Network is Reliable
•
0 likes•4 views
This presentation discusses the fallacy that "the network is inherently reliable" in distributed systems. It begins by defining distributed systems as collections of autonomous computers interconnected via a network that work together to accomplish shared objectives. While indispensable for scalability, fault tolerance, and efficiency, the geographical dispersion introduces challenges to network reliability. The core fallacy is the erroneous belief that network communication is always dependable. In reality, networks are subject to hardware failures, software errors, congestion, security threats, and a dynamic nature. The presentation advocates for resilience over reliability by designing systems that can withstand and adapt to failures, including network disruptions. Real-world examples like the 2017 AWS S3 outage and 2016 Dyn DDoS attack highlight the need

Performance, fault tolerance and scalability analysis of virtual infrastructu...www.pixelsolutionbd.com
This document analyzes the performance, fault-tolerance, and scalability of virtual infrastructure management systems with three typical structures: centralized, hierarchical, and peer-to-peer. It defines metrics for evaluating these properties and provides a quantitative analysis of each structure. The analysis finds that centralized structures have the lowest performance due to a single point of failure, while hierarchical and peer-to-peer structures demonstrate better fault-tolerance and scalability by distributing management responsibilities across multiple nodes.Secure final
The document discusses security mechanisms for spontaneous networks. It begins with an overview of the growth of mobile communications and challenges in configuring services and providing security in spontaneous networks that imitate human relationships. Key management schemes are needed for node authorization and user authentication in mobile ad hoc networks. Existing methods require initial configuration or external authorities. The proposed system aims to reduce dependence on a central authority for re-authentication to avoid possible attacks, increase performance by reducing server utilization, and implement a workload mechanism for efficient server usage.

CSEC630 individaul assign
This document discusses three methods of software assurance: kernel separation, desktop virtualization, and the Trusted Platform Module (TPM).
Kernel separation (also known as MILS) isolates operating system processes and partitions hardware to separate developer code, system resources, and data objects. This aims to reduce vulnerabilities by compartmentalizing different functions.
Desktop virtualization stores the desktop environment on centralized servers rather than individual devices. This allows for easier maintenance, troubleshooting, and access controls. All user data and customizations can be removed when logging off.
TPMs create encryption keys during the boot process to validate that critical software and firmware have not been modified. This helps detect malware early and takes a proactive approach to
Cloud computing
This document provides an overview of cloud computing, including what it is, computing needs it fulfills, perspectives on cloud architecture and types of clouds, drivers and barriers to adoption, and examples of top cloud computing providers. The key points made are that cloud computing provides dynamism, abstraction, and resource sharing; examples include Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS) models; and factors driving adoption include availability, collaboration, and scalability while barriers include security, reliability and vendor lock-in.
Advantages-and-Disadvantages-of-P2P-Network-Client-Server-Network.pdf
Peer-to-peer networks allow computers to share files and resources directly with each other without needing to go through a central server. In a peer-to-peer network, if one computer fails it does not disrupt the whole system. However, peer-to-peer networks provide less security and organization than client-server networks. Client-server networks use a central server computer to store and organize files, providing more security but creating single points of failure and potential bottlenecks if overburdened. Both network types have advantages and disadvantages related to decentralization, security, performance and maintenance.
Never Compromise Your Mission: 5 Ways to Strengthen Data and Network Security...
To learn more visit: http://www.unisys.com/stealth
For years, security involved layering perimeter defenses and physical technology infrastructure that drove up operations and IT costs. But advanced, innovative technologies are driving public sector leaders to step outside the conventional Band-Aid approach. A new breed of public sector security opportunities around software-defined networking has emerged – one that strengthens security and cuts costs. The key – hide all endpoints completely from attackers so there’s no vector to target. There are five ways public sector leaders can increase security and decrease costs:
Cloak your endpoints and go undetectable;
Segment your data center by using communities of interest;
Isolate disparate networks;
Move mission-critical workloads to a more secure cloud;
Convert existing computing devices into secure communications tools.
A framework forselfmanagemented
This document proposes an architecture for a framework of autonomic computing applied to hybrid wireless networks. The key points are:
1) Autonomic computing principles of self-configuration, self-optimization, self-healing, and self-protection are applied to enable self-management in hybrid wireless networks.
2) An architecture is proposed with autonomic elements distributed at different layers (e.g. routing, MAC) of the network that can monitor, analyze, plan and execute based on policies.
3) Artificial intelligence techniques like neural networks and fuzzy logic are identified as promising approaches to facilitate autonomic operations for functions like routing and radio resource management.

