Realization of Service-Orientation Paradigm in Network Architectures
The implementation of communication protocols in the current Internetarchitectureistightly-coupledwhichhinderstheevolutionoftheInternet.Thisarticle describes how the principles of Service Oriented Architecture (SOA)can be employed to develop a flexible network architecture. The prototypeof the concept has been developed and demonstrated in the EuroView 2012workshop. We showed that the SOA paradigm can be applied to networksby utilizing the concepts of self-contained building blocks, dynamic protocolgraphs (PGs) and functional composition (FC) methods. We demonstratedthatbothshort-termflexibility(i.e.,networksareadaptedbasedonapplicationrequirements) and long-term flexibility (i.e., networks can be evolved) can beachieved by using the architecture.
Requirements-Aware, Template-Based Protocol Graphs for Service-Oriented Network Architectures
2016
Rigidness of the Internet causes its architectural design issues such as interdependencies among the layers, no cross-layer information exchange, and applications dependency on the underlying protocols implementation. G-Lab (i.e., http://www.german-lab.de/) is a research project for Future Internet Architecture (FIA), which focuses on problems of the Internet such as rigidness, mobility, and addressing. Where the focus of ICSY (i.e., www.icsy) was on providing the flexibility in future network architectures. An approach so-called Service Oriented Network Architecture (SONATE) is proposed to compose the protocols dynamically. SONATE is based on principles of the service-oriented architecture (SOA), where protocols are decomposed in software modules and later they are put together on demand to provide the desired service. This composition of functionalities can be performed at various time-epochs (e.g., run-time, design-time, deployment-time). However, these epochs have trade-off in t...
Towards a Service Oriented Internet
IEICE Transactions on Communications, 2006
Today's Internet remains faithful to its original design that dates back more than two decades. In spite of tremendous diversity in users, as well as the sheer variety of applications that it supports, it still provides a single, basic, service offering-unicast packet delivery. While this legacy architecture seemed adequate till recently, it cannot support the requirements of newer services and applications which are demanded by the growing, and increasingly sophisticated, user population. The traditional way to solve this impasse has been by using overlay networks to address individual requirements. This does not address the fundamental, underlying problem, i.e., the ossification of the Internet architecture. In this paper, we describe the design of a new Service Oriented Internet framework that enables the flexible and effective deployment of new applications and services. The framework we describe utilizes the existing IP network and presents the abstraction of a service layer that enables communication between service end-points and can better support requirements such as availability, robustness, mobility, etc., that are demanded by the newly emerging applications and services.
Connectivity abstractions and “service-oriented network” architecture
2012 International Conference on Computing, Networking and Communications (ICNC), 2012
Current generation networks have been designed only for network connectivity; they have been stretched to the limit with many afterthought add-on features including quality of service, mobility, programmability, and security so that they can be deployed for business applications and processes. As such, service deployment on current networks are difficult, time consuming and with limited successes. This paper suggests a service architecture based on abstraction, abstraction and abstraction. The paper also proposes a service-oriented network (SON) architecture that facilitates the development of services and applications regardless of the underlying network access technologies. The architecture is conceived through the consideration of the essential requirements of generic Internet applications from the service and network providers' perspective that addresses the Service-Oriented Architecture (SOA) application deployment pattern, user location and device mobility, and the structure of IP-converged networks
Describing and selecting communication services in a service oriented network architecture
2010
Today networks offer communication services ranging from a rather simple and unsecure one to secure and reliable data transmission for communicating on the network. In the future, it is expected that networks will offer a large number of different communication services. With so many services available, determining which service to select and use becomes much more difficult. Here we propose a description schema including an ontology for describing communication services. For service selection a decision making process called Analytic Hierarchy Process (AHP) is utilized which is specially adapted and extended for automatic processing.
A Framework of Service Selection and Composition for Flexible Network Architecture
Lecture Notes of the Institute for Computer Sciences, Social Informatics and Telecommunications Engineering, 2013
Internet becomes a back bone of the communication network in the current era. People are very much dependent on the internet to connect from one end to another globally in todays environment. Internet suffers from the problem with the tightly coupled layered architecture. So there should be flexible architecture of internet. Flexible architecture will reduce the tight coupling of the layers. Selection of service and Composition of service is also an issue which will be solve through our framework. So we propose a framework of flexible network architecture which will provide flexibility to user for their application. This framework has many advantages like availability of services, load distribution, service discovery through the cloud technology. Cloud has a group of nodes which will act as single node to discover service and provide a service .It is a capable to create a mirror image of the broker node. Flexible network architecture is a combination of blocks. These blocks are functional module. Our framework will maintain also performance of the network.

The rapid globalization of world enterprises and the pressing need to provide networks and services more responsive to the "end users" push the telecommunications world towards rapid service deployment and new integrated value-added technology solutions. Service orientation, initially introduced in Intelligent Networks and currently further exploited within the Service Oriented Architectures (SOA), seems to be the key for achieving the rapid development of new services with low cost. New value-added services as well as new business models drive the adoption of SOA in the telecommunications world. In this paper, we first discuss the requirements for a service-based approach, and then we overview the traditional service orientation in the telecoms sector, as well a main methodology for service definition and creation. A discussion of telecommunications service management follows together with an investigation of current Service Oriented Architectures, through the provision of some important examples.
Composition of Self Descriptive Protocols for Future Network Architectures
2009
The network protocols we use today have been introduced decades ago. Since then the whole Internet came to existence and with it a single protocol stack: TCP/IP. What was a good solution back then, is no longer appropriate to fulfill the emerging demands of applications. Newer protocols have been created as solutions for the problems, but replacing TCP/IP requires a complicated deployment and migration phase. The problems with the current Internet architecture and its fixed structure have triggered a discussion on a Future Internet architecture. We propose a way to dynamically select and compose protocols based on principles of service oriented architectures. The goal is a network architecture where new protocols could be easily added and are automatically and transparently used by applications. In this paper we present a way to describe protocols and their effects and dependencies between them. We also present a method to select and compose protocols.
2014 European Conference on Networks and Communications (EuCNC), 2014
This paper introduces a new paradigm for service oriented networking being developed in the FUSION project 1. Despite recent proposals in the area of information centric networking, a similar treatment of services-where networked software functions, rather than content, are dynamically deployed, replicated and invoked-has received little attention by the network research community to date. Our approach provides the mechanisms required to deploy a replicated service instance in the network and to route client requests to the closest instance in an efficient manner. We address the main issues that such a paradigm raises including load balancing, resource registration, domain monitoring and inter-domain orchestration. We also present preliminary evaluation results of current work.
