The purpose of this project is to transition George Mason’s current network architecture to the next generation of network architecture in direct support of the University’s strategic goals by offering an expanded virtual classroom capability and improved research infrastructure platform to better retain and attract students and faculty, as well as improve the user experience by improving network capacity and performance for students, faculty, staff, and guests.
Background & Approach
George Mason’s core network is built on 10Gbps link technology, but the current industry trends are 100Gbps and 400Gbps link technologies.
George Mason invested in a new core to replace aging equipment, scale its core capacity, and take advantage of the efficiencies and features. Additionally, the new architecture and infrastructure will allow us to employ more automation and allow easier updates to network configuration.

Phase I
After discussions with several network equipment vendors, ITS expressed interest in a handful of vendors. ITS developed a set of requirements and tested potential network equipment replacements, avoiding vendor-proprietary technologies inasmuch as possible.
- Site Survey. (Complete)
- Testing and configuration of different vendor solutions. (Complete)
- Security Risk Assessment. (Complete)
What to Expect
No impact is expected.
Phase II
ITS took delivery of equipment and worked with vendors and staff to install power and equipment.
- Equipment Delivery. (Complete)
- Install power. (Complete)
- Install Arista hardware side-by-side to Cisco hardware. (Complete)
- Connecting and configuring routers and switches in preparation for the cutover.
What to Expect
No impact is expected.
Phase III
ITS will deploy (cutover) the core routers then the provider edge routers, then rebuild links, verify routing, forwarding, and reachability on switches. In a network, core routers connect provider edge routers that connect switches.
- Core router deployment
- Provider edge router deployment
- Rebuild links, verify routing, forwarding, and reachability on switches.
What to Expect
Little to no impact is expected; however, if ITS encounters issues, there may be intermittent wired and Wi-Fi network outages during the designated maintenance window. Most work will be done at night, early mornings, or on the weekend to minimize any possible impact. Cell service will not be impacted. The ResNet network will not be impacted, unless otherwise noted in posted maintenance.

Phase IV
ITS will decommission and remove Cisco hardware.
What to Expect
No impact is expected.
