Scalable service deployment on software-defined networks

Abstract

It is widely accepted that the network of the future will require a greater degree of service awareness and optimal use of network resources. This article presents an architectural design for an open software-defined network infrastructure that enables the composition of fast and guaranteed services in an efficient manner and the execution of these services in an adaptive way, taking into account better shared network resources provided by network virtualization. Validation results are provided with special emphasis on service deployment scalability over virtualized network infrastructures.Peer ReviewedPostprint (published version

Towards a Secure Network Virtualization Architecture for the Future Internet

“…Therefore, in future work, we will investigate the relations of the architecture with the main design principles for the Future Internet [30], and how we can improve it by applying them. In particular we would analyse the GVA's realization as part of Software Defined Networks [34] and Network Virtualization Functions [1]. After that we plan to continue the evaluation of the architecture by building a prototype intended to perform extensive experimentation.…”

SDN-Enabled Communication Network Framework for Energy Internet

“…It proposes a flexible, effective, and reliable network framework that abstracts the control plan from the packet forwarding hardware (data plane) to an external software controller [14,15]. Therefore, SDN is perceived to have tremendous potential for utilization in the communication network of the energy Internet.…”

Open the Way to Future Networks – A Viewpoint Framework from ITU-T

“…One method is to enable network operators to control their networks in a unified and programmable manner, and realize multiple isolated and flexible innetworks in order to support a broad range of network services that do not interfere with each other. From this viewpoint, promising technologies includes network virtualization [10][21] and SDN [14], and cloud networking [13][17] [18][19] [20] technologies.…”

“…The research community and the telecom industry have made continuous efforts to investigate and develop Future Networks (FNs) technologies and systems. Various technologies such as network virtualization [10] and software defined networking (SDN) [14][17] [19][21], cloud networking [13][18] [20], information centric networking (ICN) [8], autonomic management [7][11] [12], and open connectivity have been Objectives and Design Goals, describes four objectives and twelve design goals for FNs and as such it presents the first standard definition and description of FNs. The fundamental difference between FNs and other transport networks systems such as those using the Internet Protocol (IP) is the shift from a separate transport and service strata to a packet-based network with service and management-aware characteristics, which is based on shared (virtualized) combined processing, storage and communication / connectivity resources.…”
