The Civil Engineering department is part of the Department of Construction, Transport and Environment of the Swiss canton of Aargau. It ensures the economically and ecologically balanced construction, maintenance and operation of the cantonal road network of approximately 1,200 kilometres as well as the cycle paths in Aargau. The electrical engineering section is responsible for all the road network electromechanical installations, such as operational and safety equipment in the tunnels, and the fibre optic network through which all systems communicate.

Challenges
The canton of Aargau has relied on Alcatel-Lucent Enterprise solutions for its network since 2013, when the entire infrastructure was procured through a public tender. The basic deployment of the new network went live in 2014 and has been gradually expanded and optimised over the years.
Action
As a result of a comprehensive analysis of the network and its connected systems in 2019, further measures were planned and implemented through 2023. Individual components were replaced with newer models, 加强网络安全, and centralised management of all tasks, 由自动化工具支持, 介绍了.
Prepared by a core redesign in 2020, the Spanning Tree Protocol (STP) was replaced with 最短路径桥接(SPB) in the latest expansion stage. SPB finds the shortest paths between end devices and allows paths to be used in parallel. Since the backbone forms a triangle, SPB可以使所有链路保持活动状态, to maximise bandwidth utilisation. 服务 can be switched on using zoning protocols, increasing the security of the data network and enabling additional services in the future. The project was completed in 2023.
Results
技术的好处
- Powerful, reliable ALE switches for all areas, including hardened switches where required
- All switches use the same firmware version, simplifying configuration and operation
- With the service-oriented SPB technology, even large networks can easily be configured, efficiently operated and scaled with no problems
- Ethernet Ring Protection increases network stability and reliability
- High availability through redundant installation at most locations
- ALE network management OmniVista 2500 integrated seamlessly into the existing network management
- Smooth interaction with the third-party monitoring tool
经济利益
- “物有所值”
- The network is built using (almost) exclusively ALE components, which simplifies contracting and sourcing
用户体验优势
- The network provides a reliable foundation for current and future services, completely transparent to the end users
- “这很管用。. And when it doesn't, you'll know right away.”
