| The Problems of Public Accessed Computer Laboratories and a Suggestion for These Problems’ Solution | |
| Erzurumlu K, Kaya A | |
| Abstract: In this paper, the cronical problems of computer laboratories which are commonly used on educational institutes will be investigated and an alternative solution to this problems will be provided. In this concept, firstly, PC Based Computer Laboratory’s problems will be investigated in details. Subsequently the Thin Client architecture–which claims that it solves all the problems of PC Based Solutions–will be investigated and the problems of this architecture will pointed out. After this point, our suggestion “Thin Client with Embedded Operating System” architecture will be given in detail and it’s improvements and their disadvantages will be listed. In the last section, cost matrix of a sample computer laboratory which is builded with 3 diffirent architecture will be listed in comperation chart. | |

| Characteristic usage of Turkish Internet Users in Office Environment | |
| Keceli A.S, Erzurumlu K | |
| Abstract: In this paper, a lawyer office’s network and internet traffic will be examined for determining the characteristics of users and network traffic load. In order to do that, some modifications on the lawyers office is made. Firstly, the switch which was previously used, replaced with a smart switch which can mirror traffic to a special port. Later, the office adsl modem is replaced with a modified Linux distribution. These linux device is used as a adsl modem/router for the network. This device also logged every incomming packet including the payload from it’s both interfaces. After a months full run, the data gathered is collected and analized. | |

| Open Source Software Usage on Municipalities; A Case Study: Çankaya Municipality | |
| Vahabdjanov D, Erzurumlu K, Çitak M, Solmaz B | |
| Abstract: As well known, the Open Source Software becomes the leading information technology day by day. There are open source alternatives of the most of the commercial softwares. In this case study, we will examine the open source software usage on the biggest municipality of Turkey; Çankaya Municipality. The IT department of the municipality uses open source software for various reasons and various places. The usage area includes both servers with internet services and desktop usage. In scope of this paper, the reasons of open source software selection and their usage places will be explained in detail for a case study. |

| Building an Open Source Firewall from Strach | |
| Erzurumlu K, Baran O, Kaya A | |
| Abstract: In novadays, a firewall device is a mandatory element of each network. Many companies develop their firewall appliance and their managment softwares. On the other hand, each firewall application has an open source software alternative. In scope of this paper, the implementation of an open source firewall which is been used for last 6 years in Hacettepe University, Computer Engineering Department will be explained in detail with it’s evolutions. |

| Building a Super Computer. Which method is most effective? | |
| Erzurumlu K, Oktaş R | |
| Abstract: In scope of this paper, a Super Computer’s contsruction methods and it’s components will be analized in detail. For the analize, super computer with rack mount servers, super computer with blade servers and super computer with “thin client with embedded operating system” will be investigated. In order to compare the constuction methods, each of the super computer will have same CPU core count. Each of the construction methods, both Hewlett-Packard and Fujitsu’s products will be handled. In the result of this analize, space used per core, cost per core, energy per core is calculated and investigated. |

| A New Approach to Optimizing Network Bandwith and Transfer Rate on Mission Critical Computer Networks: “Network Quality and Resource Manager” | |
| Erzurumlu K, Baran O | |
| Abstract: In this paper, a new approach and solution of the one of the biggest problem on mission critical networks will be discribed. The developed “Network Quality and Resource Manager” ensures the quality of network bandwith and transfer rate on isolated mission critical networks like high resolution IP based security camera surveillence. The “Network Quality and Resource Manager” uses “Quality of Service”, and “Address Resolution Protocol Table” via SNMP protocol. Hence NQRM uses SNMP, it is vendor independent and can work with any network architecture. |

| A New Approach to Tracking Moving Objects on IP Based High Resolution Security Camera Systems | |
| Erzurumlu K, Oktaş R | |
| Abstract: In this paper, a new approach for IP based security camera systems will be described. As well known, the inspection of security footages after an event are time and work force consuming process. These processes can take up to months of work relative to the camera count of the system. With this solution, the moving objects will be indexed while the stream of the camera is recorded and digitally analized. After the indexing process, accessing of the “red sports car’s appearences” can be done in seconds. |

| Lowering Storage Requirements for High Resolution Security Video Systems; Variable Frame Rate | |
| Oktaş R, Erzurumlu K | |
| Abstract: The storage capacity requirements for security systems are directly related to the camera resolution which is used. If the resolution of the cameras higher than Full HD (2.1MP), then the required storage place for the video data becomes enourmous. In novadays, to lower the storage requirements for the video data, changing the frame rate of recorded video after a period of time is used. But with this method, most of the recorded data is removed from the video regardless of it’s needfulness. The approach which will be explained with this paper, describes a new video codec. This codec will not have an predefined frame rate. After a period of recording, an analizing software will be triggered and this software will decide which part of the video will be how much frame rate. These frame rate ratios can be between 0.1 fps and 25 fps. In the last part of the paper, storage requirements of two 3MP security cameras with different video codecs, one of them is indoor and the other one is outdoor will be compared. |

| Comparing System Requirements in Different Resolutions within Security Systems’ Analitics with Image Processing | |
| Baran O, Erzurumlu K | |
| Abstract: In most of the modern digital security systems, analitics softwares are runned for detecting alarms like border passing, illegal parking and etc. Most of the systems runs this software on the recording stream. With the wide range of use of high defination cameras on security systems, the softwares use this high resolution images for the analitics. But this method brings new problems within. The high resolution images’ analicits require more hardware resource then the low resolution. In scope of this paper, authors will investigate the hardware requirements of the same camera which is configured in two settings. First; one stream with full resolution recording/analitics, second; dual stream with full resolution recording and low resolution analitics. |
