The STP algorithm does not determine that a topology changes until the timer expires, delaying network convergence. The STP algorithm requires the root bridge to send configuration BPDUs after the network topology becomes stable, with other devices processing and spreading the configuration BPDUs throug...

As you have seen, the transparent bridging algorithm floods unknown and broadcast frames out of all the ports that are in the same VLAN as the received frame. This causes a potential problem. If the network devices that run this algorithm are connected together in a physical loop, flooded fra...
2)Enter the interface configuration mode of the suspicious ports, and then run the loopback-detection command to enable loopback detection on these ports. If a loop is detected on these ports, the switch will send a trap and generate an entry on the log file. 21 In Which Scenario Can ...
Algorithm—Switch Based Algorithm (SBA) The aforementioned loop formation is implemented in software and if looping conditions are found to greater than expected number of iteration then loop process will continue until end state is reached. All the loop formation is simplified and it is mentioned ...
The proposed scheduling algorithm then focuses only on the switch configuration to forward the data packets. Benefitting from the parallel processing capabilities of FPGA-based switch controller, the proposed scheduling scheme can be easily scaled out to support more than 64 ToRs in one cluster. ...
routers keep in regular contact with each other via “hello” messages indicating that nothing has changed. For these reasons, link state protocols tend to converge more quickly. The protocols are based on Dijkstra’s algorithm for finding the best path between points on a graph. OSPF is an ...
Upon detection of a clock-signal failure, the clock detector switches to a backup input clock signal and, depending on the magnitude of the phase offset between the failed input clock signal and the backup input clock signal, temporarily changes the divisor value used by the PLL and applies a...
4. For example, referring to modem 447 (FIG. 6), on the trailing edge of the next bit clock following detection of the frame sync signal (FIG. 4), the assigned time slot number of modem 447 is loaded from a latch in the dsp serial interface logic 437 (FIG. 6) to a set of ...
