Service level agreements on IP networks
@article{Jain2004ServiceLA, title={Service level agreements on IP networks}, author={Gaurav Jain and Deepali Singh and Shekhar Verma}, journal={Proceedings of the IEEE}, year={2004}, volume={92}, pages={1382-1388} }
This paper provides an overview of service level agreements (SLAs) in IP networks. It looks at the typical components of an SLA and identifies three common approaches that are used to satisfy SLAs in IP networks. The implications of using the approaches in the context of a network service provider, a hosting service provider, and an enterprise are examined. While most providers currently offer a static insurance approach toward supporting SLAs, the schemes that can lead to more dynamic…

A new traffic engineering approach for QoS provisioning and failure recovery in SDN-based ISP networks
- Computer Science, Business2018 23rd International Scientific-Professional Conference on Information Technology (IT)

The proposed SDN controller design outperforms the competitive one, which is commonly used in MPLS-based ISP networks, even when TE optimization is repeated after relatively long time intervals, which alleviates concerns regarding the scalability of the SDN control plane in large-scale ISP networks.
