林雪平大学 (LiU) in southern Sweden conducts interdisciplinary research and offers innovative educational programmes, 通常以职业为重点. The university is spread over four campuses in three cities. Its 35,900 students and 4,300 employees are all supported by one IT team.
Challenges
林雪平大学’s network no longer met its requirements. The standard three-tier architecture with a routed core could not offer the speed, 今天的期望是弹性和灵活性. 设置, configuration and network management were complex and time-consuming, 设备又旧又慢, 卖主也不太支持我.
Action
In order to standardise and stabilise the network, 满足用户期望，降低成本, LiU decided to implement a modern network solution from Alcatel-Lucent Enterprise (ALE). The project started with the implementation of the access layer in 2015, followed by the core switches and a Shortest Path Bridge (SPB)-based campus solution connecting all four sites. 最后, the data centre (DC) networks in Linköping and Norrköping were replaced and integrated into the SPB fabric, enabling the support of virtual clients and of servers outside the DC. A new network management system (NMS) was also implemented.
经过仔细评估, 林雪平大学 decided to use Shortest Path Bridging for their new campus network which offered simplified management, 高度自动化的开关配置, 以及可观的成本节约. 现有架构, which included hand-built tunnels and direct physical connections for L2 connectivity, 在2017年被淘汰并被SPB取代.
The physical and logical network architectures are now completely separated. 用户可以使用任何设备进行连接, 在任何地方, 任何时候, 只要连接到任何网络套接字, and they are automatically connected to the right part of the network (containment). This frees up time and resources so that the IT team can provide more focus and additional services to their customers.
