Packet Design manages HL komm's IP traffic

HL komm Telekommunikations, a regional service provider in eastern Germany, has deployed IP-based route and netflow analysis system from Packet Design to manage the growing IP network which provides its customers with internet access, data and voice over IP (VoIP) services.

Traffic Explorer enables HL komm to monitor customer traffic as it moves from end to end over the backbone network, helping the Leipzig-based service provider to do more effective troubleshooting and capacity planning, and to make cost-effective decisions about peering relationships with other providers outside the region.

Gregor Türpe, design engineer at HL komm, said the need for more visibility into routing and traffic became apparent over the last several years as HL komm's network grew into a major backbone spanning many cities and offering converged services to business customers and other carriers.

Today that backbone carries data and voice traffic to more than 50,000 end users, many of them purchasers of 'triple play' service packages through HL komm's cable-provider partners.

'As we expanded our IP backbone to increase network capacity, we suddenly had a lot of bandwidth, many more routers and much more complexity to manage,' Türpe said. 'And when we added IP-based voice services, the network's stability and the need to avoid service degradation became much more important. We were in need of new tools.'

On a daily basis, HL komm uses Traffic Explorer to diagnose network problems on its Cisco router-based network and find their causes.
