A Distributed Cloud Architecture Based on General De Bruijn Overlay Network

Distributed cloud systems enable the distribution of computing resources across various geographical locations. While offering benefits like accelerated content delivery, the scalability and coherence maintenance of these systems pose significant challenges. Recent studies reveal shortcomings in existing distributed system schemes to meet modern cloud application demands and maintain coherence among heterogeneous system elements. This paper proposes a service-oriented network architecture for distributed cloud computing networks. Using a De Bruijn network as a software-defined overlay network, the architecture ensures scalability and coherence. Through service-based addressing, requests are issued to designated service address bands, streamlining service discovery. The architecture's evaluation through extensive simulations showcases sustainable scalability and inherent load-balancing properties. The paper concludes with insights into future research directions, emphasizing the extension of the proposed architecture to emerging distributed cloud use cases and decentralized security.

Multicast at Edge: An Edge Network Architecture for Service-Less Crowdsourced Live Video Multicast

Using smartphones, tablets, and other portable/handheld devices, we have become more reliant on the video streaming services for entertainment and remote work. Mobile data traffic has grown eighteen folds over the past five years accounting for the majority of IP traffic. YouTube Live, Facebook Live, Twitch, DouYu and other streaming as well as video conferencing services have increased in popularity so at any given moment they serve thousands of live video streams to millions of users. The Enhanced Multimedia Broadcast Multimedia Service (eMBMS) is the standard multicast protocol for 5G networks. Cellular multicast has gained considerable attention to efficiently utilize the limited spectrum to transmit multimedia content to cellular sites with co-located viewers, lowering the cost, and maximizing the Quality of Experience (QoE). However, popular live video content providers use unicast mode for live video delivery and have limited support in the eMBMS service-oriented network architecture. In this paper, we propose an overlay network architecture to augment eMBMS to address the limitations of the standard eMBMS architecture and enable service-less multicast for crowdsourced live video providers. We propose a Virtual Network Function (VNF) service that identifies potential multicast scenarios based on user requests for a live video within a confined area. The VNF Application Server collects information, validates a potential multicast scenario, and initiates an ad-hoc multicast service on the fly. We use a real-world dataset of Facebook Live videos to evaluate the proposed architecture. The simulation results depict considerable advantages in terms of cost, efficiency, and Quality of Experience (QoE). Our results show that the proposed architecture provides significant benefits in bandwidth saving at the backhaul, transit, and RAN links.

An effective service-oriented networking management architecture for 5G-enabled internet of things

The development of a 5G-enabled Internet of Things has led to a dramatic increase in network traffic load, which has presented tremendous challenges to network management. In this paper, a service-oriented network architecture is proposed to support the effective management of 5G-enabled IoT systems. This architecture effectively reduces the traffic load and simplifies network management by introducing a service aggregation and caching (SAaC) scheme. Specifically, SAaC first breaks through the data-centric network architecture by converting data into services. Then, SAaC significantly reduces traffic load and energy consumption by service aggregation. Finally, SAaC introduces service caching, and each content router caches new services locally after aggregating received services so that user requests are handled at the network layer. Experimental results demonstrate that compared with traditional solutions, the SAaC scheme improves the request response time by 20.52%–56.09%, reduces the traffic load by 10.85%–37.67%, and reduces energy consumption by more than 50%.

Investigation of security issues for service-oriented network architecture

Investigation of security issues for service-oriented network architecture

Understanding and mitigating security and authentication issues in service oriented network architecture

Service oriented network architecture SONATE is one of the outcome of many architectures being explored to evolve as future network architecture. The architecture describes about the importance of flexibility to solve the short term as well as the long term requirements of the consumer Manu et al., 2012; Rudra et al., 2011a. Flexibility is the solution for solving the architectural problems but raises many security problems. It is important to consider security must be considered as the integral part of design level rather than at the development stage of the architecture. This paper discusses various security requirements for the entities of the architecture and the importance of authentication. A public key based infrastructure PKI mechanism is proposed and discussed in detail.

