Middleware for managing a large, heterogeneous programmable network
The links between BTexact Technologies and the Department of Computing Science at University College London are becomingincreasingly beneficial for the development of the middleware area for the management of programmable networks. This paperdescribes the work that has been done to date, and outlines the plans for future research
Building Programmable Wireless Networks: An Architectural Survey
In recent times, there have been a lot of efforts for improving the ossified
Internet architecture in a bid to sustain unstinted growth and innovation. A
major reason for the perceived architectural ossification is the lack of
ability to program the network as a system. This situation has resulted partly
from historical decisions in the original Internet design which emphasized
decentralized network operations through co-located data and control planes on
each network device. The situation for wireless networks is no different
resulting in a lot of complexity and a plethora of largely incompatible
wireless technologies. The emergence of "programmable wireless networks", that
allow greater flexibility, ease of management and configurability, is a step in
the right direction to overcome the aforementioned shortcomings of the wireless
networks. In this paper, we provide a broad overview of the architectures
proposed in literature for building programmable wireless networks focusing
primarily on three popular techniques, i.e., software defined networks,
cognitive radio networks, and virtualized networks. This survey is a
self-contained tutorial on these techniques and its applications. We also
discuss the opportunities and challenges in building next-generation
programmable wireless networks and identify open research issues and future
research directions.Comment: 19 page
Agents in Network Management
The ubiquity and complexity of modern networks require automated management and control. With increases in scale, automated solutions based on simple data access models such as SNMP will give way to more distributed and algorithmic techniques. This article outlines present and near-term solutions based on the ideas of active networks and mobile agents, which permit sophisticated programmable control and management of ultra large scale networks
Techno-Economic Assessment in Communications: New Challenges
This article shows a brief history of Techno-Economic Assessment (TEA) in
Communications, a proposed redefinition of TEA as well as the new challenges
derived from a dynamic context with cloud-native virtualized networks, the
Helium Network & alike blockchain-based decentralized networks, the new network
as a platform (NaaP) paradigm, carbon pricing, network sharing, and web3,
metaverse and blockchain technologies. The authors formulate the research
question and show the need to improve TEA models to integrate and manage all
this increasing complexity. This paper also proposes the characteristics TEA
models should have and their current degree of compliance for several use
cases: 5G and beyond, software-defined wide area network (SD-WAN), secure
access service edge (SASE), secure service edge (SSE), and cloud cybersecurity
risk assessment. The authors also present TEA extensibility to request for
proposals (RFP) processes and other industries, to conclude that there is an
urgent need for agile and effective TEA in Comms that allows industrialization
of agile decision-making for all market stakeholders to choose the optimal
solution for any technology, scenario and use case.Comment: 18 pages, 1 figure, 2 table
Platforms and software systems for an autonomic internet
The current Internet does not enable easy introduction and deployment of new network technologies and services. This paper aims to progress the Future Internet (FI) by introduction of a service composition and execution environment that re-use existing components of access and core networks. This paper presents essential service-centric platforms and software systems that have been developed with the aim to create a flexible environment for an Autonomic Internet.Peer ReviewedPostprint (published version
