IPacketBuffer¶

module interface IPacketBuffer

Interface for packet buffer modules. A packet buffer is often used by packet queues to store packets in a limited shared resource. Packets can be added to and removed from a packet buffer. When the buffer becomes overloaded, one or more packets are dropped according to the configured dropping strategy. For each dropped packet, the packet owner is notified in order to update its internal state.

Implemented by¶

Name	Type	Description
PacketBuffer	simple module	Provides packet storage for sharing and optimizing storage space between multiple packet queues. When a packet buffer becomes overloaded, the packet dropping strategy can drop any number of packets from any number of connected packet queues.
PriorityBuffer	simple module	This buffer drops packets among the connected packet queues based on their module ID.

Used in compound modules¶

Name	Type	Description
Ieee8021qTimeAwareShaper	compound module	Implements the IEEE 802.1Q time aware shaper.
GatingPriorityQueue	compound module	Implements a priority queue with multiple inner queues each having its own periodic gate for packet selection and an optional shared memory buffer.
PriorityQueue	compound module	Implements a priority queue with multiple inner queues and an optional shared memory buffer.

Properties¶

Name	Value	Description
display	i=block/buffer
