摘要：
As VoIP services proliferate due to rapid advances in technology and market demands, service providers are aggressively looking for better ways to offer VoIP services to customers including support of different codec technologies via a single network access point. This service flexibility introduces major traffic engineering challenges, especially when supporting a mix of data and voice services. In order to guarantee individual source's call blocking probability, intelligence must be added to the call admission process. To tackle the issue, we propose an intelligent call blocking algorithm that is guided by a pre-defined blocking targets.
