The Dresden Student Network Working Group (AG DSN) operates a campus network that connects all the students’ union residence halls with each other, with the Technical University Dresden network and with the internet. 从规划, configuration and software development to financial management, all the work is done on a voluntary basis by approximately 50 active AG DSN members.

使用SPB, we can provide each student with their own Layer 2 domain – regardless of whether they are at home or visiting friends at the other end of the campus.

Desafios

AG DSN's campus network provides approximately 4,000 students living in Dresden's halls of residence, with connectivity to the university network and the internet. The existing network could no longer meet current requirements. In order to provide each student with their own Layer 2 domain, both on the wired connection and on the wireless LAN, a new network technology was needed, as the switches in use only supported classic Ethernet and the Spanning Tree Protocol (STP).

AG DSN decided to update the data transmission layer (Layer 2) of the network, based on modern switches that are more efficient and support 最短路径桥接 (SPB). Unlike分, SPB ensures a loop-free topology using the shortest paths between Layer 2 devices, 以及并行路径的使用. Even large networks can be easily configured, efficiently operated and flexibly scaled without issues.
