Kampus ITS, ITS News — To optimize data transfer from one device to another, the time delayed in the computer network must be calculated properly. This was then elaborated deeper in the ELECTICS web-seminar series as a form of collaboration between Institut Teknologi Sepuluh Nopember (ITS) with California State University (CSU) last Friday (26/6).

The event, which was held as an actualization of the collaboration between the ITS Faculty of Intelligent Electrical and Informatics Technology (ELECTICS) and the Department of Computer Science of CSU in early June, invited Professor Khondaker Salehin from CSU as a speaker. “This web-seminar activity is the first milestone of the collaboration we formed,” revealed the Secretary of the Academic and Student Affairs Department of ITS Informatics Department, Ary Mazharuddin Shiddiqi, Ph.D.

In the first topic entitled Improvement of Delay Estimation over End-to-End Paths, Professor Salehin explained the concept of time delay in computer networks. The computer network itself is a technology that can connect two or more computers with other computer support devices so that it is possible between computer units to share data.

Furthermore, this computing network can be connected with one another using cable or wireless media. One example of a computer network that is commonly known as the internet. Meanwhile, a time delay occurs in the process of transmission from one point to another point as the destination. “The delay is an inherent parameter in internet infrastructure,” identified this Indian professor.

In his observations, this man, who is familiarly called Salehin, explained that the measurement of the duration of time delay on a computer network by using conventional methods through sending Ping packets was considered to be imperfect. This is due to an error source in the workstation, which is an inaccurate measurement of Packet Processing Time (PPT).

Related to this, Salehin then discussed his research that uses a scheme to measure PPT without special hardware that was presented using empirical data obtained from testing on the network. “The estimation of queue delay on internet routers is important to identify if you want to get a more accurate characterization of delay time,” he informed.

This first topic also discusses a self-sufficient scheme to calculate the delay time for all routers in an end-to-end path. Numerous studies in the scope of PPT calculations and time delays as well as other computer network fields were also presented to strengthen the research that has been done. “I am open to accepting new ideas within the scope of machine learning, autonomous vehicles, privacy, or even sensor networks,” Salehin emphasized.

This bespectacled man also stated that he offers opportunities for anyone interested in exploring the field of computer networks and wanted to carry out further collaboration. Whether it’s in writing a paper or running a project about fundamental theory or the application of computer science in everyday life. (rys/lut/ory/ITS Public Relations)