Exploration of access control mechanisms for service-oriented network architecture

The future network is expected to hosts much more than today's applications in an efficient manner but many flaws were found due to rigidity of the architecture. The researchers successfully developed many new flexible internet architectures to solve the infrastructural problems of the current internet. Service-oriented network architecture SONATE is one, which helps in supporting not only short-term demands but allows long-term demands that evolve. It offers various flexible services which bestow many issues of security. It is also envisioned that the security aspect needs to be embedded in the architecture because the major bottleneck in today's networking architecture is imparting the security provisions from outside the architecture. The authors discuss the need and importance for the development of access controls for the authenticated principals using a technique which is based on the role-based access and mandatory access for the loosely coupled nature of the services.

Service-oriented network architecture: significant issues and principles of communication

The internet is not designed for any specific application purposes, rather it is for generic and evolve purposes. Although the architecture of the internet is based on a number of principles including self-describing, datagram packet, the end-to-end argument, diversity in technology, and global addressing, but David D. Clark along with J.H. Saltzer highlighted end-to-end arguments amongst the most influential of all the communication protocol design goals. Also that internet adopted a method of patchwork approach to cope with the needs of evolution and revolution of technology growth with acceptable cost and speed. The future network is expected to host much more than today's applications in an efficient manner but experts predicted rigidity as one of the failure factors for current internet CI. In this paper the authors discuss various issues involved in the flexible network architecture - SONATE Reuther and Henric, 2008 while incorporating security functionality 'inside' the architecture.

Flexible Service Oriented Network Architecture for Wireless Sensor Networks

Wireless Sensor Network (WSN) is a combination of homogeneous and heterogeneous sensor nodes which are physically deployed at different places. Heterogeneous WSM can be characterized with different parameters such as hardware resources, application, services, software platform and network. WSN are powerful technology, which is used to build up many applications in the era of technological development. These developments demand homogeneous or heterogeneous services as per the user requirements at applications level. The requirement results in increasing the number of services over the network and hence the number of complexities. Complexities of wireless sensor networks are increasing due to the lack of adoption of new services, new protocols and interoperability between heterogeneous services with common communication architecture. This paper deals with these issues of wireless sensor networks, elaborating the need of generalized communication architecture for applications, developers and users, proposing generalized Flexible Service Oriented Network Architecture (FSONA) to solve above issues along with the detailed functionality of the proposed architecture.

Providing personalized converged services based on flexible network reconfiguration

Recent developments show a progressing convergence of networks, services, and applications, which results in the necessity for new approaches to provide a ubiquitous experience on converged networks for specialized high data-rate services. A fundamental diversifying attribute for the future physical network convergence paradigm is pressing. In this paper, we make researches on converged resource reconfiguration model of substrate physical network based on hardware virtualization and provide a service oriented network architecture as a network convergence primitive. Based on the idea of hardware virtualization which is performed by platform deformation and component processing with reconfiguration (here, they are realized as reconfigurable routers (RR)), the substrate converged network, which inter-connects various access networks by reconfigurable routers, could be mapped into multiplex service oriented logical networks, supports dynamic reconfiguration due to diversified quality of services under heterogeneous environment, and therefore provides more flexible and high-speed multiple services. In addition, to demonstrate the generality of our model, we provide a prototype of reconfigurable router. The design, implementation and task scheduling as well as both hardware and software reconfiguration process of reconfigurable router are discussed in detail. Our evaluation shows that reconfigurable router is transparent for upper service-providing networks and results in little performance impact on the service delivery when both hardware and software reconfiguration are used.

Service-Oriented Multigranular Optical Network Architecture for Clouds

This paper presents a novel service-oriented network architecture to bridge the informational gap between user applications and optical networks providing technology-agnostic multigranular optical network services for clouds. A mediation layer (service plane) between user applications and network control is proposed to facilitate a mapping process between user application requests and the network services. At the network level, a multigranular optical network (MGON) is proposed and implemented to support dynamic wavelength and subwavelength granularities with different transport formats [optical burst switched (OBS), optical burst transport (OBT)], reservation protocols (one-way, two-way), and different quality-of-service (QoS) levels per service type. The service-oriented multigranular optical network has been designed, implemented, and demonstrated on an experimental testbed. The testbed consists of service and network resource provisioning, service abstraction, and network resource virtualization. The service-to-network interoperation is provided by means of a gateway that maps service requests to technology-specific parameters and a common signaling channel for both service and network resource provisioning.
