Service-oriented network (SON) is a promising way to realize heterogeneous networking and Cloud computing system integration, because SON enables a Network-as-a-Service (NaaS) paradigm and provides a general interface by which every service participant is able to communicate and cooperate, conveniently and transparently. However, QoS-aware service path construction is a crucial and inevitable problem...
The default cache strategy of Content Centric Networking(CCN) is storing at each Content Router (CR) along the deliver path. It is high cache redundancy which causes the performance of CCN degradation. Hence, finding an efficient caching mechanisms is necessary in CCN. We agree that the single attribute can not to adapt to the complex network environment. the MAC considers hop count or distance, node...
Cloud radio access network (C-RAN) opens up new opportunities to have a better resource management of mobile network on the basis of centralized processing. The fronthaul, which transfers signals between baseband units (BBUs) and remote radio units (RRUs), is confronted with bandwidth allocation problem when multimedia multicast technique is introduced. In this paper, we propose an algorithm using...
The popularity of big data has resulted in the pro-liferation of applications and services with a lot of conveniences in social networks. Unfortunately, the diverse data sets contain users' privacy-sensitive information, which brings about privacy concerns potentially if the information is released or shared to the service provider. The existing practical techniques for big data privacy protection...
Cache technology has emerged as a promising approach for distributed web systems to mitigate the web server's data access performance bottleneck. In this paper, we propose a decentralized load balancing architecture. The cache system takes advantage of the decentralized architecture for providing scalability and high availability. It can provide content requested by a user if it is cached in any of...
The over 40-year old Internet, which was designed and proposed with the intention to interconnect several computing resources across a geographically distributed user group, is now facing many unprecedented challenges especially from the increasingly abundant demands in future networks. Traditional IP protocol can hardly deal with the challenges due to the single function and low QoS. In this paper,...
Though the decades of great success the Internet has experienced, it still confronts with many challenges to achieve QoS of various business types. A consensus has been reached that resource allocation presents a tremendously status in such a network bandwidth poor settings. In this paper, we bring the knapsack problem idea into reconfigurable network architecture (RNA), which is proposed with the...
With extensive promising applications, machine to machine (M2M) communications or machine-type communication (MTC) have attached a tremendous interest among mobile network operators and research groups. Supporting multiple MTC devices has been considered as an essential requirement in M2M communications. How to achieve a secure and efficient access authentication for a group of MTC devices during...
The big pressure of huge traffic requires people to consider how to improve the network efficiency. One of possible solutions is to reduce the traffic entering the metro/core networks. A flexible PON architecture based on software defined network technology is proposed to increase the exchange capability of local access network, which is comprised of an OLT pool, an ONU pool, a flexible ODN, and a...
Supporting a massive number of machine-type communication (MTC) devices has been considered as an essential requirement in machine to machine (M2M) communications. Meanwhile, cyber security is of paramount importance in MTC; if MTC devices cannot securely access the networks through efficient authentication, all applications involving MTC cannot be widely accepted. One of research challenges in MTC...
We demonstrate for the first time enhanced software defined networking (eSDN) over elastic grid (eGrid) optical networks for data center service migration, the performance of which are first verified on our testbed with real prototypes.
Cloud storage is one of the underlying services in cloud computing. However, there are some critical issues in file storage which should be resolved urgently, such as the blocking file storage. In order to solve the shortages of hot file storage and parallel computing support issues in fixed-blocking storage, we propose a smart-blocking file storage method in this paper. By setting up 6 grouping factors,...
After having studied Model Driven Architecture (MDA) and ATLAS transformation language (ATL), in this article, Platform Independent Model (PIM) module divides into multiple demand function PIM modules according to requirement analysis of system, and it generates corresponding demand function Platform Specific Model (PSM) modules with ATL receive model conversion signals, this paper establishes a framework...
Recently, a number of cloud computing paradigms have been proposed. The new term of cloud computing is not a new concept, is a long-held dream of computing as a utility [1]. From the view of datacenters, the common understanding of the cloud computing concept is Software as a Service (SaaS), utility computing and application virtualization. In the domain of Rich Internet Application (RIA) domain,...
Model Driven Architecture (MDA) is a development methodology taking model as center, it shift the focus of software development activity from coding to modeling, which is initiated by the Object Manage Group and based on UML and other standard etc. Aspect-Oriented Programming (AOP) is an emerging software engineering paradigm that improves separation of cross-cutting concerns as aspect in a program...
Tens, hundreds and even thousands of cores are to be integrated into a single chip. Network on chip appears to offer efficient communication between cores. However, the increased requirement for larger communication bandwidths and lower power consumption challenges the traditional electrical interconnects. Advances in silicon nanophotonics make optical interconnect a promising candidate for network...
On basis of the analysis of the architecture of MIS and GIS, the application of IoC pattern is introduced to resolve the problem of G2M integration (introducing embedded GIS into MIS), so that the key technology about G2M integration can be figured out, and the tightly coupled system which led by an inappropriate integration method can also be avoided. After expatiation of the integration principle,...
In intelligent inhabited environments (IIEs), the different user's preferences and needs are different, and the same user's preferences will change over time, which desire that the intelligent agents have evolvement function. In this paper, we propose a new fuzzy control system that is embedded in the intelligent agent which is a function agent in Multi-Agent System (MAS) based on ZigBee wireless...
In this paper, we propose a novel load-balanced scheme-split aggregated flow (SAF) and design the buffering mechanism for two-stage self-routing switch. By grouping the signal lines with concentrators, the proposed scheme can obtain the statistical multiplex gain and reduce the complexity of computation. The mathematical analysis and simulations show that 100% throughput can be achieved for any admissible...
Model-driven development (MDD) aims to shift the focus of software development activity from coding to modeling. However, managing relationships and specifying transformations between models at various levels of abstraction are complex tasks. System models tangled with concerns such as security make it difficult to develop complex systems and specify model transformations. Aspect-oriented programming...
