A gas producer in the U.S. was creating five new facilities
and needed completely modular skids that could be easily
interchanged if necessary without impacting production.
Enerflex, an OEM skid builder, developed a new solution that on
seamless network connectivity via Allen-Bradley® Stratix® devices.
IntelliCENTER® software for motor control centers provides real-
time visibility into skid pressure, temperature, level, faults and
more. The producer can now use any skid where it’s needed most
and review skid performance to improve decision making.
Inter-controller Traffic in ONOS Clusters for SDN Networks Paolo Giaccone
In distributed SDN architectures, the network is controlled by a cluster of multiple controllers. This distributed ap- proach permits to meet the scalability and reliability requirements of large operational networks. Despite that, a logical centralized view of the network state should be guaranteed, enabling the simple development of network applications. Achieving a consis- tent network state requires a consensus protocol, which generates control traffic among the controllers whose timely delivery is crucial for network performance.
We focus on the state-of-art ONOS controller, designed to scale to large networks, based on a cluster of self-coordinating controllers, and concentrate on the inter-controller control traffic. Based on real traffic measurements, we develop a model to quan- tify the traffic exchanged among the controllers, which depends on the topology of the controlled network. This model is useful to design and dimension the control network interconnecting the controllers.
The Role of Inter-Controller Traffic in SDN Controllers PlacementPaolo Giaccone
We consider a distributed Software Defined Net- working (SDN) architecture adopting a cluster of multiple controllers to improve network performance and reliability. Differently from previous work, we focus on the control traffic exchanged among the controllers, in addition to the Openflow control traffic exchanged between controllers and switches. We develop an analytical model to estimate the reaction time per- ceived at the switches due to the inter-controller communications, based on the data-ownership model adopted in the cluster. We advocate a careful placement of the controllers, taking into account the two above kinds of control traffic. We evaluate, for some real ISP network topologies, the possible delay tradeoffs for the controllers placement problem.

Mobile network operators usually use internal macros and excel sheets to create scripts and xml files for bulk parameter changes and rehomes. With Accela Unified NMS Platform , it is easy, fast and accurate to create OSS/M2000/Netact scripts and to run from the module itself.
The ability to synchronise security equipment is becoming ever more important. This is not only for ensuring consistency, but also for evidential purposes.
Computer Networking meets Social PsychologyWaldir Moreira
An attempt to show what happens when computer networking, more specifically opportunistic networking, meets the social psychology discipline.

HAProxyconf 2019 - Criteo - Transitioning from Ticketing to LBaaSpierrecdn -
At Criteo, we work at the cutting edge of commerce marketing.
On the infrastructure side, we run tens of thousands of servers, host containers that continuously move across data centers, and scale services through our managed APIs, with HAProxy playing a critical role across our fast-paced, event-driven infrastructure. This presentation describe our journey to achieve load balancing served via a user-centric API in such a large and complex environment. We share tricks and design considerations that helped us to go from a user intent expressed through an API to a scalable service running globally.
Project implements a complex intra-networking system of various devices and modules working on IPv4 and IPv6 protocols providing various services like DNS, DHCP, HTTP, FTP, and SMTP. Information is routed among various client on the network with the use of protocols RIP, IMAP and OSPF. Project comprises of sub-netting, LAN switching and VLAN techniques to manage the number of hosts present in the network communicating with least network collision and congestion.
This presentation by Westermo’s Technical Lead Engineers Dakota Diehl and Benjamin Campbell, is an integral part of the Westermo webinar held on April 30th 2020, covering how to simplify your network management using Westermo software tools WeConnect and WeConfig.

CE1009_Implementation of Civil IoT Architecture.pdfChenkai Sun
Billions of interconnected Internet-of-Things (IoT) devices collect huge amounts of real-time data. However, this massive stream of data presents technical challenges for processing and analysis and the digital gap between urban and rural areas is also a critical consideration. A powerful platform is crucial to cost-effectively and efficiently process such massive collections of messages. This work introduces the civil IoT architecture in Taiwan including the dedicated B20 spectrum, backbone network facilities, and a scalable data platform. The proposed system operates in Taiwan for IoT applications with real cases. In the experiment, we demonstrate the performance of signal coverage, throughput, real-time query and visualization, and a monitoring mechanism. The results showed that the presented architecture is efficient and effective for dealing with IoT scenarios in a cost-effective approach.
