Abstract

We present an admission control framework and loss management techniques in support of a guaranteed statis-tical service.The service is characterized by(i)the loss rate of application data units(ADUs)bounded below a speci?ed value,and(ii)ADU losses distributed evenly among?ows subscribing to the service and uniformly over the duration of each?ow.Speci?cally,a?ow is modeled as a sequence of bursts,each of which is a sequence of packets that carry the bits of an ADU.The?rst packet of each burst carries infor-mation on the ADU(e.g.,its bandwidth requirement).This traf?c model enables admission control at the burst level as well as at the?ow level.Such a two level admission control approach is very effective in bounding end-to-end ADU loss rates of?ows while maintaining high channel utilization in the network.The traf?c model also enables simple tech-niques that can be used at a network channel to distribute ADU losses evenly among?ows subscribing to the same statistical service,and to protect high priority ADUs(e.g.,I frames of MPEG applications).

1Introduction

In all packet switching networks,packets have a maxi-mum size(in number of bits).Most application data units (ADUs)are too large to be carried in a single packet and must be segmented for network delivery.To an application, the end-to-end delays and loss rate of its data units are more relevant performance measures than ones speci?ed for in-dividual packets.For example,consider an application that sends a sequence of video pictures over an IP network.Each picture may be segmented into a sequence of IP packets. Clearly the loss rate of the pictures is much more important to the application than the loss rate of the packets.

However,packet delays and packet loss rate are the performance measures used in the Internet service model [21,23]and the ATM service architecture[9,11].Speci?-cally,three types of services have been identi?ed according to the quality of service(QoS)requirements for packets: deterministic(guaranteed),statistical(controlled-load),and best-effort.To provide better support to applications,we be-lieve that the service models should be extended to include QoS requirements for ADUs.

Best-effort service is well understood,and it is provided by the current Internet.There is also a fairly good under-standing of deterministic services following the recent de-velopment of rate-based packet scheduling algorithms(e.g., [17,19]).However,many important questions remain in characterizing statistical services.The lack of a good under-standing of statistical services is manifested in three areas: The loss rate of packets has been exclusively used as the performance measure.As discussed above,the loss rate of ADUs is much more relevant to an application.

In particular,because of segmentation,even a small rate of packet losses could result in a large number of ADU losses.

The term“statistical”is not well de?ned.There is a general consensus that it implies that a small fraction

of packets could be lost.1However,the consequence to

applications can be quite different depending on how

and at what time scale the loss rate is measured.For

example,if the loss rate is measured at a large time

scale,say over intervals of several hours,a large num-

ber of consecutive packets could be lost for a?ow even

when the measured loss rate is small.Such a statisti-

cal service(like the predictive service de?ned in[5])is

appropriate only for applications that can adapt to long

periods of persistent losses.Moreover,the important

issue of fair distribution of losses among?ows has not

received much attention.

Complex statistical traf?c models are often used in the

development of new techniques to provide statistical

performance guarantees at a small time scale(e.g.,over

intervals of milliseconds).Such models may not be

practical because(i)real world traf?c has long range

dependency[10],and(ii)traf?c monitoring and polic-

ing,if required,would be dif?cult to implement with a

complex statistical traf?c model.

This paper is concerned with providing a guaranteed sta-

tistical service to delay-sensitive?ows.The term statistical

means that the loss rate of the service may be nonzero.The

loss rate is measured in application data units lost(including

those late in arriving to their destinations).The term guar-

anteed means that the service’s loss rate can be accurately

predicted at connection setup time.In particular,we present

an admission control framework and loss management tech-

niques for providing the guaranteed statistical service.

We model a?ow as a sequence of bursts,each of which

is a sequence of packets that carry the bits of an ADU.The

?rst packet of each burst carries information on the ADU

(e.g.,its bandwidth requirement).This traf?c model en-

ables admission control by a network node at the burst level

as well as at the?ow level.To achieve high channel utiliza-

tion,overbooking is allowed in?ow level admission control.

Burst level admission control,on the other hand,is used to

ensure that the capacity of each channel is not exceeded by

2This part of our model can have different implementations.For exam-

ple in ATM networks,it may be desirable to use RM cells to mark bursts

and carry rate information.

