The document proposes a model for dynamically organizing edge computing nodes into micro clouds to provide edge computing as a service. The model involves grouping nodes into clusters, clusters into regions, and regions into a topology. Micro clouds are ephemeral cloud-like structures serving local requests before reaching the traditional cloud. Protocols for health checking, cluster formation, and listing the system state are proposed. The model is inspired by cloud architecture and aims to lower latency by processing data closer to its source.

This document provides an overview of IPv6 for an audience unfamiliar with the topic. It begins with a brief explanation of what IPv6 is and how it differs from IPv4 in areas like addressing and configuration. Statistics on global and domestic IPv6 deployment levels are presented. Potential business drivers for IPv6 adoption in research and education are outlined. The document then discusses IPv6 support and services available through Janet, as well as initial deployment strategies and considerations. Sources of additional guidance are listed, and examples of IPv6 in use are briefly described.

Slides of a seminar talk by Prof. Raj Jain to AT&T SDN Forum, April 10, 2014. It is well known that software defined networking and network function virtualization are key to the future of carriers. What may not be well known is the contentious debate among the industry leaders on approaches to these. In this talk, both sides of these arguments will be presented followed by an extension to the NFV idea that should be of interest to carriers. The second part of the talk describes our current research in the area of service chaining of globally distributed VNFs. In this presentation we describe OpenADN (Open Application Delivery Network) which allows multiple providers to chain both application-level and network-level services via VNFs distributed globally on several private/public clouds. This is similar to the "Cloud of Clouds" idea currently developing in the industry. There is immense opportunity for carriers to play the key role in this space.

NFV Use Case_Virtual Network Function As Service

Abdul Ravoof

This document discusses several network functions virtualization (NFV) use cases. It begins with an overview of NFV, which aims to consolidate network equipment types onto standard servers and switches. This provides benefits like rapid service innovation, improved efficiencies, reduced power usage, and greater flexibility. Specific use cases covered include virtualizing mobile core networks, base stations, CDNs, and home environments. It also discusses providing virtual network functions as a service (VNFaaS) and virtualizing network infrastructure as a service. For VNFaaS, it describes virtualizing enterprise customer premise equipment and provider edge routers as a service provided by the network operator.

Akshay Hegde

The document discusses architectural description based overlay networks. It proposes using architectural description documents that define the roles and relationships of nodes in an overlay network. These documents allow heterogeneous networks to work collaboratively by dynamically changing the roles nodes play and integrating multiple overlay networks. Nodes can switch between different overlays by exchanging and executing architectural description documents.

Lecture - Network Technologies: Peer-to-Peer Networks

James Salter

This document discusses different types of peer-to-peer network architectures including client-server, pure peer-to-peer, and hybrid peer-to-peer. It describes key characteristics of peer-to-peer networks such as nodes acting as both clients and servers, a lack of centralized control, and dynamic membership. Examples of early peer-to-peer systems like Napster and Gnutella are provided along with structured peer-to-peer approaches like Chord and BitTorrent. Research areas related to peer-to-peer networks like resource discovery, efficiency, robustness, incentives, and security are also summarized.

Lessons learned so far in operationalizing NFV

James Crawshaw

The document discusses lessons learned from operationalizing network functions virtualization (NFV). Some of the key challenges discussed include: 1) Integrating virtualized network functions (VNFs) introduces additional operational complexity for network operators. 2) Onboarding and testing new VNFs is challenging due to the large number of VNFs being introduced from different vendors. 3) Bridging the gaps between IT operations of the NFVI and network operations of the VNFs is an ongoing challenge. 4) Adopting agile development practices like DevOps is important for rapid development, certification, and deployment of NFV/SDN technologies but remains a challenge.

The document discusses network function virtualization (NFV) and its benefits, challenges, and use cases. NFV aims to implement network functions through software running on commercial off-the-shelf servers and storage, to provide benefits like reduced costs, increased agility, and flexibility compared to proprietary hardware appliances. The ETSI NFV Industry Specification Group is working on requirements and an architecture for NFV. Examples of potential applications include virtualized routers, firewalls, traffic monitoring functions and mobile network nodes. Both NFV and SDN aim to make networks more programmable and automated but through different approaches.

