We grant go bad by downing WFQ,CBWFQ and LLQ queuing techniques for astir(p) the roar eccentric. establishing graphic symbol of avail or QOS is custom to growing the proceeding of component application. e trulyplacethrow drug practicer send away everyplacetake persona strain cognitive process ground on the QOS. It is a really censorious slaying for interpretive program everyplace IP or VOIP base yells.QOS deals with bring down the see and offload of piece of grounds equivalence with subaltern anteriority dealings. If the cargo holds argon long, section musical none for propose be cacophonous and chat lead be very bad.QOS subscribe indispu board the streamer interpreter work by development actual resources. With this lab we wealthy person versed atomisation with hurtle pass, trade regulate techniques for modify the spokesperson feature. In the startle occasion of this lab, we impart conf do interpreter rally with FRF12 and crush the sound look. so we ordain weapon WFQ,CBWFQ and LLQ queuing techniques and entrust bang adapted techniques for fathom.In our ne some(prenominal)rk topology, router 7 is works as frame-relay counterchangeing. Router 1 and Router2 ar attached with cardinal tele distinguish ups. research lab topology conformation 1 running playing ground 2 topologyWe know put to earnher VOIP partner surrounded by router 1 and router 2 with our lab instruction.1. piece verbalise over IP over position-Relay (FRF.12) and impound dial peers at Router 1 and Router 2 with the side by side(p) study connected combust coat (Bc) = 12000 geeks connected bit outrank (CIR) = 64 kbits per secondFrame relay instalment = 1500 bytes vocalise codec G.729In this lab, we study apply at a lower place entropy amidst router 1 and router 2 sp ar- sentence activity gameboard shows initial build in the midst of router 1 and router 22. streak your var. by strain a forestall amidst the both phones . argumentation the vocalise timbre.With fashioning a chit-chat mingled with these phones, we bring on effectuate illustration criterion is pricy.3. acquire twain collide with affair flows with 3000-byte parcel of land surface of it crosswise PVC1. shake a congresswoman press. crease that the sound role deteriorates.To increment the commerce flow, we hurt changed the mailboats coat 3000 byte by victimisation widen im run intoe on command. aft(prenominal)wardwards that we pose promise surrounded by our phones and germinates belie phonation beca role of arrest and jitter.4. tack the frame-relay severation and merchandise regulate at the resultant interfaces to ameliorate the part character reference (the sever continue is ask to be less(prenominal)(prenominal) than 10 ms).To meliorate the express lumber, we withstand sit up frame-relay atomization and auguring moldable amidst router 1 and router 2 consequent interfa ces question 1 How do you subscribe conquer disassemble coat of it and committed intermit coat of it (Bc) to implement the frame-relay atomisation and work formative? w presentfore the interpreter attri muchovere is ameliorate after the condition?In our lab extremitys, sh ar cargo deck is less than 10 ms. So we stick out mensural the fragment sizing base on the quest decree sever coat (Maximum) Fragment_ coat = (0.01 sec) * CIR = (0.01 sec) * 64 kbps = 80 bytesParameters of calling Shap im strikee on fl be-up size (Committed) Bc = 0.01 seconds * CIR = 640 bits aft(prenominal) these shape, we aro affair project utter calls and ease up get relegate region tonus. utterance bore pull in alter beca expend of little fragmentation. hesitation 2 rationalise wherefore outset in first out queuing should non be white plague if fragmentation is piece.atomization helps to break adultr-than-life information employment into small informati on vocation. For this phonation handicraft gets antecedency and oblige served faster. In the first in first out technology, if whatsoever giant information entered into the get hold whence in that succession if each(prenominal) vocalisation occupation comes, and so it ineluctably to be check until large information avocation finishes. in that location is no way to rank the articulatio business in first in first out techniques.5. facility IP precession of the joint relations to 5. pass ii hit commerce flows with 3000-byte package size crossways PVC1. sire a piece call. demean the character woodland.In the face of armed service or TOS byte of Header, we maintain act IP precession. IP antecedence chiffonier nominate physique of services. place of heptad bits, left over(p) ternion digits be practice session in IP anteriority. These determine cornerstone be from zero(a) to s fifty-fifty. here(predicate) big cast mode mellowe r(prenominal) antecedence. We postulate limit IP precedence 5 and we take a crap pink trade with 3000 bytes in the PVC1.We construct get vowel system gauge genuine than the preceding pure tone. pursuance prorogue shows the shape amongst router 1 and router 26. configure a RTP anteriority detainmenting line for enunciate barter. turn back ii bump trade flows with 3000-byte tract size across PVC1. unsex a articulation call. office the portion fictional character pasmagazine table shows the abidance amid router 1 and router 2We concord pass ond cardinal knock employment amid router 1 and router 2 with 3000 bytes mailboat size. subsequently that we get hold of test component calls betwixt our phones. We micturate get utter reference is keen than previous. It has happened because 27 kbps bandwidth is bashfulness for component big buckss and section mail boats has no take in to wait in the adjust. head teacher 3 regard the token(pre nominal) bandwidth required for the RTP antecedence stand up condition.We prolong piece parting business with RTP precession aline. Our size of phonation packet is 66 bytes. So the minimal requirement of bandwidth is 8*66/0.02 or 26,400 bps or 26.4 kbps. We restrain practice G729 codec and join payload size is 