An open virtual multi-services networking architecture for the future internet

Abstract

Network virtualization is considered as a promising way to overcome the limitations and fight the gradual ossification of the current Internet infrastructure. The network virtualization concept consists in the dynamic creation of several co-existing logical network instances (or virtual networks) over a shared physical network infrastructure. We have previously proposed a service-oriented hierarchical business model for virtual networking environments. This model promotes the idea of network as a service, by considering the functionalities offered by different types of network resources as services of different levels -services that can be dynamically discovered, used, and composed. In this paper, we propose an open, virtual, multi-services networking architecture enabling the realization of our business model. We also demonstrate the operation of our architecture using a virtualized QoS-enabled VoIP scenario. Moreover, virtual routing and control level performance was evaluated using proof-of-concept prototyping. Several important findings were made in the course of this work; one is that service-oriented concepts can be used to build open, flexible, and collaborative virtual networking environments. Another finding is that some of the existing open source virtual routing solutions such as Vyatta are only suitable for building small to medium size virtual networking infrastructures.

Method for estimating the effective data rate in 802.11 channels by using a monitoring algorithm

“…Modern multiservice networks, providing access to communication services, in most cases use TCP / IP family of protocols, and the principle of transparent transfer of traffic, which from the point of view of user does not depend on the type of transmission channel (Barachi, Kara, Rabah, & Forgues, 2015). One of the common channel building technologies is the 802.11 standard , which includes the function to quickly deploy local area networks in corporate and home sectors, easy connection of user equipment, and low cost of equipment (Perahia & Stacey, 2013).…”

Development of Information Models for Increasing the Evaluation Efficiency of Wireless Channel Parameters of 802.11 Standard

“…One of the common channel building technologies is the 802.11 standard, which includes the function to quickly deploy local area networks in the corporate and home sectors, easy connection of user equipment, and low cost of hardware [1]. The development of the 802.11 standard made a contribution to the widespread introduction of the concept of the Internet of Things and increasing requirements for bandwidth channels.…”
