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. From planning, configuration and software development to financial management, all the work is done on a voluntary basis by approximately 50 active AG DSN members.
挑战
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 Shortest Path Bridging (SPB). Unlike STP, SPB ensures a loop-free topology using the shortest paths between Layer 2 devices, as well as parallel path use. Even large networks can be easily configured, efficiently operated and flexibly scaled without issues.
结果
