Postbank - Germany

Claim To Fame: 

In 1996 the Postbank set up its backbone based on the ATM technology (AsynchronousTransfer-Mode) and extended it continuously ever since. The backbone reached the end of its life cycle in 2007. Additional expansions could only have been realized by increasing complexity and expenditures, which was not appropriate from an economic and technological point of view.  Therefore the project “New Backbone” was initialized, aimed to evaluate and then implement new technologies.

Organisation Type: 
Large Enterprise
Main benefits & Achieved Results : 

The most important economic value of performed measures beside a quick “return of investment” was the reduced energy costs due to energy savings (about 58 %). In respect to the improved security and increased availability this results in a significant marketing potential on the provided services. Summarized important aspects:

  • New network equipment with life cycle of 10 years ▪ Return of invest is about 18 month;
  • Switch replacement is linked to server life cycle due to soft migration.
Presentation of the initiative: 

For this project, a new backbone based on MPLS (Multi-Protocol-Label-Switching) has been chosen and installed in the system. With the MPLS technology a physical network is divided into logical, independent subdivisions or clients. This virtualization meets increased demands in terms of scalability and easy network management, as well as the protection of data connections from unauthorized access.
After the introduction of the MPLS backbone, network components in the data centre were removed and replaced with new components step by step. These components and the associated change in technology provide different logical networks and even network ports, while the old technology made use of dedicated hardware and electric lines. Thanks to the subdivisions the new system allows, necessary hardware could be reduced dramatically at all sites.

Commitments for the future & other relevant information: 

Postbank use state-of-the-art technologies and conduct a modern life-cycle system to save natural resources. Ecological standards in procurement are part of Postbank’s environmental management system.
