Meaning
Administrative bandwidth limitation restricts the throughput of data across a telecommunications network to preserve system stability. Strategic network traffic throttling reduces the speed of specific protocols or origins during periods of high congestion. The measure prevents a total outage by ensuring that critical services retain a minimum level of connectivity.
The boundary of this practice is defined by the service level agreement between the provider and the subscriber.
Congestion Management
Routers monitor the queue length and drop packets or delay transmission when the load exceeds the available capacity. Applying network traffic throttling allows the operator to prioritize low-latency applications over bulk file transfers. Performance drops significantly when the packet loss rate crosses the two percent threshold.
Regulatory Oversight
Ministry of Industry and Information Technology (MIIT) regulations govern how internet service providers manage traffic during public emergencies. While network traffic throttling is a standard technical tool, its use for anti-competitive purposes is prohibited under the PRC Anti-Monopoly Law. Transparency requirements force providers to disclose the conditions under which speed reductions occur.
Operational Consequence
International corporations often experience latency issues when VPN traffic is deprioritized by local nodes. Persistent network traffic throttling impacts the synchronization of real-time databases across global offices. Engineers mitigate this by using dedicated leased lines that are exempt from the standard public throttling queues.
These circuits provide a guaranteed throughput regardless of the general network load.
