Differentiated Services (DiffServ) for Quality-of-Service (QoS) Network Traffic requires Efficient Capacity
Differentiated services (DiffServ) is an architecture that specifies a simple, scalable, and coarse-grained mechanism for classifying, managing, and providing quality-of-service (QoS) to the network traffic on IP-based networks. However, efficient and accurate capacity provisioning in this architecture is significantly challenging.
Algorithm Technology Delivers Efficient, Scalable Automatic Capacity Provisioning for Large Multi-Service Networks
The technology provides a suite of algorithms capable of delivering automatic capacity provisioning in an efficient and scalable manner. These algorithms make most policy rules unnecessary and simplify the provisioning of large multi-service networks. The technology can enable quantitative service differentiation, improve network utilization, and increase the variety of network services that can be offered to customers.
Applications:
• Voice-over-IP
• Rolling out new IP-based services
Advantages:
• Improved QoS
• Make policy rules unnecessary
• Significant cost savings to the service provider
