Azienda Ospedaliero Universitaria Policlinico Di Catania | Healthcare | 2000 | $650M | Italy | Cisco Systems | Cisco ISR 4321 Routers | Routers and Network Switches | 2018 | n/a |
In 2018, Azienda Ospedaliero Universitaria Policlinico Di Catania deployed Cisco ISR 4321 Routers as part of its Routers and Network Switches teaching infrastructure in the Department of Electrical, Electronic and Computer Engineering. The Cisco ISR 4321 Routers are installed to support classroom and laboratory exercises, explicitly linking hardware-level routing and voice capabilities to academic instruction in communications engineering.
The deployment is configured to deliver core routing and packet forwarding functions alongside voice support for VoIP lab scenarios, and to enable IoT networking practicals typical of Routers and Network Switches equipment. Configurations emphasize hands-on exposure to routing topologies, interface and VLAN segmentation, and voice gateway behavior to reflect standard networking and VoIP operational workflows used in teaching.
Hardware and software usage is scoped to the DIEEI Internet & Computer Network laboratory and is integrated into the Communications Engineering master program curriculum for teaching and research. The Cisco ISR 4321 Routers support lab modules covering networking, VoIP, and IoT practicals, providing students with live device access and real-world routing and VoIP lab experience.
Governance is academic and laboratory focused, with the router infrastructure used for coursework and research experiments rather than enterprise production services. The implementation centers on practical instruction, instrumenting Cisco ISR 4321 Routers within laboratory workflows to align device configuration, lab exercises, and research activities with program learning objectives.

Swinburne University of Technology | Education | 2702 | $600M | Australia | Cisco Systems | Cisco ISR 4321 Routers | Routers and Network Switches | 2017 | n/a |
In 2017, Swinburne University of Technology deployed Cisco ISR 4321 Routers in networking lab kits used for TNE10006 and TNE60006 practicals in Australia. The Cisco ISR 4321 Routers were provisioned as part of the Routers and Network Switches teaching infrastructure to provide students with hands on routing experience and practical router configuration and network troubleshooting exercises for undergraduate networking courses.
The classroom deployment is organized around lab kit topology templates and CLI based device configuration, focusing on routing workflows, packet forwarding, interface configuration, and supervised troubleshooting practice. Devices are configured to support reproducible lab exercises and course documentation lists the Cisco ISR 4321 Routers as primary routing equipment for the networking practicals. Operational scope is education and training within Swinburne's networking labs in Australia, with teaching staff managing configuration and lab exercise governance through course materials.

Texas State Technical College | Education | 1000 | $147M | United States | Cisco Systems | Cisco ISR 4321 Routers | Routers and Network Switches | 2019 | n/a |
In 2019 Texas State Technical College deployed Cisco ISR 4321 Routers in its NETLAB+ data center at the Waco campus. The deployment is documented in NETLAB+ materials and is part of an NSF funded online competency based education project delivering remote networking labs across the United States. The Cisco ISR 4321 Routers implementation is categorized as Routers and Network Switches and supports the college's remote lab infrastructure.
Each NETLAB+ POD at the Waco data center includes two Cisco ISR 4321 routers, configured to present remote access networking lab environments and to create a repeatable POD architecture for hands on networking exercises. Functional capabilities emphasize remote access to lab devices, session isolation, and packet level connectivity consistent with networking lab workflows. This Routers and Network Switches deployment supports education and IT operations by enabling remote hands on labs and improved student access to networking lab environments, and it is scoped to the Waco campus NETLAB+ data center in support of the NSF competency based education project.

U.S. Geological Survey | Government | 10000 | $1.9B | United States | Cisco Systems | Cisco ISR 4321 Routers | Routers and Network Switches | 2009 | n/a |
In 2009, U.S. Geological Survey implemented Cisco ISR 4321 Routers as part of its network infrastructure rollout. The deployment is classified under Routers and Network Switches and centered on edge routing functions for agency sites supporting scientific data collection and field operations.
Cisco ISR 4321 Routers were configured to provide standard router capabilities including WAN edge routing, VPN termination, IP routing, and quality of service controls typical of enterprise router deployments. Configuration work emphasized interface provisioning, routing protocol configuration, and firmware and software baseline management to maintain consistent operational behavior across sites.
The current procurement request focuses on an Equipment Maintenance Service Plan to support Cisco ISR 4321 Routers alongside other Cisco routers, switches, and phone systems in Alaska, indicating operational coverage for USGS network operations and telephony support in that region. The maintenance scope explicitly includes hardware support and associated software maintenance to sustain routing, switching, and voice infrastructure used by IT infrastructure and network operations teams.
Contract governance and procurement milestones are clearly defined, the contract period is from September 1, 2025, to August 31, 2026, with options for four additional years subject to funding availability. Interested contractors must submit proposals including a completed SF 18 form, technical qualifications, and pricing by August 1, 2025, questions are due by July 11, 2025, and inquiries may be directed to Yangzhi Deng at yangzhideng@usgs.gov or 916 278 9326.
