leaky
The leaky bucket is an algorithm based on an analogy of how a bucket with a constant leak will overflow if either the average rate at which water is poured in exceeds the rate at which the bucket leaks or if more water than the capacity of the bucket is poured in all at once. It can be used to determine whether some sequence of discrete events conforms to defined limits on their average and peak rates or frequencies, e.g. to limit the actions associated to these events to these rates or delay them until they do conform to the rates. It may also be used to check conformance or limit to an average rate alone, i.e. remove any variation from the average.
It is used in packet-switched computer networks and telecommunications networks in both the traffic policing and traffic shaping of data transmissions, in the form of packets, to defined limits on bandwidth and burstiness (a measure of the unevenness or variations in the traffic flow). It can also be used as a scheduling algorithm to determine the timing of transmissions that will comply with the limits set for the bandwidth and burstiness applied by the network: see network scheduler. A version of the leaky bucket, the generic cell rate algorithm, is recommended for asynchronous transfer mode (ATM) networks in Usage/Network Parameter Control at user–network interfaces or inter-network interfaces or network-to-network interfaces to protect a network from excessive traffic levels on connections routed through it. The generic cell rate algorithm, or an equivalent, may also be used to shape transmissions by a network interface card onto an ATM network (i.e. on the user side of the user-network interface), e.g. to levels below the levels set for Usage/Network Parameter Control in the network to prevent it taking action to further limit that connection. The leaky bucket algorithm is also used in leaky bucket counters, e.g. to detect when the average or peak rate of random or stochastic events or stochastic processes, such as faults or failures, exceed defined limits.
At least some implementations of the leaky bucket are a mirror image of the Token Bucket algorithm and will, given equivalent parameters, determine exactly the same sequence of events to conform or not conform to the same limits. However, there are at least two different descriptions of the leaky bucket that can and have caused confusion.
i have leaking primatic cylinder which is leaking on the return heating tapping on the cylinder,whats the best way to repair the leak,any comments would be welcome,ajoint
This is my neighbours 5 1/2yr old Grant. By the sound of its ignition it had never been commissioned or serviced and now the jacket has burst!! That's karma!
I don't get on with the bloke so not involved with the replacement but am trying to blag the scrap to rob it of spares :-)
Hi,
My kitchen tap has recently started to leak (at the joint where it rotates). I have managed to remove the relevant part and taken it to a couple of local Basingstoke plumbing supplies in an attempt to obtain replacement washers. But I am told that the washers are special and it is...
Plumbing in a bath and basin today and had 4 leaks on pipework. All on solder fittings. Looked at my tub of flux and I'd dropped a load of crud in it. Really peed me off as the tub was nearly new. Then cleaning the muck out of the flux I flicked some in my eye so, even after using the eyewash, I...
Afternoon chaps.
Righto, had quite a few leaks from my bath as of late, fixed most of them and then traced another puddle to the waste.
I've had a good go, but know these can be troublesome from some searching.
What I've done is stripped it all apart, cleaned it, re seated the chrome drain...
whats the quickest eand easiest way to sort out a leaky rad tapping witout changing the system down?also i have a control valve on one side of the rad ,i turned with the pump pliers and its leaking water?i turned it because radiator is not getting hot as system been recently piped up.thanks,ajoint.
danparty92,my cousin has a leaky rad tapping,whats the easiest and simplist way to either repair it or replace it,system is combi boiler,a plumber in college says first you have to release the pressure in system on the pressure switch in boiler,is that correct,i am thinking that you are quite a...
i have a soil stack pipe which comes down through my consevatory roof which we have never been able to waterproof properly so i would like to know if there is an internal system which means i can do away with the pipe through the roof and have a dry floor when it rains!

We have oil-fired CH with 3 motorized valves (for HW, CH and UFCH, downstairs). Recently, I have noticed that the boiler comes on at times when it should not, according to timers and thermostats. WHen this happens, the valves (ACL Lifestyle) are all in the closed position. THe only way to turn...

Hi all...we have a problem! We have two bathroom taps that leak from underneath the cap when they are on. They are single level mixer taps. We are not sure what to do!!! Some pictures attached.
Can anyone suggest what might be wrong and what part we will need. Or can they identify the tap...
Hi guys, does anybody know what the black plastic part is called where the pressure guage and tail from the expansion vessel fits into? (leaking from the back where it meets the pump block) and how to change it,
cheers,

We've had a lot of rain here the past few days and one of my windows is leaking, I've had a look to see if I can locate where it is coming in but, no joy. Is there a plumber in the Lincolnshire area that could help me out? Maybe the cold feed needs changing? Just a guess, any help would be...
Hi everyone. First post so here goes. I have a Bosch Worcester 35CDI II combi boiler. It keeps losing pressure, not by much but gradually goes down slowly from say 1 bar which is what I have it set at to around .7 bar at the moment. I keep topping it up to 1 bar but it loses pressure after a...
Can any one tell me how to repair a 6month old Prestige sagittarius kitchen mixer tap.Cold water is leaking badly,water is leaking from inside the body of the tap and running down the holding down bolts,I have isolated the cold water supply and we can use the tap hot water only.The supply pipe...
Hi all,
I've fitted a new bathroom suite this week.
All done, except for this:
I cannot get the trap under the basin to seal properly. When I hand- tighten the trap's upmost nut to the threaded metal waste outlet, there's still 'give' in the trap inlet, i.e. you can move / waggle it.
As a...
Afternoon,
One leaking shower. A Bristan 1901. Installed 6 years ago in a customer's house. It's leaking, as the second picture shows, from between the handle section and the very next gold ring section. It's a constant drip.
My questions are:
1) Which part(s) would I need to replace? I'm...
I've been trying find good information about leaky toilets - what do I mean and why? Well there has been a lot of discussion in water regs circles that the changes in 1999 which brought about the introduction of valve flushing mechanisms has created an enormous increase in faulty toilets and the...
Hello all - I posted a few weeks age regarding a constant pressure drop on my Worcester Junior boiler - various things had gone wrong and within a few months : the expansion vessel was recharged the condense pipe was replaces with wider pipe - I was (before coming onto thread) advised by my...