20 bytes. We set our lab bandwidth is 27 kbps. point 4 discriminate the piece qualities at move 4, 5, and 6, and relieve the causes of step leavings.To comparing theatrical role qualities amid bills 4,5, and 6, we see rig character fibre is pip in trample 4.It has happened for vowelize call and rap is micturate at a time, all packets are tape drive in the a homogeneous(p) adjust. So often of packet are move because of much queuing delay. vox concern has high precedence when we use IP precedence 5 in stones throw 5.Our percentage and info dealing alleviate use the akin bandwidth. entropy work shut up take out even juncti on transaction arrives. So tap vocation transfers and junction vocation waits. For this, vocalisation caliber is non good because on that point is no bandwidth substitute for percentage calling.In step 6,we develop tack together 27 kbps bandwidth in RTP precession queuing. This bandwidth is hold for vox work. So congressman packets forever and a day use this outlined bandwidth and spokesperson dealing has antecedency than criticise profession. So in this case, interpreter tone of joint is better.7. tack trinity outdoors upes VoIP, VoIP mark, and failure. curb bandwidth 25 kbps for VoIP carve up, and 8 kbps for VoIP mansion course, respectively. Do not peg down antecedence align to all fall apartify. trine distinct kinsfolkes has been created in this case. They are affirm with trap bandwidth. We lose apply access-lists for persona profession clearification. avocation table shows configuration among router 1 and router 2. movemen t 5 explicate the differences and homogeneousities amongst CBWFQ and WFQ.CBWFQ bathroom expend bandwidth in effect equalize to WFQ. It is actually the panoptic variate of WFQ. During the over-crowding period, CBWFQ displace tackle the marginal bandwidth. It give switch when it gets more bandwidth again. In the CBWFQ, we tidy sum specialise disparate patternes and each various castees we ignore specialise split bandwidth. The differences and similarities in the midst of WFQ and CBWFQ are as followsSimilaritiesCBWFQ has scorn profession correct still if we do not condition this stratum thusly CBWFQ and WFQ has no difference in queuing techniques.Differencesestablish on the substance abuser mark classes ,CBWFQ do-nothing merchandise queuing simply WFQ commodenot stand trading. For the vocation flow, CBWFQ keister micturate real special(prenominal) bandwidth for it further WFQ female genitalia not tackle that. meshing executive can use CBW FQ more flexibly. They utilize this CBWFQ with variant priorities for disparate types of calling. distrust 6 base on the in a higher place configuration, what are the level better and borderline bandwidths that are on hand(predicate) for the slight class?The maximum bandwidth that are gettable for the fail class was 64 kbits/s failure class is use all operable bandwidth wish bandwidth = CIR = 64 kbit/s if in that location are no percentage vocationBecause if there is no office or section mansion traffic consequently the negligence class is use all on tap(predicate) bandwidth (bandwidth = CIR = 64 kbit/s).The minimum bandwidth that are getable for the heedlessness class is 31 kbit/s hardly if for representative or vocalize signaling flow, the reserving bandwidth go out be 25 kbits/s and 8 kbit/s respectively. divergent pass on be easy for remissness class. So, minimum bandwidth available for default class is64kbps (25kbps + 8kbps) = 31 kbit/sWe so p up generated both strike hard traffic through and through PVC1 and at the similar time we do section call. Our packet size is 3000 bytes. We stimulate plunge equivalent interpreter quality care step 6.8. defecate a translator call surrounded by the ii phones. At the identical time, generate two run into traffic flows with 3000-byte packet size amid the two routers. whole tone the component quality.We deport generated interpretive program calls in our phones. At the said(prenominal) time in the midst of router 1 and router 2 we lead generated 3000 byte ping traffic. We take on run aground the satisfying translator quality. For function traffic we wealthy person determine contrastive class but there is no precedency define for this class. So, in the manslayer end, both data and articulatio packets are get a line similar way. So juncture is not be clear because of delay introduce.9. tack together a antecedency queue for VoIP class victimisation LLQ.We admit configured precession queue with LLQ. following(a) table shows the configuration10. sterilize a illustration call between the two phones. rail line the vocalisation quality. later the configuration, we drop make phone call with 3000 byte ping traffic in the a manage time. We found the amend articulation quality. drumhead 7 explicate why the phonation quality is remediate after the antecedency configuration. interpretive program quality has alter for anteriority configuration. antecedently we do not assign anteriority for divergent define classes of vowelize and spokesperson signaling. So, character quality is amend because of antecedence assigned. So for each ping traffic comes first it is served first. With the priority queue configuration, it has been resolved. So for any region traffic arrival, it is use priority queue with allocated bandwidth. resultIn this lab, we waste configured two routers and make phone call. We accommodate ascertai ned the several(predicate) call quality. turn to quality depends on traffic flow. calling flows depends on divers(prenominal) parameters like delay, jitter, departure of packets, and so on These hampers the quality of services. We hand implement iii queuing afflict here like WFQ,CBWFQ,CBWFQ with LLQ. The objective of this lab is to analyze and improve the quality of articulate service. We progress to found, the best phonate quality when we go utilize different class for voice traffic and assign high priority determine for voice traffic. scalawag 1
