“…Previously, we have also reported on a multidomain, multitechnology (packet, fixed, and elastic) interoperation over an Openflow SDN-based unified control plane [39]. Web-services-based provisioning and control has also been used for deploying central management/control planes in several studies [40,41]. In this work and to facilitate the control of this open network platform, we have implemented a centrally controlled web-servicesbased control framework with a range of supporting software modules.…”

This paper reports on the design, implementation, and evaluation of a multitechnology, multirate, and adaptable network architecture for metropolitan/edge areas. It is empowered by programmability in control and data planes, providing users with an open network platform to redefine and optimize its behavior and performance. It uses a hybrid data plane of fixed-grid [(sub)wavelength] and flex-grid systems to support a broad range of data rates (1 to 555 Gb∕s). The programmability in the data plane is achieved by building the nodes with a modular and flexible architecture (architecture on demand nodes) to achieve different functionalities (fixed-/ flex-grid switching with or without time multiplexing) on demand. A centralized, modular, and scalable control framework has been constructed for this network. It uses a set of software plug-ins designed for architecture synthesis and adaptation for policing network resources access and as algorithms of routing and resource allocation for network operation. The proposed hybrid network architecture, along with allocation policies and resource allocation algorithms, is evaluated through simulations across a broad range of traffic profiles with bandwidth requests stretching from 1 to 400 Gb∕s. Finally, the programmable dataplane/control-plane architecture has been implemented in an experimental testbed and the functionality of the node and network elements individually and together have been tested, demonstrating the feasibility of the system.

Using Virtualization to Provide Interdomain QoS-enabled Routing

Today, the most important aspect related with the Internet architecture is its ossification representing the difficulties to introduce evolutions in the architecture as a way to meet the demands posed by the new requirements as mobility, security, heterogeneity, etc. In this paper we discuss how the network virtualization can be used to support the interdomain QoS-enabled routing. We present the Virtual Topology Service (VTS), a new approach to provide interdomain services taking into account QoS and Traffic Engineering (TE) constraints. We advocate in favor of a service layer that offers new mechanisms for interdomain routing without affecting the underlying Internet infrastructure. The VTS abstracts the physical network details of each Autonomous System (AS) and is totally integrated with BGP. Two models to obtain VTs were defined, the Push Model and the Pull Model. The latter one uses the Internet hierarchy to get more alternative routes towards a destination. We will show how the VTS and other services such as the end-toend negotiation service work together to provide a complete mechanism for provisioning of interdomain QoS- enabled routes in IP networks. Preliminary evaluation results are also presented.
