Troubleshooting is a form of problem solving, often applied to repair failed products or processes on a machine or a system. It is a logical, systematic search for the source of a problem in order to solve it, and make the product or process operational again. Troubleshooting is needed to identify the symptoms.
An alarm is a persistent indication of a fault that clears only when the triggering condition has been resolved. A current list of problems occurring on the network component is often kept in the form of an active alarm list such as is defined in RFC 3877, the Alarm MIB. A list of cleared faults is also maintained by most network management ...
Computer networks enhance how users communicate with each other by using various electronic methods like email, instant messaging, online chat, voice and video calls, and video conferencing. Networks also enable the sharing of computing resources. For example, a user can print a document on a shared printer or use shared storage devices.
If you're using broadband (cable) internet and you can't connect, try the following troubleshooting steps in the order listed until you get up and running again. 1. Check if you can visit other sites with a different browser - If you can go to another site, the problem may be associated the browser you're using.
In networks with distance-vector routing protocols, route flapping can trigger routing updates with every state change. In both cases, it prevents the network from converging. Route flapping can be contained to a smaller area of the network if route aggregation is used. As an aggregate route will not be withdrawn as long as at least one of the ...
In [11] the authors report on the generalized Dijkstra algorithm, which can be used to efficiently and optimally solve the RWA, RSA, and the routing, modulation, and spectrum assignment (RMSA) problems, without the limit on the path length.
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.
It is used for finding problems in the network and to determine the amount of traffic on the network as a performance measurement. [1] On Linux this program is mostly obsolete, although still included in many distributions. On Linux, netstat (part of "net-tools") is superseded by ss (part of iproute2).