Such a deterministic traf?c model makes burst-based rate allocation possible.Speci?cally,at each channel,a re-served rate is not allocated to an admitted?ow until the?rst packet of a burst arrives,and the rate is subsequently deallo-cated when the last packet of the burst departs[16].(At any time,at most one burst in each?ow is allocated its reserved rate.)As a result,the rate allocated to a VBR?ow is vari-able,i.e.,it changes from one burst to the next.Burst-based rate allocation has the advantage of allocating a rate that is exactly what a?ow needs at all time.

The burst concept and traf?c model are particularly ap-plicable to network design in support of application-level services[16,25].Speci?cally,they allow each ADU’s pack-ets to be processed as a whole,and independently from other ADUs.Consequently much more predictable performance for ADUs can be rendered.Moreover,networks can be de-signed to provide ADUs with delay guarantees so long as the capacity of each channel is not exceeded by the aggre-gate rate allocated[16].

In what follows,we assume that each?ow that subscribes to the guaranteed statistical service conforms to the deter-ministic traf?c model de?ned below.

De?nition1(deterministic traf?c model)A?ow is mod-eled as a sequence of bursts,each of which is a sequence of packets that carry the bits of an ADU.The?rst and last packets of each burst are marked.The?rst packet carries some information on the ADU(including its bandwidth re-quirement).

There are costs associated with requiring?ows to con-form to the above traf?c model,namely:the extra bits for encoding ADU information in some packets,and the extra processing by a network node to retrieve and act on the in-formation.However,they are bearable with today’s network technologies(especially hardware),and the potential bene-?ts outweigh the costs.In fact,my approach is consistent with the technology trend:It is advocated that the network be more active,i.e.to perform more application speci?c computations based on packet contents[8],so that better and more?exible services can be provided.3Admission Control by a Node

In this section,we describe an admission control algo-rithm that can be used by a node to bound the ADU loss rate at its channel below a speci?ed value.We will discuss how to perform nodal allocation of an end-to-end loss require-ment in Section5.

For designing admission control,we assume that the path of each?ow is?xed.For a particular?ow,its path is a sequence of nodes,each of which consists of an outgoing channel,and a set of buffers for the channel where packets of different?ows are queued.

Consider a particular node.Let(bits/second)be the channel capacity dedicated to a guaranteed statistical service with a target ADU loss rate of.(Note that it is straightfor-ward to extend our design to a channel that is hierarchically shared by different agencies,by multiple classes of statisti-cal services,etc.[1,25]).

In addition to bounding the ADU loss rate,another goal of admission control is to achieve high channel utilization. Next,we present a novel approach that combines admission control at the?ow level and admission control at the burst level to achieve both goals.

3.1Burst Level Admission Control

Our traf?c model,as discussed earlier,makes it possi-ble for the packets of a burst(ADU)to be processed as a whole,and independently from other bursts.Thus,separate admission control can be performed for each burst.Specif-ically,a burst is accepted only if the burst’s reserved rate3 does not exceed the channel’s unallocated capacity;other-wise,the entire burst will be discarded.(Note that a similar mechanism,called the ATM Block Transfer(ABT)capabil-ity,is being standardized by ITU-T[14].)

With burst level admission control,packet losses are con-centrated over a small number of ADUs,and channel capac-ity is not wasted on delivery of partial ADUs.4

Notation.In what follows,we use to index?ows,and use to index bursts.

The above algorithm has extremely low processing cost. Furthermore,it is performed only once per burst.Note that the average inter-burst arrival time is usually much larger than the average inter-packet arrival time.(This is espe-cially true in an ATM network.)Therefore,the algorithm is suitable for high speed networks.

3.2Flow Level Admission Control

Burst level admission control insures that channel ca-pacity is not exceeded at any time by discarding bursts if necessary.This ensures that delay guarantees can be pro-vided to bursts that are accepted by the node[16].Since all ADU losses are due to burst level admission control,the goal of?ow level admission control at the node becomes very speci?c:to allow as much overbooking as possible while bounding the probability that the channel’s unallo-cated capacity is not suf?cient for a newly arrived burst—denoted as the over?ow probability—by.The over?ow probability and statistical multiplexing gains are closely re-lated.In particular,if two channels have the same over?ow probablity,the utilization is higher,because of statistical multiplexing gains,for the one that has a larger capacity and is shared by more?ows.Therefore,our?ow level admission control exploits statistical multiplexing gains in an explicit manner.Flow level admission control condition

Assume that the statistical service of the node is currently shared by a set of?ows(indexed by).Each ?ow,say,supplies the following set of traf?c(TSpec) parameters when making a reservation with the node:sus-tained bit(or packet)rate,peak rate,and rate variance.At any time,with burst-based rate allocation, at most one burst in each?ow has its reserved rate allocated. Denote the reserved rate for the burst of?ow that is either allocated a rate or being processed by burst level ad-mission control at time.(if there is no such burst.)

