Graphical Network Simulator-3 (shortened to GNS3) is a network software emulator first released in 2008. [2] [3] [4] It allows the combination of virtual and real devices, used to simulate complex networks. It uses Dynamips emulation software to simulate Cisco IOS. [2]: 55 [5]
Marionnet is a virtual network laboratory: it allows users to define, configure and run complex computer networks without any need for physical setup. Only a single, possibly even non-networked Linux host machine is required to simulate a whole Ethernet network complete with computers, routers, hubs, switches, cables, and more Support is also provided for integrating the virtual network with ...
Open vSwitch deployed as a cross-server virtual network switch, transparently distributed across multiple physical servers.[3]Open vSwitch is a software implementation of a virtual multilayer network switch, designed to enable effective network automation through programmatic extensions, while supporting standard management interfaces and protocols such as NetFlow, sFlow, SPAN, RSPAN, CLI ...
In computer network research, network simulation is a technique whereby a software program replicates the behavior of a real network. This is achieved by calculating the interactions between the different network entities such as routers, switches, nodes, access points, links, etc. [1] Most simulators use discrete event simulation in which the modeling of systems in which state variables ...
These visual maps are automatically generated by scanning the network using network discovery protocols. Some of these tools integrate into documentation and monitoring tools. Typical capabilities include but not limited to: Automatically scanning the network using SNMP, SSH, WMI, etc. Scanning Windows and Unix servers; Scanning virtual hosts
The Crossbow project software, combined with next generation network interfaces like xge and bge, enable network virtualization and resource control for a single system. By combining VNICs with features such as exclusive IP zones or the Sun xVM hypervisor, system administrators can run applications on separate virtual machines to improve performance and provide security.
It also supports file transfers, chat functionality and various authentication methods. The two computers must be able to communicate across a network, such as a local subnet, internal network, or the Internet. The software is free and distributed under the terms of the GNU General Public License.
TightVNC is a free and open-source remote desktop software server and client application for Linux and Windows.A server for macOS is available under a commercial source code license only, without SDK or binary version provided. [3]
