© 2021 IEEE.Network monitoring is one of the key aspects to ensure communication reliability in case of failures and malicious activities and has several design issues depending on the system characteristics. As traditional monitoring solutions usually rely on periodic updates between the network controller and ordinary nodes, scalability remains a challenge, especially for complex systems. A recent solution, the In-Band Network Telemetry (INT) framework, allows data packets to probe the nodes while traversing the network reducing the overhead between the controller and other nodes. Accordingly, effective use of the INT framework is now a design problem to (i) minimize the control overhead, (ii) guarantee the freshness of telemetry information, and (iii) minimize redundancy. In this paper, we propose a heuristic, Graph Partitioned INT (GPINT), to find balanced paths to forward in-band telemetry information to satisfy these three requirements. We present an extensive analysis of our approach and compare it with a recent study that uses Euler's method for path generation. Our numerical results show that GPINT outperforms its opponent in terms of all three requirements.

A faster intrusion detection method for high-speed computer networks
Tarım, Mehmet Cem; Schmidt, Şenan Ece; Department of Electrical and Electronics Engineering (2011)
The malicious intrusions to computer systems result in the loss of money, time and hidden information which require deployment of intrusion detection systems. Existing intrusion detection methods analyze packet payload to search for certain strings and to match them with a rule database which takes a long time in large size packets. Because of buffer limits, packets may be dropped or the system may stop working due to high CPU load. In this thesis, we investigate signature based intrusion detection with sig...
Implementation and Evaluation of Age-Aware Downlink Scheduling Policies in Push-Based and Pull-Based Communication
Oğuz, Tahir Kerem; Ceran Arslan, Elif Tuğçe; Uysal, Elif; Girici, Tolga (2022-5-01)
As communication systems evolve to better cater to the needs of machine-type applications such as remote monitoring and networked control, advanced perspectives are required for the design of link layer protocols. The age of information (AoI) metric has firmly taken its place in the literature as a metric and tool to measure and control the data freshness demands of various applications. AoI measures the timeliness of transferred information from the point of view of the destination. In this study, we exper...
Effective Communicatıon Of User Research Outcomes In Design For Well-Being: Adaptation Of The Design Well-Being Matrix In A Pregnancy Case
Günay, Aslı (Middle East Technical University, Faculty of Architecture, 2020-6-30)
Effective communication of user research deliverables plays a crucial role during all design processes to effectively and meaningfully inform design decisions. As newly introduced materials, such as frameworks and tools, in emergent fields are actually mediums for communicating information in different phases of research, effective communication of them would foster the development of a shared and established language, and thus, robust progression of these fields. This paper investigates effective communica...
Improved Software Reliability Prediction by Using Model Stacking and Averaging
Karaomer, Rabia Burcu; Yet, Barbaros; CHOUSEİNOGLOU, OUMOUT (2019-01-01)
Software reliability is an important factor for the success of a software project. Accurate modelling of software reliability enables estimation of remaining defects, the timing of deployment and required future effort. These factors contribute to successful planning of project schedule and resources. A number of software reliability prediction models have been proposed, each with different assumptions regarding software defect introduction and discovery. The performances of these models differ depending on...
