“…In this chapter, we will investigate the performance of the proposed SLA under bursty traffic. For that matter, we will use the Interrupted Poisson Process (IPP), as described in [83,84], as an arrival process. The IPP is an ON/OFF process, where both the ON and the OFF periods are exponentially distributed.…”

“…The IPP arrival process is an ON/OFF process, where both the ON and the OFF are exponentially distributed. The squared coefficient of variation, c 2 , of the packet inter-arrival time characterizes the burstiness of the packet arrival process [83,84]. This coefficient is defined as the variance of the packet inter-arrival time divided by the squared mean packet inter-arrival time.…”

“…Grid computing is also considered as desired applications over OBS networks [14], [15]. In the Grid over OBS, each Grid job is encapsulated into a burst, and then it is transmitted to a remote site with its corresponding control packet containing requirements such as deadline and necessary storage.…”

In this paper, we consider consecutive burst transmission with burst loss recovery based on Forward Error Correction (FEC) in which redundant data is transmitted with multiple bursts. We propose two burst generation methods: Out-of Burst Generation (OBG) and In-Burst Generation (IBG). The OBG generates a redundant burst from redundant data, while the IBG reconstructs a burst from an original data block and a part of the redundant data. For both methods, the resulting bursts are transmitted consecutively. If some bursts among the bursts are lost at an intermediate node, the lost bursts can be recovered with the redundant data using FEC processing at the destination node. We evaluate by simulation the proposed methods in a uni-directional ring network and NSFNET, and compare the performances of the proposed methods with the extra-offset time method. Numerical examples show that the proposed methods can provide a more reliable transmission than the extra-offset time method for the OBS network where the maximum number of hops is large. Moreover, it is shown that the end-to-end transmission delay for our proposed methods can be decreased by enhancing the FEC processor or by increasing the number of FEC processors.

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.
