What is throttling package?
A throttling packet is used in network maintenance and quality management to inform a specific node or sender that its transmitted traffic is creating an overload on the network. This forces the node or sender to reduce its rate of output.
Choke packets are used for congestion and flow control over a network. The source node is addressed directly by the router and forces it to reduce its transmission rate. The source node confirms this by reducing the sending rate by a few percent.
An Internet Control Message Protocol (ICMP) source deletion packet is a type of choke packet typically used by routers.
The technique of a choke packet to detect and restore congestion control uses routers. The routers often check for anomalies over the network by examining factors such as line load, queuing and the length of buffers. In the event of an overload, routers send choke packets to all relevant segments in order to reduce their data throughput. The source node overloading the network must reduce throughput by a certain factor, depending on circumstances such as the size of the bottlenecks, the available bandwidth, and the buffer size.
