Next Generation Network

Next Generation NetworkFrom its beginnings at the dawn of the Internet era, Princeton’s now-150,000-Mbps network has well served the demands of our growing campus community. Built, safeguarded, and continually enhanced by a dedicated, cross-functional team, that network has also grown markedly, encompassing an order of magnitude bandwidth increase every five years.

As we look toward the horizon, new IT developments, emerging research techniques, and fast-evolving campus needs have inspired an ambitious network redesign. Dubbed the “Next Generation Network,” and outlined in the Campus Master Plan, the initiative complements the recent overhaul of our data centers and ongoing classroom-technology upgrade. Central to Princeton’s plans to grow an increasingly robust innovation ecosystem, the project echoes the motives that drive all of OIT’s work: supporting faculty innovation, delivering world-class education to world-class students, and meeting the technology curve across disciplines.

Campus Benefits

In 2018, 300,000+ devices leveraged the campus network. This number is expected to grow to a million-plus over ten years. Reimagined for superior performance, the Next Generation Network reflects the most significant leap forward in the history of networking at Princeton.

Built for speed

The NGN team plans for a lightning-fast one terabit (Tb) per second of connectivity by 2023, a critical gain as data-intensive research proliferates and campus technology use expands.

Crafted to enhance capacity

A re-invisioned network primes Princeton for developments including an expanded footprint, device proliferation, software automation, and deeper engagement with partners bth on campus and beyond.

Optimized for wireless

Plans for the network fully align with the evolution toward a wireless, always-on world where data and information must flow seamlessly and securely 24/7.

Safeguarded with visionary security

Powered by responsive security features, tangible network enhancements will drivereal-time response to real-time threats, while privacy-preserving upgrades safeguard University information.

Designed for resilience

Smart architecture and rapid-healing capabilities will meet the 99.999% uptime-demand of critical systems, with even greater performance planned across the life of the project. 


1/2019 - Streamlined device registration in SN@P

An enhanced asset registration process for wired and wireless devices marries network registrations and asset management and promotes one-stop device management.

  • What to expect:
    • New device registration process:  Device registration is facilitated through SN@P, replacing host database registration. 
    • Host Database retires: The host database will no longer accept device registration.

11/2018 - Upgrade to Campus Wireless Services

In preparation for the retirement of “puwireless” in early 2019, a robust, scalable secure wireless infrastructure was launched. The new solution offers simpler registration, greater security, and technology aligned with the NGN initiative.

  • What to expect: Princeton wireless users now have three options from which to choose:
    • Eduroam - The primary wireless network for use by faculty, students, staff, and visitors from other eduroam-supported academic institutions.

    • ServiceNet - The wireless network that supports devices and Internet of Things (IOTs) that cannot use eduroam because of incompatible login options.

    • PUVisitor - The wireless network that provides 7-day or one year short-term access to visitors to campus.
