SERIAL REDUNDANT BYPASS CONTROL MECHANISM FOR MAINTAINING NETWORK BANDWIDTH MANAGEMENT SERVICE

摘要

A serial redundant bypass control mechanism for maintaining network bandwidth management service (300) includes a first (305) and second (307) bypass control module, a first (306) and second (308) bandwidth management control module, and a first bypass (309) connector line connecting the first bypass control module (305) to the second bypass control module (307). If the first bandwidth management control module (306) fails, the network signal is received at the first bypass control module (305) and transported directly to the second bypass control module (307) along the first bypass connector line (309), thus bypassing the failed first bandwidth management control module (306). The network signal is then transported to the second bandwidth management control module (308) where bandwidth management services are performed on the network signal. The second bandwidth management control module (308) then transports the network signal back to the second bypass control module (307) and outputs the network signal.
