In electronic design, wire routing, commonly called simply routing, is a step in the design of printed circuit boards (PCBs) and integrated circuits (ICs). It builds on a preceding step, called placement, which determines the location of each active element of an IC or component on a PCB. After placement, the routing step adds wires needed to ...
Routing is the process of selecting a path for traffic in a network or between or across multiple networks. Broadly, routing is performed in many types of networks, including circuit-switched networks, such as the public switched telephone network (PSTN), and computer networks, such as the Internet. In packet switching networks, routing is the ...
Circuit switching is a method of implementing a telecommunications network in which two network nodes establish a dedicated communications channel (circuit) through the network before the nodes may communicate. The circuit guarantees the full bandwidth of the channel and remains connected for the duration of the communication session. [1]
Cisco Certifications are the list of the Certifications offered by Cisco Systems.There are four to five (path to network designers) levels of certification: Associate (CCNA/CCDA), Professional (CCNP/CCDP), Expert (CCIE/CCDE) and recently, Architect (CCAr: CCDE previous), as well as nine different paths for the specific technical field; Routing & Switching, Design, Industrial Network, Network ...
A broadcast forwarding pattern, typical of bridged Ethernet. The simplest forwarding model— unicasting —involves a packet being relayed from link to link along a chain leading from the packet's source to its destination. However, other forwarding strategies are commonly used. Broadcasting requires a packet to be duplicated and ...
PSTN network topology is the switching network topology of a telephone network connected to the public switched telephone network (PSTN).. In the United States and Canada, the Bell System network topology was the switching system hierarchy implemented and operated from c. 1930 to the 1980s for the purpose of integrating the diverse array of local telephone companies and telephone numbering ...
Virtual routing and forwarding. In IP-based computer networks, virtual routing and forwarding (VRF) is a technology that allows multiple instances of a routing table to co-exist within the same router at the same time. One or more logical or physical interfaces may have a VRF and these VRFs do not share routes.
Convergence is an important notion for a set of routers that engage in dynamic routing. All interior gateway protocols rely on convergence to function properly. "To have, or be, converged" is the normal state of an operational autonomous system. The Exterior Gateway Routing Protocol BGP typically never converges because the Internet is too big ...
