The City of Allen's computer network backbone has grown over the last two decades along with the City itself. Over time, facility after facility was connected, network speeds were increased, private and leased fiber were implemented, and thousands of network endpoints and wireless devices have been attached.
The size and complexity of Allen's network, like all networks that grow significantly, has outgrown the original simplistic network design, called "Layer 2". Layer 2 is an excellent design for simpler, smaller networks. All devices can "see" each other, which makes communication simpler but introduces fragility and broadcast storms as the network increases in size.
The primary part of this purchase is switch technology from Cisco that upgrades the City's network backbone to Layer 3. Layer 3 adds broadcast network routing capabilities, improves manageability, allows for increased growth, and segments the network to protect against loops and network storms. Layer 3 will be added to the core of the network, improving network resilience and uptime. It also prepares us for having two true paths to the internet, a key factor as the organization continues its use of cloud services.
In addition to wired switches, this purchase also provides new wireless access points to replace the wireless system in many city facilities that is approaching a decade in service. The new wireless will increase capacity, speed, and allow for a secure employee network to improve mobility and productivity for employees.
Finally, services from Presidio are provided on a "bill as needed" basis. Only hours used will be billed. Presidio's expertise in Cisco network design is proven as seen with long-term contracts with other private sector and government entities throughout north Texas including Plano, Garland, Denton, Fort Worth and Denton County. Presidio's design and implementation services will ensure the migration to Layer 3 for Allen's network provides an excellent, stable and agile foundation for future network services.