Network Function Virtualization Orchestration LI

Krishnamoorthy Arvind

Network functions virtualization (NFV) decouples network functions from proprietary hardware appliances and implements them as software virtual network functions (VNFs) that run on standard commercial off-the-shelf (COTS) servers. This allows network functions to be consolidated on shared hardware and provides benefits such as reduced costs, increased flexibility and service agility, and faster innovation. The European Telecommunications Standards Institute (ETSI) is developing open standards for NFV. Orchestration is a key enabling technology that manages the lifecycle of VNFs and coordinates their placement with physical network resources to automate service provisioning.

The Impact of Software-based Virtual Network in the Public Cloud

Chunghan Lee

Today’s cloud network consists of sophisticated virtual networks, and a virtual switch is a key element of these networks. Although there is tremendous interest in measuring cloud network performance, little is known about the impact of software-based virtual network on latency. In this paper, we conduct the impact of virtual network on latency in the public cloud based on OpenStack. We measured the throughput of VMs and simultaneously captured their packets on hosts. We analyzed the traces by using well-known metrics, such as throughput and RTT, and investigated the abrupt fluctuation of latency called as ‘the burstiness of latency’. We quantitatively clarify the impact of software-based virtual network on latency. In our public cloud, the latency is approximately 35.2% of RTT and 10% of burstiness mainly contributes to the increased RTT. The total latency was increased by the receiving side regardless of data and ACK paths. Our analysis results, discussions, and implications can not only help cloud researchers and developers design the next generation of software-based virtual network but can also help cloud operators improve the performance of virtual network.

This document summarizes a thesis on developing a distributed architecture for web browsing troubleshooting. The architecture integrates network measurement and analysis techniques through real-time data sharing across peers. It applies a dynamic distributed K-means clustering algorithm to partition browsing data from different locations into clusters representing performance issues. Experiments using the architecture identified local and non-local network problems affecting different peers. Future work could include testing with more peers, optimizing resource usage, and developing a user-friendly interface.

Enabling Traffic Management without DPI

NFV

SharathChandra Reddy Mandadi

NFV is an initiative to virtualize network functions that were previously carried out by dedicated hardware. Alten Calsoft is a pioneer in the NFV space since 2012 and is a member of ETSI NFV ISG. NFV works by decoupling network functions like routers, firewalls, and load balancers from dedicated hardware devices and running them as virtual machines on commercial off-the-shelf servers. A hypervisor manages the virtual machines and allows multiple operating systems to share a single hardware processor or host. Virtual machines can imitate multiple virtual hardware platforms in an isolated manner and enable operating systems like Linux or Windows server to run on the same physical host, saving costs by reducing physical hardware systems.

Multiprotocol label switching (mpls) - Networkshop44

Jisc

MPLS enables packets to be forwarded based on labels rather than IP addresses. PE routers add labels to incoming packets and remove labels from outgoing packets. P routers swap or pop labels to forward packets. MPLS with L3 VPN allows private networks in different locations to communicate securely over a shared infrastructure by associating routes with virtual routing instances (VRFs) and advertising them using BGP. An example configuration shows VRF and BGP configuration, along with commands to view MPLS label bindings and packet forwarding information.

Agile analysis development

setitesuk

This document describes the development of an agile analysis pipeline for processing next generation DNA sequencing data. The pipeline was developed iteratively using short 2-3 week iterations. Early iterations involved replacing sections of the pipeline with new pluggable components. Later iterations focused on refactoring the code and adding new features like automated quality control checks. A key iteration involved quickly fixing the pipeline when new analysis code introduced bugs. The agile development approach helped allow the priority to change to the critical fix and incorporate it with minimal disruption.

BPF began as an instruction set for filtering network packets over 30 years ago. In 2011, a startup sought to virtualize networking and build software-defined networks using a technology called iovisor. This led to challenges around crashing kernels and security issues. To address these, the startup developed a new instruction set called extended BPF and a verifier. Getting this technology accepted upstream required building reputation in the kernel and LLVM communities over several years by addressing concerns, making ideas familiar, and demonstrating performance benefits before the first patches were accepted in 2014-2015.

