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.
1. Cisco Packet Tracer. Cisco’s Packet Tracer is perhaps the most famous of all network simulation tools, especially for practicing on Cisco CCNA certification. It is functional, easy to use, and is accessible for educational institutions or for people who enrolled in Cisco’s Net Academy (free of charge). The highlight of the Packet Tracer ...
Drag Net Quick Start. Rane’s tradition of writing a one page Quick Start section in our manuals has been revamped. Since this section is four pages, it’s called the Mostly Quick Start section. Drag Net software installation is straight forward — just run the setup.exefile included on the CD-ROM or downloaded from Rane's website (www.rane ...

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...
Aug 9, 2013 · But the government's dragnet is not confined to the fiber-optic cables running across domestic boundaries. Recent reporting by Brazil's O Globo , Germany's Der Spiegel , and Australia's Sydney Morning Herald — all based on documents obtained from Edward Snowden — paint a picture of an interconnected network of communications cables and facilities across the world to which the United States ...
Drag Net. Drag Net is a Windows-based software application used to configure, control and monitor the RPM 88, RPM 44, RPM 22, RPM 2, RPM 2m and RPM 26z Programmable Multiprocessor family of fully-configurable DSP-based products and their remote controls. Drag Net features an intuitive drag-and-drop style user interface, with standard 10Base-T ...
