摘要
A serial redundant bypass control mechanism for maintaining network bandwidth management service includes a first and second bypass control module, a first and second bandwidth management control module, and a first bypass connector line connecting the first bypass control module to the second bypass control module. Under normal conditions, a network signal is received at the first bypass control module and transported to the first bandwidth management control module. The first bandwidth management control module performs bandwidth management services on the network signal and transports the network signal back to the first bypass control module. The first bypass control module then transports the network signal to the second bypass control module along the first bypass connector line. Next, the second bypass control module transports the network signal to the second bandwidth management control module. Since bandwidth management services have already been performed on the network signal, the second bandwidth management control module transports the network signal back to the second bypass control module and outputs the network signal.;If the first bandwidth management control module fails, the network signal is received at the first bypass control module and transported directly to the second bypass control module along the first bypass connector line, thus bypassing the failed first bandwidth management control module. The network signal is then transported to the second bandwidth management control module where bandwidth management services are performed on the network signal. The second bandwidth management control module then transports the network signal back to the second bypass control module and outputs the network signal.