This document discusses using the Keyless Signature Infrastructure (KSI) to secure Software Defined Networks (SDNs). SDNs centralize network control, which improves agility but also creates new security risks if the centralized control plane is compromised. KSI can help address these risks by cryptographically signing SDN configuration data and network policies. This allows any SDN component to independently verify that it is using untampered data, without requiring trust in the SDN controller. KSI signatures provide real-time detection of any unauthorized data changes. By integrating KSI, SDNs can assure the integrity of critical network control data and detect insider threats or data manipulation attempts.
.Net projects 2011 by core ieeeprojects.com
The document contains summaries of 15 IEEE projects from 2011. Each project summary is 1-3 sentences describing the high level goal or problem addressed by the project. For example, one project proposes a policy enforcing mechanism to ensure fair communication in mobile ad hoc networks by regulating applications through proper communication policies. Another project presents a query formulation language called MashQL to easily query and fuse structured data from multiple sources on the web.
Novel secure communication protocol basepaper
This document proposes a secure communication protocol (SCP) for ad hoc networks using clustering techniques and Kerberos authentication. Key points:
M = {Nid, Knch, CHid}
- The network is divided into clusters, each with a cluster head (CH) node responsible for authentication.
Is encrypted by using public key of new node
Kun and send to new node. The new node
decrypts the message and stores Nid, Knch, CHid
information. Now the new node is authenticated
node of that cluster. The CH updates its
database with new node information.
- CHs use Kerberos authentication to generate IDs and passwords for nodes to authenticate each
SDN in Banking
Software-Defined Networks (SDN) could provide benefits to the banking and finance industry by increasing flexibility, security, and cost savings. SDN allows for centralized control of multi-vendor network equipment and easier configuration changes. This flexibility would help banks adapt their networks more easily to expansions and modifications. SDN could also reduce costs for banks compared to relying on proprietary hardware from individual vendors.

Chapter1 introductiontoscalingnetworks
The document discusses strategies for designing scalable enterprise networks. It recommends implementing a hierarchical network design with separate access, distribution, and core layers to limit failure domains. The core layer provides high-speed connectivity between distribution layers and remote sites. Modular, expandable equipment should be used to allow scaling without major upgrades. Careful IP addressing and redundant links also help networks scale effectively.

This document proposes a protocol for trilateral authentication in ad-hoc networks using multicast conventions. It introduces a central authority that manages key authentication and certification to increase security and reliability. Nodes are grouped into clusters, each with a cluster head. For similar clusters, authentication uses time asymmetry based on TESLA. For cross-cluster traffic, it uses secret information asymmetry where the source sends packets to cluster heads, which relay to members. Evaluation shows the central authority uses less memory than previous methods and the protocol has higher efficiency.

An approach of software engineering through middleware
The document discusses middleware and its role in facilitating the construction of distributed systems. It outlines some of the key challenges in building distributed systems, such as network communication, coordination between distributed components, reliability, scalability, and heterogeneity. Middleware aims to address these challenges by providing high-level abstractions and services that conceal low-level complexities related to distribution from application developers. The document argues that middleware is important for simplifying distributed system construction and should be a key consideration in software engineering research on distributed systems.

Kafka Summit talk (Bangalore, India, May 2, 2024, https://events.bizzabo.com/573863/agenda/session/1300469 )
Many Apache Kafka use cases take advantage of Kafka’s ability to integrate multiple heterogeneous systems for stream processing and real-time machine learning scenarios. But Kafka also exists in a rich ecosystem of related but complementary stream processing technologies and tools, particularly from the open-source community. In this talk, we’ll take you on a tour of a selection of complementary tools that can make Kafka even more powerful. We’ll focus on tools for stream processing and querying, streaming machine learning, stream visibility and observation, stream meta-data, stream visualisation, stream development including testing and the use of Generative AI and LLMs, and stream performance and scalability. By the end you will have a good idea of the types of Kafka “superhero” tools that exist, which are my favourites (and what superpowers they have), and how they combine to save your Kafka applications development universe from swamploads of data stagnation monsters!

- 3. Introduction Distributed computing systems are foundational in modern technology, facilitating the scalability and robustness of applications. These systems consist of multiple interconnected nodes, communicating over a network. However, a prevailing misconception in distributed computing is the fallacy that "The Network is Inherently Reliable."
- 4. What Are Distributed Systems? Distributed systems are collections of autonomous computers interconnected via a network, working together to accomplish shared objectives. They are indispensable for scalability, fault tolerance, and efficient resource utilization. Nonetheless, the geographical dispersion of components introduces challenges related to network reliability.
- 5. The Fallacy - "The Network is Inherently Reliable" The misconception revolves around the erroneous belief that network communication between distributed components is invariably dependable. Succumbing to this misconception can result in suboptimal system designs and unforeseen failures.
- 6. Why Is This a Fallacy? Hardware Failures Network Congestion Dynamic Nature This fallacy persists due to various factors: Software Errors Security Threats
- 7. Resilience vs. Reliability Instead of blindly relying on network reliability, it is effective to set goals for flexibility, which involves designing systems that withstand and adapt to failures, including network disruptions.
- 8. Real-World Examples The 2017 Amazon Web Services (AWS) S3 outage. The 2016 Dyn Distributed Denial of Service (DDoS) attack. Blockchain Example - 51% Attack Real-world cases highlight the significance of mitigating this misconception:
