To carry out three guidelines of university (teaching-learning, research, and community service), there is needed an internet service which can support it. Band-width management is very necessary in the Department of communication and computer. Beside it regulates the demand of every individual, it also regulates the data traffic is remained running smoothly. There has not been the band-width management in a network will cause band-width mastery in some users. This study intends to evaluate the performance of band-width management by using Hierarchical Token Bucket (HTB) and Peer Connection Queuing (PCQ). The capacity of Band-witdh is 2 Mb and there are 5 clients. The performance test uses tools iperf as the traffic generator to be able to know the Quality of Service (QOS) from HTB and PCQ. Parameter of QOS consists of throughput, packet loss, delay, and jitter. Results of the two methods will be compared with the weighting due to the Tiphon standard. Result shows that analysis of QOS by 5 clients and band-witch of 2 Mb and uses HTB parameter produces the packet loss in average of 0%, mean of throughout is Mb by using cable and without-cable, delay by using media of cable is ms, without cable is ms, jitter by using cable is ms, without cable is ms. For parameter PCQ method produces the packet loss in average of 0%, mean of throughout with cable is Mbs, without cable is Mbs, delat with cable is ms, without cable is ms, jitter with cable is ms, without cable is ms. KEYWORDS: throughput, packet loss, delay, jitter INTRODUCTION Network of computer is as a union of softwares such as hub, switch, router, or the oather network software which is related by using certain communication media [1]. The device that is related by network is also mentioned as node. Internet is as an information media of global computer which can be said as the most sophisticated technology nowadays if it is compared with the other information deviation media like media of electronic and printing because the information on the internet is widely in the world and can be accessed fastly and there is from anywhere. Band-width management is very nacessary in the network of communication and computer. It is either regulating the demand of every individu or so the data traffic is remained running smoothly. There has not been the band-width management in a network will cause bandwidyh mastery in some users. Principally, PCQ (Peer Connection Queue) uses the queuing method for making the same with the usaed band-width on the multiple client. On PCQ microtic inside there has been installed the default and it is as the program for regulating the network traffic of Quality of service (QoS). By using flow identifiers (dst-address, dst-port, src-address or src-port) for separating the traffic into sub stream. Hierarchical Token Bucket (HTB) is as technique of package schedulling which is of late introduced for the Limix based router and it is developed by Martin Devera in the end of 2001 [2] to be projected as the option (or changer) of schedulling mechanism which is more still used now such as CBQ. This study intends to know the difference of band-width distribution result by using Hierarchical Token Bucket and Peer Connection Queuing with cable and without cable. In addition, it intends to find the result of QoS on band-width management by using the methods of PCQ and HTB such as throughout, pocket loss, delay, and jitter. MATERIALS AND METHOD Comparison analysis Comparison is as the action to compare one or many objects with comparing tool. From the comparison, it can be obtained the equations and differences from the object or the objects ago with the comparing tool or from one object to the other object. *Corresponding Author: Fransiskus Xaverius Manggau, Department of Informatics Engineering, University of Musamus, Merauke, INDONESIA. fransiskus@unmus.ac.id 1

2 Manggau, 2017 Comparation analysis is used for comparing the average between two or more data samples group> The base assumption in comparition analysis is that the data variable which will be compared has to be followed Normal distribution [3]. QOS (Quality of Service) According to Kamarullah [4], from the networking side, QoS is based on the ability to give the different service to the network traffic with the different classes. The end aim of QoS is to give better and planned network service by controlled dedicated band-width, fitter, and latency; and to increase the characteristic loss. In addition, QoS is as the ability in guaranteing the sending of important data flow or as the collection of some performance criteria which determines the level of user or service satisfactory. There are some methods for measuring the quality of connection like band-width consumption by user, latency, losses, and availibility in Quality of Service. Management of band-width Band-width is number of data or information which can flow from a place to the other place in a network and certain time. Band-width can be used for measuring either analog or digital data flow. The unit that is used for band-width is bit per-second or it is oftenly abbreviated as bps [5]. Management is as the process of resource usage effectively for reaching the objective that has been determined [6]. Band-width management is as the accurate process of allocating from a band-width for supporting the demand or the need of application or service [7]. HTB (Hierarchical Token Bucket) Hierarchical Token Bucket (HTB) is as the technique of package schedulling wgich is used by some Linux based router which is developed at first by Martin Devara [8]. The work base of HTB as almost the same as the queuing dicipline of CBQ even the system block diagram between CBQ and HTB is not different, however on general schedulling of HTB uses the mechanism of Deficit Round Robin (DRR) and on the feed back block, estimator, HTB do not use Exponential Weighted Moving Average (EWMA) but it uses the Token Bucket Filter (TBF). Figure 1 presents Token Bucket Filter. Gambar 1 Deficit Round Robin Figure 1 Token Bucket Filter PCQ (Per Connection Queuing) PCQ is introduced for optimizing the big QoS system which there are most of queuing that the same for some sub-flow. For-instance: sub-flow can download or upload for a certain client (IP) or connesction to server. Algorithm of PCQ is very simple, in the beginning it uses the classiying operator for differentiating a sub-flow from the other flow, so it is valid the queuing size of individual FIFO and the limitation on every sub-flow, so the whole group of sub-flow together and it is valid for global queuing size and limitation. Parameter of PCQ Pcq-classifier (dst-address, dst-port, src-address, src-port; default: ""): selstion of sub stream identifiers. Pcq-rate (number): available maximum of data rate for each sub-steam Pcq-limit (number): queuing size of sub-stream (KIB). 2

3 J. Basic. Appl. Sci. Res., 7(10)1-10, 2017 pcq-total-limit(umber): maximum number of queuing data in the whole sub stream (KIB) Iperf Iperf is used as the generator traffic, Iperf is divided into two parts such as server and client, the function is for flooding the network, so it can be determined the network quality. Iperf is as the tools which is used for knowing the performance of a network by knowing maximal band-width and maximal data transfer rate. Description and analysis of design Analysis of hardware demand For supporting the fluency of planned system, it is needed hardware. The hardware which is needed is based on the demand which has to be measured up as follow: A. Server 1. Processor of 1.60 Ghz or the proportion 2. Hard disk of 160 GB. 3. Memory of 1GB. 4.

Processor of 1.60 Ghz or the proportion 2. Memory of 512 MB 3. Hard disk of 120 GB 4. VGA Card of 64 MB (onboard) 5. Mouse, keyboard, monitor, and printer as the interface tool Analysis of software For supporting the fluency of planned system, it is needed hardware. The hardware which is needed is based on the demand that has to be measured up as follow: 1. Microtic reuter OS is as operation system which is as the network router. 2. Win box is used for configurating PC riuter microtic. Win box is as the application which can be directly excecuted without installing. Scenario of research This study is due to the demand in University of Musamus which is some places hace accessed the internet by using hotspot login and some rooms use cable network or LAN. This study uses the scenario of test as in Figure 2 and 3 below. Figyre 2 Scenario of test for PCQ method 3

4 Manggau, 2017 Figure 3 The scenario of test for HTB test Based on the scenario as above, for analysis the result of QOS measuring, it is used the formula as follow: 1. Packet Loss Packet Loss is as a parameter which illustrates a condition that indicates the total number of loss packet. It can be happened because there is collision and congestion on the network Throughout Throughout is as the rate of effective data transfer which is measued in bps (bit per-second) 2 3. Delay Delay is a time which is needed by packet for reaching the aim because there is queuing or taking the other route for avoiding the stagnation Jitter Jitter is caused by the variation of queuing in the period of data processing and in re-schedulling the packets in the end of jitter travelling...4 RESULTS AND DISCUSSION Configuration of reuter microtic To configurate the reuter board microtic, it is used the application of winbox. The steps are as follow: 1. Login to microtic through remote winbox 2. Setting Ip address on the interface microtic which will be used by IP Address-add address 3. Setting getaway on microtic IP-routers-add gateway 4. Setting NAT di IP Firewall NAT chain: src-nat Action: masquerade 5. Setting Ip DNS IP DNS. Carrying out on the both of router which will be used, the next step is to apply the management band-width on the both of router by using the methods of HTB and PCQ on the different router. Management bandwidth with HTB method 1. Setting Mangle Mangle has the function for marking a connection or data packet which is through router, enter to the router, or going out from the router. Figure 4 presents the menu farewall mangle with HTB method. 4

Setting Queue Tree Queue tree is functioned to limitate the band-width on the microtic which has 2 connection of internet because the packet marh is more functioned than in simple queue. It is used to limitate only one way connection either download or upload. Parent is used for determining the selected queue is functioned as child queue or not. There are some options for default in parent queue tree which is usually used for the queue head. Packet mark is used for marking packet which has been marked in Ip firewall mangle. Figure 5 presents the menu queue trre list HTB. Figure 5 Menu Queue Tree List HTB Management band-width with PCQ method 1. Setting Mangle Figure 6 presents the firewall mangle with PCQ method. Figure 6 Firewall Mangle with PCQ method 2. Setting Queue Type In this actibity, queue type is added by queue type upload and queue typr download which the type of ipload and download is PCQ (Peer Connection Queue) which can be used for dividing or limitating the traffic for multi-users that uses the cable network. However for queue type hotspot, upload and queue type hotspot download for user uses dynamic without cable network. Figure 7 and 8 presents the queue type.pcq download and upload, Figure 9 and 10 for the hotspot. 5

Setting Simple Queue On the regulation of simple queue name internet is as the parent which is the band-width that is allocated is as 2M for upload and 2M for download, then it is divided into every child hospot Rx max is 2 M and Tx max is 2M, but for Rx limit is 1M. It means if from the three child, only child hotspot that access the internet, so the band-width which will be accepted the child hotspot will full of 2 M and of there is three child together to access, so it will only obtain the band-width of 1 M. Figure 11 presents the menu of simple queue lis PCQ. Figure 11 Menu of Simple Queue List PCQ RESULTS OF MEASUREMENT Based on the scenario of Figure 2 and 3, it is obtained the measuement result by using tools iperf with the methods of HTB and PCQ. Iperf is used as the traffic generator. Iperf is divided into two such as server and client and the function is for flooding the network so it can be determined the quality of network. Client is used for carrying out the packet to server, sending packet can use comment: # enter to directory iperf. #iperf.exe c <alamat server> #iperf.exe s -c It means as the mode client, -s it means mode server but i is iteration. Figure 12 Measurement result of mode server 7
