Penn State

RUCKUS® ICX family of swithces delivers more efficient connections

Pennsylvania State University is a public research-intensive university with campuses and facilities throughout Pennsylvania. Ranked as one of the top 50 colleges by U.S. News, Penn State serves 80,000 students and 50,000 faculty and staff. The University Park campus, comprised of several hundred buildings and nearly 32 million square feet, is a city in itself. Penn State is dedicated to implementing innovative solutions and is committed to reducing its carbon footprint and greenhouse gas emissions. A large portion of that has come from its Energy Savings Program that has already reduced its energy use to 2003 levels despite an increase of over one million square feet of building space.

Using separate IT teams for different areas of the university, the facility automation team is innovative in its management of the infrastructure that supports buildings on the University Park campus and the Commonwealth campuses throughout the state. The building automation IT department has implemented the network in over 300 buildings across the University Park campus and up to 170 buildings across the state, controlling such things as heating and cooling, lighting, elevators, vibration monitoring, and anything building related. Tom Walker, network administrator at Penn State, stated, “Anything that deals with control of the building and how the building operates is coming across my network infrastructure and servers at the data center.”

The challenge

Struggling with their legacy network, Penn State was facing some challenges. Using a protocol called BACnet, an open industry standard used in Building Automation and Lighting Systems, Penn State was struggling with the control of broadcast traffic. “We were seeing up to 90,000 packets per hour of broadcast traffic, which caused random buildings to drop offline due to the broadcast storms,” stated Walker. “We needed to change our flat Layer2 daisy-chain design. If I turned off one building, up to 10 more buildings would shut down, which caused even more problems when I just needed to isolate the one that was causing the issues.”

Requirements
  • Implement innovative solutions to reduce carbon footprint and greenhouse gas emissions
  • Reliable network that can support 300 buildings on the University Park campus and 170 buildings across the state
Solutions
  • Deployed ICX 7750 switches at the core, ICX 6610 and ICX 7450 to deliver reliable and scalable L3 routing between the access and the core, and an ICX 6450 or ICX 7150 12 port compact switch is deployed in each building
Benefits
  • Network can support all the buildings throughout the campus and across the state with flexibility to grow with the university’s future needs
  • Reduced power consumption in the buildings
  • Reduced carbon footprint while saving millions of dollars
