The service level agreement (SLA) specifies the service availability that a service provider
promises to a customer. Through introducing SLA into optical packet switching networks, a …

This paper focuses on the design and implementation of a low-complexity dialogue
mechanism between the management and transport planes of an all-optical network. This …

Current network operators are focused mainly on providing and selling network services on
top of the network infrastructures they own and manage. The end user has no control over …

Network automation is the current challenge that operators face to accelerate end-to-end
service delivery and improve network operations in the context of rapidly growing capacity …

We propose a semicentralized semidistributed network architecture based on active stateful
path computation elements (PCEs) to intelligently provide end-to-end inter-domain …

The Future Internet will see the emergence of value-added applications (eg telepresence,
etc.) requiring Quality of Service (QoS) guarantees across multiple managed networks …

Traffic in the Internet backbone is expected to grow above a few Tbit/s in 2020. To cope with
this, operators are moving to IP/optical network architectures, where IP is the convergence …

Network virtualization is a key enabling technology for “Infrastructure as a Service”
provisioning, increasing the flexibility and cost savings offered to customers. By extending …

The rapid growth of network services is forcing operators to use of inter-layer coordination
between the IP and the transport network management systems in order to optimize …
