NotifierQueue -- Click element; stores packets in a FIFO queue
Ports: 1 input, 1-2 outputs
Package: standard (core)
Stores incoming packets in a first-in-first-out queue. Drops incoming packets if the queue already holds CAPACITY packets. The default for CAPACITY is 1000. NotifierQueue notifies interested parties when it becomes empty and when a formerly-empty queue receives a packet. The empty notification takes place some time after the queue goes empty, to prevent thrashing for queues that hover around 1 or 2 packets long. In all other respects, NotifierQueue behaves like SimpleQueue. Multithreaded Click note: NotifierQueue is designed to be used in an environment with at most one concurrent pusher and at most one concurrent puller. Thus, at most one thread pushes to the NotifierQueue at a time and at most one thread pulls from the NotifierQueue at a time. Different threads can push to and pull from the NotifierQueue concurrently, however. See ThreadSafeQueue for a queue that can support multiple concurrent pushers and pullers.
The Queue element acts like NotifierQueue, but additionally notifies interested parties when it changes state from nonfull to full or vice versa.
