The type that provides a function object that can compare two element values as sort keys to determine their relative order in thepriority_queue. This argument is optional and the binary predicateless<typename Container::value_type>is the default value. ...

If two elements carry the same priority, they are served as per their order in the queue. Now, the one above is a definition from Google, but to try to understand it better, let's compare it with a normal queue. A Queue follows the principle of FIFO(First In, First Out), which ...
In the PFC profile, only monotonically increasing priority levels with traffic-class are supported. For example, TC7 should be p1, TC6 should be p2, and so on, until TC1 is p7 with class-default being lowest priority. Rate classes can be mixed...
As the packets arrive at an interface, the priority queues on that interface are scanned for packets in a descending order of priority. The high priority queue is scanned first, then the medium priority queue, and so on. The packet at the head of the highest priority queue i...
A natural alternative is to let customers pay and upgrade to priority at any time during their stay in the queue, even if they choose not to do so initially. This paper builds a queueing-game-theoretic model that explicitly captures self-interested customers’ dynamic in-queue priority-...
priority enqueued item at a head of the functional queue; modifying at run time the sort criteria in memory while the functional queue contains the enqued items in memory; and re-prioritizing the enqued items in the functional queue at run time according to the modified sort criteria in ...
technique is known as first in, first out (FIFO) or first-come, first-served (FCFS) queuing. This can be regarded as the simplest scheduling method. Packets are placed into a single queue and serviced in the order of their arrival. There are obvious limitations to such a queuing technique...
queue, it registers its own priority in the request word by marking the assigned channel thereof provided that this channel is free. If not, the unit waits for the next access request word. Each unit includes a counter which is incremented by one for each priority, marked in the passing ...
