Packet Tracer is a cross-platform visual simulation tool designed by Cisco Systems that allows users to create network topologies and imitate modern computer networks. The software allows users to simulate the configuration of Cisco routers and switches using a simulated command line interface.
Carrier Routing System (CRS) is a modular and distributed core router developed by Cisco Systems Inc that enables service providers to deliver data, voice, and video services over a scalable IP Next-Generation Network (NGN) infrastructure. In a network topology, these routers are generally positioned in the core or edge of a service provider ...
RPL [1] (Routing Protocol for Low-Power and Lossy Networks) is a routing protocol for wireless networks with low power consumption and generally susceptible to packet loss. It is a proactive protocol based on distance vectors and operates on IEEE 802.15.4, [2] optimized for multi-hop and many-to-one communication, but also supports one-to-one ...
the use of explicit hello packets to discover and maintain adjacencies between routers. the use of a reliable protocol to transport routing updates. the use of a feasibility condition to select a loop-free path. the use of diffusing computations to involve the affected part of the network into computing a new shortest path.
Cisco IOS is versioned using three numbers and some letters, in the general form a.b(c.d)e, where: a is the major version number. b is the minor version number. c is the release number, which begins at one and increments as new releases in a same way a.b train are released.
An internetwork is the connection of multiple different types of computer networks to form a single computer network using higher-layer network protocols and connecting them together using routers. The Internet is the largest example of internetwork. It is a global system of interconnected governmental, academic, corporate, public, and private ...
[2] Side-by-side comparison between the OSI (left) and IEEE 802 (right) reference models The services and protocols specified in IEEE 802 map to the lower two layers (data link and physical) of the seven-layer Open Systems Interconnection (OSI) networking reference model.
Communications protocols use various conventions for distinguishing the elements of a packet and for formatting the user data. For example, in Point-to-Point Protocol, the packet is formatted in 8-bit bytes, and special characters are used to delimit elements. Other protocols, like Ethernet, establish the start of the header and data elements ...
