This paper presents an Erlang reduced load model to analyze Optical Burst Switched Grid networks. The model allows the evaluation of job blocking probabilities, in which blocking occurs in both the transport network and the resources where jobs are processed. Additionally, a novel routing strategy is introduced to improve the usage efficiency of the existing infrastructure.

Distributed applications or workflows need to access and use compute, storage and network resources simultaneously or chronologically coordinated respectively. Examples are distributed multi-physics simulations that use the combined computational performance and data storage of multiple clusters. A coordinated reservation and allocation of the resources is a prerequisite for the efficient use of such resources. This contribution describes the components of a system that provides Grid users with this functionality.

For demanding Grid applications that use resources at different cluster sites a reservation mechanism can ensure the availability of resources to guarantee a certain level of QoS. Besides computational and storage resources, we see the network as a reservable resource as well. Our approach to QoS is to schedule resources in the network for exclusive usage in advance. For this purpose, a flexible reservation mechanism is needed to meet the requirements of Grid applications and schedulers.

In this study, we present a thorough analysis of the job arrival process in the EGEE infrastructure and of the time durations a job spends at different states in the EGEE environment. We define four delay components of the total job delay and model each component separately.

This paper addresses the problem of survivable lightpath provisioning in wavelength division multiplexed networks taking into consideration the optical signal performance degradation triggered by the physical impairments of transparent optical networks as a routing constraint. This work proposes a resource efficient provisioning scheme that takes into consideration both working and protecion traffic.

The usage of static timeslots is a well-known approach to handling advance reservations in the scope of Grid resource management. In this paper we enhance the timeslot-based approach by introducing dynamic timeslots and the notion of granularity. The main contribution is the development of an analytical model of the interrelation between user and system parameters in order to describe their impact on system efficiency and responsiveness.
