This paper proposes a topology for local computer networks. Called "Dragnet", it is similar to the Ethernet network in function, but rather different in the following respects:1. Instead of a single long bidirectional cable, there are multiple short unidirectional cables.2.
A system that could classify DNS, Telnet, Ping, Voice, Game, and Video traffic flows based on packet and byte information simulated by the Distributed Internet Traffic Generator (D-ITG) tool in an Software Defined Network (SDN) based network topology with Open vSwitch (OVS) using machine learning algorithms such as Logistic regression,K-Means cl…
Jan 22, 2020 · From video monitoring, wire tapping, and license plate scanning to GPS tracking and digital communications surveillance, the methods governments use to keep close tabs on their citizens have increased in scope and sophistication over the past decades.

Layer 1 is the physical layer. There’s a lot of technology in Layer 1 - everything from physical network devices, cabling, to how the cables hook up to the devices. Plus if we don’t need cables, what the signal type and transmission methods are (for example, wireless broadband). Instead of listing every type of technology in Layer 1, I’ve created b...
Layer 2 is the data link layer. Layer 2 defines how data is formatted for transmission, how much data can flow between nodes, for how long, and what to do when errors are detected in this flow. In more official tech terms: 1. Line discipline.Who should talk for how long? How long should nodes be able to transit information for? 2. Flow control.How ...
Layer 3 is the network layer. This is where we send information between and acrossnetworks through the use of routers. Instead of just node-to-node communication, we can now do network-to-network communication. Routers are the workhorse of Layer 3 - we couldn’t have Layer 3 without them. They move data packets across multiple networks. Not only do ...
Layer 4 is the transport layer. This where we dive into the nitty gritty specifics of the connection between two nodes and how information is transmitted between them. It builds on the functions of Layer 2 - line discipline, flow control, and error control. This layer is also responsible for data packet segmentation, or how data packets are broken ...
Layer 5 is the session layer. This layer establishes, maintains, and terminates sessions. A session is a mutually agreed upon connection that is established between two network applications. Not two nodes! Nope, we’ve moved on from nodes. They were soLayer 4. Just kidding, we still have nodes, but Layer 5 doesn’t need to retain the concept of a nod...
Layer 6 is the presentation layer. This layer is responsible for data formatting, such as character encoding and conversions, and data encryption. The operating system that hosts the end-user application is typically involved in Layer 6 processes. This functionality is not always implemented in a network protocol. Layer 6 makes sure that end-user a...
Layer 7 is the application layer. True to its name, this is the layer that is ultimately responsible for supporting services used by end-user applications. Applications include software programs that are installed on the operating system, like Internet browsers (for example, Firefox) or word processing programs (for example, Microsoft Word). Applic...
The significant advantage of the CLEAR-like system is that it does not require Secret Internet Protocol Router Network (SIPR) access; therefore, it can be left with coalition partners without concern over security.
The DraGnET web application uses Struts to implement the Model-View-Controller (MVC) architecture. The view represents the presentation of the application and is implemented through Java...
