The document is a network topology diagram for the City of Pittsburgh's data center infrastructure, depicting the current and proposed network configuration for a data center move. The diagram illustrates a high-availability (HA) network design spanning two locations: a primary CCB (Core Computing Building) and a DR/Co-Location site. The network architecture includes multiple network components such as edge routers (Cisco ISR4331), firewalls (Fortigate 2601F, Cisco ASA5545), VPN hubs (Meraki MX250), core switches (Cisco C9606 and C3850), and routers (Cisco ASR1001-X). The design incorporates connections to external services including DQE (Data Quality Enterprise), Expediant Internet, Crown Castle, and Google Cloud Platform (GCP).

The network topology emphasizes redundancy and high availability, with mirrored equipment configurations at both the CCB and DR/Co-Location sites. Each site features matching network devices with HA links, ensuring continuous operation and failover capabilities. The infrastructure supports multiple connectivity paths, including internet access, cloud connectivity, and potential disaster recovery scenarios. Key vendors in the proposed architecture include Cisco, Fortigate, Meraki, and involves integration with cloud and internet service providers. The diagram suggests a comprehensive approach to network design that prioritizes resilience, performance, and flexibility for the City of Pittsburgh's data center infrastructure.
