Optical Burst Switching (OBS) is perceived as the most favorable switching method for the next generation all optical networks to support the growth of the number of Internet users and to satisfy bandwidth demands for greedy-bandwidth applications which are in continuous growth. OBS consists of an edge node and a core node. The edge node is responsible for burst assembly which is the first process in an OBS network. Currently, there is only one review paper for burst assembly; the paper is limited in number of techniques reviewed. In this paper, we have undertaken a comprehensive review of burst assembly techniques proposed for OBS where techniques are reviewed by category. The aim is to identify strengths and weaknesses of these techniques. The analysis of the paper will assist researchers in finding problems; thus, a significant amount of time will be saved which can be used in developing appropriate solutions for OBS networks.
Penggunaan internet yang meluas dan berterusana menyebabkan kenaikan trafik dalam talian. Teknik Optical Burst Switching (OBS) boleh dikatakan sebagai penyelesaian kepada masalah trafik di dalam rangkaian internet. Namun demikian, terdapat beberapa isu dalam rangkaian OBS. Salah satu isunya adalah untuk meminimakan offset masa tunda dan untuk mengatasi masalah ini, terdapat banyak penyelidikan dilakukan menggunakan berbagai cara dan teknik. Laporan ini menyediakan penerangan mengenai skema yang telah digunakan disamping menghuraikan mengenai kelebihan dan kekurangan skema yang telah sedia ada. Kata kunci: OBS; offset time The dramatic and continuous use of the Internet has increased the network traffic that is needed to be transferred through the Internet network. Optical Burst Switching (OBS) has met the requirements of such demands and is considered as a solution of the issues present in Internet networks. However, there are still some issues in OBS network have not been solved. Minimizing offset time delay is one of these concerns and a lot of research has been introduced in order to solve this issue through using various ways or schemes. In this paper, a description of these schemes and their advantages and disadvantages is presented. Key words: OBS; offset time
