Network measurement is an important tool for network managers and operators since it provides the information needed to carry out different management tasks. However, because of the rapid increase in data link speeds and the volume of traffic carried by modern networks, the availability of system resources dedicated to network measurement has always been the main limiting factor in developing modern...
Multi-Processors Systems-on-Chip (MPSoCs), as a key technology enabler of the new computation paradigm Internet-of-Things (IoT), are exposed to attacks. Malicious applications can be downloaded at runtime to the MPSoC, infect IPs and open doors to perform timing attacks. By monitoring the Network-on-Chip (NoC) traffic, an attacker is able to spy sensitive information such as secret keys. Previous...
There are many costs associated with the building and running a telecommunications network, both capital (CAPEX) and operational (OPEX) costs. On the one hand, complex routing schemes activated in multi-layer networks, like MPLS, logically imply assignment of costs to a collection of modules, from more than one layer, so defining the cost model is a non-trivial task. On the other hand, optimization...
The specifications of OpenFlow switch define the fast failover1 group table, which allows the switch quickly adapt to failure based on its local states. In a failure scenario, the traffic on a faulty path is fast switched to a predetermined path in a so-called active/standby manner. That is likely the standard and only way of achieving fast switchover. In this paper, we introduce a novel method for...
NATO is transitioning from traditional circuit-switched networks to what is known as IP converged networks. There is a migration path towards an IP based network for all the services that currently are offered over circuit-switched communication services.
With an increasing trend to implement Network-on-Chip (NoC)-based Multi-Processor Systems-on-Chips (MPSoCs), NoCs need to have guaranteed services and be dynamically reconfigurable. Many current NoCs consume too much area and cannot support dynamic reconfiguration. In this paper, we present an area-efficient Spatial Division Multiplexing (SDM)-based NoC. We replaced area consuming 32-bit to M-bit...
In future, mobile multimedia services will become popular as widely as the use of the cellular phone today. It makes the bandwidth required for each multimedia service increase rapidly, and such kind of communication will be dominant since the development of machine-machine communications for human interactivity in the multimedia age. For this demand, the micro-cell will become a major role in substitution...
In the context of Run-time Resource Management (RRM), several research directions are ongoing. To allow exploration, integration, and efficient collaboration of all complementary techniques, this paper presents a generic and structured framework for RRM of embedded multi-core platforms, together with the most relevant services to be supported. The main focus of this RRM is the holistic view of platform...
Ensuring a seamless connection when users are moving across radio cells is essential to guarantee a high communication quality. In this paper, performance of TCP during the handover in a Long Term Evolution (LTE) network is investigated. Specifically, mobile users with high bit rates TCP services are considered, and the impacts of the intra LTE handover over their perceived throughput are studied...
Run-time partial reconfiguration (PR) speed is significant in applications especially when fast IP core switching is required. In this paper, we propose to use direct memory access (DMA), master (MST) burst, and a dedicated block RAM (BRAM) cache respectively to reduce the reconfiguration time. Based on the Xilinx PR technology and the Internal Configuration Access Port (ICAP) primitive in the FPGA...
Next-generation networks (NGNs) employ the Internet protocol (IP) over a wide variety of packet-switching technologies, which often lack in fault resilience enabling features. An overlay MPLS infrastructure with its fast-reroute mechanisms can be deployed to overcome such an issue. Addressing NGNs robust to single link and node failures, an offline method to effectively calculate working and recovery...
The basic DiffServ model lacks the mechanism to prevent itself from being overload; it does not have any capability to inform the edge nodes about the internal traffic load in the network. Thus, injecting more QoS sensitive traffic into the network will not only degrade the performance of the current flow but it will also degrade the performance of already established flows. In this research paper...
A pull operation-based network resource allocation architecture with application switching is proposed to apply QoS policy for non-SIP applications. Using the architecture, dynamic bandwidth allocation is successfully demonstrated for session-aware and non session-aware applications.
