Swisscom is Switzerland's leading telecommunications provider, with 5.5 million mobile customers and 1.8 million broadband connections. Their challenges are to implement URL (Uniform Resource Locator) filtering for 5,000 schools and 900,000 users, ensure efficient, centralized load balancing and deliver flexible administration, stability and high performance. They chose F5 to overcome these challengers. They have implemented F5 BIG-IP Local Traffic Manager (LTM) and VIPRION proxy Virtual IPs (VIP). The results of implementing F5 were excellent performance and reliability, centralized administration of 30 filtering policies, flexible policy setting to meet different regional requirements and long-term scalability.
