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. The LAN is segmented into various subnets, partly for data security reasons. Different access requirements and configuration parameters apply to each network segment. 

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.

User Support

• Support for the service is generally provided as part of the kiz-wide, standardised, two-tier (1st & 2nd level) incident and request management system. The first point of contact is therefore the helpdesk, which systematically records enquiries and problem reports and, where necessary, escalates them to the specialist staff at the 2nd level.
• Due to the large number of users and the high degree of standardisation of support cases, additional service features are offered:
  • Requests relating to standard cases (including the registration and deregistration of computers or IP addresses, change-of-address notifications, the reactivation of blocked addresses, and the activation of network sockets) can be submitted online via web-based forms.
  • Fault reports can be submitted online via web-based forms.
  • Creation and maintenance of FAQs on common errors and problems, including guidance on how to resolve them independently.

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
