A Zero Burst Loss Architecture for star OBS Networks

Abstract

Performance studies point to the fact that in an OBS network, the link utilization has to be kept very low in order for the burst loss probability to be within an acceptable level. Various congestion control schemes have been proposed, such as the use of converters, fiber delay lines, and deflection routing. However, these schemes do not alleviate this problem. It is our position that in order for OBS to become commercially viable, new schemes have to be devised that will either guarantee zero burst loss, or very low burst loss at high utilization. In a previous paper [Ij, we described effective zero burst loss schemes for OBS rings. In this paper, we present a zero burst loss scheme for star OBS topologies. Further research into the topic is required.

A decision algorithm for efficient hybrid burst retransmission and burst cloning scheme over star OBS networks

“…In this paper, we focus on a class of OBS networks that use an overlaid-star topology [12], [13], [14], [15], [16]. The overlaid-star topology forms a logical mesh, where each edge node is a member of at least two stars in order to have a minimum of one protection path in the event of core or fiber link failure.…”

Dalgaboyu Bölümlemeli Çoğullama (DBÇ) Üzerinde Optik Çoğuşma Anahtarlama (OÇA) ve Çoğa Gönderim

“…Çoğuşma anahtarlama, iyi bir istatistiksel çoklama performansı sağlayabilmek için ya büyük oranda optik tamponlara yada optik dalgaboyu dönüştürücülere ihtiyaç duyar. Günümüzde optik tampon olarak gecikme hatları kullanılmaktadır ancak çoğuşma anahtarlamada dalgaboyu dönüştürücüler kullanılarak tamponlama ihtiyacı azaltılmaya çalışılmaktadır [13].…”
