The Locator/Identifier Separation Protocol (LISP) separates classical IP addresses into two categories: one for identifying terminals, the other for routing. To associate identifiers and locators LISP needs a specific mechanism, called mapping system. This technology is still at an early stage but two experimental platforms have already been deployed in the Internet: LISP Beta Network and LISP-Lab...
With the continuous progress of rural construction, the problem of rural drinking water pollution is increasingly prominent. In view of water pollution, a design of rural drinking water monitoring system based on wireless sensor networks is proposed that nodes take STM32 as the core chip and WLK01L39 as well as its peripheral circuits are used as wireless communication modules and Beidou S1216 is...
In order to integrate a large number of distributed energy resources in distribution grids a robust decentralized information and communication control structure is required. This paper proposes an overlay peer-to-peer (P2P) architecture for controlling and monitoring microgrids in real time, which has a great capacity of adaptation to the demanding network requirements of these environments. The...
Network load-balancers generally either do not take application state into account, or do so at the cost of a centralized monitoring system. This paper introduces a load-balancer running exclusively within the IP forwarding plane, i.e. in an application protocol agnostic fashion - yet which still provides application-awareness and makes real-time, decentralized decisions. To that end, IPv6 Segment...
Content Delivery Networks (CDNs) are able to improve user-oriented application performance through caching and anycast routing or DNS-based user mapping mechanism. With the fact that BGP is widely used for inter autonomous system (AS) routing for CDNs, there is a middle mile bottleneck problem, which cause by the nature limitation of BGP. To solve this problem, we propose an SDN-based tunnel multi-path...
Micro-clouds infrastructures allow supporting applications on local and energy-efficient resources. Communication between micro-clouds takes place on shared and non-dedicated Internet links. Network control and optimization can only happen at the edge. For availability and persistence, the storage of application data must be geo-replicated. Maintaining strong data consistency under concurrent accesses...
Communication systems in today's world are no longer traditional in nature. Platforms required for Industry 4.0 that fall under Control and Monitoring systems, are datagathering units which gather data from remote devices and monitor them. Such platforms have various components which communicate with each other for data handling and monitoring. In the traditional peer-to-peer model, every module communicates...
Computer networks today typically do not provide any mechanisms to the users to learn, in a reliable manner, which paths have (and have not!) been taken by their packets. Rather, it seems inevitable that as soon as a packet leaves the network card, the user is forced to trust the network provider to forward the packets as expected or agreed upon. This can be undesirable, especially in the light of...
With the growth of the Cloud Computing paradigm, a new challenge appears in the development of data centers: energy efficient load balancing in a dynamic and scalable environment with an undefined number of heterogeneous resources. In this context, considering that idle servers consume up to 60% of peak energy and the fact that usually the level of usage for a server is 20–30%, new load balancing...
With rapid progress in information and communication technology (ICT), the existing communication infrastructure has been continually evolving. Telecommunication network operators may need to expand hardware and software infrastructure to adopt new communication technologies, which will require considerable capital investments. In addition, devices for Internet of Things (IoT) are being rapidly adopted...
The autonomous cache management in Content-Centric Networking (CCN) results in suboptimal caching decisions and implies cache-ignorant routing. Cache coordination and similar improvements hence have been the subject of several recent studies. The proposed solutions, however, are either impractical due to their massive coordination overhead, or of limited benefit since they cannot realize perfect coordination...
The cloud computing provides better management and utilization of underlying infrastructures with resource virtualization. However, most of existing load balance models are unable to meet the special requirements of business such as the imbalance of peak period, the impact of nonlinear cross between varieties of business. Thus the reliability, scalability and self-organization of service becomes a...
Rural digital connectivity in developing nations have failed to sustain themselves after subsidy is removed. The demography of users does not demand Internet connectivity for majority of their communication needs. This work proposes an extensible platform for rural communication utilizing delay tolerant networks. The platform allows quick development of localized applications for day to day communication...
Weighted round robin load balancing is a common routing policy offered in cloud load balancers. However, there is a lack of effective mechanisms to decide the weights assigned to each server to achieve an overall optimal revenue of the system. In this paper, we first experimentally explore the relation between probabilistic routing and weighted round robin load balancing policies. From the experiment...
Unlike the current Internet where applications have little control over the path that their data travels, emerging network architectures enable applications to control the path their packets/flows take. Although an application can select its paths, providing an application with the up-to-date information needed to make an informed decision is a difficult problem. In particular, monitoring (i.e., collecting...
Data availability is a major challenge faced by today's Data Centers where a large number of high performance servers are organized into racks interconnected by a switching network. Data replication is an effective approach for data protection as redundancy ensures at least one copy of data is available in the event of failures. To achieve low latency and high throughput for data replication operations,...
Despite the development of virtualization technologies in computing resources, how best to build virtual networks is still an open issue. Virtual network is an important technology that can hide physical network topologies and policies and provide a dedicated virtual computing environment for each user. However, it is difficult to figure out the actual mapping between a physical network and a virtual...
One of the most important aspects of a wireless health monitoring system is the security of data. In this paper, security attacks against the complete transmission chain of a medical health monitoring system are enumerated and classified based on their threat to three security principles: confidentiality, integrity and availability. The communication chain is divided in a standard way into three tiers...
Routing in overlay networks typically involves engineering an overlay topology on top of the Internet to balance traffic along overlay paths so that quality and/or resilience of delivered services are improved. It can be used to reduce latency for delay-sensitive applications. It then consists in selecting, for any pair of nodes, an intermediate overlay node which reduces the latency on this one-hop...
The Internet Autonomous System (AS) topology has important implications on end-to-end routing, network economics and security. Despite the significance of the AS topology research, it has not been possible to collect a complete map of the AS interconnections due to the difficulties involved in discovering peering links. The problem of topology incompleteness is amplified by the increasing popularity...
