Service Category: Network & Connectivity

The LAN (Local Area Network) service provides Ulm University with the local, wired network for IP data traffic. On the one hand, the service is a fundamental component of the information and communication infrastructure on which other services of the kiz and other university facilities are based. On the other hand, the LAN provides users with a fixed network-based access to the campus network and the Internet for their own end devices, which receive a fixed and worldwide unique IP address as well as a DNS entry.

Service description

• Provision of a wired data connection for workstations, servers and other end devices in all designated areas of the university (in particular offices, server rooms, laboratories, lecture theatres, seminar rooms)
  • Physical connection types:
  • 10/100 BaseT (Twisted Pair Ethernet 10/100 Mbit/s)
  • 1000 BaseT (Twisted Pair Ethernet 1Gbit/s) - mostly available
  •  10 Gbit/s Ethernet - in the server rooms or in justified exceptions also very limited in other rooms
• Support of the IP protocols IPv4 and IPv6
• To use the data connection, the end devices connected to the network must be registered. One or more IPv4/IPv6 addresses from the Ulm University address space are assigned by kiz, some of which uniquely identify the end device worldwide.
• The use of the assigned and registered IP addresses is limited to the respective network segment.
• Dynamic DHCP address allocation is set up for sub-networks on request if certain administrative requirements are met.
• The wired data network is segmented into subnetworks for reasons of data security, as well as for reasons of logical separation of usage types and user groups:
  • Research and Teaching (F&L)
  • Central University Administration Building Helmholtzstraße 16 (ZUV)
  • Central university administration other than building Helmholtzstraße 16 (ZUV-Campus)
  • Building management system (GLT)
  • Telecommunications (TK)
• Segmentation can be logical and/or physical. The subnets may be segmented into further subnets.

User groups

Depending on the network segment, the following user groups can be identified:

• F&L: All members as well as institutions of Ulm University, unless they are connected to other subnetworks
• GLT: ZUV Department V-3 Building Automation and Electrical Engineering as well as the contractors involved
• TK: all administrators of the TK system as well as the contract companies involved
• ZUV: all ZUV employees in the building Helmholtzstraße 16
• ZUV Campus: ZUV employees at locations other than the building at Helmholtzstraße 16
