An Efficient Advance Resource Reservation Protocol for Lambda based Grid Networks

Motivation

In optical networks, an important technology used currently in data-intensive grid computing, the advance reservation of lightpaths is key to guaranteeing that enough wavelengths will be available when needed. Advance reservation is an important part of grid computing. It guarantees that resources will be available at a pre-determined time to participate in the execution of a grid application. We should distinguish the clear advantages of having early confirmed resources available for our applications, so we are working to improve having those confirmations efficiently.

Current Progress  

Lambda-Grids are virtual aggregations of geographically distributed computational elements tightly coupled with Reservation of lightpaths but its wide scale utilization has not yet been attempted. Consequently, there is a pressing need to not only provide a flexibility in the of options provided by the interface for setting up the lightpath according to the specific need of users which can be used to study the interplay of advance reservations with other strategies used for network resource optimization. The pattern of user requests in an advance reservation scheme is significantly different from the pattern in an on-demand network environment. Advance reservation requests are not only a function of the time at which they arrive but also of the time in the future for which the reservations are requested. Our goal is to improve the model for these requests for systems that support advance reservations.