In[24],we derived,using a generalized venison of cen-tral limit theorem,the following suf?cient condition to bound the burst loss rate at the node below:

The two level admission control algorithm is imple-mented for channel L1with a target ADU loss rate of .

Each video source makes a reservation with L1,and starts sending packets to the network only after the reservation is successful.Packets are scheduled based on their virtual clock values [27].The channel capacity of L1as well as the value of were varied in different experiments.We ran each

experiment for 10seconds of simulated time.

Channel utilization

In Figure 2,we plot the channel utilization as a function of the target picture loss rate .The result shows that the chan-nel is used much more ef?ciently with a statistical service than a deterministic service (with zero loss rate).The price to pay is a small non-zero picture loss probability.The uti-lization increase is more signi?cant with a higher channel capacity,from below 30%to above 70%in the case where the capacity of L1is 56Mbps.This is because the improve-ment is due to statistical multiplexing gains,which are larger with more ?ows sharing the channel.

that our admission control algorithm predicts the actual loss rate well when a large number of ?ows share the channel.(Around 30?ows were admitted when the channel capacity of L1was set to 56Mbps.)This agrees with our analysis;the larger the number of ?ows sharing the channel,the bet-ter approximation based on the central limit theorem.Note that the solid 45degree line represents perfect prediction by the central limit theorem.

4Loss Management at a Node

For the guaranteed statistical service to be viable,con-sidering the fact the service will be shared by many ?ows,the issue of loss distribution must be addressed.In partic-ular,the ADU losses should be distributed evenly among all ?ows subscribing to the service and uniformly over the duration of each ?ow.

In this section,we will discuss how to modify the admis-sion control algorithm to enable the channel to anticipate and manage ADU losses.6

We want to achieve two goals with such active loss man-agement .The ?rst goal is clear from the requirement of a guaranteed statistical service;that is,losses should be dis-tributed as evenly as possible among ?ows that share the channel.The second goal is motivated by the fact that to many applications,some of their ADUs are more important than others.For example,to an MPEG decoder,I frames are more important than either P or B frames.With our traf?c

Note that in SEAD-1,?ow level admission control is not modi?ed.The advantage is that high utilization can be maintained at the same time that high priority ADUs have a loss rate much smaller than.This advantage does come with a https://www.sodocs.net/doc/148144791.html,ly,those unmarked ADUs can experi-ence more losses.However,as stated in the theorem below, the overall ADU loss rate is still bounded,albeit by a value a little larger than.

5.2Usefulness of Non-Uniform Nodal Allocation

To answer the second question,we repeated the previous experiment with one simple modi?cation.Speci?cally,we assign different target loss rates to the four nodes:0.3%to the two upstream nodes (L1and L2)and 0.1%to the two downstream ones.As expected,the total losses,averaged over 20simulation runs,are very close for these two experi-ments (46losses in the new experiment vs.48in the original one).The percentage of total losses at each node for the new experiment is illustrated using a bar graph in Figure 6.The results indicate that given an end-to-end loss requirement,the ADU losses at downstream nodes can be reduced using non-uniform nodal allocation.Such reduction can be quite desirable for the purpose of minimizing wasteful work at the upstream nodes.(A similar observation has motivated pro-posals to give high priority to packets that have large hop counts.)Because ADUs usually have large sizes,the poten-tial gain of non-uniform nodal allocation,measured by ADU

losses,can be signi?cant.However as far as the overall net-work utilization is concerned,non-uniform nodal allocation does not cause any signi?cant change.

6Related Work

In this section,we review some related work in the area of application-level QoS.More discussion on related work can be found in [24].

Adaptive Resource Reservation

One main feature of the proposed deterministic traf?c model is that it enables resource reservation on a per ADU

basis for delay-sensitive VBR traf?c.The need for such

adaptive resource reservation was also independently dis-covered by several other researchers.Zhang and Knightly have proposed a renegotiated deterministic VBR service,called RED-VBR,based on their D-BIND traf?c model [26].Speci?cally,a compressed video source renegotiates its traf?c speci?cation and QoS with the network when its

?ow rate changes signi?cantly.When the renegotiation fails,the source adjusts the quality control factor of the video encoder to lower the transmission rate.Grossglauser et.al.have designed a Renegotiated-Constant Bit Rate (R-CBR)service for VBR ?ows using a similar approach [12].The main difference is that R-CBR builds the renegotia-tion service on top of a constant bit rate service.Chong et.al.have concentrated on the on-line prediction of the dy-namic bandwidth requirement of a VBR ?ow using neural networks [3].Additionally,several researchers (e.g.,in [2])have proposed to use in-call resource renegotiation as a fast reservation mechanism for bursty data traf?c.