Flavius Ștef: Big Rewrites Without Big Risks at I T.A.K.E. Unconference

Mozaic Works

This document discusses strategies for incrementally rewriting software architecture without big risks. It suggests splitting large rewrites into smaller chunks and using techniques like faking functionality until it is implemented, incremental refactoring, and rewriting in small bites. Specific strategies discussed include researching prerequisites, creating proofs of concept, adding unit and performance tests incrementally, and removing dependencies one by one. Choosing the right refactoring is important, and catalogues of refactorings can provide guidance. An incremental process of analyzing, planning, refactoring, testing and integrating changes in small batches is recommended to validate progress toward goals at each step.

Python testing like a pro by Keith Yang

PYCON MY PLT

This document provides an overview of software testing strategies and tools for Python projects. It recommends: 1. Using tools like IPython, linters, yapf, pytest, and hypothesis to find errors early through static and dynamic testing. This allows issues to be identified and addressed before deployment. 2. Enabling easy debugging in production with tools like Sentry, IPython, and alog to monitor and diagnose runtime errors. 3. Preparing for failures through defensive programming techniques and testing backup plans, as "no tested backup plan equals no backup." Thorough testing during development helps maximize uptime and minimize surprises once software is deployed.

OS for AI: Elastic Microservices & the Next Gen of ML

Nordic APIs

AI has been a hot topic lately, with advances being made constantly in what is possible, there has not been as much discussion of the infrastructure and scaling challenges that come with it. How do you support dozens of different languages and frameworks, and make them interoperate invisibly? How do you scale to run abstract code from thousands of different developers, simultaneously and elastically, while maintaining less than 15ms of overhead? At Algorithmia, we’ve built, deployed, and scaled thousands of algorithms and machine learning models, using every kind of framework (from scikit-learn to tensorflow). We’ve seen many of the challenges faced in this area, and in this talk I’ll share some insights into the problems you’re likely to face, and how to approach solving them. In brief, we’ll examine the need for, and implementations of, a complete “Operating System for AI” – a common interface for different algorithms to be used and combined, and a general architecture for serverless machine learning which is discoverable, versioned, scalable and sharable.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP

RAHUL

This Dissertation explores the particular circumstances of Mirzapur, a region located in the core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal environment for investigating the changes in vegetation cover dynamics. Our study utilizes advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to analyze the transformations that have taken place over the course of a decade. The complex relationship between human activities and the environment has been the focus of extensive research and worry. As the global community grapples with swift urbanization, population expansion, and economic progress, the effects on natural ecosystems are becoming more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for these activities. As the most crucial natural resource, its utilization by humans results in different 'Land uses,' which are determined by both human activities and the physical characteristics of the land. The utilization of land is impacted by human needs and environmental factors. In countries like India, rapid population growth and the emphasis on extensive resource exploitation can lead to significant land degradation, adversely affecting the region's land cover. Therefore, human intervention has significantly influenced land use patterns over many centuries, evolving its structure over time and space. In the present era, these changes have accelerated due to factors such as agriculture and urbanization. Information regarding land use and cover is essential for various planning and management tasks related to the Earth's surface, providing crucial environmental data for scientific, resource management, policy purposes, and diverse human activities. Accurate understanding of land use and cover is imperative for the development planning of any area. Consequently, a wide range of professionals, including earth system scientists, land and water managers, and urban planners, are interested in obtaining data on land use and cover changes, conversion trends, and other related patterns. The spatial dimensions of land use and cover support policymakers and scientists in making well-informed decisions, as alterations in these patterns indicate shifts in economic and social conditions. Monitoring such changes with the help of Advanced technologies like Remote Sensing and Geographic Information Systems is crucial for coordinated efforts across different administrative levels. Advanced technologies like Remote Sensing and Geographic Information Systems 9 Changes in vegetation cover refer to variations in the distribution, composition, and overall structure of plant communities across different temporal and spatial scales. These changes can occur natural.
