Today's Communications Service Providers (CSP) are either working on, or planning the transition to, IPv6. European Tier-1 mobile operator with approximately 10 million subscribers. Their challenge is to preserve complete subscriber awareness in an environment in which multiple subscribers share the same IP address; doing so would ensure that personalized services are still delivered. They chose Sandvine to overcome this challenge. They have implemented Sandvine session qualifiers technology, which is a feature of their network policy control platform. Since this operator was an existing customer, they gained access to session qualifiers via a free software upgrade. The results of implementing Sandvine were no impact to services despite massive network changes. Operators benefitted from their customers and a reprieve from IPv4 address exhaustion.
