Enterprise Campus LAN

With BEUL to the state of the art enterprise campus network

A company from the chemical industry modernized the network infrastructure of its headquarter, a campus complex consisting of several buildings with production, development and research. Due to a campus LAN that had grown organically over decades, the customer's network structure had numerous problems and legacy issues.

In addition to an upgrade to multiple 10G uplinks in the primary and secondary cabling and Power-over-Ethernet Class 4 (up to 64 watts) in the tertiary area, the failure safety of the campus LAN should be maximized through redundant cable routes, stacking and chassis virtualization. Other goals were minimizing the administrative surface by centralizing the switch control planes and extremely clean patch cabling, including color coding and ring markings in the distribution rooms.

Based on a classic block design, routed core/distribution and switched access layers were implemented on the campus, which works completely free of outdated loop prevention mechanisms such as Spanning-Tree Protocol (STP), but functions as a high-performance active-active fabric. Cisco Catalyst switches of the 9200 and 9400 series were used as systems.

BEUL assisted the customer with network design, hardware, software and cabling preparation, rollout with multiple installation teams and system documentation. The end product was a state-of-the-art enterprise campus network with very high resilience, maintainability and scalability for the customer.
