrastructure by:

  • Implementing VPN-based secure access for external researchers.
  • Expanding network bandwidth to support larger datasets and AI workloads.
  • Enhancing intrusion detection systems (IDS) and automated monitoring.
