Abstract: A telecommunication and network traffic throttle and control and rate deck synchronization system including one or more processors coupled to a communications network. The system is configured to monitor, control, and throttle network traffic and to generate and synchronize rate decks to limit and block unwanted and harmful traffic to optimize performance of and protect telecommunications and network infrastructure. Received routing requests are parsed for subscriber identifiers that have assigned current rate decks. Routing requests are forwarded only for subscribers having unexpired assigned rate decks. When new assigned rate decks are generated with prospective effective times, the current date decks are modified to expire before the effective time, and subscribers are sent URLs having embedded security hashes, which must be downloaded before the current assigned rate decks expire.