Usefulness of Partially Delivered ADUs

Our work has been motivated by the distinction between packets and ADUs.In particular,it is assumed that the en-tire ADU would be considered lost by the application if one of the ADU’s packets is lost.It should be noted that there have been work such as the application level framing (ALF)proposal by Clark and Tennenhouse [6]that permits a partial ADU,i.e.one with some packet(s)lost,to be de-livered to the application.While partially delivered ADUs are useful to some applications,they cannot be utilized by

delay-sensitive applications without some QoS degradation. It is our view that the network should have the capabilities of(1)meeting the requirements of applications that cannot tolerate QoS degradation,and(2)limiting the degradation as much as possible for those that can.That is why in this work,partially delivered ADUs are considered the same as losses.Similarly,late ADUs are considered lost even though there are applications(e.g.,MBone audio/video tools)that can adapt to change of delays.

装修预留的尺寸标准

【精华】室内装修,必须预留的最佳尺寸标准大全 2014-08-29筑龙房地产筑龙房地产 阅读引语 强烈推荐大家存的一份装修预留尺寸标准!!非常实用!! 现在新房子的设计一般都会交给专门的设计师来做,但哪怕是专业设计师制作的设计图稿,没有实地接触的设计师可能还会存在一些设计尺寸上的死角。另 外,落实图稿的是施工队的工人,工人往往疏忽大意就会犯错。于是房子装修完了,总是小错误不断。因此小哥觉得大家有必要存一份尺寸标准,监工时要用起来 哦!且看且分享吧! PART1:【客 厅】 【面积:20平方米~40平方米】 客厅是居室的门面,可以说对家具尺寸的要求是最严格的,多大的沙发配多大的茶几,多远的距离适合摆放电视等等,别看都是一些小数字,却足以令你的客厅成为一个舒适协调的地方。

电视组合柜的最小尺寸? 【200×50×180厘米】 对于小户型的客厅,电视组合柜是非常实用的,这种类型的家具一般都是由大小不同的方格组成,上部比较适合摆放一些工艺品,柜体厚度至少要保持30厘米;而下部摆放电视的柜体厚度则至少要保持50厘米,同时在选购电视柜时也要考虑组合柜整体的高度和横宽与墙壁的面宽是否协调。 长沙发或是扶手沙发的椅背应该有多高? 【85至90厘米】 沙发是用来满足人们的放松与休息的需求,所以舒适度是最重要的,这样的高度可以将头完全放在*背上,让颈部得到充分放松。如果沙发的*背和扶手过低,建议增加一个*垫来获得舒适度,如果空间不是特别宽敞,沙发应该尽量靠墙摆放。 扶手沙发与电视机之间应该预留多大的距离?

【3米左右】 这里所指的是在一个29英寸的电视与扶手沙发或和长沙发之间最短的距离,此外,摆放电视机的柜面高度应该在40厘米到120厘米之间,这样才能让看者非常舒适。 与容纳三个人的沙发搭配,多大的茶几合适呢? 【120×70×45厘米或100×100×45厘米】 在沙发的体积很大或是两个长沙发摆在一起的情况下,矮茶几就是很好的选择,茶几的高度最好和沙发坐垫的位置持平。 目前市场上较为流行的是一种低矮的方几,材质多为实木或实木贴皮的,质感较好。 细节补充: 照明灯具距桌面的高度,白炽灯泡60瓦为100厘米,40瓦为65厘米,25瓦为50厘米,15瓦为30厘米;日光灯距桌面高度,40瓦为150厘米,30瓦为140厘米,20瓦为110厘米,8瓦为55厘米。 PART2:【餐 厅】 【面积:10平方米~20平方米】 用餐的地方是一家人团聚最多的地方,通常也是居室中较为拥挤的一个空间,因为有较多的餐椅需要放置,也是家人同时集中的地方,所以它的尺寸就更要精打细算才能使餐厅成为一个温馨的地方。
