Switching loops can cause misleading entries in a switch's media access control (MAC) database and can cause endless unicast frames to be broadcast throughout the network. A loop can make a switch receive the same broadcast frames on two different ports, and alternatingly associate the sending MAC address with the one or the other port.
Most commonly the cause is a switching loop in the Ethernet network topology (i.e. two or more paths exist between switches). A simple example is both ends of a single Ethernet patch cable connected to a switch.
In the C programming language, Duff's device is a way of manually implementing loop unrolling by interleaving two syntactic constructs of C: the do-while loop and a switch statement. Its discovery is credited to Tom Duff in November 1983, when Duff was working for Lucasfilm and used it to speed up a real-time animation program.
In a simple reachability protocol, such as EGP, the routing loop will persist forever. In a naive distance-vector protocol, such as the routing information protocol, the loop will persist until the metrics for C reach infinity (the maximum number of routers that a packet can traverse in RIP is 15. The value 16 is considered infinity and the ...
The control action is the switching on/off of the boiler, but the controlled variable should be the building temperature, but is not because this is open-loop control of the boiler, which does not give closed-loop control of the temperature. In closed loop control, the control action from the controller is dependent on the process output.

With the split-horizon rule in place, this particular loop scenario cannot happen, improving convergence time in complex, highly-redundant environments. Split-horizon routing with poison reverse [ 4 ] is a variant of split-horizon route advertising in which a router actively advertises routes as unreachable over the interface over which they ...
Kelly of Loop agrees that AI can be used at the time a customer is initiating a return and flag returns that may be fraudulent, such as if a customer may be returning an empty box or swapping the ...
