The document discusses key concepts in networking including internetworking, encapsulation, synchronization, fragmentation, encryption, and protocols. Intenetworking is defined as connecting local area networks to create wide area networks and connecting wide area networks. Encapsulation involves adding header and data packets at each layer of the OSI model. Synchronization allows adding checkpoints to data streams. Fragmentation is the process of breaking packets into smaller pieces for transmission. Encryption transforms information during transmission to ensure privacy. Protocols are sets of rules that govern data communication.

Encapsulation

The above figure reveals another aspect of data communication in the OSI model:
encapsulation.

A packet ( header and data) at level 7 is encapsulated in a packet at level 6.

The whole packet at level 6 is encapsulated in a packet at level 5, and so on.

In other words, the data portion of a packet at level N-1 carries the whole packet from level N.
The concept is called encapsulation.

synchronization 

10 Department of Computer Science, RLJIT 5/23/2012

Synchronization

The session layer allows a process to add checkpoints , or synchronization points, to a stream
of data. For example, if a system is sending a file of 2000 pages, it is advisable to insert
checkpoints after every 100 pages to ensure that each 100-page unit is received and
acknowledged independently. In this case, if a crash happens during the transmission of page
523, the only pages that need to be resent after system recovery are pages 501 to 523. Pages
previous to 501 need not be resent.

Fragmentation
Fragmentation is the process of breaking a packet into smaller pieces. The receiving system

Encryption

To carry sensitive information, a system must be able to ensure
privacy. Encryption means that the sender transforms the original
information to another form and sends the resulting message out over
the network. Decryption reverses the original process to transform the
message back to its original form.

Grid computing & its applications

Alokeparna Choudhury

Traditionally, while creating our system, you don't focus on creating our components separated from each other. As a result, one problem can lead you to the domino effect - the whole system stops working. How to counteract it? "Loosely coupled architecture" is recognized as the main factor to create a highly-scalable system. It allows you to make changes in your application which won't effect on their other part. See yourself what are the criteria of this architecture to be able to introduce it to your solution from the very beginning.

Running Head: THE SEVEN LAYER MODEL OF OSIKao 1 THE SEVEN LAYER MODEL OF OSIKao 2 The Seven Layer Model of OSI Kao Badi Prudence CMIT 265 Professor: Ryan Thomas Date: 06/25/2020 The Seven Layer Model of OSIComment by Prof Thomas: Paper format changes between sections. Review format The Open System Interconnect (OSI) is a very important concept in networking when considering the creation of a a networking system for the university. “It was created by the international organization of standards 1978 and its main purpose is to help describe the architecture of a network so as make it possible for computers to send and receive data from other computers”. Although the model is conceptual, appreciating its purpose and function will help the university in understanding how the protocol suits and network architecture work on an application basis. The OSI model is usually built from bottom to top in this order; physical, data link, network, transport, session, presentation and lastly application. Every layer of the OSI model has its own special function. The following sections describe the function of each layer. The layers of the OSI model Physical Layer (Layer 1) The OSI model layer identifies the networks’ physical characteristics and specifications. This is the type of media used on the network for example type of connector, cables, and pinout format cables. Topology The topography is defined by the physical layer. This layer shows the type of topology to be applied in the network. Additional characteristics in this layer define voltage used on a given frequency and medium at which the signals that carrying the data operates. They dictate speed and bandwidth of a given medium and the maximum distance over which a specific media type can be applied Data link Layer (Layer 2) The layer is a designed protocol that operates in a program involved in data movement into and out of a physical link in a network. Layer 2 of the OSI model is responsible for receiving data for layer 1. It is then sent to layer 3 and the data from layer 3 is sent to layer 1. This layer also detects and corrects errors. The word ‘frame’ is usually used to refer to the logical data grouping at this layer. It has two distinctive sub-layers: · Access control (MAC) - MAC address is the physical/hardware address burnt into each network interface card (NIC). It accesses specific areas that are found within the interior of buildings. Provides access that is faster to the people authorized and restricts access of people not authorized. · Link control (LLC) – “this controls the error and flows control mechanism of the data link layer [2].” It plays the role of managing the transmissions of data to ensure that there is integrity. For NLC, it has a role of providing data link layers. · Network Layer (Layer 3). The primary faction of layer 3 is to giving access to the ways by which information can disseminate to and from different network systems. It does not specify.

