Internet has become a foundation of our modern society. However, all regions or countries do not have the same Internet access regarding quality especially in the Indian Ocean Area (IOA). To improve this quality it is important to have a deep knowledge of the Internet physical and logical topology and associated performance. However, these knowledges are not shared by Internet service providers. In...
A rapid growth in the internet network technologies claims for a better routing protocol in transmitting data. The network performance is evaluated to compare the two Link State (LS) routing protocols which are the Open Shortest Path First version3 (OSPFv3) and Intermediate System to Intermediate System (IS-IS). The evaluation is done in terms of the performance in the network convergence through...
Convolutional neural networks (CNNs) are deployed in a wide range of image recognition, scene segmentation and object detection applications. Achieving state of the art accuracy in CNNs often results in large models and complex topologies that require significant compute resources to complete in a timely manner. Binarised neural networks (BNNs) have been proposed as an optimised variant of CNNs, which...
Network-on-Chip (NoC) is a nascent approach for reducing the communication bottleneck of multicore System-on-Chip (SoC). As the number of cores are increasing on SoC due to high performance demand of the consumer electronics and processing systems like servers, the low power and low latency NoC is required. Topologies are one of the most important parts of a NoC design, with considering the performance...
In the context of graph-based simultaneous localization and mapping, node pruning consists in removing a subset of nodes from the graph, while keeping the graph's information content as close as possible to the original. One often tackles this problem locally by isolating the Markov blanket sub-graph of a node, marginalizing this node and sparsifying the dense result. It means computing an approximation...
Cisco DevNet Always-On APIC-EM Sandbox is useful in the phase of learning about software-defined networking, allowing to perform experiments, but without the possibility to change the topology the extent of development is limited. In this paper a Cisco APIC-EM SDN Controller was installed in a private cloud orchestrated by OpenStack. The major objective was to create a virtualized testbed, consisting...
Server security is necessary to avoid all attack that will happen. IPS (Intrusion Prevention System) is an example of right solution for the security system. IPS can prevent an attack by using the IDS (Intrusion Detection System) and firewall features. In this paper, bro IPS on the server will be tested with some attack include DOS (Denial of Service), port scanning, and ftp brute force to ensure...
Other than merely a bandwidth pipe, current and future network applications will have other requirements such as maximum end-to-end latency and the type of recovery from failure. The added complexity will require a central intelligence such as a software-defined networking (SDN) orchestrator to compute and keep track of the resources allocated to such applications. In such an SDN-orchestrated network,...
Software Defined Networking is a new networking paradigm that has emerged recently as a promising solution for tackling the inflexibility of the classical IP networks. The centralized approach of SDN yields a broad area for intelligence to optimise the network at various levels. Fault tolerance is considered one of the most current research challenges that facing the SDN, hence, in this paper we introduce...
This paper proposes a cross-layer collaborative interconnecting approach for the multi-control domain SDON networks. It's able to optimize network resources and achieve the real-time response of the network state. We use this approach to handle the traffic in single control domain and multi-control domain, which optimize transmission of the large granular traffic and the small granular traffic in...
Information-Centric Networking (ICN) has emerged as an interesting approach to overcome many of the limitations of legacy IP-based networks. However, the drastic changes to legacy infrastructure required to realise an ICN have significantly hindered its adoption by network operators. As a result, alternative deployment strategies are investigated, with Software-Defined Networking (SDN) arising as...
Since the early 2000's, the Internet Topology has been frequently described and modeled from the perspective of routers. To this end, alias resolution mechanisms have been developed in order to aggregate all IP interfaces of a router, collected with traceroute, into a single identifier. So far, many active measurement techniques have been considered, often taking advantage of specific features from...
Distributed overlay-based publish/subscribe systems provide a selective, scalable, and decentralized approach to data dissemination. Due to the dynamic communication flows between data producers and consumers, the overlay topology of such systems can become inefficient over time and therefore requires adaptation to the existing load. Existing studies propose algorithms to design overlay topologies...
To speed up the recovery from network failures, an extensive list of methods have been proposed. Many failure-recovery methods are proposed based on tunneling or marking, which increase the packet processing burden on routers and consume extra bandwidth. With neither tunneling nor marking, existing methods guarantee recovery from any single-link failure if a detour for the failed link exists, but...
The topology of data centers changes dynamically due to link malpositions, hardware failures or software crushes. However, many topology enabled protocols or applications must know the current topology of data center precisely, which triggers the topology calibration problem. Topology calibration needs to deduce the different nodes and links between two given topologies effectively. Based on the existing...
A low-latency and reliable message switching network is critical for constructing high-speed datacenter networks. In this paper, we present the design, implementation, and evaluation of a novel Location basEd Source Switching (LESS) for datacenter networks. LESS enables lightweight source switching through a location-based addressing scheme. Each switch and host can independently derive a source route...
Information Centric Networking (ICN) is seen as a promising solution to re-conciliate the Internet usage with its core architecture. However, to be considered as a realistic alternative to IP, ICN must evolve from a pure academic proposition deployed in test environments to an operational solution in which security is assessed from the protocol design to its running implementation. Among ICN solutions,...
Bit Indexed Explicit Replication (BIER) is a novel multicast forwarding scheme for IP networks that avoids states in replicating routers by encoding the multicast information into a bit string in the packet header. In addition, the BIER-TE variant encodes the multicast tree in the header and allows for network programmability. We propose the use of maximally redundant trees (MRTs) for 1+1 protection...
The continuous increase in data traffic, heterogeneous access networks, and the diversity in the Quality of Service (QoS) requirements of the applications is expected to significantly increase the management complexity of 5G networks. Software Defined Networking provides an effective management architecture enabling more efficient utilization of 5G network resources. In this paper, a novel failure...
The chip industry faces two key challenges today — the impending end of Moore's Law and the rising costs of chip design and verification (millions of dollars today). Heterogeneous IPs — cores and domain-specific accelerators — are a promising answer to the first challenge, enabling performance and energy benefits no longer provided by technology scaling. IP-reuse with plug-and-play designs can help...
