In telecommunication and computer engineering, the queuing delay ( or queueing delay ) is the time a job waits in a queue until it can be executed.

The maximum queuing delay is proportional to buffer size.

In Kendall's notation, the M / M / 1 / K queuing model, where K is the size of the buffer, may be used to analyze the queuing delay in a specific system.

A traffic intensity greater than one erlang means that the rate at which bits arrive exceeds the rate bits can be transmitted and queuing delay will grow without bound ( if the traffic intensity stays the same ).

Message switching is thus an example of a delay system or a queuing system.

However, it should be noted that the increased link speeds by themselves do not alleviate jitter due to queuing.

Tickets can be bought at the TACV shop at each airport by queuing and paying in cash ( euros or escudos ).

The formula was derived by Agner Krarup Erlang and is not limited to telephone networks, since it describes a probability in a queuing system ( albeit a special case with a number of servers but no buffer spaces for incoming calls to wait for a free server ).

# And where do I recover my business from ... Will the business center give me space to work, or would it be flooded by many people queuing up for the same reasons that I am.

In practice, this minimal latency is further augmented by queuing and processing delays.

If a bottle neck communication link offering data rate R is shared by " N " active users ( with at least one data packet in queue ), every user typically achieves a throughput of approximately R / N, if fair queuing best-effort communication is assumed.

Batch processing methodologies evolved to decrease these " dead periods " by queuing up programs so that as soon as one program completed, the next would start.

Therefore, most modern mutual exclusion methods attempt to reduce latency and busy-waits by using queuing and context switches.

It can also refer to a program that allocates computer component space and schedules computer events by task queuing and system interrupts.

Most Internet backbone links are now so fast ( e. g. 10 Gbit / s ) that their delays are dominated by the transmission medium ( e. g., optical fiber ) and the routers driving them do not have enough buffering for queuing delays to be significant.

Recent research ( Buston, 2004 ) suggests that they are simply queuing for the territory occupied by the breeders, i. e. the anemone ; non-breeders living in association with breeders have a better chance of eventually securing a territory than a non-resident.

The queuing path leads guests past a pet cemetery, a mausoleum with pun names, and a white carriage hearse led by an invisible horse.

Network Address Translation ( NAT ) and Quality of Service ( QoS ) have been integrated into PF, QoS by importing the ALTQ queuing software and linking it with PF's configuration.

The company has also posted notices to encourage orderly queuing at bus stops after a series of incidents where pedestrians on the foot path were struck on the head by the wing mirrors of city buses.

The evolution of cooperative breeding by delayed reciprocity and queuing for favorable social positions.

Disney Fastpass is a virtual queuing system created by the Walt Disney Company.

Due to football matches at the American Express Community Stadium being served by train services from Brighton to Falmer, a queuing system is in operation from 2 hours before kick off for trains departing from platforms 7 and 8.

The queue for Nickelodeon Studios is now used by Total Nonstop Action Wrestling for queuing up audiences for its production of TNA Impact!

Rate limiting is performed by policing ( discarding excess packets ), queuing ( delaying packets in transit ) or congestion control ( manipulating the protocol ’ s congestion mechanism ).

The meager green space of Plaza Miserere is usually taken up by illegal peddlers, people queuing for their bus, and preachers of all stripes.

* Immediately decongest passenger-handling capacity in the existing departure area by rationalizing office and commercial space to increase the number of check-in counters and queuing space.

Such techniques are the classic rear-end shunt ( the driver in front suddenly slams on the brakes, possibly with brake lights disabled ), the decoy rear-end shunt ( when following one car, another one pulls in front of it, causing it to brake sharply, then the first car drives off ) or the helpful wave shunt ( the driver is waved in to a line of queuing traffic by the scammer who promptly crashes, then denies waving )

" Some proposed pieces of legislation would even make fair queuing illegal as it requires prioritization of packets based on criteria other than that permitted by the proposed law.

Access to resources is also sometimes regulated by queuing ; in the case of computing time on a CPU the controlling algorithm of the task queue is called a scheduler.

Although jitter is a random variable, it is the sum of several other random variables that are at least somewhat independent: the individual queuing delays of the routers along the Internet path in question.

The queuing area winds through several courtyards outside before entering the actual fortress show building.

He also published several important works on statistical physics, where he used the methods of probability theory, and on information theory, queuing theory and mathematical analysis.

There are several service disciplines which track the performance of GPS quite closely such as weighted fair queuing ( WFQ ) also known as packet-by-packet generalized processor sharing ( PGPS ).

MPLS recognizes that small ATM cells are not needed in the core of modern networks, since modern optical networks () are so fast ( at 40 Gbit / s and beyond ) that even full-length 1500 byte packets do not incur significant real-time queuing delays ( the need to reduce such delays — e. g., to support voice traffic — was the motivation for the cell nature of ATM ).

In telecommunication, a distributed-queue dual-bus network ( DQDB ) is a distributed multi-access network that ( a ) supports integrated communications using a dual bus and distributed queuing, ( b ) provides access to local or metropolitan area networks, and ( c ) supports connectionless data transfer, connection-oriented data transfer, and isochronous communications, such as voice communications.

Alternatively, the packets may be forwarded according to some scheduling discipline for fair queuing, traffic shaping or for differentiated or guaranteed quality of service, such as weighted fair queuing or leaky bucket.

Modern BSD implementations, such as FreeBSD, NetBSD and OpenBSD, have support for ECN marking in the ALTQ queueing implementation for a number of queuing disciplines, notably RED and Blue.

Improvements in modern hard drives such as RAM cache, faster platter rotation speed, command queuing ( SCSI TCQ / SATA NCQ ), and greater data density reduce the negative impact of fragmentation on system performance to some degree, though increases in commonly used data quantities offset those benefits.

They are used primarily to determine the precise position of the train when it is being brought to a halt at a station, so that the doorway positions will align correctly with queuing points on the platform or with a second set of safety doors should such be provided.

various secondary effects, such as queuing effects in multiprocessor systems

AHCI is separate from the SATA 3 Gbit / s standard, although it exposes SATA's advanced capabilities ( such as hot swapping and native command queuing ) such that host systems can utilize them.

WDI is responsible for technological advances such as the Circle-Vision 360 ° film technique and the FastPass virtual queuing system.

Teletraffic engineers use their basic knowledge of statistics including queuing theory, the nature of traffic, their practical models, their measurements and simulations to make predictions and to plan telecommunication networks such as a telephone network or the Internet.

Rationing and queuing became a way of life, with ration cards ( Kartki ) necessary to buy even such basic consumer staples as milk and sugar.

Surgery where immediate treatment is required is not in the remit of Choose and Book since such patients ' needs bypass any longer-term queuing systems.

* Non-monetary bargaining methods, such as time ( for example queuing ), nepotism, or even violence.
