“…Deflection routing can efficiently tackle the problem without added hardware effort and enables 70% and more utilization at realistic loss rates for common channel numbers and uneven (dynamic) load distribution [13]. Fibre delay line arrays (FDLAs) can be added to solve the contention problem [2,[14][15][16]. Special (optional) burst assembly schemes could be applied to allow truncation of contending bursts.…”

“…Contention, or more precisely the statistical burst collision potential that results inevitably from the presumed one-way signaling, challenges OBS. The utilization may be increased to competitive levels if contention resolution mechanisms are considered [2]. In addition, specific service requirements can be served better with OBS, if we look at OBS more openly and assume two-way signaling possible for certain traffic flows.…”

Focusing on the principles and the paradigm of OBS an overview addressing expectable performance and application issues is presented. Proposals on OBS were published over a decade and the presented techniques spread into many directions. The paper comprises discussions of several challenges that OBS meets, in order to compile the big picture. The OBS principle is presented unrestricted to individual proposals and trends. Merits are openly discussed, considering basic teletraffic theory and common traffic characterisation. A more generic OBS paradigm than usual is impartially discussed and found capable to overcome shortcomings of recent proposals. In conclusion, an OBS that offers different connection types may support most client demands within a sole optical network layer.

Esta es la versión de autor de la comunicación de congreso publicada en: This is an author produced version of a paper published in: Abstract. This chapter summarises the activities on optical packet switching (OPS) and optical burst switching (OBS) carried out by the COST 291 partners in the last 4 years. It consists of an introduction, five sections with contributions on five different specific topics, and a final section dedicated to the conclusions. Each section contains an introductive state-of-the-art description of the specific topic and at least one contribution on that topic. The conclusions give some points on the current situation of the OPS/OBS paradigms.

“…Being regarded as a promising technology to support the future IP over WDM networking, OBS has received a lot of attention [3]. Since TCP is the dominating protocol for data transmission in Internet today and will likely remain so in NGN, recently the performance of TCP over OBS networks has been investigated [4][5][6][7].…”
