24 January 2003 -- An installation of Extreme Networks' Ethernet switching platforms should help Munich manage its water supply. The modern Metro network, run by SWM-Versorgungs, offers high resiliency from Extreme's Ethernet Automatic Protection Switching (EAPS) technology.

SWM-Versorgungs GmbH selected Extreme's solution to integrate its FDDI fibre ring with Ethernet technology. Extreme says its switching platforms provide increased bandwidth, Quality of Service (QoS) and fault tolerance to support increasing amounts of data traffic.

The EAPS software capability extends SONET-like reliability to ring-based networks, exceeding the performance of Spanning Tree technology. It is also said to improve network resiliency, with sub-50ms recovery of data services should a fibre line be cut or interrupted.

Extreme's Alpine 3800 and Summit®48si switching platforms provide a complete core and edge network solution for SWM-Versorgungs. Critical data traffic can be prioritised with Extreme Networks' QoS functionality to support both existing applications and future considerations for VoIP and streaming video.

"The integration of our Metro optical infrastructure with Extreme's Ethernet platforms have proven to be an economical success," said Ludwig Bentele, head of process control systems at SWM-Versorgungs GmbH.

"We have gained additional bandwidth reserves providing added investment protection. Additionally, Ethernet fits perfectly with our objective to implement a standards-based network, one that is easier to configure and less expensive to operate than FDDI."
