Traffic control algorithms in computer networks. Part 2, Simulation researches of the algorithms

Barczak A., Sitkiewicz T.

Studia Informatica : systems and information technology

2009

Vol. 2(13)

5--19

This article is the continuation of the first part entitled Review of algorithms. In the article presented were the author's simulator of a network and the tests performed with its help. In the first part the concept and functionality of the created simulator were described. The concept emerged on the basis of an analysis of existing solutions, as well as needs the created software has to fulfill. The second part of the article depicts the testing environment, i.e. network topology and simulation parameters used during the research. What is more, in the aforementioned part, provided was the comparison of the research run with the use of the author's software and its interpretation.

Review of traffic control algorithms in computer networks

15--26

This paper presents comparison of popular traffic control algorithms in computer networks. It also contains descriptions of functioning of these algorithms. The first part of this paper contains description of evaluation criteria of traffic control algorithms (from system and user viewpoint). The second part of article contains description of new algorithms, which are theoretically improved or brand new, just introduced for practical use. These algorithms are developmental and eliminate disadvantages of already existing algorithms. The third part of this paper contains description of classical algorithms, which are well known, described and researched. It contains also propositions of modifications of classical linear programming algorithms. These modifications are for adjusting these algorithms to described problem.