There is no doubt that network coding is a promising enhancement of routing to improve network throughput and provide high reliability. However, there are several open problems in practical network coding, especially on how to guarantee coding advantage for a decentralized control network without the knowledge of the network topology. The biggest benefit of OpenFlow is to decouple the control plane from the data plane, allowing the centralized forwarding decisions in comparison to traditional distributed control network. As a result, we propose a Software-Defined coding network and address key technical challenges in practice. We design NC-OF, a framework to enable networking coding in SDN networks, and use MMF-NC coding strategy proposed by Guan Xu in NC-OF. Finally, we proved that our solutions can effectively improve network performance through simulation experiments. And we also find that network coding is not necessary when the link bandwidth is enough , because it will bring the problems of time delay, the increase in the amount of calculation and so on.

Executing large number of self-regulating tasks or tasks that execute minimal inter-task communication in analogous is a common requirement in many domains. In this paper, we present our knowledge in applying two new Microsoft technologies Dryad and Azure to three bioinformatics applications. We also contrast with traditional MPI and Apache Hadoop MapReduce completion in one example. The applications are an EST (Expressed Sequence Tag) series assembly program, PhyloD statistical package to recognize HLA-associated viral evolution, and a pairwise Alu gene alignment application. We give detailed presentation discussion on a 768 core Windows HPC Server cluster and an Azure cloud. All the applications start with a “doubly data parallel step” connecting independent data chosen from two parallel (EST, Alu) or two different databases (PhyloD). There are different structures for final stages in each application.

OpenFlow enabled networks split and separate the data and control planes of traditional networks. This design commodifies network switches and enables centralized control of the network. Control decisions are made by an OpenFlow controller, and locally cached by switches, as directed by controllers. Since controllers are not necessarily co-located with switches that can significantly impact the forwarding delay incurred by packets in switches. Only very few studies have been conducted to evaluate the performance of OpenFlow in terms of end-to-end delay. In this work we develop a stochastic model for the end to end delay in OpenFlow switches based on measurements made in Internetscale experiments performed on three different platforms, i.e. Mininet, the GENI testbed and the OF@TEIN testbed.

The research work focused on the future of the internet security transaction without allowing unauthorized user from accessing the secret document. The system was implemented with python flask framework been the lightest micro framework. The quantum key distribution generator model used is the BB84. Users can create account one the sender and other receiver then peered together in single communication channel. The sender attach file and send it in an encrypted manner to be received by receiver on presenting the same quantum key used for encrypting it. Once the eavesdropper click the link of the protocol, an alarm is raised and the system quantum key is change instantly and committed into the database. The other application is the Quantum Simulator, this application is used for generating a simulation for a quantum cryptography. Madubuezi Christian Okoronkwo | Onwuzo J. C | Gregory E.

Quantum Cryptography Approach for Resolving Cyber Threats

Empirical studies have revealed that a significant amount of energy is lost unnecessarily in the network architectures, protocols, routers and various other network devices. Thus there is a need for techniques to obtain green networking in the computer architecture which can lead to energy saving. Green networking is an emerging phenomenon in the computer industry because of its economic and environmental benefits. Saving energy leads to cost-cutting and lower emission of greenhouse gases which are apparently one of the major threats to the environment. ’Greening’ as the name suggests is the process of constructing network architecture in such a way so as to avoid unnecessary loss of power and energy due its various components and can be implemented using various techniques out of which four are mentioned in this review paper, namely Adaptive link rate (ALR), Dynamic Voltage and Frequency scaling(DVFS), Interface proxying and energy aware applications and software.

Tracing the root cause of a performance issue requires a lot of patience, experience, and focus. It’s so hard that we sometimes attempt to guess by trying out tentative fixes, but that usually results in frustration, messy code, and a considerable waste of time and money. This talk explains how to correctly zoom in on a performance bottleneck using three levels of profiling: distributed tracing, metrics, and method profiling. After we learn to read the JVM profiler output as a flame graph, we explore a series of bottlenecks typical for backend systems, like connection/thread pool starvation, invisible aspects, blocking code, hot CPU methods, lock contention, and Virtual Thread pinning, and we learn to trace them even if they occur in library code you are not familiar with. Attend this talk and prepare for the performance issues that will eventually hit any successful system.

Retrieval augmented generation (RAG) is the most popular style of large language model application to emerge from 2023. The most basic style of RAG works by vectorizing your data and injecting it into a vector database like Milvus for retrieval to augment the text output generated by an LLM. This is just the beginning. One of the ways that we can extend RAG, and extend AI, is through multilingual use cases. Typical RAG is done in English using embedding models that are trained in English. In this talk, we’ll explore how RAG could work in languages other than English. We’ll explore French, Chinese, and Polish.
